Yes, it could be. Although there are no health problems directly linked to attic mold, it can lead to flares of allergies and asthma. Luckily, attic mold rarely finds its way into the building because of the ‘stack effect.’ This refers to the upward movement of air currents in your house. When warm air rises in your home, it reaches the attic carrying the mold spores. From here, they are eliminated through the venting, which means that they do not get to affect the occupants of the home. Since these movements are not likely to be reversed, most households are safe from attic mold. If the attic mold finds its way into your house, however, it could pose some health risks.
