Ice Dams at the Gutter

- What It Means
- Meltwater pools behind the ice. Eave laps get sealed so that water has nowhere to go.

Service Area · Thomaston, CT
As a Thomaston metal roof coating contractor, we seal and coat factory roofs that leak at the eaves when ice holds back meltwater.

Thomaston metal roof coating calls often start the same way: water at the top of a wall on a mild day after snow. Snow melts during the day, refreezes at the colder eave, and the ice holds meltwater that backs up under end laps and trim.
We seal the eave laps, trim, and gutter joints and carry the coating over them, so water held by ice has no open joint to enter.
On Thomaston factory roofs, the eave is where winter damage concentrates.
Coating the eave line on a Thomaston factory brings these four gains.
Sealed laps and trim leave meltwater no open joint to back into.
Cleared, sealed gutters move melt away instead of feeding ice.
Primed and coated panel ends stop rusting where water sits longest.
Fewer winter leaks onto machines and stock below the walls.
Thomaston factory roofs mostly take the metal system, with others where the roof calls for it.

The standard choice for Thomaston factory roofs, with eave laps and trim sealed first.

The eave gets extra steps before the field coat goes on.
We walk the eave line, open a few end laps, check trim and gutter joints, and look for stains on interior walls below.
Gutters and downspouts are cleared, and loose or leaking joints are refastened and sealed.
End laps and trim get sealant and fabric set in coating along the full eave.
The field coat runs down over the eave laps and trim to full thickness.

Daytime melt refreezes at the colder eave and gutter, and the ice holds back water that then runs under end laps and trim. Sealing those laps and joints and coating over them closes the path.
Eave sealing and gutter repair add prep, which moves a roof within the published $2.50 to $4.00 per square foot range. The estimate lists eave work as its own line.
Coating is, since it needs warm, dry weather to cure. Gutter clearing and temporary eave sealing can happen in winter when the leaks show up.
They can reduce ice, but they add rooftop penetrations and wiring to detail. We work around existing cables and flash any mounts before coating.
Sealed joints keep held water out, and coating is what seals them. Ice still forms when snow melts and refreezes, so clear gutters remain part of the fix.
Thomaston's building department makes that call from the scope. Sealing eave laps and coating is lighter work than cutting out rusted eave panels or repairing the framing behind them, so any panel or structural items get their own lines in the estimate.
Yes. Eave sealing and coating happen from the roof and from lifts outside the building. Areas below active work at the walls are marked so staff and stock stay clear while the crew works overhead.
Tell us where the walls get wet after snow. We will check the eave line and price the coating.
