Hey guys. Quick question about these black spots on the soffits of a house I did today. It’s only in the back area of the house by their patio. I went over them once. Saw the spots. Took a picture then hit them again. They won’t budge. I tried scrapping one of them off with my fingernail and a key. They wouldn’t budge.
No sir. No mulch at all. It’s an open patio. It the lawn, a step and then the patio. And its only on a 12 foot section. I wish I would have taken a picture of the area.
Maybe the homeowner had some plant boxes on that area with mulch in them. Artillery mold/fungus shoots pretty far, a mulched tree 10 feet away will hit a house easily. Without going back and rereading all the info on artillery mold, I think it can shoot up to 20’.
There is also a chance if you look under that soffit that they might have some mold issues, happens with moisture and poor ventilation.
lastly is it a metal or a plastic/vinyl soffit. Some of the older stuff was metal and it does corrode over time.
