Attic Mold

 

Attic mold is very common and is dealt with by tens of thousands of families every year. Mold is a type of fungus found almost everywhere. It can be found in many different colours, but common attic mold is black or white. Molds thrive on moisture and reproduce by means of tiny, lightweight spores.

 

 

Common Causes of Attic Mold:

 

The attic is a separate space from the rest of the house and homeowners do not access the attic that often. Inadequate number of vents (1 vent per 100 sq ft) or blocked soffit vents (typically blocked by insulation) can cause mold formation.

 

Damaged or missing vapor barrier, which is more common for older homes.

 

Improper connection, damaged vent pipes or vents that terminate within the attic space can cause mold formation. Remember that venting must be done from the interior of the home to outside and never to the attic!

 

Moisture saturated roof decking combined with dark attic spaces is a perfect breeding ground for mold growth.

 

Leaky Skylights or missing chase wall insulation may also be a reason for attic mold.

 

Missing or insufficient amount of insulation or compressed insulation.

 

Prevention:

 

 

Cleaning Options:

Inside your house, cleaning of the mold may be done with Vinegar, Borax or Hydrogen Peroxide for small areas. However, attic mold removal is dangerous to do on your own thus it is highly recommended, that the mold removal in the attic is done properly by mold professionals, who will clean the area and will apply powerful antifungal sealers which will prevent the mold from growing back.
