What Materials Make the Best Shingles for the Pacific Northwest?

The Pacific Northwest is famous for its cool and temperate climate, with clouds, wind, and rain regularly doing a number on every rooftop in the area. During the winter, ice and snow can give these same rooftops a further beating, not to mention wear and tear from leaves, falling branches, and other debris carried by all of this inclement weather.

Of course, even a pleasant sunny day without a cloud in the sky can take its toll: the sun’s ultraviolet radiation beats down on rooftops and causes them to deteriorate over time.

Because weather is so hard on rooftops, particularly in the Pacific Northwest, you need to make sure you have the right materials making up the shingles of your rooftop. In this article, we’ll look at why composition shingles are the best shingles for Pacific Northwest homes.

The Parts of Your Roof

A roof is made up of several different elements. It begins with a wooden frame called fascia, with a wooden decking built on top of that. These parts give the roof structure. The rest of the materials used to make up the roof are used to protect the home from the elements.

Attached to the wooden decking is a thick layer of felt called the underlayment. Attached to the underlayment are the flashing, which helps direct water off the roof, and the shingles.

What Are Roofing Shingles?

The shingles on your roof are its first line of defense against the elements. They protect from sunlight, rainwater, and other debris. Shingles are flat, rectangular pieces that fit over each other in an overlapping pattern. They are attached starting at the base of the roof and toward the top of it.

Shingles can be made from many different materials. Stone such as slate is also popular as is wood. As you may imagine, these materials can be expensive which is why most homeowners opt for less expensive options.

Finding the Right Roofing Materials for Your Home

Fortunately, there are options for shingles that marry cost savings with the added aesthetic appeal of slate shingles. Composition shingles, which are also known as asphalt shingles, are one of the most popular choices available. They are usually made from a fiberglass mat that is covered with a layer of tar and a mixture of granules to ensure a lightweight, inexpensive, waterproof protective layer for the roof of your home. Certain composite shingles are created to have the appearance of slate shingles while still costing a fraction of the price of the more expensive material.

If your building happens to have a flat roof, rather than a sloped one, the best material is probably an artificial membrane called TPO, which stands for thermoplastic olefin. This material is made of a polymer base created from the aforementioned thermoplastic. On top of that is a reinforced fabric center, and on top of that, a top ply made from thermoplastic polyolefin. This roofing material works well for flat roofs because it’s highly UV resistant: flat roofs deal with the sun’s rays even more than sloped ones do. They are also likely to have less effective water drainage. TPO materials help prevent leaks.

What Happens When the Shingles Are Lost or Damaged?

Shingles are durable, but inclement weather can still damage them. Heavy winds will pull shingles off of the roof and blow them away; ultraviolet solar radiation will wear them out; and ice will form underneath them, eventually leading to leaks.

If the shingles on a rooftop are lost or damaged, air and water will eventually leak through the holes in the roof. If air gets in, it can dramatically drive up energy costs in a home by reducing the efficiency of the heating and cooling systems. If water gets through one of the holes in the roof, it can encourage the growth of mold and dry rot. Water can also cause catastrophic property damage, possibly costing thousands of dollars to repair, and all because the roof was missing a few hundred dollars’ worth of shingles.

As you may expect, the problem of lost and damaged shingles is of particular concern in climates like the Pacific Northwest. The alternating wind, rain, and sunlight of this climate can put a lot of extra stress on rooftops, perhaps more so than in other climates in the United States. This is why the best shingles for Pacific Northwest homes are composite ones, or TPO for flat roofs. They are resistant to all of these weather conditions and are relatively inexpensive to replace.

Who Can Repair and Replace Lost and Damaged Shingles?

Properly cared for, roofing shingles, generally last about 20 years. However, they’re still susceptible to damage. Heavy winds and constantly falling leaves and branches are a risk to shingles, no matter how well-maintained they are. When you do lose a few, you don’t want to leave bare patches on your rooftop. Not only does it look unappealing, but it also puts the home at risk of further damage from the weather.

Because of this, it’s a good idea to have a great roofing contractor you can contact in case of a roofing emergency. It’s also a good idea to know who your contractor is before the emergency actually occurs. Do a little research into who is available in your area and how they have been reviewed by other customers.

Your best option is to look for a company like Interstate Roofing. We have years of experience in the industry. We’ll be able to address emergencies, as well as routine roof repairs and maintenance. If you’re interested in any aesthetic work or in roofing for a business, we’ll be able to do the job for you quickly and effectively, ensuring you get the most out of your roofing materials for years to come.


5 Great Reasons to Skip DIY Roof Repair and Hire an Expert

Although a broken tile or shingle or small leak might seem like an easy fix for someone with basic carpentry skills, there are myriad things that can go wrong with a DIY roof repair job. There are simple factors like materials that can shape the way a fix might go, or there can be more impact-heavy events like weather, including both heavy winds and rain. And while it might start as just a small leak or a missing or broken shingle, even attempting to work on the roof can end negatively for both the worker and the roof.

As soon as you notice a problem with your roof, it might seem like a good idea to find a ladder and assess the situation yourself, but there are some very serious potential issues with attempting a DIY roof repair. Like your home’s foundation, the roof is also a crucial part of your home, as it keeps you dry and safe from the elements. It has a vital role in the structural integrity of your home and plays an active part in protecting the people who live under it.

When you notice that your roof needs some repairs or updates, your best option is to call a professional roofing company, such as Interstate Roofing, so they can make sure your roof is in tip-top shape and you avoid some of the negatives that can come along with a DIY roof repair. Read on for a few examples of great reasons to skip such projects.

