When describing a specific type of asphalt shingle damage, the terms cracking and splitting are often used interchangeably. However, these are two different issues.
Genesis Roofing shares more information about shingle cracking and splitting in this post.
How Do Shingle Cracking and Splitting Differ?
Temperature changes cause shingles to split. The shingles expand during hot weather, causing joints to shrink in size. Once it gets cold, the shingles shrink and the joints between them expand. Thermal expansion and contraction can eventually put a strain on the bridging shingles, causing splits on the roof.
Meanwhile, organic or fiberglass shingles crack due to aging and moisture. Shingles have volatiles that make them flexible and waterproof. However, these chemicals evaporate over time, causing the shingles to become brittle and prone to cracking. If you have only recently installed your roofing system, cracking could indicate your shingles are low-quality or the mat is weak.
More Information on Why Shingle Cracking and Splitting Occur
Split or cracked shingles are more than just an eyesore. They create gaps that allow moisture to infiltrate the layers underneath, resulting in more extensive damage. The following elements can exacerbate the condition of cracked and split shingles:
- High-speed winds – When winds are strong and your shingles are already compromised to begin with, the wind can lift your shingles or blow them off your roof.
- Improper installation – A minimum gap between shingles is typically required to ensure there’s enough give for the shingles when they expand and contract. If the shingles are placed too close to each other, this will make them more prone to splitting.
