Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level.

You can assess this in two ways either as the roof pitch angles which the rafters make with the horizontal or the proportion between the run and the rise of the roof. The 7 means that the roof rises 7 for every 12 it runs. To measure the roof pitch you ll need an 18 or 24 inch level a tape measure and a pencil.

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. Pitch tan angle where angle is the roof pitch expressed in degrees. On the roof hold the level perfectly level and measure the height from the roof to the level 12 inches away from where the level touches the surface this will be the rise. Often you express roof pitch as the ratio between the rise and the run in the form of x 12.
