How Do I Figure Out The Pitch Of My Roof

Often you express roof pitch as the ratio between the rise and the run in the form of x 12.

How do i figure out the pitch of my roof.

Divide the slope by two to get the pitch. For a simple gable roof the span wall to wall will be twice the size of the run wall to ridge horizontally. Pitch is the incline of the roof represented as the ratio of rise to the span twice the run. Here are a couple examples.

Here s an easy safe way to determine the pitch from inside your attic. It is often compared to slope but is not exactly the same. If you do need to calculate the pitch an estimate or shortcut is usually more practical than measuring the roof s overall dimensions. To measure the roof pitch you ll need an 18 or 24 inch level a tape measure and a pencil.

Roof pitch roof pitch is the measurement of a roof s vertical rise divided by its horizontal run. Roof pitch is simply the slopecreated by the rafter. 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. Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level.

Roof pitch refers to the slope which the rafter creates. Roof pitch is often expressed as a ratio between rise and run in the form of x 12. First measure 12 inches from one end of the level and make a mark.