1. Safety Concerns and the Risk of Injury

The first concern is regarding the height at which the repair would take place. Working at a great height is always dangerous and carries the risk of severe injury or even death. Professionals are required to wear and use practical safety equipment throughout the duration of their time off the ground. In addition to the risk of hurting yourself, if the roof isn’t repaired correctly, there is a chance part of what was “fixed” falls off and either hurts someone or causes damages to property below.

2. Invalidation of Warranty

Even if a DIY roof repair isn’t your preference, you may lean toward sorting issues yourself because it seems logical and practical to do so. But it might shock you to learn that if your roof is under warranty, and if you decide to attempt a repair yourself, it’s possible that the simple act of trying to fix something will invalidate and nullify the warranty. This would make it impossible to use the warranty on a future—potentially bigger—repair.

3. Exacerbate the Damages to the Roof Top

Not everyone is meant to be a carpenter or roofer. And that’s okay. When you’re tempted to do the job yourself, consider the fact that some attempts at fixing the roof might actually lead to a more disastrous issue, thereby requiring a bigger fix. It’s imperative to take into account the opinions and input from a professional, as there might be something unseen by you that they discover or simply can recognize from experience. If your fix attempt fails, it could very well cost you more to get a secondary fix by professionals.

4. Time

People who work in roofing for roofing companies spend a lot of time on a roof and have spent a lot of time developing and perfecting their craft. The amount of time that it takes a professional to complete a job versus someone intent on going the DIY route is very significant. It is much easier for someone with years or decades of experience to complete a fix atop a residential or commercial building. If you don’t know what you’re doing, it can take you a lot longer to do it, even learning as you go. Then, there are additional costs beyond the time of the physical effort.

5. Material Costs

There are material costs, too. While the actual cost for materials is about even, if you’re not trained to fix a problem with the roof, there is a chance that you will create further damage and that these issues will also need to be repaired, creating yet more expenses to cover. The cycle has the potential to continue, so it makes a lot of sense to get a professional to do the job correctly and timely on the first go. Their work is also usually covered by a work guarantee, so if there are any issues that spring up later, the work will be attended to quickly and without any extra unplanned expenses.

Beyond the sheer amount of experience that a professional roofer has compared to a novice, the fact of the matter is that roofers know how to “read” the roof. That is, while they’re up there, it will be possible for them to inspect the roof to see if anything else is not up to standard. It can be that this simple practice can pinpoint current minor issues in order to prevent future problems. Again, a benefit to this is to save time and money and to have a safe space above your head. A roof that does its job well and protects those inside.

How To Fix Roof Flashing

Water damage is one of the biggest, most insidious threats not only to your roof but to the rest of your home as well. Of course, that’s what your roof is for in the first place: keeping water out while keeping a comfortable temperature inside. To this end, a roof is actually a fairly complex system, with many parts that need to be in good condition in order to guard the home optimally.

The shingles—the top layer—usually get the most attention, but the roof flashing is just as important, and when it becomes damaged, catastrophic problems can follow. Fortunately, we’re here to tell you what you need to know about how to fix roof flashing.

What Is Roof Flashing?

Roof flashing is a thin sheet of metal that connects various parts of the roof, and it’s placed where it is in order to prevent leaks through vulnerable areas. These might be the joints and valleys of the roof or around the chimney or to protect drainage pipes. The metal flashing must extend underneath the shingles and other parts of the roof so that it can prevent water seepage even if damage occurs to the upper layers.

Flashing can be made of several kinds of metals or other materials, although aluminum and stainless steel are the most common due to their ability to resist corrosion as well as their relative inexpensiveness. Occasionally, copper is used because of its ability to provide a decorative element, although it is much more expensive. Roof flashing is very durable, being more resistant to weather and temperature than other elements of the roof. However, heavy winds and other severe conditions can still damage it.

Types of Flashing

There are several types of flashing utilized, depending on which element of the roof needs to be protected. Continuous flashing is one single piece of metal that extends down the entire roof. While base flashing, also known as two-part flashing, is made of multiple pieces that connect to each other, usually in the form of a membrane with metal flashing on top.

If the flashing needs to go in multiple directions, counter flashing or step flashing might be used. In either case, caulk or sealant is used to prevent leaks from forming around the seams of the flashing.

Repairing Small Damage

Often, the damage that occurs to flashing is very small. For example, repeated dripping water may cause a small hole to form as a result of corrosion. This type of damage is relatively easy to fix. In most cases, you can simply use a small amount of roofing cement to plug the hole. If it’s a little larger—up to around three-quarters of an inch—you will first need to sand away the corroded part. You can do this with a wire brush or heavy-duty sandpaper.

You’ll then need to cut a small piece of aluminum (or steel or whatever material the flashing is made from) and then use roofing cement to use that piece as a patch over the damaged area. This patch should then be covered with another layer of roofing cement to seal it against further damage.

If the Damage Is More Extensive

Roof flashing is extremely durable and can last for many years with proper care. However, proper care is the key term here. Your flashing, as well as the rest of your roof, should be checked periodically by a professional roofer. They will catch problems before they become worse.

If, despite your best efforts, a larger area becomes damaged, you will need to replace the flashing entirely. Make sure that you take safety into consideration before you do this. Wear the proper attire, including gloves, closed-toe shoes, and a safety harness. Have a sturdy roofing ladder and don’t stand anywhere if you are not totally sure it is safe. Also, have at least one other person to serve as your spotter, assisting you as an extra set of eyes and hands.

