Many people use the terms “cracks” and “splits” interchangeably, especially when discussing asphalt shingle damage. What they don’t realize is that these two words have different meanings. Cracks usually happen on the surface of the shingles, while splits fracture the whole shingle. While they are different in that sense, both can put your roof at risk of losing its structural integrity. 

Colorado Roof Toppers, the top local provider of commercial and residential roof replacement, explains how shingle splits and cracks happen.

Shingle Splitting

Shingle splitting is usually caused by a combination of water penetration and thermal expansion and contraction. When heated during the day, shingles tend to expand and then contract during nighttime. This constant cycle of expansion and contraction often leads to splitting. Individual split shingles are easy to replace, but if it happens too often or occurs in too many tabs, you may already be due for a replacement.

Shingle Cracking

When your roofing contractor installs an asphalt roof, the shingles are actually layered with asphalt mixed with chemicals that provide more flexibility and durability for the roof. These chemicals are referred to as volatiles. As moisture seeps through the shingles and then evaporates, the volatiles gradually erode. This results in weaker shingles that are prone to cracking. Typically, this happens when a roof is old and near the end of its service life, so a good solution would be to plan for a roof replacement.
