The roof s pitch is an important factor in determining roof cost for two reasons. Usually they come in the form of a roof pitch diagram chart but other times it will be presented to you in a conversion format. The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12. I have been considering putting a standing seam metal on an addition i am currently building.

There are smartphone apps available which can be used to sight a roof s pitch from the ground. Pitch is the term used to describe the angle slope or slant of your roof. First a very steep roof typically recognized as anything that s more than 6 12 pitch is generally considered not walkable and requires greater staging safety and labor to complete the roof properly.

This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.

In essence a roof pitch chart is provided as a rough guide usually by a roofing company to help you see what the average roof pitches tend to be. The pitch or steepness of a roof is often referred to in terms of the amount of vertical rise over a 12 horizontal run. The pitch is only 1 12. A pitch over 9 12 is considered a steep slope roof between 2 12 and 4 12 is considered a low slope roof and less than 2 12 is considered a flat roof.
