Wind Damage to Asphalt Roof Shingles | Your shingled roof is one of the most durable surfaces of your entire home. Most new asphalt shingle roofs are designed to last at least 25 years. Shingle manufacturers may even offer a wind warranty if your roof was damaged due to high winds that did not exceed the warranty limit. However, wind damage may be subtle and only likely to be noticed by a trained roofing contractor. Here are some tips of things to look for that can help you spot wind damage to asphalt shingles.

Missing Shingles

This is obvious but may actually be a bit difficult to spot on roofs where the shingles create a three dimensional pattern such as a cedar shake look. On a solid color roof, it is easy to spot missing shingles by just looking for a dark spot. Some roofs are a pattern of light and dark colors to give it dimension, making it easy to miss a single missing shingle. If you have a digital camera, take some pictures and view them zoomed in on a computer. The closeup look can help you spot missing shingles.

Lifts and Curls

Shingles are installed by roofing contractors from the bottom up with the next layer partially overlapping the one below it. Underneath shingle tabs is an adhesive strip that is activated in the heat of the sun to make the exposed tabs stick to the shingle underneath it. High winds can break this seal, making shingles curl or lift. Any shingles that are not perfectly flat against the one below it are likely wind damaged.

Cracks

Horizontal cracks are a sign that a shingle tab was lifted when the wind was blowing. It may have flattened back out, especially if it is particularly hot outside, but damage was done. The flexing of the tab runs deep, and the protective granulated surface has been compromised. Vertical cracks may be a sign of impact damage from falling debris such as tree limbs.
