Roofing

May 2, 2024 4 minute read

Roofing, the protective covering over a building, protects its interior from its exterior environment. A roof can be simple or complex, flat or sloped, and pitched as a single structure or as multiple structures. Roofing may be planned and constructed along with the building project or added later, as a standalone project of renovation or repair. It may be composed of one or more types of roofing materials and is laid over a roof structure. The roof structure, sometimes referred to as a roof deck, supports the roof material from below. The type of roof structure used will depend upon the type of roofing material and its location.

How Roofing is Classified

Roofs are classified by their shape, material, and slope, which can be described as flat or pitched. Flat roofs are horizontal and have a slope of less than 3:12, which means every 12 horizontal feet, there are 3 vertical feet. Pitched roofs have a primary slope of 3:12 or greater. Some roofs may incorporate features of both flat and pitched roofs.

Materials Used in Roofing

While a wide range of materials have been used for roofing over the centuries, from thatch and mud to bamboo and metal, today metal, tiles, and shingles are among the most common materials.
