Why mold grows in attics

So first of all, mold in attics is more common in colder parts of the country.

Mold usually starts to develop when warm, moist air is vented or leaks from your living space into the attic space.

This can happen from shower fans or stove hoods that don’t vent to the outside like they should… Or simply from warm air leaking through light and other ceiling fixtures.

When this moist air hits the underside of cold roof sheathing, it condenses, then drips down the rafters and can saturate the attic insulation.

Voila! It’s the perfect environment for mold to grow.

The chief reason this happens?

Poor, inadequate attic ventilation!

You see, air needs to circulate properly through the attic and under your roof, flowing out the ridge or gable…

If warm, moist air gets trapped in the attic with nowhere to go, mold can grow.

Wood starts rotting, and people start getting sick. Not a fun time, and it’s kind of gross, too.

You can avoid this from happening to you.

You just need to make sure your roof and attic are properly and adequately ventilated with the right combination of soffit, ridge, and gable vents.

We’ve even seen roofs right here in Maryland where the original roofer never even cut in the ridge vent at all, trapping all the moisture right where you don’t want it – inside your attic.

If your roof is properly, you probably won’t have to worry about mold.
