When it comes to roofing materials, asphalt shingle roofing is one of the most common and most popular among homeowners. It's popular for good reason, too. Asphalt shingles are easy to install, affordable, and long-lasting. However, that doesn't mean that there aren't some potential issues that can arise. Some of the most common asphalt shingle roofing issues start at installation. Here's a look at why you should always rely on a roofing contractor instead of trying to install an asphalt shingle roof yourself.
Misused Or Overlooked Flashing
Flashing is an essential part of the roof's structure because it helps to seal around things like your chimney, vent pipe, and more. Any time you install new roofing shingles, or if you replace the shingles around the flashing and have to remove it to do so, you'll need to install new flashing.
Many homeowners look at the existing material and opt to reuse it if it isn't visibly damaged. Unfortunately, you won't always get a proper seal when you reuse the flashing on a shingle roof, so you'll want to make sure that you install new material every time.
You also need to be sure that the flashing is properly secured and sealed. This will protect your roof from leaks and water damage. Your roofing contractor is the best source to ensure that this work is done properly.
Omitted Underlayment Barrier
Another common mistake that many homeowners make when they install a shingle roof is to install the shingles directly to the roof decking. This can be a costly mistake because it can leave your roof vulnerable to moisture. You should always have a waterproof barrier installed over the roof decking before you apply your shingles.
Your roofing contractor will ensure the application of the proper underlayment for waterproofing and other barrier protection. Then, the shingles can be applied atop that barrier for a comprehensive, protected roof.
One thing many homeowners don't even think about when they install their own roof is the fact that self-installation often voids the shingle manufacturer's warranty. If you have any defective shingles that crack, crumble, or otherwise fail within the warranty period, you'll have to prove that the roof was professionally installed within the requirements of the product warranty. Otherwise, the shingle manufacturer may not address the problem. Talk with a shingle roof installation contractor to schedule your new roofing installation so that you can preserve your warranty.
These are just a few things that homeowners should understand before trying to install a shingle roof on their own. Talk with your local roofing contractor today for more help.