You will need to start by removing the old flashing, which should begin by ripping away the old caulking that lines the flashing. You’ll then need to pry away the old flashing, using a hammer or other tool to remove the roofing nails.

You will then be able to replace the flashing with the new material, which can be a tedious task, especially with continuous flashing. As you go along, seal the flashing with caulking that is designed for use on roofs. You will also want to cover the nail heads with the same roofing cement you’ve been using for patching the smaller holes.

Similar methods can be used for replacing the flashing that surrounds chimneys and vent pipes. Bit by bit, you’ll pry them away and replace them with new flashing. As always, ensure that there’s plenty of sealant because any weak areas can allow water in, which can then shorten the life span of your roof as well as creep into your home and cause water damage.

Don’t Be Afraid to Call a Professional

Learning how to repair roof flashing is a big job and one that’s quite labor-intensive. That’s in addition to it potentially being dangerous if done improperly. So if you are uncertain about your ability to perform the task, contact a professional and ask them to do it instead.

Often, people attempt to DIY jobs to save money on a task, but if the task is done incorrectly, it may end up costing you more money in the long run. The fortunate thing about roof flashing is it likely won’t have to be replaced all that often—especially if it’s well cared for—because it can usually outlive the other elements of your roof.

Contact a reliable contractor who has been in the business for years, such as Interstate Roofing. They will be able to perform regular maintenance as well as larger tasks and even emergency tasks if necessary.

Do I Need to Replace My Roof to Add Solar Panels?

Solar power is an efficient, environmentally friendly form of power that more and more people are incorporating into their homes each year. By adding solar panels to your home, you can cut down on your power bills while doing your part for the earth. It’s an appealing prospect, but if you’re considering adding solar panels to your home, you should know the effort required.

The fact of the matter is, you’ll likely need to replace your roof before you add solar panels to it. Most solar panels are built to last for 20 to 25 years, and removing them to repair your roof after they’re installed can be a difficult and expensive process. Unless your roof is already new, it will likely need work done on it before it comes time to replace your solar panels. That’s why we recommend ripping the Band-Aid off and replacing your roof now. It may be a bigger ordeal than you were planning to embark on, but in the long run, you’ll be thankful you did.

Get the Help of an Expert

If you try to replace your roof and add solar panels on your own, you’ll just end up in a world of hurt. This kind of roofing work is well beyond the skill set of even the handiest homeowners, so call in professionals such as Interstate Roofing before you try to do anything on your own. It’s not just the extra helping hands you need either. What you really need is their expertise.

Not all roof damage is visible at a glance, so having someone who has the experience needed to spot any problems the untrained eye might miss will be invaluable. Have a conversation with your contractor about what you’re planning to do, and they’ll be able to assess what roofing work might be necessary to make your dreams a reality. Together with their help, you can devise a plan of action for how best to proceed.

Assess the Layout of Your Roof

First and foremost, you’ll need to take stock of what you’re working with. Measure the dimensions of your roof to get an idea of how to best situate the solar array. Take a look at the environment around you and determine if anything might block light from reaching the array. You don’t want to go through the trouble of installing solar panels only to have a tree branch or your neighbor’s house stop the sunlight from reaching them.

Do what you can to mitigate any shade, trimming branches if you need to. Check to see if there are any vents, antennas, or other protrusions that might need to be moved and make plans to adjust their positions. Keep in mind that if you need to move anything connected to your HVAC or plumbing system, you may need to get in touch with a contractor to relocate it.

Start Any Necessary Repairs

Removing a solar array to repair a roof can be a pain, so it’s best to take care of any problems sooner rather than later. After you and your expert help have taken the time to analyze the situation, determine what might need to be addressed before you replace your roof and install solar panels. If you find any weak spots or damaged sections of the roof, they will need to be repaired before even attempting installation. This goes for not just problems on the exterior of the roof, but for under it as well. Water damage, leaks, or damaged rafters will also pose a problem.

A single solar panel is heavy enough, but an entire array will add a massive amount of extra weight for your roof to support. That’s why we strongly recommend you replace your roof before you install solar panels. By taking the time to replace everything first, you can be sure to address any problems now, as well as steeply reduce the odds that you’ll need to remove the array for any future repairs.

How Will You Connect to the Grid?

Unless you’re planning to replace the roof and add solar panels to a cabin out in the middle of nowhere, you’re going to need to figure out how your new array will connect to the grid. Get in touch with your utility provider and see what they’ll need from you to smoothly integrate the solar panels into your home. Are there any fees required as part of the setup? How long will it take and involved is it to get the array connected? How will you be compensated for the energy you generate, and how often?

The financial question will likely be the trickiest, as different states set different reimbursement rates depending on their outlook on solar energy. In states where the reimbursement rate is lower, you’ll need more time to see a return on investment. Everyone’s situation is unique, so take the time you need to sort out the details.

Set Yourself a New Maintenance Schedule

Once you’ve taken the time to replace your roof and add solar panels, you can’t just let them sit up there for the next few decades. As with many aspects of home care, regular maintenance is key to keeping your solar array firing on all cylinders. You’ll still have all the standard roof maintenance, of course. Unfortunately, adding a solar array can make what would be standard roof repairs quite tricky. Again, this is why we highly recommend you have your roof redone before installation.

