![]() ![]() High-pitched roofs often require additional fasteners.They are the easiest ones to construct, and they are safe to walk on. Conventional roofs have the pitch ranging from 4:12 to 9:12 (33.3% to 75%).These are generally difficult to maintain, as they require special materials to avoid leaks. Low pitched roofs have the pitch below 4:12 (33.3%).Generally, these roofs have a pitch from 1/2:12 to 2:12 (from 4.2% to 16.7%). Flat roofs are not perfectly flat in reality – they need a small slope for water runoff. ![]() We can divide roofs into the following categories: For example, a pitch of 1:12 means that for every twelve yards of building length, the rise will be equal to one yard. Roof pitch is often expressed as a ratio between rise and run in the form of x:12. It can be assessed in two ways – either as the angle the rafter makes with the horizontal or the proportion between the rise and the run of the roof.
