5 Signs It’s Time for Flat Roof Replacement

A flat roof is exactly what it sounds like: a roof that has very little slope to it. Usually, this style of roofing is used primarily in commercial applications, especially in the Pacific Northwest. You’ll find more residential flat roofs in parts of the country that are arid because one of the drawbacks to having a flat roof is that it can be difficult to find and repair leaks. With our consistent precipitation, no one wants to deal with that in their home.

The benefit of having a flat roof is that you can also use it for additional space. For instance, green roofs or eco-roofs are popular places to have small gardens where a roof is visible to inhabitants of the building or those around it. In urban places, such as downtown Portland, apartment buildings, colleges, and medical complexes are creating green spaces on the roofs visible to their students, patients, and occupants. This way, architects are also creating spaces for stormwater management, reducing the urban heat island effect—where cities have a higher ambient temperature due to so much concrete—and also creating spaces for pollinators such as bees and hummingbirds to live.

So, if you have a flat roof, how do you know when it’s time to perform some maintenance or replace it? Here are five signs it’s time for flat roof replacement:

1. Cracks in the Flashing

Anywhere there is a sharp bend on your roof—any 90-degree angle—there will be flashing, which seals water away from the interior of your building. Think of flashing as the seams of your roof. If your flashing is cracked and old, water has a natural pathway into your building. Needless to say, it can cause a lot of damage to the wooden joists under your roof, the support beams, and any insulation that might be there. You can bet that if you can find old and worn-out-looking flashing, other parts that you can’t see will need to be replaced too.

2. Blisters Forming

You’ll see this more commonly in a flat roof that has membrane roofing. Blisters or bubbles form when pockets of air or moisture are trapped between the layers of the membranes and can be exacerbated by regular foot traffic. Sometimes, they are a result of a crack in the seam, which then collects moisture or cold air from below.

If you catch a blister before it cracks, you can sometimes repair the roof instead of replacing it. However, if it’s a consistent problem, or the blisters or bubbles show up all at once all across the roof, it’s probably time to consider replacing it. Even if you’re able to repair one blister, there’s a good chance it will come back again and again.

3. Water Is Pooling

This is actually the biggest and most common problem with flat roofs, especially here in the Pacific Northwest. Since we live in a wet climate, you want to be sure that there are no places on your roof where water will “pond” or pool and have appropriate drainage. If you have a space where there is a consistent pool (and if your roof is fairly new), you can install additional roof drains or a tapered system. Of course, if you are maintaining an old roof rather than fixing a new one, you may have bigger problems. The faster you get the water off the roof, the better the chance you won’t spring a leak.

4. Building Materials That Hide Damage

You may think this is a good thing at first, but if the damage is hidden, it may not occur to you to repair or replace the roof until it’s too late. If you have a tar and gravel roof—which is becoming less and less popular for this reason—it may be difficult to actually find the damage, and even an experienced contractor may only have a 50-50 chance of finding the leak. If it’s time to replace the roof anyway, make sure the flat roof replacement material is something that is easy to work with and shows damage instead of hiding it.

There are many types of flat roof coverings, including asphalt, synthetic rubbers, liquid membranes, and glass-reinforced plastic. They all have advantages and disadvantages, so make sure you ask your highly experienced technicians at Interstate Roofing which one is right for your building and your budget.

5. Alligatoring

Have you ever seen the pattern in an alligator’s skin? You’ll see similar patterns in the cracks that can form in your roofing material. As the sun’s UV rays dry out the top layer of your roof, you’ll be able to see this kind of damage. Remember, while it’s frequently cloudy in our climate, some UV rays will still get through and slowly degrade your roofing material. Clouds only block some rays—not all of them. If you don’t handle this problem, these cracks can let in ice and water, and the heating and cooling cycles will make these cracks wider and lead to more and more problems.

But if you replace your roof, or if you apply a new coat to the roof when you first notice these patterns, you can say, “See you later, alligator!” to this particular problem. If you have noticed alligatoring in the past, or if you’ve recently replaced your flat roof, it’s good practice to inspect your roof every six months or so and after major storms, including ice and wind storms.

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.

5 Reasons to Use a Local Roofing Company in Portland

Finding a Portland roofing company to replace or fix your roof can be quite a chore. Any major changes are bound to be very expensive, so you need to make sure you hire a Portland roofing company like Interstate Roofing that can get the job done the way you want it. Hiring a Portland roofing company is always preferable because by bringing in a local contractor, you’re ensuring yourself of multiple unique advantages in the process. And, of course, by finding the very best Portland roofing company for your needs, you’re not only doing what you must to protect multiple essential functions of your home, but you are also taking the proper precautions that will keep your home in tip-top shape.

