Attic Mold – A Common Problem in Portland area homes.

Attic mold is very common in Oregon and throughout the Pacific Northwest. The problem occurs when warm humid air from the interior of the home travels into the attic and reaches the cold surface of the roof decking.  This rapid temperature drop leads to condensation, and in many cases, mold growth.  The problem is most often detected in newer homes, as these homes are built with materials such as OSB and plywood that are much more conducive to mold growth.

Common Causes

Improperly vented fans, roof leak, inadequate ventilation, and wet building matierials all contribute to attic mold.

Health Effects

Thankfully, attic mold is typically not associated with negative health effects.  This is due to the airflow patterns in the house, especially the stack effect.  The stack effect is the upward movement of air through a home, primarily caused by the rise of warm air.

Attic mold can affect the health of individuals within the home. At Environix our technicians are able to test for mold in the home to determine if there has been cross contamination. If you are interested in having this testing conducted please call our office.
