Buildings consume one-third of all energy and two-thirds of all
electricity generated. Cool roofs can help reduce energy consumption
by lowering cooling loads. Lightly colored, more reflective roofs save up
to 40% in cooling energy, as reported by the Heat Island Group of
Lawrence Berkeley National Laboratory. Highly emissive roofs can lower
urban air temperatures, thereby benefiting the environment by reducing
smog formation.
Metal roofing has many attractive features. Its architectural appeal,
variety of profiles, textures and color, flexibility, and durability make it
popular for residential and commercial projects, both in low-slope and
steep-slope applications. Metal roofing and its finishes are inert, safe
materials that don’t pose a health risk. Metal roofing is tested for wind,
fire, and hail resistance, and listed with various building codes and
entities. Its non-combustibility can reduce the spread of fire in and
among buildings.
