While snow-covered roofs can make for a picturesque winter scene, the combination of freshly fallen snow with the melting and refreezing of snow can place stress on the roof of your home or business. If more than a foot of heavy, wet snow and ice have accumulated on the roof, you should have it removed.
Snow Removal Tips
Clearing the snow off your roof from the gutters or eaves upwards of three to four feet after each winter storm can help prevent ice dams from forming. Remember to avoid using a ladder in snowy and icy conditions. This can be extremely dangerous and is best left to professionals.
For Flat Roofs:
If your flat roof is easily accessible from an interior stairway, you may want to shovel the roof, but be careful not to damage the roof covering.
Remember to put safety first any time you are on a roof, especially one that is covered in snow and ice. If you have any doubt, leave it to professionals.
For Sloped Roofs:
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.
