The following table shows how the same common roof slopes can be expressed using rise in run ratios degrees and percentages.
Roof slope 10 degrees.
I am a main contractor doing an extension on which an architect has designed a 10 degree lean to pitch roof.
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.
Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio.
I agree with him and trust.
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.
This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
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.
Degrees to roof pitch rise in run to see a table.
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.
10 on 12 roof pitch 10 12 roof pitch 10 12 roof slope measure roof pitch.
Select the best roof trusses and budget amount.
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.
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.
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.
10 12 roof pitch to angle 39 81 degrees equivalents.
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.
The pros and cons of aluminum roofing.
The table below shows common roof pitches and the equivalent grade degrees and radians for each.
Although there s isn t any standard pitch of a roof used on all kinds of sloped roofs you can determine the range of pitches by using a roof angle calculator and by considering factors like the local climate and roofing materials.

The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72.
My roofer is adamant it will leak even if we use forticrete centurion tiles which go down to 10 degrees at a push.
