Roof Slope Finder

This is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares.

Roof slope finder.

Calculate the roof pitch as the proportion of rise and run. First find the slope by finding the tangent of the degrees eg. If you know the angle of the roof in degrees you can find the roof pitch by converting the angle in degrees to a slope then finding the rise by multiplying the slope by 12. Slopes greater than 18 12 are found on a frame roofs and some mansard style.

Then multiply the slope by 12 to get the rise. How do you calculate the slope of a roof. If asphalt shingles are to be installed on a low slope roof special steps are required to avoid short roof life and roof leaks. Measure the rise of your roof.

If you want to know how to find the pitch of a roof then start with a calculator. Rafter rise run 1 5 6 2 25 36 38 25rafter 38 25 6 18 m. Access one of the rafters then take. Low slope roofs are from 0 to 3 12 in pitch.

Even if you want to use a flat roof pitch calculator system you will be able to find one. Use a level against the underside of the rafter you re measuring to get the most accurate value. Roof pitch calculator results explained. Pitch rise run 1 5 6 25.

Locate the level s 12 inch mark. This will allow your project to carry the depth and detail in the roof that you wanted as well as make sure that it will maintain a sturdy and effective nature throughout. Some sources consider low slope to include 3 12 pitch roofs. 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.
