Underlayment for Metal Roof | Ask The Experts Forum

Guest User 4/26/2007	I have an Asphalt shingle roof with 1 layer of shingles on a 4/12 pitch. The shingles on the north side are in good shape, and the shingles on the south side are just beginning to curl. The roof has never leaked. I would like to put on a metal roof(overlapping panels installed vertically). Can I install the metal panels over the shingles if I cover the shingles first with felt paper. How much should I let the panels overhang the roof at the bottom? And should I use the rubberized paper product on the bottom edge to prevent Ice buildup?

Todd Miller Isaiah Industries, Inc. 4/26/2007	Most metal roofs could be installed over this, with an appropriate underlayment as specified by the metal roofing manufacturer. Ice and watershield over the eaves is a good idea and may be required by code where you're at. It odes not prevent ice buildup but can prevent water intrusion. As far as the overhang of the panels -- totally dependent on the product you install -- is specified by the manufacturer.
