Roof pitches can be as high as 12 12 according to the mhimperialhome website.
Ranch roof 7 12 roof pitch.
This can be very effective for certain ranch styles porch rooftops or modern geometric rooftops.
7 12 roof pitch 7 on 12 roof pitch 7 12 roof slope.
Pitches above 9 12 are very highly angled and are designated steep slope roofs.
Pitches of less than 2 12 are considered flat roofs even though they may be very slightly angled.
Hipped roofs are also common which offer a slightly different design and lower pitch.
Plus since the low pitch requires fewer materials and less work than the steep pitch it comes at a lower cost.
The table below shows common roof pitches and the equivalent grade degrees and radians for each.
A 30 degree roof slope 7 12 pitch is the right pitch to aerodynamically handle high wind.
7 12 roof pitch equivalents roof rises 7 in a length of 12.
We included a roof pitch chart below the 7 12 example image and the calculator below that.
Roof pitch degree table.
The most commonly used roof pitches fall in a range between 4 12 and 9 12.
Lower slopes don t handle wind driven rain as well.
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.

8 12 roof pitch 33 angle 33 69 degrees details 9 12 roof pitch 37 angle 36 37 degrees details.
The 30 degree 7 12 roof recommendation is backed up by testing according to the publication science daily.
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.
If this isn t practical then perform the same measurement on the underside of the roof.
Gable roofs offer the advantages of easily shedding rain and snow in cold climates.
Picking a low pitch or slope for your roof will give your rooftop a flatter more box like look.

Steeper slopes increase the sail effect that makes them susceptible to wind.
