Who's job is it....?

[KaysProperty]

Hello, I'm new here and hoping someone can give me some advice.
I'm a letting agent and one of my properties has a conservatory with a flue going through the roof. The roof had been leaking around the box on top of the flue and the landlord has just paid £1000 to have the roof repaired but it still leaks around the box on top of the conservatory panel where the flue goes through.
The repair folks are saying that they can't touch anywhere near the box due to gas regulations and that it should be the gas engineer's job. The gas engineer says he's not a conservatory repair man and wouldn't know what to do.
Is there any reason or regulations why the conservatory repair guys can't touch the roof panel with the box on top? Can they just turn the boiler off when they remove the panel, re-fit it and seal it, it that's all it takes?
It has taken ages to find a company willing to repair something they didn't install and now that it is still leaking both tenant and landlord are starting to jump up and down.
I'm no expert in either field so any advice would be appreciated!!

Gas man should work with the roof man.

Some gas men can do both jobs.

How is that ever going to seal, no brackets on flue, expansion and contraction of poly roof. Looks like a lead roof slate.

Proper job would have bee n to move the boiler.

Probably a dektite retro fit boot flashing or something similar would work

Without seeing from above its not possible to know what they have done -it needs more than just the poly to seal to from above I would say.
