Snow on a pitched roof.

Metal roofing system when properly designed and installed is famous for its strong performance against harsh climate environments. First figure out how deep the snow is piled up there. If your roof is pitched enter the length and width of the flat area covered by the roof. The steeper the pitch the better the snow will fall to the ground.

Flat roofs can be significantly cheaper to install than a pitched roof but they will often require more maintenance. The exact roof slope in degrees is given by the arctangent. Neither of these are accurate. It also helps if the roof is in a sheltered area.

If your roof is flat it is more likely to have snow load problems than if it is pitched. The snow settles on it. Low pitch roofs are seldom used in regions of severe weather due to the stress of snow accumulation on roofs of structures. The ideal pitched roof is smooth and steep so the snow slides off and framed with closely spaced rafters for strength.

Definitions vary on when a roof is considered pitched. Here at pro roofers we specialize in flat roof installation and maintenance and over the years we have gathered a wealth of expertise concerning flat roofs so let s set the record straight.

The easiest way is to push a yardstick into the snow on the roof selecting an area that looks typical of the overall snow depth.

Minimum pitch metal roof snow. In degrees 10 2 in 12 or 1 in 6 is considered a minimum. There are several other factors that add up to this quality certainly such as proper slope snow loading requirements or the snow guard usage. You need to use a snow load formula for flat roofs.

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. Slate is also a popular.
