It is all a matter of finding the right metal roof for that pitch. 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. Flat roofs which aren t perfectly flat require a small slope to allow for water runoff. Or the colon can replace the slash as in 2 12 or 7 12.

The maths behind this number is that it is the square root of rise run 2 1. 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.

A roof pitch multiplier also known as a roof pitch factor is a number that when multiplied by the area covered by a sloped roof gives the actual area of the roof. The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12. Resilient asphalt shingles lie much flatter to the substrate than slate tile and concrete which keeps water from being easily blown under them. These roofs have a pitch less than 4 12.

Roof pitch designations are comprised of two numbers indicating a ratio.
