Any big fans out here? Everyone seems to want prices on steel. THe pricing is not a problem if I know how I want it put down. Been lucky enough to talk myself out of the steel until now. Have 3 roofs to price out and am quite sure that someone will stick me with the steel
Did a few steel roofs with another contractor a few years ago..didn't care for doing them myself, but work is work. He had the roof stripped and layered 30# felt and went right over the roof boards (no plywood). Always wondered how the condensation thing would work out with all that dead air space in the attic....All the time knowing damn well that holes are being punched in the felt from previous nails.
Talked to the guy that handles the roofing at the local supplier and he says, lay OSB, felt and then the steel. Little to no airspace between steel and the roof deck means that there should be little to no condensation.
I believe my competition plans on laying down pearlins and laying the steel right over the whole roof. I would have to say a no no since it already has 2 layers of shingles on it so I won't be going that way.

I have seen this done before on roofs any takes on the pros and cons.
