How Do You Find The Slope Of A Roof

There s no need to simplify them.

How do you find the slope of a roof.

Low slope roofs are from 0 to 3 12 in pitch. As a shortcut the roof slope multiplier for any slope can be determined by finding the square root of rise run 1. Then enter the value of the run and choose the unit of measurement from the drop down menu. For example when a roof has a slope of 5 12 the roof is 5 inches high for every 12 inches long.

The slope of your roof is the ratio of the vertical distance or rise of the roof to the horizontal distance or run. Another way of stating this is that the roof has a rise of 5 and a run of 12. The horizontal distance in the ratio will be 12 while the vertical distance is the measurement you took from the rafters. For example if you find 4 inches of height with the tape measure at the 12 inch mark on the level your slope is 4 12 or 4 in 12.

Some sources consider low slope to include 3 12 pitch roofs. Here are the steps to follow for the roof angle calculator. Roof slopes are measured in units of twelves. Divide the rise by the run.

Using an online calculator. The slope of your roof is the ratio of vertical distance rise to horizontal distance run. Finally enter the value of the rafter length and. Just write down the measurements you found.

Notes to the table above. You can measure with twelve feet or twelve yards but in this article we will use twelve inches. Find the square root of that result if you know the roof slope in degrees simply find the secant using a scientific calculator.