Then set up a regular inspection with a trusted roofing company, if you don’t already have one, so that you can regularly have expert eyes to spot problems early and nip them in the bud. Solar panels can make it harder to properly drain and ventilate your roof, with the array catching and collecting debris that would ordinarily slide off your roof, so staying on top of any blockages that form is crucial. For the same reason, you’ll want to keep an eye out for any critters that might use your solar panels as a shelter. With frequent inspections, you can stay one step ahead of damages, blockages, and unwelcome neighbors, leaving you to enjoy your green energy for years to come.


5 Minor Roof Repair Jobs You Can DIY and When to Ask for Help

If your roof is in need of major repairs, then you’ll need to be on the phone with a professional contractor ASAP. The last thing you want is for your roof to be compromised or for an already precarious situation to become worse. Often, however, you can actually undertake minor roof repair jobs on your own. Telling the difference between a job you can DIY and one you should leave to the professionals, however, can be challenging.

Below, we’ll illustrate five minor roof repair jobs you can perform on your own, provided you have the right tools and the motivation to get it done. We’ll also explain when it’s time to call a professional and how to find the right people for the job.

1. Fix a Leak from the Inside

Part of the reason you hire a professional roofer is that they’re highly experienced moving around on rooftops. Trying to perform roof work yourself comes with an obvious safety hazard, especially if you’re not used to working high up. The first step, of course, is to locate the leak inside your attic. Finding the source of the leak isn’t always easy; you may need to hose your roof down with water first. Then head into the attic and see if you can see where the water is dripping from. Tell-tale indicators that may help you to do this include nearby water damage and spots of black mold in the wood.

Once you have located the source of the leak, you can put a tarp on it. Smearing tar on your roof may stop the water for a bit, but think twice, as it’s not compatible with many slow slope membranes and will ruin roofing shingles, not to mention void any sort of warranty you may have. Note, however, that these fixes are most likely temporary. If you notice the leak returning, contact your professional roofing contractor.

2. Fill in Insulation

Insulation is a critical part of your home, having a direct effect on your energy bill, as it helps to keep cold air out during winter and hot air out during the summer. Poor insulation is a major part of excessive energy costs, but you can often DIY a solution yourself with a little spray foam insulation. This can be purchased at any hardware store and used to fill in cracks and small holes. Do so, and after a while, your home will become noticeably more comfortable. Just be sure not to fill in any intake vents. Filling holes that are meant to bring fresh air into the attic can cause condensation and mold.

3. Repair Damaged Shingles

The shingles on your roof serve to keep the rain and snow from getting into your house. The weather, however, can also do a number on those shingles. Often, you’ll discover they have been damaged or even carried off completely after a storm with heavy winds. Fortunately, repairing damaged shingles is one of those minor roof repair jobs that you can undertake yourself, assuming that the damage hasn’t become too severe.

Since repairing shingles involves actually climbing onto the roof, you will need to ensure that safety is your primary concern. This means rubber-soled shoes with excellent tread, a good, sturdy ladder, a roofing harness, and at least one other person to serve as your spotter/assistant during the job.

Shingles that have been partially ripped off can be repaired with a little roofing cement, temporarily. Those that are completely missing will need to be replaced. If you do have to replace any shingles, make sure that the new ones you purchase are the correct color and material.

4. Roof Flashing Repair

The thin metal that is used to divert water away from sensitive areas of your roof is known as flashing. Over time, flashing can become damaged or corroded, which can lead to water getting into places where it isn’t supposed to. This, of course, can eventually lead to more serious problems with your roof. Fortunately, it’s relatively easy to make minor repairs to your roof flashing.

Once again, of course, make sure that safety is your primary consideration when repairing roof flashing. If you notice that there are damaged or rusted patches in your roof flashing, they can be patched fairly easily with the same roofing cement that you use for your shingles. First, sand away the rusted parts, and then cover the resulting hole with a small amount of cement. If the hole is too large to simply be filled in with cement, you can also utilize a patch made from the same material as the flashing itself. The patch can be glued over the damaged area using the roofing cement. Again, this is a temporary solution, not to mention unattractive.

5. Quick Temporary Repairs

Sometimes, you will need to perform an emergency roofing repair yourself, just as a temporary fix until your roofer arrives. For example, if a storm tears through your area, it might end up shredding a number of the roofs in your neighborhood, leaving the local contractors busy. It may also leave your roof damaged and leaking in multiple areas. If this is the case, you can usually DIY a quick fix, although you’ll still need to get a professional in there as soon as possible.

Note that you should never climb onto your roof while conditions are unsafe. The weather should be good, and the roof should be completely dry. If there is any rain or wind, or if it’s a particularly hot day, you will have to wait; otherwise, the situation may be unsafe. When it is safe, however, you can create a quick and temporary fix by spreading a waterproof tarp across the damaged area of your roof and quickly nailing it down with a few roofing nails and lath.

It’s also possible to purchase roofing tape to quickly plug holes in the roof if you have a low-slope roof. This can be found at most hardware stores, although, of course, it is also a very temporary fix.

When To Ask For Help

Anytime the damage has become more severe than a simple patch job can fix, or when the job seems like it may be unsafe for you to perform on your own, you should contact a professional roofer. Remember that doing the job incorrectly can lead to extremely costly repairs down the road, so it’s critical that it’s done right. If you’re uncertain about whether you can DIY the job, it’s better not to take the chance. Contact a professional.

Finding the right professional is a matter of shopping around. Look for someone who is properly insured and certified and who has many years of experience. Interstate Roofing is a great example of such a company. Having been in business since 1988, you can be confident that we will keep your roof in tip-top condition for many years to come.

Spring Is the Perfect Time for Interstate Roofing Maintenance

Why Spring?

