2 12 Roof Angle

Roof pitch calculator results explained.

2 12 roof angle.

Conventional roofs are the easiest to construct and you can walk on them safely. A 2 12 roof slope means your roof has 2 inches of vertical drop for every 12 inches of horizontal distance. These roofs have a pitch less than 4 12. Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof.

Most roof s have a pitch in the 4 12 to 9 12 range. 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. So use the 12 inch level as a constant run and 18 inch ruler as a variable rise. Find the inverse tangent of the pitch to find the angle in degrees.

2 12 roof pitch angle 9 46 degrees. 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. Find all the needed factors in order to determine the pitch angle s degree. Definitions vary on when a roof is considered pitched.

Generally such roofs have a pitch ranging from 1 2 12 to 2 12. They have a pitch ranging from 4 12 to 9 12. Enter any pitch or fraction of pitch to find angle. Locate its tangent or tan and follow the left row for you to read its corresponding degree.

The exact roof slope in degrees is given by the arctangent. 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. A 12 12 pitch roof has a pitch angle of 45. 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.

Angle the angle of a roof is the same as the roof s slope except instead of being. To convert between american roofing ratios and pitch degrees follow these steps. Simply put it s a shallow roof. Low pitched roofs are generally difficult to maintain and you need special materials to prevent leaks.

This is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations. In degrees 10 2 in 12 or 1 in 6 is considered a minimum. The combination of two numbers are used to display or show the roof pitch. The 12 inch run is considered standard in roof pitch or angle terminologies.

Divide the first part of the ratio by 12 to work out the pitch.
