1. Leak in your Roof
One of the most common ways mold will grow is a leak from
the roof. When rain or snow hits your roof, the moister will pour into any open
cracks or leaks directly into the attic. When it is snowing, look for any bare patches
on your roof. This could indicate that heat is leaving the attic out through
the roof, causing the snow to melt and drip inside. The attic isn’t regularly
visited, take precaution next time you go up there. If you encounter any mold,
get your roof inspected and repaired.
2. Attic Insulation
Many DIY homeowners feel a good way to save money on bills
is to insulate the attic themselves. If the wrong type of insulation is used or
installed incorrectly, it can actually hold in the moisture received from a
leaky roof or any moisture from the lower floors. If the insulation stays damp,
mold will continue to develop. Be sure to do your homework if you feel like
doing your own insulation up in the attic or call a technician to properly
asses how to approach your next project.
3. Poor Airflow
Homeowners tend to shut off all vents that lead to the
attic. Doing this, they think shutting them off means nothing will get in.
Which sadly means there will be a poor circulation of air flow. Having that
constant ventilation allows any type of dampness to expel faster than it would
being shut off from outside airflow.
4. Vents in the Home
Make sure that you don’t have any vents (kitchen, bathroom
fans, dryer) leading directly into the attic. If you do, contact a handyman to
re-route those vents to go outside. Pumping in this heat constantly will
contribute to the poor airflow in the attic and accelerate mold growth.
