Here are some important facts about metal roofing to consider:
- Noise. A metal roof installed over solid sheeting (wood planks, boards or plywood) will be as quiet as an asphalt shingles roof.
- Lightning. A metal roof does not increase the odds of your home being struck by a lightning. If a lightning does strike your home, a metal roof will safely dissipate the electric charge, even if it is not grounded. Metal Roofs act as a Faraday Cage (electrical shield) for your house. They disperse the charge over a larger area as compared to a little wire coming down your chimney or wall.
- Fireproof. Modern metal roofs such as aluminum standing seam have a class “A” or UL Class 4 fire retardant rating. If you live in a fire-prone area, a metal roof can help protect your home from a forest fire, as well as help you save money on your home insurance premiums.
- Insurance. Many insurance companies offer a significant discount (about 30%) on your homeowners insurance if your home is protected by a qualified metal roof. Ask your insurance agent about this.
- Snow. If you live in an area that sees a heavy snow fall, with freezing temperatures, a metal roof will shed off the snow, thus helping prevent a heavy snow accumulation and ice dams on your roof. A metal roof can easily be outfitted with snow-guards to prevent the sliding of snow over door entrances and other areas where heavy snow is undesirable.
- Solar. A standing seam metal roof can easily be integrated with PV solar panels should you decide to take your home’s energy-efficiency to the next level. A standing seam metal roof can be easily combined with either “Peel and Stick” thin-film photovoltaic solar laminates, or with traditional and somewhat more powerful crystalline PV solar panels. If your roof has a large area and faces south, or you are especially ambitious, then you can try to go off the grid completely!
