ICE AND SNOW CAN DAMAGE YOUR ROOF, YOUR GUTTERS, YOUR INTERIOR, AND CAN INCREASE THE HAZARD OF SLIPPING AND FALLING.
When snow falls on your roof, some of it melts and runs down to the roof overhang. Since the overhang has no insulation beneath it, the water begins to drip and suddenly refreezes, forming icicles.
Icicles pose obvious safety risks to people, either by falling on them directly or by dripping onto driveways and walkways. This can create dangerous ice patches on the ground. Because water expands as it freezes, it can ruin your gutters and even work its way into the internal structures of your home causing expensive internal water damage.
