Investing in quality products from reputable commercial and residential roofing companies can help you avoid several problems in your home – including asphalt shingle splitting and cracking. These roofing issues must be addressed immediately to prevent water damage and expensive repairs. That said, it’s essential to understand how cracking and splitting differ from each other.
Read on for more information on asphalt shingle cracking and splitting.
How Do They Differ?
The primary distinction between the two is that a split runs through the entire asphalt shingle while a crack only affects the surface. What about asphalt shingle creases? Creases, which are typically caused by wind damage, are considered cracks unless they run the entire length of the shingle.
How Do Cracks Occur?
Cracks appear on the surface of asphalt shingles due to the evaporation of volatiles. Volatiles are chemicals added to shingles during manufacturing to make them flexible and waterproof. The loss of volatiles causes asphalt shingles to shrink, so cracks eventually form on the surface of the shingles. Cracks can also be the result of aging or the absorption of moisture.
However, if the shingles begin to crack soon after installation, you likely have a weak mat or a low-quality material. Only work with reputable contractors so you can have peace of mind that your roof will be installed properly and the materials have excellent quality.
How Do Splits Happen?
As temperatures fluctuate, your shingles expand and contract. Thermal movement stresses the material and weakens the adhesive strips on the upper surface of the shingles, resulting in diagonal splits.
