How to you find the slope of a roof.

There are also a number of smartphone apps that you can use to find the slope of your roof if you have a clear view of a gable end on the building. Just write down the measurements you found. Another way of stating this is that the roof has a rise of 5 and a run of 12. It can be assessed in two ways either as the angle the rafter makes with the horizontal or the proportion between the rise and the run of the roof.

Rise run rise run slope. The slope of your roof is the ratio of vertical distance rise to horizontal distance run. Measuring the underside of the roof is actually the most accurate way of calculating the slope of the roof as there are no materials which will create an uneven surface. Here are the steps to follow for the roof angle calculator.

Assuming the roof to be a right triangle the slope of the roof will be measured as the ratio between bd and dc. You can measure with twelve feet or twelve yards but in this article we will use twelve inches. Then enter the value of the run and choose the unit of measurement from the drop down menu. 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.

Go search your app store for roof pitch apps. Roof slopes are measured in units of twelves. Roof pitch is simply the slopecreated by the rafter. First enter the value of the rise and choose the unit of measurement from the drop down menu.

There s no need to simplify them. The slope of a roof. For example when a roof has a slope of 5 12 the roof is 5 inches high for every 12 inches long. Finally enter the value of the rafter length and.

You don t have to get up on the roof or go to the attic to use these. To do this simply convert the rise and run as a fraction to a decimal form eg. These can be acceptably accurate sometimes. 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.
