These are utilized in residential applications.
Contemporary houses often have flat roofs which shouldn t be completely flat but should be around 1 40.
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.
