We haven't yet seen the worst of the interior water damage we expect from this unusually severe winter. You might still have time to take action to prevent or reduce damage.
Ice dams form from heat escaping through the roof and melting the snow that's piled up. Water then runs down the roof. As it hits the edge of the roof where there is no heat rising from below, it freezes and forms an ice dam along the edge of the roof. If you see icicles hanging off your roof or gutters, chances are you are in for trouble.
This time of year, when daytime temperatures tend to be above freezing, even more snow melt starts to happen. If the ice dam keeps the water from running off the roof, it can back up under shingles and find its way into your house, causing damage.
Getting snow off the roof (hard and dangerous work) helps, as does getting rid of the ice dam with heat cables or by hiring a contractor to melt it away. The more permanent solution is to make sure your attic has proper insulation and ventilation. This stops the escape of heat which is really the root of the problem.
