2 12 Roof Angle

The 12 inch run is considered standard in roof pitch or angle terminologies.

2 12 roof angle.

A 12 12 pitch roof has a pitch angle of 45. Definitions vary on when a roof is considered pitched. The combination of two numbers are used to display or show the roof pitch. In degrees 10 2 in 12 or 1 in 6 is considered a minimum.

So use the 12 inch level as a constant run and 18 inch ruler as a variable rise. Find all the needed factors in order to determine the pitch angle s degree. Locate its tangent or tan and follow the left row for you to read its corresponding degree. To convert between american roofing ratios and pitch degrees follow these steps.

Most roof s have a pitch in the 4 12 to 9 12 range. 2 12 roof pitch angle 9 46 degrees. Simply put it s a shallow roof. These roofs have a pitch less than 4 12.

Generally such roofs have a pitch ranging from 1 2 12 to 2 12. Enter any pitch or fraction of pitch to find angle. 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. Conventional roofs are the easiest to construct and you can walk on them safely.

Low pitched roofs are generally difficult to maintain and you need special materials to prevent leaks. If a roof rises 2 in a length of 12 this is 2 12 roof pitch. 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. Angle the angle of a roof is the same as the roof s slope except instead of being.

This is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations. That means the roof doesn t shed water as easily as steeper roofs which is why choosing the right type of roofing material is so important. Common roof pitches and equivalent grade degree and radian angles. 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.

Roof pitch calculator results explained. The exact roof slope in degrees is given by the arctangent. They have a pitch ranging from 4 12 to 9 12. Find the inverse tangent of the pitch to find the angle in degrees.

A 2 12 roof slope means your roof has 2 inches of vertical drop for every 12 inches of horizontal distance.
