If I hadn't seen this with my own eyes, I wouldn't have believed it - my dirty moss-covered 18-year-old tiled roof transformed into a smart grey modern tiled roof within hours, thanks to the hard work of Max and Jake and the very effective cleaning methods used. No climbing on the roof, no high-pressure jets, and, most importantly, no damage to tiles, pointing or gutters. They also did my conservatory to the same standards, and then cleaned everything up afterwards. My wife and I are absolutely delighted with the results. Five stars from us!
