In this design each side of the building has a roof pitch and eave. However in practise they tend to be much shallower commonly being expressed as a gradient and can be anywhere from 1 40 to 1 80. Pitched roofs are generally used where rainfall is heavy. The pitch of a roof is its vertical rise divided by its horizontal span and is a measure of its steepness.

The flat portion is increased the nearer the truss is to the end wall. When using a truss 1 roof the framing process. The roof pitch is typically set to 5 10º with portalised bays at 6 8m centres longitudinally. D connections between rafter and column eave joints and splice in the rafter at apex apex joint.

A pitched roof is in contrast to a flat roof which technically is any roof with a slope less than 10. To frame this style roof hip trusses are utilized from the main peak of the building stepping down with a flat top chord. A hip set is then used to frame the 6 or 8 feet nearest the end wall.

Robin is working on an extension so we thought we d shadow him for the day and see how he creates a pitched roof or semi pitched roof leading up to a flat. We know that the roofs are generally provided at top to cover and protect the structure from different weather conditions.
