The Difference Between Shingle Cracking and Splitting

Asphalt shingles sometimes develop cracks and splits. If neglected, these issues can cause leaks that will require a roof repair or replacement. Although these types of roof damage may seem similar, there are significant differences between shingle cracking and splitting. 

Shingle Cracking and Splitting

Continue reading as Kroll Construction, one of the trusted roofing contractors in the area, explains how these two roofing issues differ from each other.

Cracked vs. Split Shingles

The main difference between the two is that splitting occurs throughout the entire shingle while cracking only affects the surface of the shingles. Creases on asphalt shingles, which are usually caused by wind damage, are considered cracks unless they go through the entire shingle.

How Cracks Form 

Due to evaporation, moisture or aging, cracks form on the surface of asphalt shingles. They can also be the result of shingles losing volatiles, which are chemicals added to asphalt shingles to make them flexible and water-resistant. The loss of volatiles causes asphalt shingles to shrink, eventually leading to the formation of cracks on the surface of the shingle.

There are also instances when cracking happens on a new roof. Typically, this is caused by low-quality shingles or a weak mat. To avoid this problem, it’s best to use roofing materials from trusted manufacturers.

How Splits Form 

Shingles expand as temperatures rise, and contract as temperatures drop. This reaction makes the joints beneath the shingles increase and decrease in size. Over time, the stress from repeated thermal movement can weaken the adhesive strips on the upper surface of the shingles. This can lead to the formation of diagonal splits on the roof’s surface.
