Understand Roof Pitch

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

Understand roof pitch.

In the roofing trade the go to term is pitch and it is expressed in terms of 12 inches so the pitch of a roof is determined by how many inches the slope rises for every 12 inches it runs horizontally. In this instance we want to take a look at how this can be changed and improved with the help of a roof pitch chart. Pitch angle incline slope they all can be used to refer to the steepness of a roof. Roof pitch roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run.

A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch. For example if a roof is 8 feet high and spreads out from the center covering 12 feet in each direction the rise over the run would be 8 12. You ll often hear experts express pitch as x over y. Technically roof pitch is the ratio of total vertical roof height the rise to total horizontal distance from wall to wall the span.

Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. Mathematically the pitch of a roof is different calculation than roof slope. The rise is the height of the roof from the base to the top. How to measure roof pitch to measure the roof pitch you ll need an 18 or 24 inch level a tape measure and a pencil.

A 12 to 24 pitch is expressed as 1 2. Pitch compares the roof s span to the rise while slope compares rise and run. The pitch fraction represents a certain amount of vertical rise over the entire span. Although most homeowners do not need to measure pitch it still pays to understand this term.

First measure 12 inches from one end of the level and make a mark. For example given a roof with a rise of 4 feet and a span of 24 feet the pitch is 1 to 6 pitch which can be expressed as the fraction of 1 6. Pitch is thus the ratio of the rise in inches to a 12 inch run and is often expressed using a semicolon for example 6 12. Roof pitch is the measurement of the angle or the steepness of your roof.

A proper roof pitch is important for maximizing the effectiveness of your roof. The roof pitching is essentially how steep the roof is going to be they are either going to be flat or pitched.
