How To Measure The Angle Of A Roof

First enter the value of the rise and choose the unit of measurement from the drop down menu.

How to measure the angle of a roof.

Thus in a simple style house you ll only have to click on the corners. The angle of your roof is calculated the same way you d work the angle of a right angled triangle. Gable roof pitch can also be given as ration described as the rise over the run. Then enter the value of the run and choose the unit of measurement from the drop down menu.

Pitch of any roof can be computed by the number of inches it grows vertically for every 12 inches it extends horizontally. 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. 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. However carpenters typically make use of diverse finders of roof pitch angles an example of that is being a rafter.

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. Finally enter the value of the rafter length and. Outside of the u s a degree angle is typically used. Let s assume it is equal to 6 m.

For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches. How to figure roof angles 1. 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. If you were to click on the peaks it wouldn t give you an accurate reading of your measurement.

Roof slope calculator example of use. This can be read from the. For example a roof that rises 6 inches for every 12 inches of the horizontal run has a 6 in 12 pitch. Calculate the tangent of the roof angle by.

Determine the vertical height between the base of the roof and the highest point. Let s say it is equal to 1 5 m. Rafter height width from pythagoras remember that at school so. Determine the distance from the edge of the roof to a point on the same plane directly under the highest point.

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. Calculate the rafter length substituting these values. Measure the rise of your roof. Measure the run length it is the horizontal distance between the roof ridge and the wall of the building.
