Roof slope 30 degrees.
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 30 degree 7 12 roof recommendation is backed up by testing according to the publication science daily.
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.
The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72.
45 this is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations.
The following table shows how the same common roof slopes can be expressed using rise in run ratios degrees and percentages.
This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
It s just a little math.
Another option that is available for you in finding the pitch factor for your roof is to find roof pitch calculator online.
Lower slopes don t handle wind driven rain as well.
The table below shows common roof pitches and the equivalent grade degrees and radians for each.
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.
Also see our page quick reference.
Enter any pitch or fraction of pitch to find angle.
The minimum roof pitch for shedding snow is around 30 or a 6 12 or 7 12 slope although this is not a definite as the material of your roof the direction of the snow and wind are some factors that can affect whether or not snow will slide as roofs of as little as 10 have been reported to shed snow.
Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio.
Enter any angle or fraction of angle to find pitch.
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.
Degrees to roof pitch rise in run to see a table.
Steeper slopes increase the sail effect that makes them susceptible to wind.
See below after the table for directions on how to convert any roof slope from one form to another even roof slopes not shown in the table.
A 30 degree roof slope 7 12 pitch is the right pitch to aerodynamically handle high wind.
