Common Attic Insulation Problems

Proper attic insulation is very important during our cold Minnesota winters. Hear from our COO, Andy Lindus as he addresses common issues we’ve seen with attic insulation.

Spray Foam Insulation Problems

While properly installed insulation can be a game-changer in a home, so too can poorly installed insulation. Earlier this week, a homeowner reached out to us because they were noticing water infiltration in their home and thought their metal roof might be leaking.  When our team went out to their property to investigate, they were stunned by what they saw.

The spray foam insulation in the attic was applied directly to the roof deck because it was a non-vented area.  The problem arose because the application of the spray foam was uneven.  In some areas it was as thick as three inches and other areas it was less than an inch.  There were spots where the spray foam was cracking and falling off the roof deck.

The most likely reason this happened?  An inexperienced or negligent contractor installed the spray foam insulation at too cold of a temperature.  While it can be an inconvenience to have a home improvement project pushed off due to weather conditions, the long-term failure to install products in compliance with the manufacturer’s specifications can have catastrophic effects.

A text message came from a homeowner that was noticing frost on their roof deck and they were curious to learn if all of the preexisting insulation needed be removed or if it could be salvaged since it had not yet gotten wet.

Andy assured them it was unlikely the current insulation needed to be replaced.  However, the situation wouldn’t be remedied simply by adding new insulation because the root of the problem was an air infiltration issue.  Remedying the situation requires the utilization of attic air sealing.

The reason frost is materializing is because warm air is escaping from the home and coming in contact with the cold roof deck, and forming condensation.  When this happens, frost forms.  Once temperatures increase, the frost thaws, causing moisture in the attic.

Our Recent Insulation Reviews:

"Lindus Construction did a great job of removing old insulation in our attic and then sprayed foam insulation to seal the air leaks in both our attic and basement. They then installed new insulation to meet current building codes and corrected venting issues. Randall kept me updated me updated at each step of project which I appreciated. The Lindus team was very courteous and did great job of keeping our house clean during this time."

"Randall Bowman and an attic insulation crew attended to my Somerset, WI condo in Oct. 2023.  They were ahead of schedule, very conscientious about not causing any damage or mess in the house. Very conscientious about not blocking traffic for my condo development neighbors. And, they were very efficient-- finishing earlier than they estimated. I would highly recommend Lindus Construction and the two insulation company they contract with."

"Mitch did an outstanding job at my home today. He made me feel extremely comfortable. He was extremely thorough. And explained everything down to the down to the bottom detail. I couldn't be more happier. And if I know anybody that needs any work done, I am certainly going to recommend Lindus Construction. So thank you very much."
