60 Degree Roof Pitch

8 12 pitch 33 75 degrees.

60 degree roof pitch. 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 following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. Steeper slopes increase the sail effect that makes them susceptible to wind. 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.

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. In snowy areas your roof should be at least 10 12 40 to allow snow to shed while the safest roof pitch in very windy areas is between 4 12 6 12 18 5 26 5. 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.

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. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. A 30 degree roof slope 7 12 pitch is the right pitch to aerodynamically handle high wind. 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.

Look at the column labeled pitch then look under degrees to get the corresponding amount of degrees. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. Lower slopes don t handle wind driven rain as well. For a gothic style the rafters must equal the span 60 while an elizabethan style requires the rafters to be longer than the span.

The 30 degree 7 12 roof recommendation is backed up by testing according to the publication science daily. The roof pitch calculator is a convenient online tool you can use to quickly assess the pitch of your roof to determine the length of rafters you need. Roof pitch calculator results explained. You have to pay higher cost for steeper pitch.

Other than the 45 roof slope which is 12 in 12 none of the standard roof pitches 5 in 12 6 in 12 etc are equal to a whole degree. The table below shows common roof pitches and the equivalent grade degrees and radians for each.
