Asphalt roofing can be prone to splitting and cracking depending on some factors like roof quality, local climate and underlying roofing issues. The important thing, however, is to repair these problems immediately. Otherwise, the cracks and splits that have developed on your roof will expose the sheathing and make it susceptible to water damage.
When fixing shingle cracking or splitting, it’s important to know the difference between the two since they occur in distinct conditions. Of course, knowing the cause of the problem is crucial to a long-lasting repair, so you have to identify your roof problem correctly.
Shingle cracking is the result of the roof aging or being exposed to moisture. Craze-cracking that occurs because of aging is common in organic or fiberglass shingles. In other cases, it is due to an excessive amount of filler in the asphalt mix, a weak mat or poor-quality shingles.
It’s also possible that the shingles have lost volatiles because of evaporation or moisture. These volatiles are typically added to the asphalt mix to make the shingles flexible and waterproof. So, when these volatiles are diminished, the shingles often dry up and shrink. They become less flexible, so they eventually crack.
Temperature fluctuations are the main cause of shingle splitting. When the temperature outside is warm, this usually causes the shingles to expand. The joints between the shingles then decrease in size. When the temperature is cold, the shingles contract causing the joints to become bigger.
Apart from the temperature’s effect on the underlying joints, the shingles connecting these joints also tend to shrink, and the bridging shingles get strained. This often leads to the reduced effectiveness of adhesive strips, which ultimately causes the splits in the roof shingles. Shingle splitting can occur in diagonal patterns or randomly throughout your roofing. Make sure to have it fixed immediately so as to avoid the risk of leaks and wind damage.
