Spray Foam Insulation in Breezy Point, MN

Spray Foam Insulation in Breezy Point gets a lot of questions about ice. Rows of icicles and a thick ridge at the eaves are common sights on Pelican Lake roofs after a big snow, and they almost always come from heat leaking out of the house below. Minnesota Rule 1303.1700 sets the ground snow load for Crow Wing County at 60 pounds per square foot, among the heaviest in the state, so roofs here carry a deep blanket for months.

How the ice forms

Warm air from the house slips into the attic through gaps around lights, bath fans, plumbing vents and the attic hatch. That warms the roof deck, the snow on top melts, and the water runs down until it hits the cold overhang, where it freezes. Each melt adds to the ridge, and water can back up under the shingles.

Air sealing does most of the work

Adding more insulation without sealing those gaps helps less than people expect. We seal the bypasses first, often with spray foam around the penetrations and the top plates, and then bring the attic floor up to depth. For an attic here with no insulation, DOE's target is R-60.

Complicated rooflines

Vacation homes and rebuilt resort properties often have vaulted ceilings, dormers and multiple roof valleys. Where a ceiling follows the roof and there is no attic to work in, closed-cell foam sprayed against the roof deck from below can insulate and seal the space without needing a vent channel. We look at each section of the roof separately, since one house can need two or three methods.

A part-time house and ice

Breezy Point had 1,738 housing units in 2020, and 41.0% were vacant on census day. A house set low while the owners are away melts less snow, but heat loss still shows up the first weekend everyone arrives and turns the thermostat up. Sealing the attic reduces that start-and-stop melting too.
