How To Find Roof Slope

If you want to find the roof pitch in the form of x 12 simply calculate the pitch and substitute 12 for the run length.

How to find roof slope.

Let s assume it is equal to 6 m. The roof pitch is important in determining the appropriate installation method and how much roofing material will be needed. The value displayed as the rise will be your x. Slope the slope of a roof is represented as x 12 where x is the number of inches in rise for every 12 inches of run this is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares.

If it doesn t have this mark use a tape measure to locate. For example if you find 4 inches of height with the tape measure at the 12 inch mark on the level your slope is 4 12 or 4 in 12. What is the roof pitch. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.

It is often compared to slope but is not exactly the same. Use a level against the underside of the rafter you re measuring to get the most accurate value. Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run. Even if you want to use a flat roof pitch calculator system you will be able to find one.

For instance a 7 12 roof pitch means that the roof rises 7 inches. Locate the level s 12 inch mark. Homes and other buildings have roofs with slopes ranging from no slope or flat to very steep slopes. Roof pitch is used to describe the slope or angle of the roof.

To accurately calculate the area of your roof you must first determine its slope or pitch. The rise is the height of the roof and the run is the horizontal span as pictured above. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. Roof pitch calculator results explained.

Roof slope calculator example of use. The roof pitch is the slope of the rafter. How to calculate the pitch of a roof. Just write down the measurements you found.

How roof pitch is calculated. The most precise way to find the roof s slope is by measuring it from the underside. Access one of the rafters then take the measurement this way. For example if a roof has a pitch of 4 12 then for every 12 inches the building extends horizontally it rises 4 inches.

This will allow your project to carry the depth and detail in the roof that you wanted as well as make sure that it will maintain a sturdy and effective nature throughout. If you want to know how to find the pitch of a roof then start with a calculator. The pitch is commonly defined as the ratio of rise over run in the form of x 12. 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.

The slope of your roof is the ratio of vertical distance rise to horizontal distance run.
