We have a large (4m long by 3m wide) lean-to conservatory with a glass roof with aluminium/plastic glazing bars. Because it is so long the glass is arranged into two pieces per span (2x2m) with the two panes adjoined by a joining or "Muntin" bar.
A bit like this:

I've noticed that the roof leaks in a few places when it rains heavily and suspect the issue may be these Muntin bars. It is a poor design as when the rain runs down the muntin bars act as a bit of a dam and water can build up there.
I've had a couple of quotes from different people to do either:
a) jet wash the roof and seal externally around the muntin bars/anywhere else prone to leaking
b) replace the muntin bars, reseat and seal the panes with silicon in the muntin bars
Option b) sounds like the more thorough repair - my reservation is that because this is an inherently poor design, even if it is a good repair, will it leak again fairly soon after? Whereas option a) is more of a bodge, it may actually end up repairing the leak better and for longer.
Looking for some advice or if anyone has had any experience with similar?
Cheers.
