September 21, 2016 - We have battled with moss on our roof for 20 years. It's now 4 months since Quality One came and cleaned and treated the roof and it still looks immaculate. I had reservations about the bleach mix used near my plants, but they hosed everything down and I've had absolutely no problems. I have no hesitation in recommending these guys - super friendly, hard working and great support from Mike.
