Professional Plumber on the Roof

I was looking to install a rainwater catchment system and went to the tank supplier's website to look for registered installers. I came across Plumber on the Roof (who was an accredited supplier). What an amazing SME this company is! The owner (Devon van Laren) is friendly, professional and delivers first-class work in the plumbing business. Not only did he install a neat and efficient system for me, but he was also accommodating to look at other plumbing issues I had. These have all been repaired for very reasonable amounts of money and I highly recommend this company to anyone who is looking for professional plumbing services.
