Wind Damage: How Does the Wind Affect Asphalt Shingle Roofs?

Wind resistance is one of the things you may have noticed, if you’ve been shopping around for a new asphalt shingle roof. A high wind resistance rating generally means your residential roofing system should be able to withstand the following effects:

Wind Damage: How Does the Wind Affect Asphalt Shingle Roofs?

Tab Uplift

The roof edge is a critical area of sloped roofing systems. When high winds hit the roofing plane, high air pressure is created at the leading edge of the first row of shingles. Low air pressure is simultaneously created at the top of the edge. Together, they create a force that pulls at the shingle tab, which can tear the shingles off the roof. The force increases with every row of shingle torn off.

This is why it’s important to invest in a roofing system that not only has high-wind-resistance ratings, but also has features like a reinforced starter strip. Proper installation is also important, so choosing an experienced roofing contractor – preferably one that holds certification form the manufacturer that they represent – can make a big difference.

Shingle Pull-Over

High winds can also exert force on the shingles and pull them over the heads of the fasteners. While it has the same effect as tab uplift, shingle pullover is more likely to happen if there are issues with the fasteners. It could be due to installation errors, or because the fasteners used are substandard. Shingle pull-over can be prevented by hiring a roofing contractor who uses quality roofing materials, and has the training and know-how to install them properly.

Creasing and Tearing

In some cases, the asphalt shingles have perfectly fine adhesives and fasteners, and will stay in place. However, they could bend far enough to form creases or get torn in half. When this happens, you’ll still see half-rows of shingles, where the fasteners are. This means the shingles are not stiff enough, and should be replaced with better quality ones.
