Ralph and his team was a lifesaver for us. He came within hours although job was created via insurance company for next day and repaired the leaky roof. He changed few tiles free of charge, even i offered him reimbursement. He is honest guy, deal start till end very professionally. Thanks a lot, Ralph.

Report
We were suffering from water ingress from a flat roof balcony. Ralph Johnson visited our property to investigate and diagnosed the problem in under an hour. The remedy was agreed and the work was completed within a week. Ralph and team arrived at the day and time promised, completed the work in a professional manner within the agreed schedule. Finally they left everything clean and tidy after completion, plus I received a courtesy call from Ralph two days later to ensure my satisfaction with his work. A professional company that I would happily recommend.

I used R G Johnson to repair some storm damage we received to our roof. I had made various enquiries in the local area and every time R G Johnson were mentioned as the company to use. The team arrived promptly and were very friendly and professional. The work carried out was great and also the aftercare was also very good. I would highly recommend RG Johnson For any roofing repairs/work that needed doing.
