I am sure he will understand that!
You ( the Owner ) can fit the vertical flue terminal through the roof if your installer agrees but he MUST do the connection to the rest of the flue to the boiler. ( Regardless of what he says! )
I would welcome that as it would absolve any responsibility for leaks from me! He might as well.
The roof weatherproofing is quite simple really but its something that many boiler installers seem to get wrong and then it leaks.
