Tomlinson Roofing, a local SE London outfit, just did an excellent job re-roofing my property in East Dulwich. It's a small family business and they did the work themselves - no sub-contracting the job or anything at all dodgy. Their estimate was fair, communication excellent (plenty of updates on progress) and the work was first class. Nice people & I can't imagine a better experience for such a major renovation. They're members of all the appropriate trade associations (WHICH Trusted Trader, Competent Roofer etc) and their other reviews look 100% positive. I would definitely employ them again. Ray
