Pitch finder for roofs.

The pitch of your roof is 3 12. Use the diagrams on this page as a reference when inputting rise and run and while interpreting the calculated results. 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. X pitch 12 0 25 12 3.

To measure the roof pitch you ll need an 18 or 24 inch level a tape measure and a pencil. Just write down the measurements you found. It can be calculated either using rafter and rise or rafter and run both using the pythagorean theorem as a roof pitch finder. 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.

Pitch rise run 1 5 6 25. One method to find the pitch is to climb on the roof and measure the rise for a 12 run. First measure 12 inches from one end of the level and make a mark. Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level.

There s no need to simplify them. It can also be written down as 25 or 14. Recalculate this value into an angle. What is the roof pitch.

All you need to do is just to rearrange the equations. The slope of your roof is the ratio of vertical distance rise to horizontal distance run. 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. Here s an easy safe way to determine the pitch from inside your attic.

The roof pitch is the slope of the rafter. 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. 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 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. If you have the values for the rise and rafter you can find run using the following. The pitch is commonly defined as the ratio of rise over run in the form of x 12. You ll need a level that is 12 or longer and a tape measure.

Angle arctan pitch arctan 0 25 14 finally you can find the roof pitch in the form of x 12. After finding out your roof pitch angles you can use the calculator to perform the calculations for you instead of doing them manually.
