Investing in quality products from reputable roofing and window manufacturers can help you avoid a long list of issues with your home. Two of the most common problems that develop with asphalt shingles are splitting and cracking. Both must be addressed immediately to prevent water damage to the roof’s sheathing. 

Continue reading to learn the difference between asphalt shingle cracking and splitting. 

What Is Asphalt Shingle Cracking?

During manufacturing, volatiles are added to the asphalt mixture to give shingles flexibility and water resistance. These chemicals have a low boiling point, and shingles slowly lose them due to moisture and evaporation. As your shingles age, the more volatiles they lose, causing them to shrink and crack. Heat can speed up this process, which can cause the surface of the asphalt to crack. This is one reason keeping shingles cool can help prolong their life. 

You’ll know your asphalt shingles are reaching the end of their life if you notice the presence of craze-cracking. This can also occur when there’s an excessive amount of filler in the asphalt mix. You likely have a weak mat or poor quality product if the shingles start cracking not long after installation. Reputable roofing and window installation contractors will only recommend long-lasting, top-grade products for your home. 

How Is It Cracking Different From Splitting?

Extreme temperature changes can cause expansion and contraction in asphalt shingles. They’ll expand when exposed to heat, causing the joints between them to reduce in size. When the temperature is cold, these joints will become bigger. This constant expansion and contraction due to temperature shifts will eventually cause the shingles to crack.
