How to Prevent Attic Mold

While mold can grow in just about every condition, it prefers summer the most out of all the seasons. If you haven’t already taken steps to prevent attic mold in your home, it’s not too late. Catching and remediating mold before it has spread to the entire home will save you a lot of time, hassle, and cost.

Causes of Attic Mold

First, let’s take a look at the causes of attic mold. As you may know, mold can live in almost any condition. However, it thrives in certain conditions – all of which are in abundant supply during Atlanta summers.

Causes of attic mold include:

  • Heat: Mold grows more readily in warm conditions, especially within the 60 – 80 degrees range. Attics not only get warm quickly during the summer months, they hold onto heat long after the sun has set.
  • Moisture: Mold thrives in damp conditions. Attics hold onto a surprising amount of moisture. This is especially true in a humid area like Atlanta. The natural humidity combined with attics holding onto moisture provides mold with optimal growing conditions.
  • Roof leaks: Similar to ‘moisture’, roof leaks can go undetected for weeks or months without being noticed simply because of how infrequently homeowners visit their attic. The additional moisture from a leaking roof can quickly accelerate mold growth and cause structural damage.
  • Lack of ventilation: Unless an attic has been converted into a living space with regular airflow, there’s a good chance that an unfinished attic is not well-ventilated. Poor ventilation combines with heat and humidity to create the perfect incubator for mold spores.
  • Food supply: Mold needs a supply of food to survive, such as wood and fiber. Both of these are readily available in any attic space.


As you can see, attics are an ideal environment for mold spores to grow and thrive. But no homeowner wants uninvited guests, especially since mold can be damaging to the structure as well as the health of the home’s occupants.

How to Prevent Attic Mold

The best way to prevent attic mold is to ensure that the conditions within your attic are not suitable for growing.

  • Check Bathroom, Laundry, and Kitchen Exhausts: Sometimes, past shoddy or lazy workmanship finds exhaust pipes from high-humidity areas like the bathroom, laundry, or kitchen venting directly into the attic. Identifying and solving these problem spots can help prevent unnecessary humidity buildup in the attic.
  • Install Ventilation: Installing ventilation in the attic is a great way to keep airflow moving, which detracts from the ideal mold growing conditions usually present in attics.
  • Check Window and Skylight Seals for Leaks: Some attics have windows or skylights. Make sure that the seals surrounding these windows is in good condition at least twice per year. It is also recommended that these spots are checked after heavy storms.
  • Inspection Your Attic Regularly: You don’t necessarily have to hire someone to your home for an inspection. Just grab a flashlight and check the attic space at least once per season. This way, you can notice any slow leaks or mold growth, and track any changes over time.
  • Fix Roof Leaks ASAP: This may seem like a no-brainer, but it’s worth mentioning. As soon as you notice a roof leak, fix it as quickly as you can. Water damage doesn’t take long to develop, and mold is not far behind the problems that water damage brings.


Preventing attic mold takes some diligence and attention, but a few minor tweaks here and there can save you a lot of hassle and headache in the long run.

If left untreated, attic mold can become a serious problem, spreading to other parts of the house and causing odors, structural damage, and unhealthy living conditions. It is recommended that you treat mold as soon as you notice its presence.

Mold can be challenging to thoroughly remove from any home. Fungicides and specialized chemicals are usually required in order to kill all traces of mold. Many times, insulation must be removed entirely to prevent further spread or cross-contamination to other parts of the home. Cleaning attic mold is best left to the professionals, as DIY techniques unfortunately do not remove all traces of mold and can lead to mold regrowth.
