What does pitch mean on roof?

A pitched roof is a roof that slopes downwards, typically in two parts at an angle from a central ridge, but sometimes in one part, from one edge to another. The ‘pitch’ of a roof is its vertical rise divided by its horizontal span and is a measure of its steepness.

What is the best pitch of a roof?

For most home styles, roof pitches fall in a range 4/12 (a moderate) slope up to 8/12 (fairly steep). Examples of extreme slopes range from 1/4:12 (almost flat) to 12/12 (sloping down at a perfect 45-degree angle).
