How to Run a Heater in the Attic to Melt Snow on the Roof

Running a heater in the attic of your home helps to melt accumulating snow on your roof more quickly. This, in turn, eliminates any potential structural and roof damage from the weight of the precipitation. Operating the heater is advisable only if you follow the instructions carefully to prevent a fire hazard. Another problem that often results from heater use is ice dams, particularly if the temperatures are extremely cold.

Instructions

- 1
  Install a heater that is vented to the outdoors if possible. This prevents problems with water vapor buildup from unvented heating appliances.
- 2
  Place heaters away from combustible materials and where they will not fall over accidentally, which can cause a fire.
- 3
  Run an unvented heater only as long as the owner's manual states. These types of heaters are often not appropriate for long-term use.
- 4
  Open a window in the attic a couple of inches when using an unvented heater. This allows excess moisture and combustion pollutants to seep out the window, rather than remaining in your home.
- 5
  Inspect the roof overhangs for ice dam formations periodically during extreme cold weather. If you spot any ice beginning to form, shut off the heater. It is best for the attic temperature to be below freezing once the outdoor temperatures dips below 20 degrees, State Farm advises. This prevents the ice dam from getting larger and causing water damage.
