One of the reasons why I don't live near the coast. but since I live in an area that had a tornado 100 years ago rip through the town that no longer exists I have house insurance and my metal roof is secured with long screws deep into the rafters not just the dinky things they used to screw to the decking. If my rrof goes in one of our freakish 80 to 90 mph wind storms I'd rather it take the whole house than just the roof
