Asphalt Shingle Cracking VS. Splitting

Asphalt shingles, cracking, and splitting are among the most common roofing issues a homeowner may encounter. Once they are neglected, these can lead to more serious issues which may expose your roof’s sheathing and make it susceptible to water damage. Because they are used interchangeably, it’s ideal to understand how they exactly differ. Roof and window installation service expert Timberland Exteriors shares an overview of their comparison.

How Do They Differ?

Splitting occurs 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.

On the other hand, 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 can 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.

Why Do These Occur?

Despite modern asphalt shingle roofs being designed with wind resistance that has reinforcing adhesives at the shingle edges, high-speed winds, apparently, are a huge factor for both situations. Oftentimes, the wind may be too strong allowing to lift and fold the shingles. This is when cracks on the granule layer begin to appear and eventually, cause the splitting.
