Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. The triangle diagram will be re drawn to scale with all dimensions marked. With a mobile device a button will appear. 45 this is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations.

This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. Tap the button to start measuring and lay your device on an angle roof to measure pitch and angle and animate the diagram. Lower slopes don t handle wind driven rain as well. What degree angle is a 12 12 pitch roof.

Find the inverse tangent of the pitch to find the angle in degrees. Angle the angle of a roof is the same as the roof s slope except instead of being. 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.

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. Enter any angle or fraction of angle to find 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. Visit this page on your phone to directly measure pitch and angles.

Divide the first part of the ratio by 12 to work out the pitch. A 30 degree roof slope 7 12 pitch is the right pitch to aerodynamically handle high wind. Roof pitch calculator results explained. 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.

Enter any pitch or fraction of pitch to find angle. Most roof s have a pitch in the 4 12 to 9 12 range. Steeper slopes increase the sail effect that makes them susceptible to wind. Roof angles and rafter plumb cuts.

The 30 degree 7 12 roof recommendation is backed up by testing according to the publication science daily. Enter run the flat level length then click pitch angle or rise to select then enter other known dimension angle or pitch. Common roof pitches and equivalent grade degree and radian angles. However if you to do the process using your own knowledge you can still convert pitch to degrees by dividing the rise and run and get its corresponding measurement.
