Avoid These Common Residential Roofing Mistakes

It’s easy to take the roof over our heads for granted—that is, until the roof over our heads needs to be replaced. It’s a big job and can be a good investment, but it can turn into a stress-inducing disaster if the job isn’t done well. You may be able to do the work yourself, but most people will need to seek help from residential roofing experts.

Finding someone who has decades of experience and pride in craftsmanship will help you avoid many of the potential problems that can occur while replacing a roof yourself or with a company that hasn’t had enough experience or training.

Starter Shingles Installed Incorrectly

Starter shingles go under the first row of shingles, and many people doing the job themselves might install these incorrectly or sometimes not at all. The starter shingles act as a barrier since the first row doesn’t have a shingle below it. The starter shingles are vital and protect from water that could invade the sheathing under the bottom shingles, and they’ll provide a straight line to cut shingles on.

Improper Material for the Slope

With a big variance in roof slopes and sometimes having multiple different slopes on one home, choosing a material that will protect the house properly is important. Differently angled slopes have different levels of water run-off. Choosing a material that doesn’t match the slope can leave that part of your roof a weak point and in danger of water damage.

Improper Use of Nails

Repairing a roof takes finesse. If too much pressure is applied, nails will be driven too far in and puncture the shingle mat. This could lead to weaker shingles that are susceptible to being torn off by the wind. If shingles aren’t nailed properly or have too few nails, shingles can slide out of position. There are many different ways to create problems when securing shingles with nails, and poor workmanship could potentially void your roofing warranty.

Insufficient or Improperly Installed Valley Metal

The roof valley is the part of the roof that is most likely to have a leak. This is where the water runoff flows, so the roof valley is hit the hardest with any water from rain or melting snow or ice. Therefore, a roof valley should have an ice and water shield installed, and/or a metal valley. If the metal flashing is either missing or not secured properly, the shield will have to be reinstalled and the roof re-shingled. Not securing material or using enough sealant can cause buckling and water leaks.

Sometimes the valley flashing can be installed incorrectly by amateur contractors or roofers. The flashing needs to be layered under the shingles, not on top of them. The U-shape of the metal should be facing the valley. Otherwise, water runoff might flow in a direction it shouldn’t and cause premature deterioration of the flashing or shingles.

Not Planning for Ice Dams

Not all homeowners need to plan ahead for this, but if you live in a cold climate, you know how much damage ice dams can cause. Without proper insulation, ice forms at the roofline and forces water under the shingles, creating a dam. By putting down an underlayer in the roof starting at the roofline and continuing for at least three feet, you will help add another layer of protection to avoid the damaging effects of melting ice water.

Not Allowing Ceilings or Attics to Vent

Not having adequate venting can cause major damage to your roof and roofing materials. Heat rises and hot air is full of moisture. That moisture causes condensation to build up and, over time, weaken the shingle material prematurely. When laying down shingles for your roof, it’s imperative that they are laid down to allow proper ventilation from your attic or ceilings.

Not Aligning Shingles Correctly

Laying the shingles improperly makes a poor roofing job easy to spot. If the shingles are misaligned, it just looks bad. If the butted joints aren’t on the same horizontal plane or if the cutout on three-tab shingles isn’t vertical, your roof won’t look aesthetically pleasing, and if the shingles have been improperly nailed, there’s potential for roof blow-off.

Incorrect Shingle Overhang

The shingles should overhang the eaves and the rakes by a minimum of an inch to an inch and a half. If drip edge flashing has been installed, then the edge of the shingle should hang over the roof between a half-inch and three-quarters of an inch. Too little overhang can allow water to seep into the fascia boards or into the rake boards. Too much overhang and there is potential for the shingles to blow off in high winds. An experienced roofer will ensure the correct placement of the shingles.

Incorrect Shingle Exposure

Shingle exposure is the uncovered part or exposed part of the shingle from the shingle placed above it. Not only will proper shingle exposure create a beautiful roof, but it will also provide optimal roof protection. There are many problems that can occur when laying shingles. If the shingles are layered too far apart, the exposure will be too wide, and there will be areas of the shingles that are now exposed to the elements that shouldn’t be. If the shingles are laid too close together, it can create an undesirable look and will waste materials. Moisture may also start collecting from water run-off if the shingle exposure is shortened and can also lead to them being blown off in high-speed winds.

