Home inspector found mold in roof under sheathing in my garage. Mold professional says they spray a fungicide to kill it and then spray with a tinted paint. Extremely pricey! You cant clean it off because of the roof nails everywhere. Is this the only way?
Sounds like you’re the “seller” and the “buyer’s” inspector found the problem.
In real estate sales, I think it is better for the seller to reduce the asking price and let the buyer “fix” the problem. If you try to fix the problem, I can guarantee you that it won’t be good enough and you’ll be re-negotiating the cost and repair later.
I don't know if they will let you do it since it was found on an inspection but I would spray the area with 3% hydrogen peroxide and water mixture this will kill the mold if you want to seal it after dry regular paint should encapsulate the wood but if you use a marine grade anti fouling paint or a paint where you can add the fungicide that would do the trick. My concern would be why was the wood wet painting may trap moisture from a leak in the wood making the problem bigger later on.
