The cracking and splitting are among the most common asphalt shingle roofing issues a homeowner may come across. These can lead to more serious issues which may expose your roof’s sheathing and make it susceptible to water damage once neglected. While the two are used interchangeably, it’s ideal to understand how they exactly differ. Here’s a guide by the local roof inspection company you can read.

Asphalt Shingle Cracking

Cracking VS Splitting

Cracking happens in organic or fiberglass shingles due to aging and moisture. Shingles are made with chemicals that make them flexible and waterproof, but these chemicals may evaporate over time. However, if you just had a new roof installation, cracking could be a sign that your shingles are weak and low-quality.

Storm damage repair experts say that on the other hand, splitting is known to be due to changes in temperature. Shingles tend to expand during summer, causing the joints between them to decrease in size. When the temperature drops during winter, the shingles shrink and the joints between them become larger along with the shingles connecting the underlying joints. This puts stress on the bridging shingles as all the bonded-shingle assemblies shrivel.

Why These Happen

High-speed winds are a huge factor for both situations, despite modern asphalt shingle roofs being designed with wind resistance. Keep in mind that, oftentimes, the wind may be too strong allowing to lift and fold the shingles. Now, this is when cracks on the granule layer begin to appear and eventually, cause the splitting.
