If this isn t practical then perform the same measurement on the underside of the roof.
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.
Gable roofs on ranch style homes can have a variety of pitches from low to steep.
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.
The table below shows common roof pitches and the equivalent grade degrees and radians for each.
The 30 degree 7 12 roof recommendation is backed up by testing according to the publication science daily.
Pitches lower than 4 12 have a slight angle and they are defined as low slope roofs.
Gable roofs offer the advantages of easily shedding rain and snow in cold climates.
Lower slopes don t handle wind driven rain as well.
A 30 degree roof slope 7 12 pitch is the right pitch to aerodynamically handle high wind.
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.

Pitches above 9 12 are very highly angled and are designated steep slope roofs.
We included a roof pitch chart below the 7 12 example image and the calculator below that.