As the warm weather approaches and we can finally get outside again, your roof maintenance may be the last thing you want to be thinking about. In reality, spring is the perfect time to get it handled before the rush of summer activities. The winter months take a hefty toll on a roof, whether it’s heavy rains, freezing temperatures, ice, or snow, they all have the potential to cause serious and costly damage.

Getting your roof assessed and repaired early and regularly will take a load of stress off you when the glory of summer is fading out and time starts running short before the rains arrive. As summer sets in, you might discover it can be challenging to find an available professional, or you may have a very long wait. When it comes to the roof over your head, it’s better to be proactive and contact Interstate Roofing for an inspection and repair assessment.

Why Choose a Professional?

There are myriad reasons for hiring a professional to inspect your roof. Superior knowledge and experience mean they have the ability to identify issues that a layperson just might not recognize as a problem. They are skilled at identifying peripheral problems, such as issues with a gutter system, chimney, or structural support, and a professional will have all the necessary and appropriate safety equipment and protocols for repairs. Probably the most obvious safety aspect of working on a roof is the fall potential, and if you have a multi-level roofing situation, this could mean a substantial distance to the ground.

Most homeowners aren’t really DYI roofers, and for good reason. Roofing may seem straightforward on the surface, but there is a tremendous amount of knowledge and expertise that may mean the difference between a roof that lasts the life span of the manufacturer’s estimate, or one that fails, potentially causing water damage to the interior. A professional will know what and where to look to ensure that your roof is working as it should. Even a small leak can cause thousands of dollars in water damage, wood rot, mold, or more.

If you’re a strict do-it-yourselfer, you’ll need some additional information on roofing problems to look for when performing your own roof inspection. Most importantly, if you have an emergency, a prepared professional is going to get that handled effectively and efficiently. Luckily, the Interstate maintenance team is on-call 24/7 for those urgent situations.

What Is Interstate Roofing Maintenance?

Experts recommend having annual roof inspections to evaluate the condition of your roofing materials. Each year, your home is subjected to rain, snow, ice, hail, and wind, and sometimes it can happen all in the same day, so it isn’t surprising to have seasonal physical damage, moss or algae growth, missing vent covers, or improper guttering, each of which can affect the life of your roof. Also, your roofing materials manufacturer may have specific maintenance guidelines that must be followed in order to keep your product warranty in good standing, so make sure you get those details from your roofer.

In general, annual roofing maintenance includes a visual assessment of the roof and then getting any missing or damaged shingles replaced immediately. As mentioned earlier, an experienced professional from Interstate Roofing could also identify less noticeable issues, such as missing granules, curling, cracking, and lifted flashing.

If you have a chimney, the contractor will notify you of any cracked or loose bricks that should be replaced, of loose or cracked mortar that should be addressed, and of any flashing issues. A falling brick or chunk of your chimney can require additional, costly repair.

After the exterior inspection, a professional roofer may also look at your attic. This isn’t common with a standard roof maintenance contract but can be done when issues are identified. Additionally, water stains on the ceilings, bulging or bubbled paint, and mold or mildew are signs that there’s a leak that must be addressed. Finally, your inspector can make recommendations relating to tree branches that may hang over your roof creating problematic shady areas or areas where a branch has the potential to cause friction wear and tear if it can connect with your roof during windy weather.

Roof Cleaning

Once the required repairs have been completed, it’s time for the clean routine. It’s not advisable to have your roof washed each year. If regular maintenance is performed (keeping the roof free of dirt, debris, and moss), you should never have to wash your roof. If a roof isn’t regularly maintained, sometimes the only thing left to do is to remove the moss by pressure washing. “Wash your roof” may not be something that even occurs to you, and for most people, it’s just too risky or physically challenging to be working on a roof. Not to mention, a power washing turned up too high can damage the roof more significantly than the moss you’re trying to get off. Our team of experienced professionals has the proper safety equipment, tools, and techniques to get the job done in the safest way.

A thorough roof washing will include removing all leaves and debris, clearing the gutters and tops of spouts, rinsing the shingles, installing a pesticide (in some cases), and providing recommendations to maximize your roof’s performance. It’s also a good idea to water and protect your landscaping before your roof maintenance begins.

Interstate Roofing maintenance includes gutter cleaning for a very simple reason: a poorly functioning gutter can introduce pathways for water to seep into your structure and ultimately cost you time and money. Your professional roofing maintenance should include checking that the gutter is properly secure, appropriately sloped, clear of any debris that might prevent drainage, and free of rust or cracks.

Maintenance Costs Less than Damage Repair

Roofing maintenance isn’t something to take lightly. Roof maintenance could cost as little as $400. if neglected, small damages can cause big problems in the long run, and replacing an entire roof can cost you $10,000 to $50,000, plus. This is a pretty good incentive to start early and recognize that roof maintenance isn’t a job for a neighborhood college student home on spring break with a power washer. Incidentally, this can cause more damage than good, so take the time to develop a relationship with a roofing expert you can trust.

Interstate Roofing has 30 years of experience in Oregon, and we have a dedicated crew to deliver the high-quality roofing options our clients deserve. Most roofs last about 20 years in the Pacific Northwest. so keeping it in optimal shape is in every property owner’s best interest. Contact Interstate Roofing to schedule your professional maintenance today.

5 Signs You Need Roof Repair in Vancouver WA

The roof is one of the most important parts of your entire home. However, even with how essential the roof is, it can be commonplace to miss key signs that roof repair in Vancouver, WA, is necessary. No matter how strong your roof is, it’s still going to have a limited shelf life. Even a strong roof built out of asphalt shingles is going to need to be replaced after around 20 years or so. So regardless of what your roof is made of, it’s crucial that you keep a close eye on its condition because if that roof is badly damaged, that could easily result in major damage to your home.

