What characterizes a steep roof?

A steep roof is characterized by having a slope greater than 4:12, which means for every 12 horizontal units, the roof rises more than 4 vertical units. This inclination allows for better water drainage and reduces the likelihood of leaks. Steeper roofs often require specific construction techniques and materials to ensure stability and prevent damage during severe weather conditions. In contrast, a roof with no slope is flat, while those with a slope less than 4:12 fall into the category of low-sloped roofs. Such classifications are significant in construction, maintenance, and safety protocols, particularly regarding the requirement for fall protection when working on these types of roofs.
