A Brief Overview of 4 Causes of Attic Mold



Although we may not always think of it, mold is a common problem for homeowners. It can be easy to overlook mold simply because it occurs in areas that we don’t visit often; the attic is a perfect example. However, considering that it’s a part of your own home, you still want the attic to be well-kept. It’s wise to take proper preventative measures, as they save us from a headache in the future. But what causes mold in the first place? Knowing the answer to that question may help you avoid a potential future problem.


1. Leaks

Given its proximity to your roof, your attic is particularly susceptible to leaks. As it doesn’t take much moisture to grow a substantial amount of mold, a small leak can quickly cause a big problem. It also doesn’t take long for mold to grow—only 24 to 48 hours. If you’ve recently experienced a rainstorm, be sure to check your attic to confirm that everything is completely dry.


2. Insulation 

Poor insulation can play a huge role in mold production. Having a proper airflow is integral to preventing it. If your duct systems aren’t properly installed, you risk losing up to 60% of heated air before it can reach the register. If the warm air from your home comes in contact with the cold air in your attic, condensation can occur, which would cause mold to grow.


3. Ventilation

Another common problem is inadequate ventilation. It’s important to be sure that you are not covering your vents with insulation. The air that travels up to your attic from exhaust vents around your house can become trapped in your attic and rob it of its ability to ventilate. If your attic does not have proper air flow, it increases the chances of mold growth.


4. Feeding the Mold

Black mold is sure to thrive so long as it has something to consume—and if not cared for, your attic act as a mold buffet. Black mold lives off an organic compound called cellulose, which is present in many types of wood. When that wood gets wet, mold is sure to make a feast out of it.


Overview

All these origins point to one thing—moisture. At the end of the day, so long as there is precipitation, mold has the means to survive. What you need to be aware of are the different ways your attic can receive unwanted moisture and practice regular maintenance.
