The incline or pitch of a roof can be easily measured with a level, tape measure, and a pencil.

How to measure a roof pitch. The pitch of a roof, or roof slope, helps determine how quickly excess water, snowfall, or debris will fall off of the 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. Roof pitch = 1 ÷ tangent (rise ÷ run) how to calculate roof pitch as a ratio.

Extend it upward so it is perpendicular to the level. Note the vertical distance on the tape measure and write this value down. Measure the vertical distance from roof to level.

You will want to make sure you are measuring straight so it may be helpful to use a long level like this (link to amazon). This is simple to do, and you’ll need the same tools. If this distance measures 4 inches, you have a 4 in 12 pitch;

A roof's pitch is the rise for every 12 inches it runs.

The roof pitch is measured by how much the roof slants upwards. Sometimes you might even measure the ‘span’, which refers to the. The next step is to measure the pitch (also referred to as the roof slope) of the roof deck.

At the time that you’re computing the roof pitch of your house, you’re computing the ‘run’, as well as the ‘rise’. Find the inverse tangent of the pitch to find the angle in degrees. Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run.

A 4/12 roof pitch is referred to as the roof rises 4 inches in height for every 12 inches, as it measured horizontally from the edge of the roof to the centerline. Then mark height on vertical level to roof surface, remove levels and measure marked height. Keeping the level balanced measure the distance from the level to the roof surface.if a roof has many layers of shingles your measurement could be slightly inaccurate using this method

The roof’s pitch is the number of inches the roof rises in 12 inches.
