4 Signs of an Attic Insulation Problem


Estimated reading time: 3 minutes

We often remove and replace attic insulation. But how do you even know you have an insulation problem?

There are four key indicators that we look for, and you can look for them too. 


This is probably the problem most people find. Everyone’s got that one hot or cold room in their house! Or maybe it’s the whole upstairs. Sometimes it’s the office; sometimes, it’s even the main bedroom. Sometimes cold (or hot) rooms are correlated with the distance the room is from the AC/heating system or whether it’s an add-on to the original house.

But most of the time, a hot or cold room is caused by inconsistent attic insulation. You may have 10 inches in one place but only six or four in another! Consistency is even more important than depth, in our opinion. So if you have a cold room in your house, more than likely, it’s an insulation problem, not just an architectural or design problem.

Cycling thermostat

If your thermostat is going crazy, cycling on and off; if it feels stuffy sometimes and then really cold at others, your thermostat is getting confused! One of the problems in a house with excellent insulation is that you might have to keep turning the thermostat up higher and higher because it will get to the temperature I’ve set it to and stay off.

Then the house will start to feel colder, just because the heat hasn’t run in a long time because the sound insulation keeps the system off! But if you keep having to lower your thermostat because your heater is trying to run all the time—you might have an insulation problem. So if your thermostat is cycling on and off, or you can’t get it to turn off, that’s a vital indicator of an insulation issue.


This is typically more of a window or door issue. Suppose part of your house feels drafty or cool in some areas. In that case, that can be a crucial indicator of an insulation inconsistency, or maybe insulation is missing altogether from a specific part of the house. 

Can lights

Remember the recessed lighting in homes in the 70s, 80s, and 90s? If you have more than ten can lights in an average 2,000 or 3,000 square-foot home, they could be causing you trouble. The problem is that there is typically no insulation over those can lights, leaving you with areas of inconsistent insulation where heat or air can escape. So if you have a lot of can lights, that’s an area you want to check to see if you have an insulation problem. 

We are more than happy to come out and look at your house to see if your insulation is reasonable and consistent! But you can start with these tips and see how things look.
