How do i get the pitch of a roof.

This gives you the pitch of the roof. Enter any pitch or fraction of pitch to find angle. Here are a couple examples. Then enter the value of the run and choose the unit of measurement from the drop down menu.

Divide the slope by two to get the pitch. This is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations. Enter any angle or fraction of angle to find pitch. Find the tangent of the angle tan angle.

From the attic hold a level perfectly level and touching a rafter at one end. First enter the value of the rise and choose the unit of measurement from the drop down menu. If you do need to calculate the pitch an estimate or shortcut is usually more practical than measuring the roof s overall dimensions. Another method to find the roof pitch is to go into the attic and measure the rise for a 12 run of the roof rafters which allows finding the pitch without going on the roof.

For a simple gable roof the span wall to wall will be twice the size of the run wall to ridge horizontally. To measure the roof pitch you ll need an 18 or 24 inch level a tape measure and a pencil. Here are the steps to follow for the roof angle calculator. Finally enter the value of the rafter length and.

Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level.
