The harshness of the winter of 2019 will long remain in the memories of Minneapolis homeowners. Cold temperatures and ice were prevalent, and February set a snowfall record. These conditions provided the optimum opportunity for ice dam damage.
An ice dam is a sheet of ice that forms on the edge of a roof that prevents melting snow from being able to exit the roof. Instead, the sheet of ice causes water to back-up underneath the roof’s shingles, into the soffits, and eventually into the interior of a home.
Story and a half homes, like the one our client, Jack owns, are particularly susceptible to ice dam damage because they lack a conventional attic, making them tricky to insulate and ventilate. Jack had attempted the use of heat tape on his roof to alleviate ice dams, but to not avail. The zippering of his home’s shingles was further evidence that a new roof was also needed.
Here was the long-term solution our team proposed in order to ward off future ice dam quandaries.
Insulation: In order to curtail future ice dam damage, our team needed to create a hot roof through the use of five inches of spray foam insulation. The entire roof cavity is filled as the material expands. The installation of a hot roof eliminated the need for ventilation because the spray foam insulation is affixed on top of the roof sheathing. This approach raised the R-value of Jack’s home because it prevented future air leakage and heat loss, which are a root causes of ice dams.
Roofing: Wanting to avoid future ice dam damage, Jack leaned on us for advice on the roofing material that should be used on his home. Our suggestion was that he make the switch away from asphalt roof shingles to residential metal roofing. The surface of a metal roof is slippery, and it provides a straightforward method for ice and snow to quickly exit the roof. The lifespan of a metal roof also made it an optimum choice for Jack who was looking to make this roof the last he’d ever install on his home. Made of highly recycled content, Jack’s metal roof is guaranteed to never rot, crack, warp, of flake. From an aesthetics standpoint, the metal roof also improved Jack’s curb appeal, while also providing an opportunity for insurance savings due to the material’s resistance to hail and fire.
Upon conclusion of his project, Jack had this to say, “The job went well and the installers were wonderful people. I like the looks of my home including color and how everything was done. It looks so much better and I know it’s going to be way better in the wintertime for me, so I’m looking forward to that.”
