Pitch Finder For Roofs

Run 2 rafter 2 rise 2.

Pitch finder for roofs. 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. After finding out your roof pitch angles you can use the calculator to perform the calculations for you instead of doing them manually. You ll need a level that is 12 or longer and a tape measure. The rise is the height of the roof and the run is the horizontal span as pictured above.

X pitch 12 0 25 12 3. If you have the values for the rise and rafter you can find run using the following. Just write down the measurements you found. Roof pitch calculator the roof pitch calculator calculates slope pitch angle and rafter lengths based on input of rise m and run r.

Pitch finder take pictures accurate roof take offs measurements preview the roof on the map then save or import image blueprint access sketch tool and trace the roof to measure one plane at a time no need to set a scale unless using an image blueprint use positioning tool and tap points to reposition or delete. What is the roof pitch. It can be calculated either using rafter and rise or rafter and run both using the pythagorean theorem as a roof pitch finder. The slope of your roof is the ratio of vertical distance rise to horizontal distance run.

Recalculate this value into an angle. Pitch rise run 1 5 6 25. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. Calculate the roof pitch as the proportion of rise and run.

The pitch of your roof is 3 12. One method to find the pitch is to climb on the roof and measure the rise for a 12 run. For example if a roof has a pitch of 4 12 then for every 12 inches the building extends horizontally it rises 4 inches. All you need to do is just to rearrange the equations.

The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7. Use the diagrams on this page as a reference when inputting rise and run and while interpreting the calculated results. To measure the roof pitch you ll need an 18 or 24 inch level a tape measure and a pencil. Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level.

On the roof hold the level perfectly level and measure the height from the roof to the level 12 inches away from where the level touches the surface this will be the rise. There s no need to simplify them. The roof pitch is the slope of the rafter. The roof pitch calculator is a convenient online tool you can use to quickly assess the pitch of your roof to determine the length of rafters you need.

Here s an easy safe way to determine the pitch from inside your attic. The pitch is commonly defined as the ratio of rise over run in the form of x 12.
