How Susceptible Is Your Asphalt Shingle Roof to Wind Damage?

Although your asphalt shingle roof is designed to withstand extreme weather conditions, it can still sustain wind damage in the long run. Since strong winds can lead to costly repair issues, you need to be aware of the factors that make the entire structure susceptible to this type of damage. Here’s how wind interacts with your asphalt shingle roof and the factors that affect the entire system’s wind resistance.

As the wind travels up to your roof, it hits the sides of your home and goes over your roof with changing degrees of uplift pressure. Uplift pressure is particularly highest at the eaves of your roof, which is why these areas are highly vulnerable to wind damage. When the wind reaches the surface of your roof, suction pressure can lift off your asphalt shingles.

Factors That Affect Your Roof’s Wind Resistance

When it comes to your roof, several factors affect its wind resistance such as:

• Location of your home. If you live in a hurricane- or tornado-prone area or where high winds usually occur, keep in mind that your roof is more vulnerable to wind damage than those in the city. To protect your home, consult your roofer about which roofing material is suitable for your climate.
• Age of your roof. As your roof ages, it grows weak and becomes more susceptible to wind damage. A 20-year-old asphalt roof, for instance, is more likely to sustain wind damage than a 10-year-old asphalt roof. If your roof has reached the end of its life span, it’s best to have it replaced to prevent further damage.
• Low-quality materials. The integrity of your asphalt shingle roof is only as good as the quality of your roofing materials. If you choose low-quality materials such as local generic plywood for the deck, your roof may not last for a long time. To prevent this from happening, invest in quality decking material that will withstand wear and tear.
• Poor installation. Roof installation requires a professional roofer for the task. Otherwise, you may end up with installation mistakes such as misaligned shingles or incorrect nail placement that can increase susceptibility to wind damage.
