First convert the pitch to a slope. Find the inverse tangent of the pitch to find the angle in degrees. Marvel at your mathematical. Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run.

To convert between american roofing ratios and pitch degrees follow these steps. Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level. A roof slope of 4 12 is a 1 6 pitch a 6 12 slope is a 1 4 pitch an 8 12 slope is a 1 3 pitch and so on. 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.

If a magazine such as finehomebuilding is going to put out an article to teach a topic it should use the proper words and definitions. To do this simply convert the rise and run as a fraction to a decimal form eg. Check your results with the omni roof pitch calculator.
