Any pitch higher than 9 12 is considered a steep pitch.
Steep pitch roof for snow.
Even without a cold roof system a steep roof is generally better in a snowy environment which is why you see those dramatic a frame homes in colder areas.
Suitable materials for pitched roofs.
But without designing the snow retention based on accurate testing you could be wishing you had that steep slope and metal roof which was always intended to shed snow.
Ice melts more easily on a steep slope preventing the build up of ice patches or dams that can force.
A flat roof would have a 2 12 pitch while the average roof pitch would be between 4 12 and 9 12.
How to work on a steep roof the benefits of pitched roofs.
Otherwise it would settle in a puddle.
Pitched roofs are there for a reason they help the flow of rainwater and even snow to move away from the roof.
They encourage snow to slide off before it builds up too high.
If every roof was flat there d be a lot more leaks and water damage.
Over time these puddles can cause rot mildew and other issues.
Pitched roofs begin with with slopes greater than 3 in 12.
This gets rid of moisture quicker and avoids weight issues with piled up snow and ice especially in areas with a lot of precipitation.
The 45 degree roofs seen on a frame houses are 12 in 12 but roofs can be even steeper consider the mansard roofs introduced by french second empire architects in the middle of the 1800s.
