It’s not surprising that asphalt is the most common material used for residential roofs. It’s not only affordable and simple to install, but it also creates a traditional and uniform look in some neighborhoods.
While asphalt shingles can be a good choice for some roofs, they aren’t without their issues. If you’re going to spend money to replace your home’s roof, it’s important to understand the potential downsides of any choices.
Common Problems with Asphalt Roofs
The Asphalt Roofing Manufacturers Association reports that about four out of five homes use asphalt shingles for their roofing material. This isn’t shocking because it’s the most affordable upfront option. But, before you choose an asphalt roof for your next project, here some of the most common problems you might encounter with these materials.
A variety of factors can create blisters on your roof’s asphalt shingles. If they are small raised sections, this is often due to aging. Other potential causes are poor roof ventilation and manufacturing defects.
When an asphalt shingle starts to curl, this is often linked to moisture issues. Moisture can accumulate due to poor ventilation or even a manufacturer’s defect. Depending on how severe the shingles are curling, they can be either glued down or replaced.
When shingles begin to crack, this is generally part of the aging process. But, cracking can also happen due to stress from high winds or structural movement.
If an asphalt roof isn’t installed correctly, the shingles are more likely to “raise” off the roof deck. This happens because the shingles won’t be strong enough to withstand strong wind.
When installed, shingles must have the right type and number of fasteners. This is just one of the reasons why it’s vital that homeowners only work with an experienced roofing contractor that will install the system correctly and stand behind the manufacturer’s warranty.
Tearing or Thermal Splitting
When an asphalt roof is exposed to extreme temperature changes, it can experience thermal tearing, which is where the materials begin to crack and split. This is a serious issue that affects the integrity of a home’s roof and can allow moisture to enter the home.
Asphalt shingles are covered with many little granules, which can begin to deteriorate over time. When these start to disappear, the shingles are nearing the end of their useful life, and it’s time to think about replacing your roof.
