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?

  • Surely you can spray the fungicide and paint yourself. Do you need a mold abatement certificate for any reason?

  • The buyer has not asked for a certificate. In my state, mold remediation does not require special licensing. My contractor tells me he can do it for much less. He is at least a licensed contractor. It is a fairly large area.

  • Dry ice blasting will also remove it, but that would likely also require hiring a professional. Oct 30 '18 at 21:55

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.

  • The inspector said it was because the dryer vented into the garage. It actually just looks like dust. The vent is being rerouted.

    A dryer could do it.
