2 12 Roof Angle

Conventional roofs are the easiest to construct and you can walk on them safely.
2 12 roof angle. A 2 12 roof slope means your roof has 2 inches of vertical drop for every 12 inches of horizontal distance. They have a pitch ranging from 4 12 to 9 12. Find all the needed factors in order to determine the pitch angle s degree. Divide the first part of the ratio by 12 to work out the pitch.
Angle the angle of a roof is the same as the roof s slope except instead of being. 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. 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.
The 12 inch run is considered standard in roof pitch or angle terminologies. In degrees 10 2 in 12 or 1 in 6 is considered a minimum. Low pitched roofs are generally difficult to maintain and you need special materials to prevent leaks. Locate its tangent or tan and follow the left row for you to read its corresponding degree.
Simply put it s a shallow roof. To convert between american roofing ratios and pitch degrees follow these steps. Find the inverse tangent of the pitch to find the angle in degrees. 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. Most roof s have a pitch in the 4 12 to 9 12 range. So use the 12 inch level as a constant run and 18 inch ruler as a variable rise. 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.
Definitions vary on when a roof is considered pitched. Common roof pitches and equivalent grade degree and radian angles. Roof pitch calculator results explained. 2 12 roof pitch angle 9 46 degrees.
The exact roof slope in degrees is given by the arctangent. Generally such roofs have a pitch ranging from 1 2 12 to 2 12. These roofs have a pitch less than 4 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.
The combination of two numbers are used to display or show the roof pitch.
