Spray foam insulation applied along a gable roof attic in Chelsea, MI improving energy efficiency and indoor comfort.

Homeowner in Chelsea reached out because the upstairs just didn’t feel the same as the rest of the house. Not extreme or anything, just… off. By the time you got into the afternoon, you could feel it. Warmer than it should be, even with the system running. They had already played around with the thermostat a few times thinking maybe that was it. It wasn’t.

What We Found

Once we got up into the attic, it kind of clicked pretty quick. Nothing looked completely wrong at first, which is usually how these go. But the insulation wasn’t even across the space, and in a few areas you could actually feel air moving through if you stopped for a second. Some of it had settled down over time, some spots just weren’t doing much anymore. Nothing major on its own, but all together it explained why things never felt consistent upstairs. We run into this a lot around Chelsea.

Why This Happens

A lot of people think the answer is just adding more insulation on top of what’s already there. Sometimes that helps a bit. But if air is still moving through that space, it doesn’t really fix the issue. You’re just adding more material into a space that isn’t controlled. That’s usually the part that gets missed. The Building America Solution Center has a good breakdown of how air movement affects insulation performance, and honestly it lines up with what we see in homes like this all the time.

What We Did

For this one, we went with spray foam along the roofline instead of building up the attic floor again. With the gable roof setup, it just made more sense to bring that whole space inside the envelope instead of trying to fight it from below. Once the foam goes in, it seals things up and stops that constant airflow. At that point it’s not just insulation — you’re actually controlling the space.

How It Went

From our side, everything went smooth. We got in, worked through it, and didn’t drag the job out longer than it needed to be. Cleaned everything up before we left too. That part always matters, even if people don’t think about it at first.

Homeowner said it better than we could:
“Upstairs used to heat up every afternoon no matter what we did. Now it just stays comfortable. We don’t even think about it anymore.”

Results

It wasn’t one of those instant, dramatic changes right away. More like things just leveled out. The upstairs didn’t heat up the same way, the system didn’t seem like it was running as hard, and the whole house felt a lot more even. That’s usually when you can tell things are finally working the way they should.

Local Context

We see this type of setup all the time in Chelsea and around the greater Ann Arbor area. It’s usually not that insulation is completely missing or anything like that. It’s just not working the way it should anymore. And over time, that starts to show up in comfort first before anything else.
