Often times when mold is in your home, you might not even know it. It can be behind the drywall, under your carpet, or in the case of this blog, in your attic. People don't go in their attic much, so this mold can be left unnoticed for months, even years.
There are a couple reasons that mold may begin to grow in your attic, with them being ventilation issues, improper bathroom fan exhaust, or roof issues.
Ventilation issues may stem from blocked soffits or vents. It is common for them to be blocked by insulation. Having too few vents in your attic can also lead to mold growth.
Bathroom fan exhausts are meant to pump moisture out of your home and into the outside air. It is important to check this and make sure the moisture is properly being sent outside and not in the attic.
Roof issues, such as leaks, can be a major factor in having mold in your attic. Often times the mold will tend to grow near where the leak is occurring. If you notice mold in a centralized spot, there is a good chance that is where the leak is occurring.
