I had a new roof fitted earlier this year by what I thought was a reputable company. I did a lot of research before choosing who to go with. Everything went fairly well although they did try to squeeze more cash out of me by saying my chimney stack needed repairing. Had lots of discussions and I decided the chimney stack was fine. It had not caused me any problems prior to the fit and I didn't see it needed anything doing.
The job was finished quickly and everything seemed really fine. I paid promptly but couldn't get them to provide me with a receipt or a copy of the guarantee despite numerous emails. A few weeks later, during a particularly heavy storm, we noticed there was a leak in the roof and quite a lot of water had got in. It was not where the 'damaged' chimney stack was, in fact, it was on the opposite end of the roof.
I contacted the company, they sent a bloke out who took a photo of it from ground level and the company decided that the leak was being caused by my neighbour's chimney (not the one they'd tried to fleece me on). I queried how on earth they could make that assessment from a photo taken on a mobile phone and I wanted someone to come out and find out exactly where the leak was coming from.
I got no response so I compiled an 8-page letter with photos of before and after. Zooming in on the photos it is clear that the tiles at that point have not been laid flush and the old lead flashing has been re-used and looks to be cracked in places. This is exactly at the point where the water appears to be getting in.
I set out a list of things I want done starting with an inspection of the roof to find out where the problem is. I sent the letter and got the reply 'It's your own fault for not getting your chimney stack fixed'. I'm struggling to work out how they think a chimney stack on one end of the roof can cause a leak at the other end?
So I'm looking for advice on where I stand and what to do next. I've kept my tone polite and professional but this guy is an Alpha-male Neanderthal-type and I think he will do anything to get out of fixing it. What options are open to me and where do I stand legally?
