Then enter the value of the run and choose the unit of measurement from the drop down menu.

How do you determine the pitch of a roof.

Roof pitch calculator results explained. For a simple gable roof the span wall to wall will be twice the size of the run wall to ridge horizontally. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. To determine the finished height of the ridge beam add the rise m and the y height.

Slope tan degrees. The 7 means that the roof rises 7 for every 12 it runs. This is the amount your roof inclines in a 1 foot span or the pitch of your roof. Even if you want to use a flat roof pitch calculator system you will be able to find one.

For more complex roofs you may need to calculate it section by section. First find the slope by finding the tangent of the degrees eg. Here are the steps to follow for the roof angle calculator. How to calculate roof pitch.

Rafter rise run from the pythagorean theorem. 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. Also referred to as roof slope or roof slant so what does the 7 12 in the example to the right mean. Finally enter the value of the rafter length and.

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. Roof pitch calculator is determined by the number of inches it rises vertically for every 12 inches it extends horizontally. The top of the ridge beam m y. To determine the y height measure from the bird s mouth up the calculated slope x in 12 to the top of the rafter.

The slope is the same as the pitch. Place the end of your level the 0 inch point of your 12 marking against the roof surface. Hold the level straight and level bubble centered and then measure the vertical distance down from the your 12 mark on the level down to the roof. Divide the slope by two to get the pitch.

Then multiply the slope by 12 to get the rise. If you want to know how to find the pitch of a roof then start with a calculator. First enter the value of the rise and choose the unit of measurement from the drop down menu. Pitch tan angle where angle is the roof pitch expressed in degrees.
