Winter is still upon us and the threat of ice and snow damage can take its toll on your home or business.
As temperatures rise and snow begins to melt, so does the probability of damage in your home or business due to snow melt, ice damming, and leaking roofs. This especially becomes a problem when it is warm during the day, then freezing cold at night.
Ice dams form when the snow melts on an upper, warmer part of a roof. Liquid then runs down the roof toward the colder eave, where it freezes into ice. As the ice accumulates, it can back up under the roof shingles, where it melts again, soaking the roof sheathing and leaking into the attic. There, it soaks the insulation and can leak through the ceiling drywall and often down the walls into your living space. When large ice dams form, they can be very heavy and can damage gutters, soffits, and even present a safety hazard to people below.

Preventive tips from the pros at Advanced Disaster Recovery Inc:
Use a roof rake during heavy snow: Ice dams happen quickly after a heavy snow because of the insulating properties of snow. Removing at least the lower 4 feet of snow from the roof edge, using a roof rake, can help prevent ice dams from forming. A roof rake is like a shovel that is turned on its side and has a very long handle, allowing you to pull snow off the roof while on the ground safely. Never get onto a roof to remove snow.
If you have an ice dam forming, you can apply an ice melt like rock salt or calcium chloride.
The most effective long-term solutions for ice dams are to keep heat out of the attic and to promote ventilation under the roof deck to keep it as cold as possible. The underside of the roof deck must be a similar temperature to the exterior side of the roof.
Ideally, ventilation provides for continuous airflow from the soffit (the underside of the roof eaves) to the peak, or ridge, of the roof. A soffit-and-ridge vent system usually requires insulation baffles installed at the lower side of the roof, above the exterior walls. The baffles hold back the insulation by a couple of inches, creating a channel for air to flow freely past the insulation.
If a soffit-and-ridge system is not feasible or desirable, ventilation can be provided with soffit or gable vents for intake air and several conventional roof vents for exhaust air. As a general guideline, ventilation systems should provide 1 square foot of net free ventilation per 150 square feet of attic floor space. Net free ventilation is the total area of openings in a vent, minus all screening or other obstructions.
