Why Am I Seeing Condensation in My Attic?

mold from high humidity and moisture in attic space
October 28, 2020

Maybe you don’t go up into your unfinished attic very often—just every couple of months to take things out of storage or put them away for the season. So you might not be completely in tune with what’s going on up there, and it can be a little bit of a surprise if you open the attic hatch or door to find something you weren’t expecting.

If you’ve recently gone up into the attic of your Milwaukee area home and you’ve noticed condensation on the attic rafters, or it smelled wet or damp, it’s perfectly understandable that you might be alarmed. Do you have a leak in your roof? Is this an emergency? Here’s what you need to know about frost or moisture issues in an attic and what the best solutions are to fix them.

Is Moisture in My Attic a Problem?

This one is easy to answer: yes! Anytime you have water or moisture inside your home is cause for concern, for a few different reasons. First, high humidity, moisture, or water can cause structural damage to the building materials that make up your home. Wood rot on your attic rafters or attic floor isn’t something that will go away if the moisture problem isn’t addressed, and odds are that if left alone for long enough, you’ll even start to see signs of water damage in the living spaces of your home, like the ceilings of your second floor.

Moisture and water can also reduce the effectiveness of your attic insulation, leaving you more exposed to outdoor weather and more likely to suffer from high heating and cooling bills. If your house feels humid all the time due to moisture infiltration, you’re also at risk for mold growth, including black mold, which is a real indoor health hazard!

Why is Water in My Attic and How Do I Get Rid of It?

Condensation and frost in your attic is primarily the result of poor attic insulation and air leaks between the top floors of your home and your attic space. If warm air from your home’s living spaces rises and is able to pass through underinsulated areas or escape through cracks and air leaks, it will get into your attic space, and when that warm air meets the cooler temperatures in your attic, particularly on your attic rafters, condensation and frost occurs.

The key to getting rid of attic condensation is to upgrade your insulation and air sealing to prevent the warm air and heat in your home from escaping! Not only will you avoid water and frost in your attic, but you’ll stay more comfortable in your home and improve your energy efficiency, which means you’ll spend less on heating costs as well!
