How to calculate pitch from rise and run

roof pitch
In this article, we will talk about calculating the roof pitch (US ), using
- Rise - is the total height of the roof - if the roof extends below the attic, we consider the extension too.
- Run - is half of the roof width. If roof extends the footprint of the house, we consider the extension too.

How to calculate the pitch

Let's say we have a Rise of:
And let's say we have Run of:
We find the grade factor (A) :
A = Rise / Run
A = /
A =
Pitch is A x 12:
pitch = x 12
pitch =
Pitch is = / 12
