I know you’ve seen it. When a roof looks like it’s been through a hurricane except we aren’t anywhere near the ocean. Fortunately we don’t have to worry about many natural disasters but heavy winds is nothing new in our region. With an average wind speed of 9.3 in Minnesota, you would think that we would never know what it looks like to see a blotchy roof as it can take over 130 mph winds in order to remove shingles from their bonding, which is only true with special wind protection. Mother nature is a tough one to beat. That’s why we carry GAF Shingles.
