The attic is one of the most susceptible areas to mold and unfortunately, it can be quite challenging to determine the common causes and source of mold. However, when undergoing a mold inspection, our team typically finds that same sources of mold growth in attics.
One of the most common sources of water intrusion in the attic is due to roof leaks. Inadequate roof repairs, improper flashing, deteriorated rubber boot flashing and when the roof is beyond of its lifespan are some of the leading causes of roof leaks. Both water damage and mold growth are the two major results of a leaking roof. By having your roof annually inspected, you can prevent leaks and reduce your risk of mold growth.
Improper Roof Ventilation
One of the most conducive conditions to mold growth in attics is the lack of proper roof ventilation. If there is poor ventilation, there will often be elevated moisture conditions. If insulation is blown into the attic and you do not prevent the insulation from blocking the soffit vents, this also leads to mold growth.
Kitchen & Bath Exhaust Vents
Often times, exhaust fans are not vented toward the exterior of the home. When the exhaust duct has been separated, the exhaust air heads directly towards the attic space. This in turn contributes to microbial growth.
Lack of Attic Insulation
Mold growth in attics can spread quickly if there are not proper levels of insulation. If an attic is missing insulation, air movement will rapidly increase and cause condensation on cold roof sheathings. The condensation then becomes a catalyst for mold growth. Make sure you have complete coverage throughout the attic.
Especially around exhaust fans, lights and speakers, unsealed openings in the ceilings let warm air into the attic area. Sealing these up are one of the major preventative steps you can take to limit mold from spreading.
Although the attic is not considered a living space, if mold is in the air then there is a huge risk that it could spread throughout the home.
