Mold in Attic

If you are reading this then chances are mold was discovered in your attic.  Whether it was discovered when you were buying/selling your home or you just happened upon it the number one thing to remember is: DON’T PANIC!!

Mold is Everywhere. Even in Your Attic. Especially Your Attic.

Mold is everywhere around us and the majority of the time attic mold is nothing to worry about.  Then, what’s the big deal?  Mold in your attic is slowly eating away at your home resulting in:

  • Shortened shingle life
  • Weakened decking material
  • Rafter/truss failure

Why does mold grow in Indiana attics?

Mold grows in attics due to a moisture source. Since mold and mold food is everywhere mold spores are just waiting for moisture. When moisture is added to a spore its similar to a seed that is watered. The mold grows roots and a body which is collectively called mycelium and eventually fruiting bodies called sporangium which have spore sacs. These mold sacs burst when disturbed ensuring the continuation of the colony of fungus. Which is why there is a need for mold remediation.

In the State of Indiana, attic mold moisture sources are normally one of these four:

Active Roof Leak

This is a direct leak from the outside and usually the most obvious.

Bathroom Fan Ventilation Mold

Poor Ventilation

Poor ventilation is the most common in Indiana. Many Indianapolis area homes have the right amount of vents but they are blocked with insulation. Don’t be fooled by baffles (cardboard or Styrofoam pieces at the eave of the home inside the attic), most insulation companies put them in after and they are plugged as well. If your home has no venting or insufficient venting then baffles are needed only after eave vents and/or ridge vents are added.

Bathroom Exhaust Fan

Indiana Building codes change over the years. Your exhaust fan may vent to your exterior if your home is newer, or if it has been fixed over the years. Prior to code changes in the early 2000’s home builders were allowed to exhaust fans in the attic. This elevates moisture so much that even a working ventilation system cannot stop mold growth.

Mold from Poor Ventilation

General Central Indiana Humidity

A home’s humidity comes from many sources, showering, cooking, a damp basement, etc. Your Indiana home breathes from the bottom up; this brings all that humidity right to the attic. Mold can grow as soon as the humidity hits roughly 70% which is normal in a climate like the one in Central Indiana.