It’s not always 100 percent clear when you need roof repair, but there are some definite tell-tale signs you can look for so you’re aware as early as possible that action needs to be taken. When you spot these signs, you should hire roofing professionals such as Interstate Roofing to take care of your roofing needs.

Whichever company you select, you should make sure beforehand they fit the bill for what you require in terms of experience, reputation, location, and pricing. Don’t be afraid to be picky, as this is an extremely important job, so it must be done correctly, efficiently, and cost-effectively. Picking the wrong roofing company isn’t an option because if the job is done by somebody who can’t adequately complete it, you could be looking at damage to the home that’s not only gravely serious but completely irreversible as well.

Here are five signs you should be able to spot without much problem that would indicate a need for quick roof repair in Vancouver, WA.

1. Too Much Moisture or Too Many Leaks

Moisture doesn’t generally just appear out of nowhere. Rather, it tends to be a condition that permeates as the result of a damaged roof. In addition to obvious leaks, the presence of water stains can be a way of determining whether serious damage has either already occurred or is on the verge of occurring soon.

If this is what you’re facing, you need to deal with it immediately because it can not only lead to expensive long-term property damage, but it can also result in widespread mold in your home, which could be a detriment to the health of your family.

2. Sagging Roof Deck

A sagging roof deck isn’t usually an event that happens overnight but, instead, is something that develops over a significant period. The easiest way to detect this is to see if the natural lines on your roof look warped or are simply sagging.

Most roofs have a natural angle, but they should also have a consistently straight line. If you see that your roof doesn’t have this, you should replace your roof as quickly as possible because it almost certainly means your current roof has reached the end of its life span. You cannot afford to ignore this issue under any circumstances because, if you do, it could potentially lead to your entire roof collapsing.

3. Major Damage to the Shingles

Shingle damage is generally the most obvious sign of roof damage, and as a result, it should be easy to spot. If you see missing shingles, shingles with curled edges, or cracked shingles, you know your roof is in trouble, and you need to call roofing professionals. You may also see asphalt shingles that have shed granules. An easy way to see if granules have been shed is to look for black sand—which is what granules look like—in your gutters or around the outside of the house. This is a surefire sign that your shingles are in desperate need of replacement.

If it’s only a few shingles that must be replaced, you may be able to patch or repair them. However, if multiple shingles need replacement, you should replace the entire roof. Either way, these repairs should be taken care of immediately because the longer you wait, the more the damage can spread.

4. Algae Growth

Algae may be something you sometimes would like to see in the ocean, but it’s not something you ever want to see on your roof, unless you have invested in green technology on your roof. So if you haven’t taken the initiative of creating a green roof, then you don’t want to see the shingles on your roof covered in algae. That’s a clear indication your roof needs repair in Vancouver, WA.

Algae/moss growth on your roof may be the result of moisture building up within certain sections of the roof. It can be the byproduct of a sagging roof, damaged shingles, or tree cover and Pacific Northwest weather. So if you spot algae or moss growth of this nature, it’s a good reason to call roofing professionals as soon as possible.

5. Clogged Gutters

If your gutters are clogged almost routinely, there’s a high probability that you’re dealing with serious shingle damage. Frequently clogged gutters are considered one of the most obvious warning signs that your roof needs major repair if not a complete replacement.

So, if you see a clogged gutter, go in for a closer look to see what may be causing the issue. If you see numerous pieces of shingles or granules, then your roof is rapidly deteriorating and needs to be replaced immediately. You cannot afford to wait very long to replace the roof because until your roof is fixed, your home is highly susceptible to adverse weather conditions, such as heavy rain, which could cause costly and painful long-term damage to the house.

If you need a second opinion, call in professionals. A quality roofing company like Interstate Roofing will be able to look over the issue and give their honest opinion and a free estimate for any work that needs to be completed.

Summer Is the Perfect Time for Roof Repair in Portland: Do You Need It?

What does it mean when the weather turns beautiful, the kids are out of school, and the smell of barbeque is wafting down the street? It must be summertime in the Pacific Northwest—and that means it’s also the perfect time to consider repairing your roof. In fact, you may have already Googled “roof repair Portland, Oregon,” recently because you’ve started thinking about whether or not your roof might need some TLC.

The warm-weather months are the ideal time to get serious about these types of improvement projects, so let’s look at some of the factors that might determine whether you need to repair your roof.

The Importance of Roof Inspections

Your roof protects your home and everything inside of it from rain, sun, snow, and wind, so it’s especially important to maintain and keep it in good working condition. Because your roof is a complex structure that’s exposed to nature’s elements every single day of the year, there are numerous issues that can come up. And when it comes to your home, an ounce of prevention is most definitely worth a pound of cure. Or, in other words, regular maintenance is good for both the appearance of your home and your wallet. Dealing with any needed repairs sooner rather than later will end up saving you money in the long run.

Roof damage can be obvious, like the quintessential drip-drip of water into a bucket due to a leaky roof, or noticing damaged or peeling shingles. It can also be subtle, so you’ll need to be on the lookout to be able to recognize the signs of damage. This could mean doing an inspection of the roof anytime there’s extreme weather or if your roof is getting old. Even if your roof is on the newer side and the weather has been fair, it’s still a good idea to pay attention and prevent any minor problems from becoming bigger. When inspecting the roof, remember to look at the exterior and the interior. Roof damage can happen anywhere.

