"Cracking" and "splitting" are two terms that are often used interchangeably, but when it comes to asphalt shingle issues, they refer to two different things. Understanding the difference allows you to get a more accurate evaluation of your roof's overall condition during a scheduled maintenance check.
What Is Shingle Cracking?
Asphalt shingles contain volatiles, which are chemical substances added to the asphalt mix to give the roofing materials their flexibility and waterproofing qualities. Aging and long-term exposure to the elements, however, leads to significant loss of volatiles, resulting in shrinkage and cracks. While it is mostly seen as a sign that a roof is nearing the end of its lifespan, shingle cracking may also happen in newer roofs, especially if the roofing material has a weak mat or is made using low-quality components. What Is Shingle Splitting? Temperature changes can cause asphalt shingles to expand and contract. While this is a normal occurrence, too much of it can weaken the underlying joints between the shingles, weakening the adhesive strips underneath. This leads to splitting, which then increases the roof's susceptibility to leaks and blow-offs. If the splitting occurs on a large section of the roof surface, you'll most likely require a roof replacement. How to Prevent Shingle Cracking and Splitting Generally, there are two ways you can prevent these roofing issues. The first one is to make sure that your asphalt roofing shingles are of decent quality. Lower quality materials tend to have weaker mats and, in turn, can lose volatiles quickly. To prevent premature aging of your asphalt roofing shingles, choose higher quality shingles that fit your budget. Don't hesitate to ask your local roofing contractor for suggestions on the best roofing shingle brands. The second way is to make sure that your roof is installed by a trusted and experienced roofer in your area. You can rest assured that your new roof is built to code without you stressing over them breaking suddenly. The pros will also be able to assess and install proper insulation and ventilation to help regulate the temperature of your attic and roof.
