Moment frame pitched roof.

To frame this style roof hip trusses are utilized from the main peak of the building stepping down with a flat top chord. The pitch of a roof is its vertical rise divided by its horizontal span and is a measure of its steepness. When using a truss 1 roof the framing process. It uses a single mono truss 1 and often has a pitch lower than 3 inches per foot 2 making it easy to roof but hard to maintain.

We know that the roofs are generally provided at top to cover and protect the structure from different weather conditions. In this design each side of the building has a roof pitch and eave.
