Pitched Roof Roof Structure Terminology

Roof slope is expressed as the ratio of a roof s rise vertical distance to each foot of run horizontal distance.

Pitched roof roof structure terminology.

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. It has a 1 4 pitch. 2 4 truncated duo pitched roof. A 4 in 12 pitch means the roof rises 4 inches for every 12 inches of horizontal distance.

Easily identified by their triangular shape gable roofs are generally two sided with a peak formed at the top hip. Pitched roofs are constructed in two ways. The word pitch was first used in the early 17th century to denote the highest point. The pitch of a roof is its vertical rise divided by its horizontal span and is a measure of its steepness.

This truss form is often introduced into domestic housing in conjunction with the conventional duo pitched roof to form an interesting roof line. All four sides slope downwards and are all equal in length to form a ridge at the top of the roof. Angle f equals angle g.