So why hire locally?

1. Knowledge of the Area

If you hire a Portland roofing company, they’re already experts on local rules and regulations, which saves time, money, and energy that an outside contractor would need to use to find these things out. They are aware of exactly how to comply with city, state, and town codes and have the proper permits to do the job without being delayed by red tape a non-local contractor may not know about.

They also understand local weather conditions and how they can affect the type of roofing work you need done. For example, somebody in the northeast would be best served by a strong asphalt roof that can help protect against snow, rain, and brutally cold weather. The asphalt is powerful enough to keep the snow from caving in the roof, which is something you would want in a place like New York but would be an unnecessary expense somewhere like Florida or Arizona.

2. Quick Response and Availability

When you’re choosing a Portland roofing company, it’s only natural that you’re going to have plenty of questions. A local roofing company can more quickly respond to your inquiries and even send somebody directly to your home to answer them if necessary.
Also, if an emergency occurs, a local roofing contractor is in a position to serve your needs right away. As an example, if you live in California and an earthquake destroys your roof, a company located nearby can be on the scene to help rebuild that roof much faster than one that’s not located nearby. And they’ll have previous experience working with homes with earthquake damage, better preparing them for your job. Having your roofing company be local can give you enormous peace of mind, especially during seasons that produce horrible weather conditions.

3. Greater Accountability

By hiring a local roofing company, there’s a much greater chance your warranty will be backed up and your problem fixed because the company cannot run and hide the way they might be able to if they were out-of-towners. Additionally, most roofing companies offer a full warranty that covers labor and material issues. This means that should an issue occur with the original installation, you always have an easy solution nearby.

4. Local Experience

A local roofing company that has existed in your community for many years will have built an extensive network of resources, including material suppliers as well as other tradesmen, such as electricians and plumbers. This can help the company get favorable rates on needed goods and services, which would lower their overhead and create savings that can be passed on to you. Not to mention the fact that they could help with rates if you need separate work done by these tradesmen, and the roofing company could provide a network of valuable referrals to you that would provide you with trustworthy companies to handle other necessary work within your home.

Plus, a local roofing company will prioritize your business heavily because they know they can’t afford to get negative word of mouth from customers in the area. Word of mouth is one of the most important business generators for a local company, and having negative words spread about a company all around the local area is something any local contractor would desperately want to avoid so as to not develop a bad reputation. A non-local company may have more flexibility in this area since word from out of town doesn’t travel as well.

In addition, many of the owners and workers live in the local area because the owners and workers live and operate in the local area, they’ll have extra incentive to do an outstanding job because they want their city to be as high caliber as possible. It reflects well on them and their families, who share the community. An out-of-town company won’t have this concern and might see making money as its primary goal.

5. Being Neighborly

Sure, you want to get the best deal and the best company possible when you’re shopping for a contractor to fix or replace your roof, but when you can do that within the local community, there are added benefits. For starters, by giving business to a local contractor, you’re ensuring that your money stays within the local community and continues to help its growth and prosperity.

Second, when you help a local business out, it can mean they’ll help your community in a way that helps you out in return, in addition to simply doing a great job for you. For example, if you own a business in the local community yourself, by hiring a fellow local business, you can develop a relationship that could result in that roofing company hiring your business down the line. And when word gets around about you doing business locally, it could help you generate business from other local merchants or help you develop a positive reputation that could get you favorable rates from other businesses in the area.

What You Need to Know About Attic Insulation in Portland Oregon

Whether you’re trying to beat the heat in the summer or keep warm in the winter, your attic insulation is a critical part of your home climate control. Quality attic insulation is particularly important in Portland, Oregon, due to the fact that the weather can vary so widely over the course of the year. If you’re thinking about putting new insulation in your home or just want to evaluate the insulation you already have, you’ll want to be able to make an informed choice. Here are the basics of what you need to know about attic insulation in Portland, Oregon.

How Insulation Works

Before you jump headfirst into any changes to your insulation, it’s worth knowing what it’s there for in the first place. The answer might seem obvious: it’s there to insulate your home. But how exactly does insulation help maintain the temperature of your home? In the most basic of terms, insulation helps contain the air your HVAC system is heating or cooling and prevents any heat exchange with the outdoor temperature.

