Ice dam removers in for a chaotic season

Posted: Updated:

Ice dam removers are in for a chaotic season with the mix of snow, subzero temperatures and thawing that haven't exactly come in succession this year.

Minnesota roofs could be in trouble this year with the tumultuous weather, and the Minnesota Department of Commerce says homeowners may want to hire a professional ice dam removal company.

REMOVAL AND PREVENTION TIPS

-Removing ice from the roof with shovels, chippers, axes, chemicals or heat can damage shingles, gutters and other building components.

-Ice dam removal companies use steamers, which could be the homeowner's best option.

-Attack the root cause of ice dams - attic air leaks. Sealing air leaks will help prevent ice dams and save on energy bills.

-Seal attic air leaks around wires, plumbing vents, light fixtures and chimneys with caulking or expanding spray foam, and attic insulation should be installed to a minimum R-50 as space allows.

WHY DO ICE DAMS FORM?

Ice dams occur when heat leaks into the attic and melts the underside of the snow on the roof, the Departments of Commerce says. Next, melted snow flows down the roof where it freezes, then more ice and snowmelt can pile up.

The ice buildup can back up under shingles, damaging them and allowing water to leak to the ceilings and walls below.
