The key factors are usually snow loading requirements adequate slope and the use of snow guards when needed.
Roofs with valleys dormers and other obstructions causes snow on metal roofs to building up erratically.
In some cases roof snow melt systems or heat tape can be used to combat ice accumulation on eaves and in valleys.
The slope of the roof is also extremely important.
I m looking at lining a section 3m x 6m some roof some external walls and an internal wall for a bar and doing my home brew.
Shed dormers are easier to waterproof and shed snow better than gable dormers.
If these issues are addressed during the design stage and the roofing contractor does his job these systems will almost always perform as intended.
Valleys are always lined with ice membrane three feet each side.
To complete this roof system snow stops or snow brackets are used to stop all snow movement.
They then have the option of putting dormers on the roof without damage to the valleys penetrations lower roofs and property below due to sliding snow and ice.

Simple gable roofs shed snow and ice more quickly than complicated rooflines.
This allows the snow to stay on while venting the roof system.
At present everything is all over the floor.
Iko recommends that you install architectural shingles with the open valley method for the best roof performance.
I would like to have a nice workshop.
Most roofs are engineered to hold the snow.