In the summer it provides a shield from the relentless heat of the sun, allowing your air conditioner to keep your home cool with less energy. In the winter it prevents warm air from escaping into the attic, stopping you from losing valuable heat to the chilly outdoors. Many beautiful old homes also have drafty attics with poor insulation. If you’re not careful, your attic can make your home a climate control nightmare.

What to Look for in Any Current Insulation

If you already have some attic insulation, you’re ahead of the game. That being said, you need to be able to evaluate what you have to see if it’s still doing its job. Before you decide if you need any work done, take a look at what you already have. All you need to do is determine what material your insulation is made of and how deep it is, and you’ll be able to figure out how resistant to heat flow it is. This rating is known as its R-value.

If any of your attic insulation is moldy, damp, or compressed, it’s just not working anymore. Mold and dampness can indicate a leak in the roof, a serious problem that demands the help of a professional. If your home was built before 1990, take extra care when examining your insulation, as you might be dealing with asbestos. Get the material tested before pulling anything up, and have an expert remove and dispose of it safely.

Know What Materials Work Best for You

There are plenty of different materials available when it comes to attic insulation, but not every material is going to work for each individual home. Insulation can come in a few different forms, such as loose-fill, batt, or spray-foam. They can all be made of various materials, such as mineral wool, fiberglass, or cellulose. Each kind has its own pluses and negatives, so you’ll need to take stock of what you’re working with before committing. When trying to decide what form and material are right for your home, you should consider the target R-value, layout of your attic, and cost.

The Department of Energy recommends different R-values for different climates, so you’ll need to be sure you’re choosing a material that meets the standard for attic insulation in Portland, Oregon. For temperate climates like the Pacific Northwest, you’re shooting for an R-value of R-38. With that in mind, take a look at the actual space of your attic. If the joists are laid out in with standard spacing and there are minimal obstructions, batt insulation will work just fine. For attics with a more irregular layout, you may need to use loose fill to insulate every nook and cranny.

The available space can also affect the R-value of your insulation, as some materials require a certain number of inches of insulation before reaching the desired value. Loose fill requires fewer inches in general than batt to achieve higher R-values, so if you’re working in a cramped and uneven space, you might not have much of a choice.

Finally, that brings us to the cost. Spray-foam insulation is one of the most effective methods of insulation, but it’s also one of the most expensive to install. Batt insulation, by contrast, is much cheaper but requires more material to achieve the same R-value. Once you’ve determined your desired R-value, you can do the math to determine what material and method of insulation makes sense for you.

It Helps You Save on Your Heating Bill

More effective insulation might be more expensive up-front, but did you know it can lead to savings down the road? When you properly seal and insulate your house, the internal temperature becomes more stable. That means your HVAC system won’t be fighting the elements as much, allowing it to maintain your desired temperature with lower energy usage and less wear and tear on the system. That leaves you with a lower heating bill, as well as lower maintenance costs for the HVAC system. Between both, your new insulation can pay for itself.

You Can Get Money Back from the State

The Pacific Northwest is widely known for being an environmentally conscious part of the country. This green mentality is so ingrained in the population that you can even earn cash rebates for improving your household. Homeowners in Portland can receive money back for having attic insulation up to a certain R-value. If you can get your insulation to R-38, you can earn 25 cents per square foot of insulation as a rebate! This includes labor costs and can really take the sting out of paying for new attic insulation. On top of that, you’ll be doing your part to make our world just a bit greener.

Now that you have the basics, you can start thinking about the next steps. If you’re in the market for new insulation, give the Portland insulation experts here at Interstate Roofing a call to learn about all your options. We’ll help find the attic insulation solution that works best for you.

5 Tips for Summer Roof Maintenance in Portland, Oregon

When is the best time to check the roof of your home for potential maintenance items? If you said winter, you’re half right.

Wintertime roof maintenance in Portland, Oregon, means clearing the gutters of leaves and needles that fell from the trees during the fall. It means ensuring puddling water doesn’t build up on your roof and accumulate where it shouldn’t. And that’s important to watch for during the rainy season.

But it’s equally as important to keep an eye on your roof in the hot, dry summer months. Where do you begin?

Perform an Inspection

In order to determine if you have problems with your home’s roof, you have to do a visual inspection of your property on a regular basis so you know if and when things go wrong. You can start by doing this yourself and then call in a pro if you determine something doesn’t look right. Or if you have any questions that may impact the safety of your home.

First, take a look at your home’s gutters and eaves. This is where debris often accumulates. Left over time, it turns into a gunky mess of leaves, dirt, and other debris that can solidify and block water’s path. These blockages are a common place for rodents or other pests to build nests and make their homes.

