Flat roof not level. Roofer confused

[Mojo12345]

Hi everyone looking for advice I had a roofer come today start work

from my previous posts some may remember I had a leaking roof, a window was too low and causing difficulty getting a seal between roof and wall

I have replaced the window making it easier to get an upstanding seal but there are 2 parts were the osb boards are not level, the roofer is confused as to how to get the boards level.

The water is ponding where the dip is thus creating a leak, is it important to get the boards level as this will allow the water to flow into gutter or is it ok to let the water pond

any advice help would be great thank you

He’s coming back tomorrow to continue work

there are lots of glaring faults in your original flat roof construction.
others will i'm sure help you but i wont go any further after this.
just one thing - why has the roofer started doing hot felt work when he doesn't even know how he will deal with the unequal levels?

MW Roofline in a 21 september #12 post advised you lift the roof down to rafters and start again - a bit late but i agree.
even the penetrations might mostly have been eliminated by re-routing etc.

The roof could dip more than a dippy person eating chocolate dippers on a big dipper, but the felt should still not leak.
