Leaving the snow on your roof should not be an option. As the warm air in your house or commercial building rises, it will melt the snow on the roof. As it melts, water will take the path of least resistance, which often means traveling up under your shingles, or making its way through bad seams which will immediately cause leaks.
DO NOT try to remove snow or ice from your roofing with rock salt or calcium. Chances are it will do more damage to your roof material than it will good.
Even if you took the proper steps this fall and prepared your roofing for winter by inspecting flashing, cleaning gutters, and ensuring proper attic ventilation, the risk of leaving snow on your roof is still great. In the battle of water vs. your construction, the water will often win. Snow removal is relatively inexpensive when compared to the price of roofing repair.
When hiring a roofer to remove snow, it is important to ask two questions up front so you know what the job will cost.
1) Is snow removal from the roof an hourly job or do you pay per visit? You do not want to get stuck with a hefty bill that you were not expecting.
2) Does the roofer have workman's compensation and liability insurance? Snow removal and winter conditions make for dangerous conditions. Don't hire a cheap unprofessional roofer that could end up causing you problems and even lawsuits if there is an accident.
