Ice Dam Prevention: Your 60-Minute Block Plan
Ice dams are simple physics. Warm air leaks into the attic, melts rooftop snow, meltwater hits a cold eave, refreezes, and backs up under shingles. The result? Water damage. Yikes! The fix is not a panic-salt; it is stopping the warm leak, moving air right, and clearing snow the smart way. Here’s the plan I’m running on my street.
1) Seal the attic hatch (10 minutes)
Weatherstrip the hatch perimeter and glue a piece of rigid foam to the back. Your warm air stays in the house where it belongs.
How-to → Attic Hatch Guide
2) Make bath fans do their actual job (10 minutes)
Moist air feeds attic frost. Swap the switch for a countdown timer and set 20 minutes after showers.
Book it → Green Home Services
3) Roof-rake loop after big snows (15 minutes)
Clear the first 3–4 feet above the eaves. Work from the ground, short pulls, no heroics. Team up with two neighbors and rotate houses.

4) Heat-cable sanity check (10 minutes)
If you already have cables, make sure the outlet is GFCI-protected, the cover is extra-duty and closes over the plug, and the cable is intact and routed per the manufacturer.

Quick FAQ
Do heat cables replace insulation or air sealing
No. Cables are for problem eaves. The big win is stopping warm air leaks.
What if my bath fan is loud
Clean the grille first. If it still screams, plan a replacement in spring and use the timer in the meantime.
How do we keep it affordable
Bundle houses. One route = fewer miles = better pricing.
