Recalculate this value into an angle.

How to measure the angle of my roof.

The angle of your roof is calculated the same way you d work the angle of a right angled triangle. For many people working out the roof pitch angles can be a bit of a nightmare especially if you are going to do it yourself and try to manage it all on your own. Naturally this does not go down particularly well without the right tools knowledge and assistance. Outline the roof at the points that are on the same level or elevation to ensure that you re getting an accurate calculation of your roofing measurements.

Total height of building. First convert the pitch to a slope. Then enter the value of the run and choose the unit of measurement from the drop down menu. Rise run rise run slope.

For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches. Rafter height width from pythagoras remember that at school so. If you prefer to work the angle out the traditional way without our handy calculator you can use the following equations to find the length of the rafter and the slope. Pitch rise run 1 5 6 25.

Angle the angle of a roof is the same as the roof s slope except instead of being represented as x 12 it is represented in degrees. To find the angle of a roof in degrees convert the pitch to a slope then convert to degrees by finding the arc tangent of the slope. Enter any pitch or fraction of pitch to find angle. This is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations.

Determine the vertical height between the base of the roof and the highest point. Thus in a simple style house you ll only have to click on the corners. Enter any angle or fraction of angle to find pitch. To do this simply convert the rise and run as a fraction to a decimal form eg.

Rafter rise run 1 5 6 2 25 36 38 25rafter 38 25 6 18 m. Determine the distance from the edge of the roof to a point on the same plane directly under the highest point. How to figure roof angles 1. 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.

Calculate the roof pitch as the proportion of rise and run. Finally you can find the roof pitch in the form of x 12. First enter the value of the rise and choose the unit of measurement from the drop down menu. Angle arctan pitch arctan 0 25 14.

This is useful because sometime you may need to cut a bevel with your circular saw that is not calibrated using roof pitch style this setting on circular saws is calibrated in degrees. If you were to click on the peaks it wouldn t give you an accurate reading of your measurement. Outside of the u s a degree angle is typically used. Calculate the tangent of the roof angle by.
