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.

Roof pitch is simply the slopecreated by the rafter. Roof pitch is often expressed as a ratio between rise and run in the form of x 12. Here are a couple examples. Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level.

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. First measure 12 inches from one end of the level and make a mark. Divide the slope by two to get the pitch. Here s an easy safe way to determine the pitch from inside your attic.

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. 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 refers to the slope which the rafter creates. If you do need to calculate the pitch an estimate or shortcut is usually more practical than measuring the roof s overall dimensions. For example if the roof rises 4 feet and the span is 16 feet twice the run then the pitch is 4 16 or 1 4.
