We had a double story extension built 3 years ago with a partial flat roof for a balcony coming off our last bedroom measuring 3m x 4m x 3m the material used was felt and then stabbed over the top this has repeatedly leaked into our kitchen when bad weather comes - our builder has already taken it up 're felted and laid slabs down with concrete rather than geofix to try and improve but it has since leaked again. The builder is now saying we should look into a rubber roof and we should be paying for this out of our own pocket as he is blaming the architect for the design and not his poor workmanship . Where do we stand with this? Who is to blame? And who can help us? Many Thanks
Are you a tradesperson and able to answer this question?
I don’t think it should be down to you to pay for all of the work maybe partly towards it the problem roofers have with leaks it is a process of elimination so changing it again might be your best option or might not be I think getting a second opinion off another trademan to come and view the work and see what they have to say would be the best thing to do.

I don’t think you should be fully responsible for a replacement product on your flat roof however if surveyed by fresh eyes and they see defects in the installation of the felt used then the responsibility lays at the Roofer’s door.
On the other hand there is resins that can be used to tank over the original system if structurally sound that comes with a 25 year guarantee so a new rubber system sounds a bit extreme,I’m pretty confident a professional roofer could survey and source this issue and rectify accordingly at a smaller cost to a brand new system being installed.
In my own professional opinion there is better options for flats roofs than felt these days so the architect involved may have a question or two to answer.
Felt works are always the cheapest option normally to use on a flat roof.
