Outstanding results! The only thing that could have made it better would be if it were free.

Chris and crew came to my home when scheduled and introduced themselves in a friendly, professional manner. They "shampooed" the roof of my two buildings without even taking a noticeable break. The exterior of the house and all deck and patio surfaces were flushed with water leaving no trace of the crude that was removed from the roof. I may be selling our home soon, and this roof treatment made the shingles look like new and therefore will potentially eliminate any negotiation related to the roof.

Very professional and knowledgeable on all the black stains on my roof. What a amazing transformation from my old roof to what now looks like a new roof. Thanks Diamond roofing for the great job. We will be recommending you to our friends!

I live in an area with lots of oak trees and my roof was looking really bad. I was a little skeptical, but decided to go ahead with a roof shampoo and it turned out great!! I'd have to say, it looks like new after the job Diamond Roofing did. Whatever cleaner they used didn't harm my plants and the crew was very professional....I highly recommend them.

They did an excellent job with a roof shampoo, removing all kinds of organic material including moss and pollen that was building up, and removing ugly black stains too. All without using bleach products or high pressure power washing that could damage the roof. Highly recommended!
