Steep Slope Roofing Materials
Steep Roof Materials are roofs that are only recommended where water can freely and openly drain off the edge of the roof without retaining water for too long. The aim is to drain off water completely due to the high water permeability of most of these materials, for instance: the Thatched roofs. In areas where the International Build Code or similar is utilized, the minimum slope required is 2:12, though some countries extend this as high as 4:12

and is characterized by its high resistance, impermeability, and longevity. While there are an infinite variety of how to produce metal roofing, thicknesses, and types for metal/finishes used, roofing is generally grouped into 2 categories: Exposed Fastener Panels and Hidden Fastener Panels. Exposed Fastener panels are held down by fasteners through the outside of the metal, whereas Hidden Fastener Panels are held by hidden fasteners, clips, and sometimes adhesives. Typical metals include Galvanized Steel, Galvalume, Aluminum, Copper, or Vinyl 9Which while not metal is included in many cases for its matching profiles).

''Gal iron'' or ''Corro'' was the most extensively used roofing material of 20th century Australia, now replaced in popularity by steel with longer-lasting, coloured, alloy coatings.

Copper roofs can last for hundreds of years. Copper roofing offers durability, ease of fabrication, lighter weight than some other roofing materials, can be curved, low maintenance, corrosion resistance, low thermal movement, lightning protection, radio frequency shielding, and are 100% recyclable. Copper roofs have a high initial cost but very long lifetime: tests on European copper roofs from the 18th Century showed that, in theory, copper roofs can last one thousand years. Another advantage of copper roofing systems is that they are relatively easy to repair.
* Standing-seam metal with concealed fasteners.

The edge of each roll is fastened through ridged insulation into structural deck, and the proceeding roll is lapped over the fasteners. The overlap is then heat-welded with hot air to create a mechanically fastened thermoplastic roof. PVC is also known as IB.

Modified Bitumen are long rolls of asphalt-based materials, that can be heat-welded, self-adhering asphalt-adhered, or installed with adhesive. Asphalt is mixed with polymers such as APP or SBS, then applied to fiberglass and/or polyester mat, seams sealed by locally melting the asphalt with heat, hot mopping of asphalt, or adhesive. Lends itself well to most applications.
Built-up roof membrane (BUR)
Built-Up Roofs consist of multiple plies of bitumen-coated organic felt, polyester felt, or coated fiberglass felts. Three to five plies of felt are laminated to each other and to the substrate with hot asphalt, coal tar pitch, or made-for-purpose cold adhesive. Although the roof membrane can be left bare, it is typically covered with a thick flood coat of the bituminous adhesive and covered with gravel, mineral granules, or a reflective coating, each of which protects the BUR from ultraviolet (UV) light degradation (UV causes evaporation of tar and oxidation of asphalt). Gravel not only provides UV protection, it also helps accommodate sudden temperature changes (thermal shock), protects the surface from hail and mechanical damage, and increases the weight of the roof system to resist wind blow-off.
