Ice dams and ventilation
Steam removal for ice dams in winter, then the attic ventilation work that stops them coming back.
Typical price
From $425
Time on site
Same week
Steaming
We remove ice dams with low-pressure steam. No hammers, no chisels and no salt pucks on the roof, all of which damage shingles. Steaming costs $425 for the first hour and $275 for each hour after. A typical bungalow eave takes two to three hours.
Why they keep coming back
An ice dam forms when warm air from the house melts snow on the upper roof and the water refreezes at the cold eave. Heat cables treat the symptom. Sealing air leaks into the attic and balancing intake and exhaust ventilation stops it.
Ventilation work runs $1,600 to $4,800: soffit intake vents, baffles above the insulation, and a ridge vent. For air sealing and insulation we work with a Minneapolis insulation contractor and coordinate the schedule.
