15 Degree Roof Pitch Options

Steeper slopes increase the sail effect that makes them susceptible to wind.

15 degree roof pitch options.

To put it in perspective the angle of this slope would be around 30 degrees. A 12 12 pitch roof has a pitch angle of 45. Other than the 45 roof slope which is 12 in 12 none of the standard roof pitches 5 in 12 6 in 12 etc are equal to a whole degree. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.

The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. 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.

But with the use of a roof pitch in degrees converter you will be able to get the correct measurement. Divide the first part of the ratio by 12 to work out the pitch. With the use of this converter it will be easier for you to locate a 30 degree roof pitch 20 degree roof pitch 25 degree roof pitch or a 15 degree roof pitch. The slope of a roof or pitch is determined by how many inches the roof rises over 1 foot or 12 inches.

An example for a steep sloped roof is 8 12. On blue prints architects engineers usually display the pitch of a roof in the format shown on the image where number 4 represents a rise and number 12 represents a length. This means that the rise of the slope goes up or down 8 inches for every 12 inches. The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7.

What degree angle is a 12 12 pitch roof. A pitch over 9 12 is considered a steep slope roof between 2 12 and 4 12 is considered a low slope roof and less than 2 12 is considered a flat roof. Find the inverse tangent of the pitch to find the angle in degrees. To convert between american roofing ratios and pitch degrees follow these steps.

The table below shows common roof pitches and the equivalent grade degrees and radians for each. Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. A 30 degree roof slope 7 12 pitch is the right pitch to aerodynamically handle high wind.
