How to find the angle of a roof.

Roof pitch is a determining factor for cost of the roof as well as the roof area and the type of materials used. Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. If you want to know how to find the pitch of a roof then start with a calculator. Rise run rise run slope.

Divide the first part of the ratio by 12 to work out the pitch. For a pitch expressed in inches per foot convert to a fraction. So use a tape measure to find the height of the roof above the top wall of the building. Outside of the u s a degree angle is typically used.

With the help of these roof pitch degree calculator programs you can make sure that your home is nice and balanced. 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. 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.

Although there s isn t any standard pitch of a roof used on all kinds of sloped roofs you can determine the range of pitches by using a roof angle calculator and by considering factors like the local climate and roofing materials. The number of inches that the roof rises vertically for every foot of roof. It always makes sense to the standard roof pitch angle spot on as the benefits of doing so are quite obvious. Find the inverse tangent of the pitch to find the angle in degrees.

The angle of your roof is calculated the same way you d work the angle of a right angled triangle. The pitch of the roof is a ratio. 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. For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches.

This is a way of measuring the degree of steepness of the roof. Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run. A 12 12 pitch roof has a pitch angle of 45.
