How To Find The Slope Of A Roof

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.

How to find the slope of a roof.

How do you calculate the slope of a roof. By slope angle formula steepness can be obtained by dividing vertical rise by horizontal span. As a shortcut the roof slope multiplier for any slope can be determined by finding the square root of rise run 1. In civil engineering the slope is the numerical measure of the steepness of a roof.

In the imperial unit of measurements the slope is expressed with the rise and run. Roof slope is also called as roof pitch. Divide the rise by the run. The most precise way to find the roof s slope is by measuring it from the underside.

For example if the roof slope is 45 then sec 45 1 414213. The slope is the same as the pitch. For more complex roofs you may need to calculate it section by. Access one of the rafters then take.

This is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares. Use a level against the underside of the rafter you re measuring to get the most accurate value. For a roof with the ridge above one wall the span is the same as the run.
