I have a customer who I've been working for for like 10 years, and then I didnt hear from him last year at all. Then he calls me in late February during a rare warm spell(60 F), and asks me to come and look at his gutters. Turns out his wife died of cancer last year at 55 years old.

When I get there on the roof, the real problem was all the moss! It had gotten so bad that it was covering a total of about 25-30% of the entire roof, and I mean it was thick! It wasnt just a little 2-4mm thick green covering on the roof, it was 2" thick in many areas! It was as bad as you'd see it in the forest on the ground. The back top roof was the worst, which cant be seen from the ground.

So I brought a pressure washer over and first sprayed it with bleach, then let that sit, then pressure washed ALL the moss off the roof, washing every inch of the shingles to remove the tiny, new moss that was starting to grow elsewhere in little 2-4mm wide spots.

When I got done, the gutters were completely overflowing with moss, and there were piles of it on the ground that I'd thrown over! Then I cleaned it all up and tossed it into the forest.

But from now on, I'll spray it occasionally with Oxy Clean or whatever to keep it down.
