I'm in hurricane torn biloxi,ms and FEMA has just put a layer of blue plastic with mesh in it on the roof so it won't leak until a new roof can be put on--I have put several steel roofs on before--right on the existing shingles--can I leave this tarp type material on the roof and put the steel right over it or could this be a problem with moisture or something else--it looks like tarp material with a mesh in it--like you would buy to cover your boat or etc. Jim

It is important to adhere to the instructions put forth by the metal roofing manufacturer. I think you will find that virtually all of us will want an underlayment over the existing shingles -- either 30 pound felt or a synthetic underlayment. For one thing, this keeps the back of the metal from being damaged by rubbing against the old shingles. Generally, I would remove the tarp before installation of the roof and install an appropriate underlayment.
