Metal Roofing Systems
Residential metal roofing systems are generally made of steel, aluminum, or cooper. Rolls of 24- or 26-gauge steel sheets are given a metallic costing to prevent rust, followed by a baked-on paint finish. Aluminum sheets don’t require the metallic coating but do typically get painted. Copper is neither coated nor painted, because it weathers without corroding. In many cases copper is used for special features, such as the roof of a prominent bay window, gutters, and downspouts. Steel roofing products are coated with either zinc (galvanized) or a mixture of aluminum and zinc (galvalume or zincalume). Of the two, galvalume typically offers the longest lifetime. The coatings are offered in multiple thicknesses-the thicker the coating the longer the life, and the higher the cost.
Life cycle costs
Metal roofing has been proven to be more durable than most other roofing systems available on the market. As a result, metal roofing has a low life cycle cost.
Metal roofing is sustainable and can contain significant recycled content. It lasts longer than most non-metal roofing and is 100% recyclable at the end of its useful life.
fire & wind protection
Metal roofing is extremely fire resistant. In addition to that, metal roofing systems can also be designed to withstand extremely strong winds.
Metal roofing is on the leading edge of technology with a wide variety of finishes, designs and colors that provide greater energy savings compared to most other non-metal roofing products on the market today.
