The roof on my house now is leaking really bad and my husband decided we should put a metal roof on because it would be cheaper than fixing all of the problems we have with the existing roof. I have searched the web until my head hurts. Can you tell me where I can get detailed instructions and pictures on how to install a metal roof? I keep joking my husband when he decides to fix our house problems that he is no "Bob Villa"...Please help me before my husband ruins our house. Your response would help greatly.
