How To Work Out Roof Slope

For a roof with the ridge above one wall the span is the same as the run.

How to work out roof slope.

Use a level against the underside of the rafter you re measuring to get the most accurate value. Using an online calculator. The most precise way to find the roof s slope is by measuring it from the underside.

This is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares. Calculate the rafter length substituting these values into the following formula. Then multiply the slope by 12 to get the rise. If you are going to be calculating the slope of the roof yourself you should consider.

If you are trying to learn how to measure roof pitch calculations accurately you should really consider the importance of using a calculator. 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. Calculate the roof pitch as the proportion of rise and run. There are a lot of people who do not want to go into or onto their roof to measure the slope.

How do you calculate the slope of a roof. Access one of the rafters then take. For a simple gable roof the span wall to wall will be twice the size of the run wall to ridge horizontally. Pitch rise run 1 5 6 25.
