The table below shows common roof pitches and the equivalent grade degrees and radians for each.
10 deg pitch roof.
The planum roof tiles can be used on pitches as low as 10 degrees thanks to the innovative design and the highly engineered manufacturing process.
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.
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.
Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio.
This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
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 triangle diagram will be re drawn to scale with all dimensions marked.
I am a main contractor doing an extension on which an architect has designed a 10 degree lean to pitch roof.
Drag sliders to animate the results and diagram.
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.
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 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.
I have never been keen on such a shallow pitch especially with velux in.
I agree with him and trust.
10 degree pitch roof.
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.
As one of the leading low pitch roof tiles on the market the planum comes in a range of 5 colours.
This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
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.
