Factors that Can Affect the Wind Resistance of Your Roof

The roof is usually the first to take the blow during an extreme weather event. Even without rain or snow, asphalt shingles can still suffer damage from high winds. With enough force, winds can loosen shingle granules and even tear off portions of the roof.

Here are factors that affect your roof’s ability to withstand wind damage.

Installation

A well-installed roof will do a better job of standing up against high winds. Shingles must be nailed correctly to the decking. An experienced contractor knows the correct nails for shingles and how to use them.

Structure

The slope or pitch of the roof plays a significant role in its wind resistance. It affects how much air passes through the system and gets beneath it. Roofs with pitches between 4:12 and 6:12 are considered extremely wind-resistant. Moreover, the overhang is the part of the roof that stretches over the exterior wall. If your roof has a large overhang, it is more prone to wind damage.

Materials

The materials you choose for your roof can influence how wind-resistant it is. There are different classifications of shingles according to their wind resistance. For instance, Class D shingles can stand up to winds of up to 90 mph. The thickness of sheathing and decking can also affect a roof’s weather resistance.

Age and Maintenance

It’s normal for roofs to deteriorate and weaken as they age. Older asphalt shingles are more likely to sustain wind damage than newly installed ones. Fortunately, you can make your roof last longer and improve its ability to withstand harsh weather conditions with proper care. Make sure to schedule regular inspections and maintenance from reliable professionals.
