Wood glued over flat roof - will this last?

[Thusha]

Our builder told us he used glue to attach treated wood over flat GPR garage roof in order to extend our pitched porch roof over front of garage (he built the frame in wood and glued it over the GPR flat roof). Is this acceptable, to use glue to attach wood? My concern is that its not strong enough and our new pitched porch roof would fly away in a storm from the glue giving away

Potentially yes, it could lift.
Why didn't he use any mechanical fixings?
Plates, brackets, straps, etc. are cheap enough.
Is it too late to remedy?
Have you got access to it?

Hi,

it’s still fixable/ they have access. can you see in the picture the wood glued to the flat roof? What can be done to fix it more securely? I don’t think they should drill through the roof and create holes that can cause leak? Unless it can be sealed after drilling hole n screw with something on top? Let me know options. Thanks

Sorry, I can't see what the fixed with wood glue.
Can you circle it in the picture please?

It should be fixed/ screwed down through the roof and the grp run up from the existing roof and under whatever cladding they are using for a finish.

Did they run out of screws?
Did they check in the saddles outside you front door?

you say wood glue what exactly does he mean ??
wood glue can be pva but a large container off pva is not wood glue it is more diluted and off minimal strength in general it will come in 500-iL bottle costing around £5-10
if its 5L and a builder has it its not wood glue
