The Difference Between Shingle Cracking and Splitting

Asphalt shingle roofs are a standard choice among homeowners and contractors because of their reliability and affordability. Although asphalt shingles are a cost-effective roofing material, they’re also prone to certain issues, such as cracking and splitting.

In this article, asphalt and metal roofing expert Deschutes Roofing discusses the difference between shingle splitting and cracking.

What’s the Difference Between Cracking and Splitting?

At a glance, shingle cracking and splitting look similar. However, further examination will show the differences between the two. Shingle cracking appears as streaks of cracking on the surface of the shingle, while shingle splitting creates lines that split and go through the entire shingle. 

Cracking can also be visible on different areas of the shingle while splitting usually appears in a diagonal pattern starting from one end to another. Simply put, cracking is damage to the surface only, and splitting affects the entire shingle. If you’re unsure what kind of damage you’re dealing with, you should consult a residential roofing expert.

How Do These Cracking Shingle Issues Happen?

Shingle cracking typically happens when the asphalt shingle loses its volatiles due to aging, wear and tear, or moisture damage. Losing volatiles causes the shingle to shrink and cracks to form on the surface. This can also happen if the shingle was made or installed poorly.

Shingle splitting happens due to the stress on the asphalt shingles caused by constant expansion and contraction. Shingles expand when exposed to heat and slowly contract when the temperature cools down. This causes the adhesives on the upper side of the shingles to weaken, causing the shingle to split.
