When was the last time you went to your attic? If you are like most
folks, you probably only go up there once or twice a year to store
holiday decorations. It may never even occur to you that your attic
could be a breeding ground for mold.
If you think mold only happens in bathrooms and basements, think
again. They thrive in damp, dusty areas, making attics the perfect
place for all kinds of mold. To help protect the health of your family
and your home, here are some of the main causes of attic mold.
1. Leaking roof
One of the major sources of mold growing in your attic is a leaking
roof. Clogged gutters, damaged flashing, or missing shingles can
cause roof leaks, leading to moisture accumulation in the attic. Even
the tiniest leak can lead to a mold problem, so it is important to inspect
your attic several times a year. Make sure to check roof valleys,
skylights, chimneys, and pipes for signs of moisture buildup.
2. Improper attic insulation
Saving money on heating and cooling bills is a top priority for most
homeowners. But improperly installing or choosing the wrong kind of
installation can lead to moisture problems and attic mold. If you are
not sure how to properly install insulation yourself, get some help from
a professional. It may cost more than doing it yourself, but it could
save you a serious mold problem and more expenses down the road.
3. Inadequate insulation around fixtures
Ceiling fixtures that are not properly sealed could also be the cause of
attic mold. Warm air that escapes through openings around the
fixtures rises and meets the cold attic walls above, resulting in
condensation. Over time, mold can form and spread throughout your
4. Inadequate attic ventilation
Another main reason for attic mold is poor ventilation. Blocked or
sealed-off attic vents will keep moist, warm air trapped inside, creating
the perfect conditions for mold growth. Check your attic vents to make
sure they are free from insulation or debris that could obstruct them
from sufficient air flow.
5. Fans vented into the attic
If there are dryer vents, plumbing vents, or kitchen or bathroom fans
that are vented into the attic, you could have a mold problem. These
are all major sources of condensation, leading to mold growth. If
you’ve noticed that your vents are routed into to attic, hire a contractor
to re-route those vents outside.
Think you have a mold in your attic? Then you’ll need to do something
about it as soon as possible. Mold grows fast and can spread quickly,
putting your home and your family’s health at risk.
Getting rid of mold can be a complicated process, so it is always a
good idea to contact an experienced mold remediation professional.
They have the tools and the knowledge to not only inspect, test, and
remove mold, but also eliminate the source of it to ensure it won’t
