Sanity Check this flat roof replacement tender package? Looking for feedback before sending to contractors.

[AbuBella]

Hi all,
I’ve written up a detailed tender package for replacing a multi-part EPDM/rubber flat roof on a residential block that I live in after doing informal inspections with roofing contractors. There are issues with pooling, structural degradation, and signs of condensation damage due to poor ventilation.

I’d really appreciate some feedback on whether the spec makes sense, whether I’ve written anything stupid, and if you think roofers would realistically respond to this level of detail.

I'm also looking to invite some quotes from surveyours to give me detailed specification of the condition of the roof, and give me a scope of works, but really don't know if that should be necessary as I'm looking at stripping down the whole flat roof.

I have gathered the list of roofers myself, anyone know any forums or groups of roofing contractors that I can share this with to get some more quotes in?

It looks OK.  I would ask chatgpt to redraft / make suggestions.  How may m2, what thickness insulation and why EPDM?