Specific Signs to Look For

When checking the outside of the roof, there are a few warning signs that indicate a need for repairs. The first is the visible presence of discoloration and water spots, which are small areas of water damage that will eventually warp shingles and the exterior finish. It’s especially important to pay attention to where the roof and the exterior walls meet. Damage can certainly create visible distortion in this transition area, so you should be able to detect any signs of a problem.

Similarly, make sure to check around the chimney, vent pipes, skylights, and other objects that are in contact with your roof, as these areas are subject to wear first. Visible signs of wear to shingles or damaged flashing should be taken care of immediately, and usually minor roof repairs will fix the situation. Either way, it’s best to have these areas looked at by a professional as soon as possible to avoid leaks.

While inspecting your roof, make sure to also look at the gutters. One sign of a damaged roof is the presence of small granules resembling black sand clogging up the gutters. These granules likely come from shingles that are either damaged or have been exposed to the elements for too long, and it’s a good indication that you should also look at the shingles themselves. They might be breaking down due to weather or the lack of proper ventilation from the inside. Are the shingles curled at the ends? If they are cracked or curling, it means they’re nearing the end of their lifespan. Missing shingles also mean you need roof repairs, because they should be replaced as soon as possible.

To monitor roof damage that’s happening on the inside, make sure to pay attention to the attic space and rooms closest to the top of the house. If there is significant water damage, it will begin to warp the ceiling and walls of the rooms below. You might notice small—or large—spots of brown staining on the ceiling or on the insulation in the attic. Homes with hardwood floors may also start to see drops or puddles of water in the middle of the room. If you notice the decking or rafters in your attic are sagging downward instead of remaining straight, they may be wet from leaking moisture; this can usually be managed with repairs if the issue is localized.

Another thing to look for while checking the interior is outdoor debris inside of your home, as this can mean there’s a hole somewhere in the roof. Speaking of holes, if you can see any streams of light coming into the attic or any other room underneath the roof, it’s an opening that could also let water in. This is usually a sign that your roof needs immediate repair so as to avoid additional damage to both the interior and exterior of your home.

I Need Roof Repair! Now What?

If you’ve discovered that roof repair in Portland is something you’ll be searching for due to coming across any of the above warning signs, pause for a moment and congratulate yourself for being a responsible homeowner who is staying on top of their roof repairs (no pun intended).

Next, consult with a seasoned professional such as Interstate Roofing that can help you take care of the issue, sooner rather than later. Remember that summer is the perfect time for roof repairs in Portland, so you’ve picked the right time to do it. You can ensure your home will be protected from the elements once the autumn and winter weather returns.

5 Facts About Professional Roof Maintenance in Vancouver WA

There’s no doubt about it: the roof is one of the most important parts of any building. It keeps out rain and snow and protects people and property from the sun on hot days. All too many people, however, neglect the maintenance of their roofs and allow them to fall into disrepair.

Other people attempt to DIY roofing projects, and while there are certain tasks you can undertake yourself, ultimately, roof maintenance is something that should be undertaken by a professional. While home and business owners tend to worry about the costs involved in hiring a professional roofer, the reality is that the cost to you will likely be far more if you neglect professional maintenance. Here are five facts about professional roof maintenance in Vancouver, Washington.

The Best Roofs Are Built with the Vancouver Climate in Mind

Does it sometimes seem like your roof needs more maintenance than those of other nearby homes? There might be several reasons for this, but one of them is critical: climate.

Have you ever wondered why the buildings you see in the deserts of Utah, Arizona, New Mexico, and other arid climates have such a distinct look to them? The famous pink adobe buildings and flat rooftops; compare that to the equally iconic pointed gables snowy places like Switzerland are known for. The fact is, those picturesque roofs were designed with the climate in mind.

If your building is being constructed in a hot, dry area with minimal rain, a flat roof will often be your best option. It will save on materials costs and you usually won’t have to worry about water pooling up there. On the other hand, if you live in an area known for getting lots of rain and snow, your roof will likely need a steep incline so that puddles of standing water don’t form and damage it.

The Pacific Northwest, and specifically coastal areas like Vancouver, tend to get a lot of rain throughout the course of the year. Because of this, if your roof is too flat, you’ll notice your roof repair bills go way up. Talk to your professional roofer about ensuring your roof is optimized for the Vancouver climate.

Roofs Don’t Last Forever

Plenty of people spend a great deal of time and money fussing about their porches, bedrooms, or other parts of their homes without stopping to consider their roofs. But depending on when you moved in and how long your house existed before you showed up, it’s possible that the roof is the oldest part of your home. Even if it isn’t, you have to consider that the roof, just like every other part of the home, won’t last forever. Indeed, your roof is one of the parts of your home that receives the most wear and tear, as it’s constantly subjected to the elements. Even so, a well-cared-for roof can last for decades. With proper care, your roof can last for 25 to 30 years or more.

The key to the longevity of your roof is, no surprise, maintenance. You’ll need to have your roof checked out and repaired on a semi-regular basis, with a trusted professional roofer who will look for leaks and other problems and repair them. If your roof is nearing the end of its useful life, the same roofing professional can start the process of replacing it.

Your Roof Is a Huge Part of Your Home’s Value

People often hesitate to have their roofs repaired when they should because they’re worried about the upfront costs. While it’s true a major roofing project can set you back a decent amount of money, ultimately, keeping your roof in good shape will save you a lot more in the long run. And should you ever sell your house, an immaculately cared for roof can actually earn you money. This is because the roof is such a major part of your home’s value. When a house hits the market, prospective buyers will want to know that, should they choose to live in the house, that it’s protected from the elements and they won’t have to undertake any major repair projects for a good, long time.

