Pitched roof roof structure terminology.

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

This is the most common roof shape with equal pitches on either side i e. Pitched roofs are constructed in two ways. All four sides slope downwards and are all equal in length to form a ridge at the top of the roof. Angle a equals angle b.

Roof slope is expressed as the ratio of a roof s rise vertical distance to each foot of run horizontal distance. It has a 1 4 pitch. A 4 in 12 pitch means the roof rises 4 inches for every 12 inches of horizontal distance.
