Just over a year ago we had the flat roof on our garage replaced with
a fibreglass one.  The timbers were put down by the builder, and an
independent roofing company came along to complete the (very smelly)
task.

Unfortunately I don't think the builder made a very good job of laying
the decking, because we have quite severe puddling in places,
particularly just adjacent to the gutter.  I could envisage cutting a
shallow channel there to allow the puddle to drain away.  Can this be
done with a fibreglass roof?  I should mention that I think there's
Buckley's chance of getting the builder to fix it - he's had his
retainer long ago (by mistake).

Thanks

What sort of finish is on the FG surface?

It may be simply a matter of you getting a FG kit and laying a sheet
over the dips to level it up.

If its not leaking you might be better of just leaving it alone.

If you are going to build it up you'll need to make sure its bone dry
and abrade the surface after removing any aluminium painted coating.
Don't add more than 2% catalyst to make the resin go off quicker and
make sure any CFM is wetted out completely.

IANAE, so how do I identify an "aluminium painted coating"?  It is (or
was) rather a fetching blue colour.  It certainly smelled a very great
deal when the guys put it on.

In answer to suggestions above - the reason I am reluctant to leave it
alone is because my brother, who has recently qualified as some sort
of surveyor, saw the puddling and a bird standing in it, and said that
the the bird was eating some variety of small crustacean that
serendipity had placed in the puddle, and that the beak could damage
the roof.  Seemed unlikely to me, but not worth the risk.

I am tempted to build it up because there is a fall from one side to
the other, but the problem is that the substrate is not flat and
even.  So I'm minded to follow EricP and 1501's advice (crazy name, by
the way!) and build up the surface to "iron out" the bumps

"some sort of surveyor"? He doesn't seem to know much about strengths
of materials and likely effects of a birds beak.
I would forget it

Your choice of course!
