Asphalt Shingle Cracking Vs. Splitting

When you think about asphalt roof damage, you might think that cracks and splits are the same thing. While they share some similarities, there are distinct differences between the two issues. Cracking occurs on the shingle’s surface, while splitting refers to the roofing material suffering fractures. Both of these issues can cause severe damage in the long run if left untreated, leading to moisture getting into your underlayment and decking.

In this post, your trusted local roofing contractor, Shine Construction Inc, shares the difference between asphalt shingle cracking and splitting.

Asphalt Shingle Cracks

The asphalt mix used during the manufacturing process contains volatiles. These certain components allow your asphalt shingles to become flexible and waterproof. However, these volatiles will lose their efficiency over time, causing the roofing material to dry, shrink and crack.

Sustained exposure to heat can hasten your shingle’s cracking, also known as craze-cracking. Cracks are a common indicator of aging. However, if it happens on a new roofing system, then this means that subpar mixtures or materials were used during the installation process. If it worsens, it may warrant a roof replacement.

Asphalt Shingle Splitting

When your roof is exposed to extreme heat, this will cause your asphalt shingles to expand. They will contract once the weather starts to cool due to the changes in temperature. Thermal stress occurs due to this continuous cycle, leading to your shingles splitting. Another probable reason for causing shingle splitting is the adhesives used to secure your shingles. Having an excessively strong adhesive could lead to your roof becoming less resistant to wind shears, leading to splits and tears when strong gusts of wind blows your roof.
