I've left it a number of months to post a review because on such a big (for us) expenditure, we wanted to see if the job lasted. It has, excellently so. We asked for quotes from a number of companies to redo our flat roof on our extension. We also wanted it converted to a warm roof. This company was on time and very helpful on the initial visit. We eventually went with them and they were incredibly professional, polite on site and did a fantastic job. They cleaned up fully. And they did the whole thing in a day. Scaffolding was sorted by them. Other than sorting out which day, we didn't have to do anything. The end result looked great. I've waited to review to make sure that nothing has deteriorated. Nothing has. Eight months on, it still looks great. The insulation made quite the difference to the rooms below and cut the need for heating. It's also much quieter when it rains. I cannot recommend them enough and, unlike some of the companies we requested quotes from, who either didn't reply, or pulled quotes within 24 hours, this company were professional from start to finish.
