Homes near trees may need quarterly cleanings to prevent clogs that cause water damage and ice dams. Regular gutter maintenance protects your roof, siding, and foundation from water infiltration.

Ice dams form when heat from your attic melts snow on the roof, which refreezes at the colder eaves. This creates a barrier that traps water, leading to leaks and damage. Proper attic insulation, ventilation, and timely snow removal prevent ice dam formation during New Hampshire winters.