5 Services Offered by Portland Roofing Contractors

There are many important questions you should ask and things you should research before choosing your Portland roofing contractors. Some contractors have their specialties, but there are some services that tend to be standard. These services are important to the health, maintenance, and durability of your roof, which will help ensure the protection of your building and everything inside, and curb appeal.

Here are five services that are typically offered by Portland roofing contractors. At Interstate Roofing, we offer all of them.

Residential Roofing

You spend a lot of time in your home, and that’s why roofing contractors understand the importance of being certified in residential roofing. You want someone who knows the ins and outs of the style of your home and the area and climate you are dealing with, and someone with experience working on homes, rather than just commercial roofing. There’s a definite difference.

By offering services in residential roofing, contractors like Interstate Roofing tend to have experience working on a variety of home styles: single-family residences, multifamily complexes, and family estates, for example.

There are a variety of services included in high-quality residential roofing. These might include roof warranties, quality materials, professional customer service, and daily supervision by a superintendent on all job sites while work is in progress.

Commercial Roofing

Just like you wouldn’t want a contractor who specializes only in commercial roofing to work on your home, you don’t want a contractor who specializes solely in residential roofing to do your place of business. That’s why many professional contractors have staff trained in both and offer both services. Like Interstate Roofing, they understand the significance of the difference.

Commercial roofing takes a specialized set of skills. Commercial roofing contractors will be prepared to work on a wide array of buildings, such as warehouses, restaurants, schools, office buildings, churches, retail centers, and medical complexes.

When it comes to roofing on your place of business, it’s also important your contractors understand that the less your business is interrupted during roof repair or installation, the better. The professional ones will.

Roof Repair

Leaks happen. Mother nature happens. A lot of problems can be prevented but not all of them. Because of this, roof repair is important, and it’s an important service that Portland roofing contractors offer. Businesses like Interstate Roofing also offer 24/7 emergency service options that you can request if a problem arises. We understand that these issues don’t always occur at convenient times, which is why we’re here for you.

Whether your need is an emergency or caused by the elements over a long period of time, do your research and make sure you’re choosing a Portland roofing contractor you can trust. Damaged shingles, a persistent leak, or structural damage due to mold, large or small, you want to be confident your problem will be fixed properly.

Roof Maintenance and Cleaning

What’s better than needing roof repairs? Preventing them! One of the best ways you can ensure the need for minimal roof repairs is to have regularly scheduled roof maintenance and cleaning, including clearing out your gutters. These are services offered by many professional roofing businesses.

By having regular maintenance and cleaning, you can be sure problems are spotted right away, rather than not knowing they exist until they escalate into something catastrophic. This will also keep your roof looking it’s best, which adds to the value of your property. And it will save you money in the long run.

Maintenance is vital for every roof, whether residential or commercial and regardless of the material that’s used. You don’t want dirt to build up or mold to grow. You also don’t want a small hole to turn into a big one. Don’t give leaks a chance to happen.

Gutters

Gutters are important to every building, home or commercial. They add beauty (which, as we’ve mentioned, can increase the value) and protect your house or business. Gutters direct water away from the building and foundation and keep it from pooling and potentially causing damage.

It’s important for your gutters to have a slight downhill slope. This ensures they drain properly. Even a slope as little as 1/16 of an inch is sufficient—barely noticeable at all—so don’t worry about aesthetics.

It’s also important to note that gutters don’t come in one-size-fits-all. The type of gutters on your building will depend on a variety of things. Do you prefer aluminum or steel? What size will work best with your roof and building? Which gutters will provide the drainage your building needs?

A professional Portland roofing contractor is going to be able to install gutters that meet all standards and fit your needs and curb appeal.

Additional Services

It’s important to choose a company that offers high-quality residential and commercial roofing services when selecting Portland roofing contractors. Select a contractor that offers the above five services, at the very least. However, many will offer more services.

For instance, Interstate Roofing can add attic insulation to any residential roofing project. Attic insulation will help you save on heating and cooling costs. Your home will also feel more comfortable year-round. If you’re interested in learning more, here are some things you should know about attic insulation in Portland, Oregon.
