I have an older metal roof. The screws were replaced by a company with a size larger. Some of the rubber washers or distorted showing signs of being over torgued. How many times can you change out to a larger screw? Would changing to even larger screws compromise the supports the tin is secured to? or would it be better to have new metal sheets and screws install.
