Bituminous shingles, also called "shingles," consist of a fiberglass or cellulose felt reinforcement and a mixture of bitumen and mineral granules. Various shapes are available: rounded, rectangular, and scale-like. These products are easily installed on low-slope roofs and lightweight structures due to their low weight.
Flat roofs, or "low-slope" roofs, are also commonly found on commercial buildings throughout the world. The U.S.-based National Roofing Contractors Association defines a low-slope roof as having a slope of 3 in 12 (1:4) or less. [2] Flat roofs exist all over the world, and each area has its own tradition or preference for materials used.
A more recent design is the installation of a roof deck with foil-backed foam along with a second deck that is air-gapped away from the foil-backed foam to allow air to flow vertically to a ventilation outlet at the peak of the roof—it is a double-deck design with an air gap. This design improves efficiency. [13]
A shed dormer can provide head room over a larger area than a gabled dormer, but as its roof pitch is shallower than the main roof, it may require a different roof covering. Wall dormer As opposed to the dormer being set part way up the slope of the roof, this is a dormer whose face is coplanar with (shares the horizontal position of) the face ...
Neo-Mansard, Faux Mansard, False Mansard, Fake Mansard: Common in the 1960s and 70s in the U.S., these roofs often lack the double slope of the Mansard roof and are often steeply sloped walls with a flat roof. Unlike the Second Empire, where upper story windows were contained within dormers, Neo-Mansard roofs have window openings cut through ...
A level architectural deck may be intended for use by people, e.g., what in the UK is usually called a decked patio. "Roof deck" refers to the flat layer of construction materials to which the weather impervious layers are attached to a form a roof, and they may be either level (for a "flat" rooftop) or sloped.
TDDs harvest daylight through a roof-mounted dome with diameters ranging from about 10 inches for residential applications to 22 inches for commercial buildings. Made from acrylic or polycarbonate formulated to block ultraviolet rays, the dome captures and redirects light rays into an aluminum tubing system that resembles ductwork.
Mechanically seamed metal with concealed fasteners contains sealant in seams for use on very low sloped roofs, suitable for roofs of low pitch such as 0.5/12 to 3/12 pitch. Flat-seam metal with or without soldered seams. Steel coated with a coloured alloy of zinc and aluminium. Stone-coated metal roofing.