The appearance of the roof also contributes in no small way to a home’s curb appeal; in other words, the better your roof looks, the more valuable your home is. Regular roof maintenance will go a long way toward boosting the resale value of any house.

Your Roof Can Save You Money in Other Ways

With today’s green movement in full swing, homeowners are always looking for ways to conserve energy, while also saving money on their energy bills. Talk to your professional roofer about possibly constructing a “green” roof: one that’s designed to keep your home warmer in the winter and cooler in the summer. Modern technology has given us roofing shingles that are lightweight, durable, and can reflect a good deal of the sun’s rays away from your home.

Your home, especially if it’s older, might be equipped with an obsolete roof. Talk to your roofing professional about beginning the installation process for a green roof, and you’ll save money on energy, increase your home’s value, and possibly even earn Vancouver tax credits.

What Services Are Available with Roof Repair in Tigard, Oregon?

It starts with a windstorm. A few days later, you notice water stains in your ceiling that weren’t there before, puddles of water in places there shouldn’t be, or a feeling of more moisture than usual inside your home. You put it off, thinking it might be your imagination, until … oh no … is that mold?

But part of the confusion and potential stress of roof repair or even replacement is not knowing what tools or options are available to you. There are many other ways to keep your roof in good shape, even if the above doesn’t apply. That’s where Interstate Roofing comes in!

Interstate Roofing is a family-run business, and has been going strong since 1988. Roof repair in Tigard, Oregon, can often seem like a daunting or expensive project to tackle. Before you start thinking the situation is desperate, here are four ways Interstate Roofing is available to help you.

Roof Repairs

If you know that you have a leak and have a good idea of where it is or what caused it, Interstate Roofing is on call 24 hours a day, 365 days a year. Maybe that windstorm did hit after all, or an overhanging tree limb wore away a few tiles and the protective layer underneath. Reach out to us or visit our website for further information and to talk with a service technician specifically trained to find and repair leaks (note that emergency rates will apply).

With any repairs anticipated to be “minor repairs,” the technician will come to your home to find and repair the leak on a time and materials basis. However, if the leak is actually part of a larger repair or project that will exceed “minor,” the technician will cover up the area with a tarp or make a temporary repair to prevent further water damage. After that, you’ll receive a quote for a permanent repair or a replacement roof.


Dry rot is a big problem in the Pacific Northwest. Despite its name, dry rot requires dampness for fungi to thrive and to eat away at timber and other construction materials. Dry rot, also more aptly called brown rot, will break down the cellulose in wooden materials, leaving the wood weakened and brittle. It may also look different, giving the wood a shrunken appearance, and in extreme cases will crumble easily.

But don’t despair! Interstate Roofing has a team of in-house carpenters who can help in case there are any unforeseen dry rot or structural issues they discover while fixing your leak. This means there won’t be any waiting around for subcontractors to show up, no third party giving another bid. This speeds up the process so that your home can be repaired quickly, without any lag.

Additionally, our carpenters can help you realize your home’s full potential, with installations that include skylights, solar tubes, fascia boards, and more!

Maintenance and Cleaning

We fully believe at Interstate that caring for your roof through maintenance will give it a longer life and give you greater peace of mind throughout that life. We offer maintenance agreements specially designed to ease our customers’ worries and to hopefully prevent those panicked calls in the middle of the night.

Through regular visits, we can ensure to meet (and exceed!) standards of both the industry and our own, making sure your roof looks its best for as long as possible and prolonging its life. Of course, if the roof does leak even after regular maintenance—because these things do happen—having regularly visited your roof will mean that your roof will be familiar to us as well, and we won’t be starting from square one.

Another thing to watch for is whether you see moss growing on your roof. It may lend a certain charming air to it, but that plant matter is breaking down the elements in your roofing tile and may create more problems than you realize. Moss begins growing when spores are released into the air and land on your roof.

Over time, the moss will anchor into the roof shingles and grow into the corners between shingles, where spores tend to collect. In the Pacific Northwest, where we get lots of moisture year-round, this means the moss can grow into a mat that will start to pull the shingles apart. North-facing and shaded roofs will see a higher rate of growth since they won’t get as much sunshine and won’t dry out completely.

Once it’s established, the moss can even act like a sponge, which means the water really won’t go away. The moss will store rainwater this way, and that could create a wick effect where that water will soak into the roof underlayment, which may eventually mean not repairs, but replacement. Regular maintenance and cleaning of moss, lichen, or algae will ensure that you won’t need roof repairs, which could be much more expensive!


Gutters are another aspect of a roof that needs regular maintenance. They require occasional patrolling, especially if you have large trees nearby that shed their leaves every year. Clogged gutters can’t do their job! Gutters protect not only your roof, but also the foundations of your home, preventing your basement from flooding, keeping your siding and exterior paint dry, and stopping water seepage into windows and doors.

Directing water away from the building—especially in Oregon where we get a few months of heavy rains and some months of light rain every year—becomes very important. Interstate Roofing can offer gutters in a variety of colors, materials, sizes, and styles. Any style of gutter offered by Interstate technicians are proven systems and can be custom fabricated to best suit your home and what look you want to create. We can also add accessories, such as cleanouts, which make it easier to unclog and harder to clog in the first place. For more information, download Interstate’s Gutter Guide Free PDF.
