In the north, snow load compliance isn’t optional—it’s a legal and structural necessity.
According to the Ontario Building Code, roofs must support specific snow weight based on your zone.
In Sudbury, that means your prefab’s roof should be able to handle 50+ pounds per square foot.
Prefab models are built in factory settings, allowing for precision engineering that ensures:
Roofs meet or exceed snow load standards.
Rafters and trusses are spaced for optimal strength.
Roof pitches are steep enough (often 4:12 or greater) to shed snow naturally.
Many small prefab models even come with metal roofing options, which not only boost durability but also reduce energy consumption by reflecting sunlight and preventing heat loss.
