An architect or planning consultant is what you need. From a roofing point of view.. If flat, have you considered something sustainable like a green or blue roof covering - Solar perhaps. These can be great living spaces too, in the summer of course! I would generally always opt for a pitched roof where possible, they're less problematic and more aesthetically pleasing (in my opinion). You could consider a lightweight flat to pitched conversion - there are some terrific systems available these days.

I'm sorry to say, but this is classic. And, not at all your fault. Horrible situation 😔 The job of the Architect is not simply to design but also to project manage and administer a contract for delivering the project. You could also have obtained this service from a freelance QS or PM, who would have carried the process forward for you, from where the Architect left off. With technical roofing applications, it's imperative to obtain a spec from the manufacturer and not the contractor - If you ask 3 contractors, you'll get 3 opinions and not necessarily something that meets the manufacturers guarantee requirements. You needed an approved contractor and preferably a single point guarantee with the manufacturer. I know these are available with this type of system. A contract, with the roofing contractor, which detailed all of the nitty gritty in terms of spec, delivery, programme, guarantee, costs, variations, liabilities and payments - Did you have one? This sounds laborious and a bit corporate, but unfortunately this is the reality in today's construction industry. This is also where a QS, PM or Architect could've added some value. If you need someone to do a quick review of the paperwork, to see if you have any claim against the original contractor, before you compromise that opportunity by instructing another - then I'd be happy to take a look.

I would suggest it's as a result of the party wall and gable both sitting slightly higher than the rafters. Gives the illusion that the tiles are running downhill into the dormer. They're probably not.

I'm a UK based quantity surveyor and project manager with an interest in traditional restoration and sustainable new build. I'm here to follow interesting projects, provide input where I can and generally keep up to date with build trends and new ideas.
