National blogs own “ice dam water damage” because local restoration companies never wrote the Upstate version. Lake-effect snow, attic heat, and cold eaves are how water gets into Pittsford colonials, Irondequoit capes, and Greece ranches every winter. This is that page — for homeowners in Rochester and the towns around it.
Key Takeaways
- An ice dam is a freeze-thaw dam at the eave. Meltwater backs under shingles into insulation and ceiling drywall.
- Interior drying is restoration. Replacing shingles is roofing. You usually need both, in that order if water is already inside.
- Do not wait for April if you already have stains, dripping, or wet insulation.
- See also our storm damage restoration and water damage pages.
How Ice Dams Form Here
Heat leaks into the attic, snow on the upper roof melts, water runs to a colder eave, and refreezes. The dam grows. The next melt has nowhere to go except under the shingles. Lake Ontario and Finger Lakes winters load roofs with snow that sits for weeks. Poor soffit ventilation and thick insulation gaps make it worse on older two-story homes in Penfield, Webster, and the city.
Where the Water Actually Goes
Not always the room under the leak. Water follows sheathing, wiring holes, and party walls. We find wet insulation, stained plaster, and mold in attics months after the ice is gone. If growth exceeds 10 square feet, New York Article 32 applies — independent assessor, then remediator.
First Hours After You See a Stain
- Catch dripping with buckets. Keep people off wet plaster ceilings.
- Photograph every room, including the attic hatch.
- If you can reach the panel dry, kill power to saturated fixtures.
- Call restoration for interior extraction and drying. Call a roofer for the dam and shingles — or we coordinate both.
- Do not run space heaters at the eave from a ladder on ice.
Tarping vs Interior Drying
Emergency tarping or shrink wrap stops new water. It does not dry the cavity that already flooded. Leaving wet insulation in place is how spring attic mold starts. Our storm crews tarp when the roof is open; water crews meter the interior. Towns we run constantly: Rochester, Greece, Webster, Henrietta, Irondequoit, Brighton, Pittsford, Penfield.
Storm-Chaser Warning
After a lake-effect event, out-of-state trucks show up with lowball roofing prices and no local license trail. Restoration for insurance should be a company you can still call in July. We are Rock Emergency Services Inc., 69 Seneca Ave, (585) 501-3606 — rockemergency.com, not rockenv.com.
FAQ
Does homeowners insurance cover ice dam leaks?
Often yes when water enters through the roof from ice and snow, depending on the policy and maintenance. The adjuster still wants moisture documentation. We provide it.
Can I salt the roof myself?
Calcium chloride sock methods exist. Working from a frozen roof is how people get hurt. If water is already inside, dry the house first.
Call 585-501-3606 when the ceiling is wet. Waiting for a thaw is how a stain becomes an attic mold job.
