Leaking around new boiler flue- who is responsible?

Clive709

Hi, hoping for some advice as we're not getting anywhere with boiler fitters. So a year ago we had new oil boiler installed by reputable company and they said best place for it was in corner of our porch and they would cut hole in roof for vertical flue. We have never had any trouble with leaks prior to this. However after heavy rain last summer water was coming in via the outside of flue pipe. We contacted the company who came out and put sealant around outside where flue meets tile. This reduced ingress but trickles were still visible in heavy rain. We have since had them out 3 more times and last time they lifted up tiles around flue and put down in their words " a sh*t tonne of lead". This seemed to have done the trick until another heavy downpour today and once again water pouring in down outside of flue. I have no idea if water getting onto boiler itself and obviously concerned about water damage in roof cavity. I realise the company are not roofers and they obviously don't know how to fix problem they have made. The last workman seemed to be implying the pitch of our roof is wrong and therefore not their fault. But surely if this was case they should not have advised the installation of the boiler flue there. I am thinking we need to get outside roofers in to sort it out but should we pursue boiler company to pay or just accept and pay for repairs/remedial work ourselves? Thanks for any advice

IMHO, the company should install the flue so it doesn't leak. It's no excuse blaming the roof pitch. 
Can you put an external photo on?

Thanks for your reply. I too thought it was their responsibility and so far they have been out when called and tried to bodge a repair (no charge) but It's getting ridiculous now. Photo attached.

They are responsible for the installation, so they are responsible for it leaking. Do you have home insurance? If so, do you have Legal Expeneses Protection? If so, call the Legal Helpline provided by your insurer.

Shouldn't need mastic between the tiles - Looks like someone has been way too enthusiastic with the stuff.

The tile closest to the verge (top row where the flue pokes up) appears to be cracked. In addition, it doesn't look as if it is seated properly on the tile next to it. Wouldn't be at all surprised if water is getting under that tile and tracking the short distance to the flue.
