How to calculate gable roof pitch.

The pitch of this roof is 4 8 12. The calculator above can handle much of this math. For a simple gable roof the span wall to wall will be twice the size of the run wall to ridge horizontally. Convert plate length amount of 12 6 into inches 12 12 6 150 inches.

A gable end is the gable and the wall beneath it. It can be looked upon as the part of the wall that seals the end of the roof structure. It is often compared to slope but is not exactly the same. Gable roof framing calculator plan diagram with full dimensions for a good straight fascia add an extra inch or 2 to the tails of all your rafters total length.

12 6 72 convert the inches back to feet. Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run. A gable is the part of the side wall of a building above a line between the eaves. When a gable consists of a sloping roof rather than a flat one the gable forms a triangle.

A speed square and level can be used to easily find the pitch of a roof. Outside of the u s a degree angle is typically used. Multiply this 12 by the roof pitch rise. Calculating the gable s square footage.

Calculate the height of a gable rake wall based on roof slope and half of the wall s horizontal length the rake run. Divide the rise by the run 5 12 0 4166667. If you do need to calculate the pitch an estimate or shortcut is usually more practical than measuring the roof s overall dimensions. Angle the angle of a roof is the same as the roof s slope except instead of being.

Split the gable into two triangles and form a rectangle 6 12 72 the total area for your gable. After they re up you can snap a line to mark and trim the tails in a nice straight line to make up for any ridge warp or marking cutting and fixing errors.

Slope the slope of a roof is represented as x 12 where x is the number of inches in rise for every 12 inches of run this is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares. Roof pitch calculator results explained. Here are a couple examples. Divide this amount by the run of the roof pitch.

72 12 6 at the highest point the gable is 6 high. 144 12 12. For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches. Bottom plate length 12 6 roof slope 5.

Divide the slope by two to get the pitch. What is the standard pitch for a roof.
