2 3 roof pitch.

One method to find the pitch is to climb on the roof and measure the rise for a 12 run. The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12. Roof pitch refers to the slope which the rafter creates. You can go by the measurements taken by walking the roof.

The gentle slope of a 4 12 roof pitch falls on the cusp between moderate pitch and low pitch. A pitch of 2 12 is the minimum pitch for shingles made of asphalt so your roof just barely makes the cut off for one of the most popular roofing material options.
