It may be possible to remove the snow and ice from your sloped roof using a roof rake – a long-handled tool designed specifically for this purpose. Stand on the ground and pull as much of the snow off the eaves as you can safely reach.
If you cannot safely reach the roof, contact a homebuilder, landscaping and roofing contractor, or property maintenance company to remove the snow and ice. Before hiring a contractor, check their references. Always be sure any contractor you hire is qualified, insured and bonded.
The amount of snow and ice your roof can support will depend on a number of factors, including the roof type as well as the age and condition of the structure. But a good rule to keep in mind is if more than a foot of heavy, wet snow and ice has accumulated on your roof, you should have it removed.
