The slope of the roof depends on the type of tile chosen for building the construction (so, there are models that support higher slopes and others that do not support them. That’s why there is a regulatory rule imposed for each type of tile). The NBR responsible for coverage is 5720 nb 344. The most commonly used tiles at a construction site is the ceramic tile that is regulated by the NBR 8039, and it supports up to a slope of 36%, higher slopes than these can lead to problems such as gutters. The images are showing the dimensions, angles and calculation methods used for building a roof on a building. Check them out!