Next, take a look at your roof’s flashing. These are the metal strips used around chimneys, vents, and other protruding elements coming out of your roof. Over time, these metal pieces can pry loose and move, allowing water to seep through. This is often where leaks start.

Finally, assess the shingles on your roof. Are any loose? Are any missing? If any of your shingles appear to be damaged, there’s a good chance a problem exists beneath the surface too. That’s the first indication a leak might be developing. And if you notice it during the dry summer months, you’re less likely to receive extensive damage inside your home.

Maintain Your Gutters

Now that you’ve looked inside your gutters, it’s time to make cleaning them a regular part of your routine. That’s the best roof maintenance item you can add to your to-do list to keep your Portland, Oregon, home operating at its best.

Have you ever sat inside and watched heavy rain pour beyond your roof, over the top of your gutters, and puddle alongside your home? That’s what happens when your gutters aren’t doing what they’re supposed to do. That means there’s a blockage somewhere in the system. And it’s your job to ensure it’s removed and the puddling stops.

Many things can impact the flow of water through your gutters throughout the year. A severe thunderstorm can loosen gutters and create tiny cracks throughout the gutter system. If a tree branch breaks off, it can crash into your gutters and knock them loose. Even age can wear on the building materials, breaking down wood, metal, and connections over time.

If you own a home, your gutters are the key to maintaining a safe, dry environment throughout. And one of the most common problem areas is the gutters. Watch them. Check them. Inspect them. And if you think you have a problem, even if you aren’t sure, check with a professional, such as Interstate Roofing, before the problem grows.

Maintain Your Trees

Let’s talk about another common problem with Portland, Oregon, homes: big trees. We love our trees. They’re a part of our culture. We protect them with laws and regulations. But when they’re near your homes, they can also be a bit of a problem.

It doesn’t take much of a storm to wreak havoc on a large tree. Broken limbs can sail across your yard. Large limbs can break away and come crashing down. And, of course, there’s just the day-to-day living with your trees, as they drop leaves, needles, flower petals, fruit, seeds, sap … you get the picture. As much as we love our trees, it also can be a bit of a challenge keeping up with daily care.

It can be difficult to assess the health of a tree, especially when it towers over your home. Even if a tree seems healthy, one quick change in the weather can impact your home and create large amounts of damage. If you have a question about a tree’s health, fix the problem before it becomes a bigger issue and causes extensive damage to your roofing system.

Maintain Your Skylights

Many Portland homeowners use skylights to bring light into their homes. And while they are a perfect addition to any home wanting a little more natural light, they can be a major contributor to home maintenance issues.

Check the flashing that runs around your skylights on a regular basis to ensure it hasn’t loosened. You should check it after every major storm too, as small leaks can quickly become big problems.

While the Pacific Northwest doesn’t see hail storms at the same frequency as the Midwest, there are occasional blasts in the summer. If a small, pebble-sized hail hits the right way, it can damage glass. Small divots and cracks can allow water to flow in a way not designed. And that means the water can move throughout your home in a way you might not expect. It’s always a good idea to keep an eye to the sky, especially if there’s been a severe storm.

Check for Mold

Some of your roof maintenance projects don’t occur outside; instead, they require a steadfast eye as you move throughout your home. As you enter each room in your home, look up to the ceiling. Have you noticed discoloration anywhere on your ceiling? Is there a spot that won’t go away? Does it appear darker in a thunderstorm?

This is a telltale sign something could be wrong up in your attic. Your attic can be a breeding ground for mold if not properly cared for. While you should never touch insulation, especially if it’s fiberglass, you may have noticed problem areas if you’ve ever popped up and taken a look around.
Specifically, check for different colors on wooden beams. Look for peaks and valleys in the insulation batting. Look for movement in metal joists and flashing. Notice unusual smells. All can be a sign of a problem with your roof and water seeping in and impacting the rest of your home.

Mold is a dangerous issue. It’s important to deal with it as quickly as possible so it doesn’t impact your home or your family’s health.

If you spot or suspect any problems during your summer roof maintenance of your Portland, Oregon, home, it might be time to schedule a roof repair appointment. At Interstate Roofing, we’ll happily take a look and provide you with a free estimate of any work that needs to be done.

5 Reasons Interstate is the Best Portland Roofing Company

Roofing repair and replacement is serious work. After all, your roof is literally your shelter from the storm. It’s what protects you from inclement weather and environmental elements.
