I am having a problem with mold on my roof, googleing provides many remedies and the most common one is plain ol vinegar. I don't have a problem on on roof and a hand sprayer but the other roof is too steep to walk on and would require D-rings and climbing apparatus and I don't want to be a statistic so I am think something that would work with the pump on my power washer or garden sprayer.

Thoughts ol wise one?
