Steam Roof Snow and Ice Dam Removal Minneapolis MN
Ice Dams Have Been A Big Problem For Minnesota Homeowners
Ice Dam Defense
Ice damming has been a big problem here in Minnesota this year. Record snowfall amounts in December, preceded and interspersed by bouts of sleety precipitation, produced the perfect storm for ice dams to flourish.
Although sometimes thought of as a problem with roofing or attic ventilation, ice dams are actually caused by the presence of warm air in the attic, combined with snow on the roof and the right weather conditions. Ice dams occur when heat leaks into the attic and melts the underside of the snow on the roof. The melted snow then flows down the roof surface until it reaches a cold spot (such as the eaves or soffit) where it forms a frozen dam, behind which more snowmelt and ice pile up.
The ice build-up can back up under the shingles, damaging them and allowing water to leak to the ceilings and walls below.
The source of ice dams: attic air leaks
Warm air leaking from the house into the attic is the primary cause of ice dams. Anywhere there is a penetration into the attic space (around wires, plumbing vents, light fixtures, chimneys, and knee walls) there is the potential for air leaks. Even homes that are only a few years old may not be properly sealed. To avoid these types of problems and eliminate most ice dams, attic air leaks must be sealed with caulking or expanding spray foam.
- Sealing attic air leaks saves energy and is key to preventing ice dams.
- An energy audit with an infrared scan can pinpoint trouble spots.
- If damage has occurred and ice must be removed, hiring professionals that use steamers is strongly recommended.
Ice Dam Defense
There are 3 ways to defend against the damage ice dams cause. All 3 work together.
- Insulation/ Insulation keeps heat from escaping from your home’s living space into your attic.
- Ventilation/ Ventilation removes the heat and keeps the roof deck evenly cool to help prevent snow from melting on the roof.
- Water-proofing/Water-proofing is laid across the roof before shingles are applied and protects against dams that form on the roof.
With existing roofs, waterproofing underlayment is only an option if you remove the existing shingles or are building a new addition. Either way, increasing the insulation R-value in the attic is always possible, and ventilation can usually be added to your attic quite easily.
