In modern-day houses and favorable climes, roofs are used as a means to generate electricity for the home (solar panels). They are also used as an aesthetic element for buildings. They provide protection from rain, snow, sun, high and low temperatures, and other unfavorable environmental conditions. Roofs are required to prevent the ingress of unwanted elements. When all these are settled, the roof's configuration, usually defined by the pitch and rise, needs to be calculated.Ī roof is a structure that covers the top of a building or a vehicle. Roofing types, roofing designs, roofing materials, and roof categories are among the important considerations when constructing a building.
