Have already sent you a e-mail, don`t think I was registerd. So here it goes. We are planning on replacing a roof with metal roof . Has got 3/4" plywood will be using tar paper. is there any other information that I need.
Answer:
Metal roof manufacturers often have instructions specific to thier product so the best I can do in the way of an answer is to suggest you read the brochure your new product comes with.
