I recently inspected a home that had a large amount of roof fungus on it especially around the intersection of the garage roof and the second floor wall.
When I went into the garage I noticed that the framing lumber had a black coating on it. There was some on the roof plywood, sidewall plywood sheathing and the studding.
When I saw no ventilation I began to worry about what the substance may be.
I went into the second floor attic and saw the same thing. The attic was small in volume, had 2 gable louvers of adequate size and a functioning attic fan.
When I rubbed my hands on the framing lumber the black substance came off on my hand. I scraped it off the ridge board where the was a heavy deposit and there was no damage to the ridge.
The house is 42 years old in South Jersey.
BTW the owner who I was doing the work for had his friend there who is a mold remediation contractor and he said it is not mold.
After I left I started to wonder if the roof fungus could invade the attic and if it did, would it be a health problem. Could the attic fan draw the fungus into the attic?
I checked some websites but I did not see an answer I thought fit my observations. Your thoughts please.
