We are looking to have our roof redone and would prefer a metal roof. The old roof needs to be completely torn off. Some contractors have told us we need to put a layer of plywood down first, and some have told us we only need 2x4 furring strips underneath. The roof is a 9/12 pitch. What's the correct way to go?
The answer to your question depends upon what type of metal roofing you select. A good place to start your research is with the Metal Roofing Alliance's website at www.metalroof.org. Once you select a product(s) you like, contact the manufacturer with your installation questions. Best Regards. Todd Miller, President, Classic Products, Inc.
