Not a guru here but I can tell you that every metal roof that was put right on top of shingles here are about a mile to the north and west of the house it was on. The ones that were stripped with 2x4s and good long screws into the rafters are only 1/8 of a mile away with the rafters still entacted. Just kidding. These roofs were still on the houses. Some had minor damage and some were just fine. My old house was stripped with 2x4s and good screws and it survived Rita and I asked my Godfather( the person who bought it) and he said the roof survived Laura also. I hope this helps you.


It's hard to kiss the lips at night that chews your a$$ all day long.
