I found Russell from Which and am so glad I did. I have now used his services 3 times with each job getting bigger and bigger. 1. I had a leak from a new extension in my house and he immediately new where the issue was( the chimney top cover and lead installed by my builders). We fixed a time/agreed a price and job was very well done. What I liked is that he said he would re-use the existing lead to fix the issue where other roofers wanted to charge me more and said the existing lead was unusable. (2014) 2. My dad has a couple of property and both had leaks- he fixed both very quickly and efficiently. One needed scaffolding which he got installed and taken away on the same day. Great job and glad to say we have no issues (he did this at the beginning of 2015) 3. We have just moved house and needed stacks removed, then we decided that we wil have the roof replaced instead. Russell and his team had my complete stacks removed (3 story house) inside and out, and placed a new roof on in 5 days with a rain day included. He ensured that the place was tidy by putting plastic sheets down and made the place clean before leaving. Scaffolding removed, all rubbish removed- sent me pictures off the progress and called me every evening to let me know the plans and finish date. Great professional service and and honest roofer that you know will honour the agreement in place. Never asked me for money until job was done - sign of a good tradesmen. I also know he does a lot of work in dulwich - search his company in the east dulwich forum for more info like I did- one thing is that he is very very busy so sometimes can be difficult to get hold off but worth the wait!!! Hope my review helps
