How To Measure The Angle Of My Roof

Here are the steps to follow for the roof angle calculator.

How to measure the angle of my 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. Total height of building. The angle of your roof is calculated the same way you d work the angle of a right angled triangle. First convert the pitch to a slope.

Determine the vertical height between the base of the roof and the highest point. 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. If you were to click on the peaks it wouldn t give you an accurate reading of your measurement. Finally enter the value of the rafter length and.

Thus in a simple style house you ll only have to click on the corners. Naturally this does not go down particularly well without the right tools knowledge and assistance. Then enter the value of the run and choose the unit of measurement from the drop down menu. Calculate the roof pitch as the proportion of rise and run.

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. Outside of the u s a degree angle is typically used. For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches. Finally you can find the roof pitch in the form of x 12.

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. 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. 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.

Pitch rise run 1 5 6 25. Rise run rise run slope. Determine the distance from the edge of the roof to a point on the same plane directly under the highest point. Enter any pitch or fraction of pitch to find angle.

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. Recalculate this value into an angle. First enter the value of the rise and choose the unit of measurement from the drop down menu. Enter any angle or fraction of angle to find pitch.

This can be read from the. This is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations. 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. Angle arctan pitch arctan 0 25 14.
