I live in the foothills west of Denver, an area known for many devasting forest fires in the past 15 years. As a way of fire proofing my house, I am considering a standing seam metal roof. I have been told that with a metal roof I would not need to worry about flying embers starting a roof fire. In fact, I was told that with a metal roof, I would not need to worry about wetting an/or foaming the roof in the event of a fire - just to concentrate on the sides of the house. Then a couple of weeks later, I was told by a wild fire authority that metal roofs were not good since hot embers can land on the roof, heat the metal to a point that a fire will break out under the roofing. Who do I believe?
I currently have a 25 year old asphalt shingle roof that needs to be replaced within the next year. Does anyone have any suggestions or comments concerning my problem?

Many metal roofs are suitable for Class A, B, or C fire ratings, depending upon what type of underlayment is used beneath them. Once you choose a metal roof, inquire with the manufacturer as to their fire ratings and prescribed underlayments. These underlayments are designed to not only be fire resistant but also to act as a heat insulator so that the situation of the intense heat causing ignition of wood beneath the metal is unlikely to occur.
