Is mold in my attic affecting my home?

For a more detailed answer see Mold Remediation in Attics. Due to the general movement of air up and out of the home, mold in the attic is not likely to affect the interior of the home. Mold growth in the attic is generally caused by condensation on the roof decking unless an apparent leak is present or ice damming has occurred. The conditions that lead to the mold growth should be corrected and the mold treated to prevent future growth.
