Winter Home Maintenance Checklist
Winter home maintenance is about monitoring, protecting vulnerable systems, and responding quickly to weather events. Most of the big winterizing work should have been done in fall — what remains is watching for ice dams, keeping heating systems running efficiently, and knowing what to do when temperatures drop dangerously low. This 10-task checklist focuses on the most impactful winter tasks that prevent the most common and expensive cold-weather emergencies.

At what temperature do pipes freeze?
Pipes in uninsulated or poorly insulated areas begin to freeze at 20°F (-6°C). Pipes in interior walls rarely freeze unless there is a prolonged power outage. When temperatures drop below 20°F, let faucets on exterior walls drip slightly and open cabinet doors under sinks.
How do I prevent ice dams on my roof?
Ice dams are caused by heat escaping through the roof melting snow. Long-term solutions include improving attic insulation and ensuring adequate attic ventilation. Short-term: use a roof rake to clear snow from the lower 3 feet of your roof after each snowfall. Never chip ice off the roof — this damages shingles.
What should I do if my pipes freeze?
Shut off the main water supply immediately to limit flooding if the pipe has cracked. Apply gentle heat to the frozen section using a hair dryer — never open flame. Start from the faucet end and work toward the frozen section. If you cannot locate the freeze, call a plumber.
How cold is too cold for a house?
Set your thermostat no lower than 55°F when the house is unoccupied. Below 55°F, pipes in exterior walls and unheated spaces risk freezing. If you're leaving for an extended period, have someone check the house daily, or use a smart thermostat that alerts you if temperatures drop unexpectedly.
