Home Inspection: Mold Found in Attic – Deal Breaker?


Mold is one of the big fear items that home buyers in Victoria, Cowichan, Duncan, Nanaimo, Parksville, Qualicum, Courtenay, Comox, Campbell River, and Port Alberni ask about during the home inspection process. Simply put if you see mold in a home there is a moisture issue.

Once the source of the moisture is addressed and the mold is remediated by a qualified professional it won’t come back. It’s that simple. Mold needs moisture to grow.

Is mold in my home a problem?

It can be if left undressed. Again, mold in a building means you have a water problem. Dry buildings do not have mold problems. Focus on solving the water problem, then decontaminating the mold. If you do not solve the water problem you will be in an endless cycle of never ending mold.

Is mold harmful to my health?

The short answer is No. The long answer is it can be with prolonged exposure. However, we have very little science to prove that mold exposure in buildings can affect human health and a great deal of evidence to suggest it can’t.

Mold in attic spaces.

If we look at mold in our attic spaces it is not likely an indoor air quality issue. Air rises through the lower levels of the home and up through the attic. Mold spores do not travel against this air flow so most of this air will make it’s way out of an upper roof cavity or vent.

If you were to find mold in your crawlspace it is much more likely that that air is going to contribute to the interior air we breathe in. Simply put, we breath the air that is below our home.

Why does mold grow in my attic space?

Think about when you take a shower. The warmer air from inside the shower will meet the cooler air from in the room and you will end up with condensation on your bathroom mirror. The same is true for your attic space. During the winter months your roof is very cold. If the warmer interior air from your home migrates into your attic space you will end up with condensation on your roof sheathing, which will lead to mold.

Why is Mold in my attic a problem?

Although mold in your attic does not lead to indoor air quality issues, it can lead to deterioration of your roof structure. Once again, if the moisture issue is not addresses the mold will continue to grow and spread and will come up each time the home is inspected in the future.

There are three areas that lead to condensation in attic spaces:

Not enough ventilation that will allow the outside air to keep the attic air the same temperature.

Not enough insulation to keep the warmer air from the home from moving into the attic space.

All ceiling penetration sealed to prevent further heat loss into the attic space.
