Insulation Contractors in Roseville, MN
Roseville sits between the two downtowns and was largely built in the post-war decades, which means a lot of attics holding material nobody has measured since.
Post-War Housing and What It Left Behind
A great deal of Roseville went up in the decades after the war, when the attic spec was whatever met the code of the day and air sealing was not part of the conversation at all. Those attics usually still hold their original material, settled well below the depth it started at, over a ceiling plane full of unsealed penetrations. Both halves of that need addressing, and only one of them is about adding insulation.
Ice Dams Are the Local Symptom
Warm air escaping through the ceiling warms the roof deck, snow melts, the water runs to the cold eave and refreezes. The dam that forms backs water under the shingles. It presents as a roofing problem and gets treated as one, but the cause is heat and air reaching the deck, which is why the lasting fix is at the ceiling plane rather than on the roof.
Rim Joists and the Basement Band
Minnesota houses nearly all sit on full basements, and the band where the floor structure meets the foundation is one of the largest and least examined air leaks in the building. Sealing and insulating the rim joist is a small, contained piece of work with a result people notice, and it is usually quoted alongside attic work rather than instead of it.
Questions
Common questions
Do you cover Roseville?
Yes, Roseville and the surrounding Ramsey County communities are inside the regular service area.
Will insulation stop my ice dams?
Insulation plus air sealing will, because together they keep the roof deck cold. Depth on its own does not, since it does not stop air movement.
My house is from the 1950s. Is the attic worth doing?
Usually, and often it is the highest-return work available on a house of that age, because the starting point is so far back.
