How Do I Figure Out The Pitch Of My Roof

Roof pitch roof pitch is the measurement of a roof s vertical rise divided by its horizontal run.

How do i figure out the pitch of my roof.

In the united states a run of 12 inches 1 foot is used and pitch is measured as the rise of the roof over 12 inches. For a simple gable roof the span wall to wall will be twice the size of the run wall to ridge horizontally. Roof pitch is often expressed as a ratio between rise and run in the form of x 12. Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level.

It is often compared to slope but is not exactly the same. Divide the slope by two to get the pitch. Roof pitch refers to the slope which the rafter creates. To measure the roof pitch you ll need an 18 or 24 inch level a tape measure and a pencil.

It can be assessed in two ways either as the angle the rafter makes with the horizontal or the proportion between the rise and the run of the roof. Roof pitch is simply the slopecreated by the rafter. Here are a couple examples. First measure 12 inches from one end of the level and make a mark.

Pitch is the incline of the roof represented as the ratio of rise to the span twice the run. 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. Here s an easy safe way to determine the pitch from inside your attic.
