How to measure roof pitch uk.

If you have an iphone or an android device there are a great number of free roof pitch calculator uk apps available that use the phone s internal gyroscope to measure your pitch roof angle. First measure 12 inches from one end of the level and make a mark. Move the tape measure along the the roof until it hits the level at exactly the 12 inch mark. Finally enter the value of the rafter length and.

If you are trying to learn how to measure roof pitch calculations accurately you should really consider the importance of using a calculator. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. See the image below for more explanation on rise run and pitch. Pitch is the incline of the roof represented as the ratio of rise to the span twice the run.

A 12 in 12 pitch is a steep 45 degree angle roof. Pitch rise run 1 5 6 25. Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run. It is often compared to slope but is not exactly the same.

Calculate the roof pitch as the proportion of rise and run. Hold the 0 mark of the tape measure against the roof. First enter the value of the rise and choose the unit of measurement from the drop down menu. Finally you can find the roof pitch in the form of x 12.

Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level. Note the vertical distance on the tape measure and write this value down. Extend it upward so it is perpendicular to the level. Here are the steps to follow for the roof angle calculator.

To measure the roof pitch you ll need an 18 or 24 inch level a tape measure and a pencil. Here s an easy safe way to determine the pitch from inside your attic. Measure the vertical distance from roof to level. Then enter the value of the run and choose the unit of measurement from the drop down menu.

Rafter rise run 1 5 6 2 25 36 38 25rafter 38 25 6 18 m. Recalculate this value into an angle. Angle arctan pitch arctan 0 25 14. 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.

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.
