This article describes and illustrates the different types of support that prevents roof sagging and wall bulging at buildings, including definitions of collar ties, rafter ties, and structural ridge beams. In accordance with Pythagoras theorem, a 2 + b 2 = c 2 Roof Framing: collar ties, rafter ties, tension beams & structural ridge beams: some of these can support the roof and prevent ridge sagging and wall spreading.

The length of roof rafter is measured as follow based on the data provided below :- Revit Roof slope can seem complicated at first glance, but by learning a few critical features you can create any roof shape you desire. A rafter is one of a series of sloped structural members such as wooden beams that extend from the ridge or hip to the wall plate, downslope perimeter or eave, and that are designed to support the roof deck and its associated loads. Simply stated, the run is the distance half of span. In roof framing, the run is the distance from the outside of the wall’s top plate to a point directly below the center of the ridge. Simply put, the run is the span's half size.
Run Of Roof: The run belongs to the distance from the exterior of the top plate of the wall to a point directly underneath the center of the ridge in roof framing. A pitch ranging from 4/12 to 9/12 is the most common roof pitch. It differs with culture, environment, style, and existing materials. There is not any existence of standard universal roof pitch. As for instance, there is a 6/12 pitch on a roof that goes up 6 inches per 12 inches of horizontal run.
The angle, or pitch of a roof, is measured by the number of inches for each 12 inches horizontal expansion. Pitch Of Roof: A roof's pitch refers to its vertical elevation across its horizontal span. Rise Of Roof: This is the vertical gap from the top of the ridges to the wall.
