Attic Mold – The Nitty Gritty

 

Most of the people we talk with are unaware there might be a mold problem in their attic. After all, it is not usually considered part of the living space and we don’t often go up there. When a property goes on the market for sale the potential buyer will usually have a home inspection done and this is when mold in the attic is often discovered. The potential buyer and the seller then usually negotiate to determine which party will take care of the attic mold and then they request a professional company to provide a proposal or estimate to fix the problem. This is when a company like us comes into play to inspect the attic and provide a proposal for a solution to the issue.

 

What is Mold?

Mold is a living organism and needs both a food source and water/moisture to survive. Building materials such as wood and drywall are an ideal food source for mold. Over time the mold will continue to consume until there is nothing left but rotten material. Mold is nature’s degrader.

There are tens of thousands of different types of mold but some of the most common mold species we encounter as a professional mold remediation company are: Penicillium/Aspergillus, Cladosporium, Chaetomium and Stachybotrys (more commonly known as black mold).

 

Common Causes of Attic Mold. 

Common causes of attic mold are typically issues with ventilation, such as:

  • Blocked Soffits
  • Blocked Soffit Vents
  • Improperly Vented Bathroom Power Fans That Exhaust Directly Into the Attic.
  • Roof Leaks
  • Inadequate Attic Insulation

What you need to remember is that mold is only a symptom of the problem; the real problem is moisture or trapped moisture.

We Have Attic Mold, Now What?

Generally a little mold in the attic is not a major problem and can be cleaned up easily. However, if left unchecked for a long period of time the mold in the attic could get so bad that it may involve a complete roof tear off and remediation of the remaining roof structure before a new roof can be put back on to fix the problem. Obviously this can be quite costly.

If left unchecked a moisture problem will likely turn into a mold problem. Under the right conditions, mold can begin to grow within a 24 hour period. If conditions in the attic are favorable for mold growth then the roof joists and roof sheathing in the attic will often show signs of discoloration. Sometimes the mold growth is light and spotty however, the mold growth could also be much heavier if the root cause of the mold problem is significant enough.

As an example, when bathroom power fans exhaust directly into the attic during the colder months, moisture in the air of the home from showering etc. can be transferred into the attic. The moisture in the air can then condense on the colder surfaces of the attic such as the roof joists and roof sheathing, causing mold to grow. Combine that in the warmer months when the humidity is naturally higher with inadequate attic ventilation, blocked soffits and/or soffit vents and the mold problem could escalate quickly.
