There was very little algae and a few spots of moss. My roof is old but in acceptable working condition and in no danger of leaking. I sprayed it evenly saturating all of the shingles with a 3% bleach solution with some dawn soap as a surfactant. Supposed to rain all weekend so I will take pics next week to send back with a statement of work performed. Seamed to me like they're busting balls but sometimes it's just better to appease and move on. Would be more annoyed if I had to pay a roofing company as it would cost close to 1k where I live.What did you have to wash off? Goats and pigs and stuff?
