2 12 Roof Angle

Roof pitch calculator results explained.

2 12 roof angle.

These roofs have a pitch less than 4 12. Angle the angle of a roof is the same as the roof s slope except instead of being. They have a pitch ranging from 4 12 to 9 12. Definitions vary on when a roof is considered pitched.

Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof. Generally such roofs have a pitch ranging from 1 2 12 to 2 12. A 2 12 roof slope means your roof has 2 inches of vertical drop for every 12 inches of horizontal distance. If a roof rises 2 in a length of 12 this is 2 12 roof pitch.

2 12 roof pitch angle 9 46 degrees. 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. Divide the first part of the ratio by 12 to work out the pitch. The exact roof slope in degrees is given by the arctangent.

Enter any pitch or fraction of pitch to find angle. To convert between american roofing ratios and pitch degrees follow these steps. In degrees 10 2 in 12 or 1 in 6 is considered a minimum. 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.

Find all the needed factors in order to determine the pitch angle s degree. A 12 12 pitch roof has a pitch angle of 45. The 12 inch run is considered standard in roof pitch or angle terminologies. So use the 12 inch level as a constant run and 18 inch ruler as a variable rise.

Simply put it s a shallow roof. 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. Low pitched roofs are generally difficult to maintain and you need special materials to prevent leaks. Find the inverse tangent of the pitch to find the angle in 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. Most roof s have a pitch in the 4 12 to 9 12 range. 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. The combination of two numbers are used to display or show the roof pitch.

Common roof pitches and equivalent grade degree and radian angles.
