A small Butynol roof installation on a residential flat roof in New Zealand. Butynol roofing is a type of roofing material made from synthetic rubber, specifically butyl rubber. It is widely used in New Zealand and other parts of the world for flat and low-slope roofs due to its exceptional durability, flexibility, and waterproofing capabilities.
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.
A flat roof includes pitches as low as 1 ⁄ 2:12 to 2:12 (1 in 24 to 1 in 6), which are barely capable of properly shedding water. Such low-slope roofs (up to 4:12 (1 in 3)) require special materials and techniques to avoid leaks. [4] Conventional describes pitches from 4:12 (1 in 3) to 9:12 (3 in 4). [4]
Asphalt roll roofing or membrane is a roofing material commonly used for buildings that feature a low sloped roof pitch in North America. The material is based on the same materials used in asphalt shingles ; an organic felt or fiberglass mat, saturated with asphalt , and faced with granular stone aggregate.

This design improves efficiency. [13]
