Ice Dam Removal & Prevention in Grand Island, NY

Grand Island is north of Buffalo; NWS Buffalo says areas south of the city get much more lake-effect snow than areas to the north.NWS Buffalo’s 2025–2026 winter summary notes that the January 19–21, 2026 lake-effect event left about a foot of snow across Grand Island and Niagara County.

NWS Buffalo's November 2014 and November 2022 storm reports list no observation point in Grand Island itself.

Ice dams form when heat leaking into the attic melts roof snow that refreezes at the cold eaves. The University of Minnesota Extension says air leaking from the house is the major source of that heat in many homes, and advises air-sealing the ceiling first, then adding insulation.

Erie County's list says the Town of Grand Island requires plumbers and electricians to be licensed; it lists no roofing or general home improvement license. Permits can still apply, so check with the building department before work starts.

Everywhere in New York, General Business Law requires a written contract for most home improvement jobs over $500 with a three-day right to cancel. Roofers must show workers' compensation and liability insurance, cannot require a deposit, and cannot offer to cover your deductible. See our roofer licensing guide.
