I had my roof cleaned in September 2017 by Dave. I had received an estimate to have the roof of my house (mostly discoloration, some moss) and detached garage (covered in moss) cleaned. Dave responded quickly and came within 2 days of my initial request. I noticed a change in the roof of my house immediately, and saw change in the small amounts of moss over the next few weeks. I was very pleased with the roof of my house and how that was cleaned. However, I noticed no change to my garage roof. I reached out to Dave in late October to see if the garage had been missed. He responded back within 2 weeks (it was the off season) and asked that I send him a picture of the roof and told me he would take care of my roof first thing in the spring. I emailed him in early May and early June asking that he come back to wash the roof and have not heard back. I would love to be able to give a great review because I had a good experience up until this point, but I would like to receive all of the services I was promised.
