An asphalt shingle roof has flexible asphalt shingles as the ridge cap. Some roof shingles are non-combustible or have a better fire rating than others which influence their use, some building codes do not allow the use of shingles with less than a class-A fire rating to be used on some types of buildings. Due to increased fire hazard, wood ...
Nepal Building Codes (NBC) are a set of a technical documents developed by The Department of Urban Development and Building Construction under the Ministry of Physical Planning and Works of Nepal. The codes were first drafted in 1993–1994 and were adopted in 2003. It was included in the gazette in 2006. Adherence to the NBC is mandatory in ...
For impact resistance UL 2218 Class 4 is best. This increases survivability from hailstorms, but the shingles become more susceptible to hail damage with age. [9] Fire resistance: Forest fires and other exterior fires risk roofs catching on fire. Fiberglass shingles have a better, class A, flame spread rating based on UL 790, and ASTM E 108 ...

Fire-retardant materials should not be confused with fire-resistant materials. A fire resistant material is one which is designed to resist burning and withstand heat. An example of a fire-resistant material is one which is used in bunker gear worn by firefighters to protect them from the flames of a burning building.
Shock-resisting steels are designed to have high impact resistance , along with other properties such as strength, hardness. Silicon is a common addition to this class of steels, as it provides tempering resistance and increases toughness. [1]
