4 different types of winds that can damage your roof

Your roof is designed to resist damaging weather conditions. But over time, as it experiences continuous exposure to wind, rain, heat, storm, etc, it starts to lose its strength. 

Strong winds is one such natural process that can cause severe damage to your roof. In 2020 alone, NOAA Severe Weather Database reported over 16,000 wind damage reports.

But bear in mind, the wind doesn’t have to be strong in order to cause such damage. Even a slow gust can easily raise the shingles off your roof, exposing your home to all kinds of rain & water damage. And the worst part, this damage won’t even be visible until it results in leaks and further destruction.

Old roofing systems are more prone to wind damage, but a new roof can just as easily be affected if not taken care of. And since it’s hard to predict the scale of wind damage, it’s best to hire a professional to inspect your roof after high winds or storms.

And in order to stay more aware of this situation, you should take a closer look at what types of wind causes roof damage:
