Course modified date: 28 Jun 2022

In this course, learn about flat roof structures and construction.

Introduction 

Flat roofs are the simplest type of roof construction and the cheapest to construct. However, these benefits also have some drawbacks, as they tend to leak and need a lot more maintenance than pitched roofs.
Despite the name, a flat roof is not flat, they are built with a slight pitch, running from the highest level, often abutting another part of the building, away to the lower end, where water run-off is collected in guttering.

The angle of a flat roof is approximately 10°and this translates into a slope ratio of approx. 1:60 to 1:80, i.e. every 60 cm of running length, the drop would be 1 cm.
