I'm in the process of renovating my garage. There was a 1 in. gap due to rotting wood where the roof shingles meet the fascia (part where gutter is attached). The discolored wood is near the gap.
A few joists are the same color as well. I sprayed with Vinegar and soap - nothing really changed. I avoided using bleach due to the wood being porous. Any idea of which type of mold this is? Does the wood need to be replaced or can I use some type of cleaner (concrobium, borax ect). I was also thinking of scrubbing the wood w/ vinegar & baking soda again, wiping with microfiber cloth, spraying concrobium and then painting over with an anti microbial primer sealer.
