If it was a prefectly flat roof, shouldn’t puddle…
There doesn't seem to be much of a slope. If there's a low point, the water will find it. The fact that it's puddling means that the slope must be smaller that the variations in slope, if you get what I mean. If you go inside and push upwards from under where the water is lying, the chances are it will run off, or find another low point.

if it were felt I'd be worried........
as it's ruybber should be fine.....
never understand why people dont fit insulated steel sheeting.....costs about the same and u'd get more than 25 years out of it....
plus u can do it urself.....

To be fair you can do rubber yourself. I've done three to date and would not hesitate to use it again.

when the garage was built over 40 years ag it had a 5" slope.
I wasn't impressed at the time nor did I pay much.
the then neighbour was a bricky and got the drive and foundation inc garage done at almost half price.
concrete was left overs from a building sight so rather than dumping the left over we had our drive done in 3 stages
at the time I only paid about £60 for the whole drive.
garage was built shortly after and all I paid was for timber and labour and a little bit for the other materials.
can't how much but was very cheap,so I didn't argue about the slope.
I did mention to the late neighbour about having a 10" slope but plans was already submitted then.
at the time council were very strict on planning permission.

Because a lot of domestic customers don't want there low level roof looking like a mini Costco, and never be worried over a full SBS felted roof if done correctly, i regularly drive by jobs i did almost 40 years ago and still there leak free. Like everything in life, there is a pork sausage and there is a pork sausage costing 3 times as much for a reason

all materials was new no left overs from previous jobs.
they had materials delivered. I watched them from time to time.
they use 18mm sbs boards. left overs I kept for myself.
no missed joints either(no gaps in joints.)
the Roof was done by Hartburn Roofers. I'm sure Alan knows or heard of them.
they came on the recommendation of others.
all I'm bothered about that it doesn't start to leak a few years down the road.
25 years warranty on it. I doubt I'll be around then if I am I'll be 97.

Trouble is with using offcuts rather than full sheets sometimes.
Mad idea but could you get to the underside and jack the roof boards up in the area of the sag, then slip some packs in between top of joist and underside of the OSB?

that's just what I was thinking.... fingers crossed the slope down the edge is better so the water will run over there and down?
probably only need a 2 or 3mm lift?

The joists are the existing ones though yes?
Current standards for flat roofs is to design to a 1:40 fall minimum. This means that allowing for site tolerances you should end up with min 1:60 fall which is sufficient to shed all water off it.
The major limitation in your install was the existing joists and party wall to neighbours garage too. Ideally they should have added firing strips to your joists and string lined / packed them as required to ensure an even deck.
I think you will have to look at the pending if their remit was only to address the roof covering replacement.

the issue has always been its a shared roof
unless next door is willing to do theres at the same time theres always a risk that it will leak at that joint
fitting furings well the best way is from the middle to the end to fit those length wise yes they can be fitted but that means the whole roof needs doing the same way and yet your back to the same trouble the shared joint in the middle
as goes for the water thats caused by your joists not the new boards fitters have just fitted and boarded as is
