How To Work Out The Pitch Of A New Roof

If you are trying to learn how to measure roof pitch calculations accurately you should really consider the importance of using a calculator.

How to work out the pitch of a new roof.

The next step is to punch in 1 whatever your tangent is to find the angle of your roof pitch. One method to find the pitch is to climb on the roof and measure the rise for a 12 run. If you are trying hard to work out how to figure roof pitch measurements the calculator takes away all of those problems for you more or less instantly. Divide the first part of the ratio by 12 to work out the pitch.

A 12 12 pitch roof has a pitch angle of 45. For a roof with the ridge above one wall the span is the same as the run. Pitch is the incline of the roof represented as the ratio of rise to the span twice the run. Divide the slope by two to get the pitch.

You ll need a level that is 12 or longer and a tape measure. Find the inverse tangent of the pitch to find the angle in degrees. For a simple gable roof the span wall to wall will be twice the size of the run wall to ridge horizontally. The roof pitch measures the steepness of your shed roof and typically takes values from 1 to 12.

As aforementioned there is no standard pitch of a roof. This free roof pitch calculator will take your roof width see the picture and rise the height of the roof and will calculate the roof pitch both as numeric value. If your roof pitch is greater than 3 your roof is considered pitched read more about roof pitch at wikipedia. Once you have these two measurements you ll need to grab hold of a calculator and divide the rise by the run to work out the tangent.

On the roof hold the level perfectly level and measure the height from the roof to the level 12 inches away from where the level touches the surface this will be the rise. Here are a couple examples. To convert between american roofing ratios and pitch degrees follow these steps.
