# 9 X 12 Roof Pitch

### 9/12 roof pitch to angle 36.87 degrees.

9 x 12 roof pitch. Calculating surface area using the roof pitch chart 10/12 roof pitch angle = 39.81 degrees.

The way pitch, also known as roof slope, is measured is rise over run. The first is from the top of the roof.

The pitch is around 6:12 to 9:12. Roof pitch is indicated by a number over a number.

A low slope roof is anywhere from 2 in 12 to 4 in 12. Pitches of less than 2/12 are considered flat roofs, even though they may be very slightly angled.

A 12 in 12 roof can cost up to 50% more than a 4 in 12 roof. In the usa, the range of standard pitches is anywhere between 4/12 and 9/12.

The roof pitch is a measure of roof steepness. Decide on the width of the building.

9/12 roof pitch angle = 36.87 degrees. This would also mean it raises at least 3' in 12'.

If a roof rises 10″ in a length of 12″, this is 10/12 roof pitch. Since two rafters are needed, we must divide this number by two.

There are two suggested ways to measure a roof pitch. If your roof is not flat and you cannot climb to the peak to get accurate width measurements then you can add a multiplier for the pitch of your roof.
