What do you do now?

A new project that was designed by a PE down here in the Sunshine State according to the FBC Hurricane high wind design, anyway the PE called for a frame constructed addition with a flat roof deck, he also called for a single ply roofing system over a vapor barrier and 1.5 ISO board with a 1/2 recovery board any way there the scoop The project requires a -69 neg pressure lift off Now after checking all of the Miami Dade roofing specs I can't find one that meets the neg pressure requirement I checked BUR, Modified TPO, PVC Foam and metal the pitch on the roof deck exceeds 1/4" per foot The engineer is pulling out what hair he has left and I'm chuckling away. Now if it was a concrete deck there would be no problem He could change the Plywood from CDX to Marine grade BC the probably use insulation and use a special fastening system which I'm not familiar with, my son told about the heat system that heats the membrane laps and heats the screws and plates assembly it seem no one down this has this robot If any knows the system please advise, and I thought my brain would get out of this roofing thinking lol

Thanks Mike, my son told me all about it, it seems that he has been using the system for the last 2 years see what happens when you get away from this industry my mind keeps thinking the good old BUR lol I have changed my thinking about TPO and PVC and Epdm is starting to take hold , but when I started we only used BUR coal tar an asphalt,my brain was against ac of other products This year I will hit the 75yr mark perhaps my brain will make up for all that I missed lol Thanks again

Darryl,

do a google search for "rhino-bond".

Everything you ever wanted to know about using robots to heat up membrane to insulation plates can be found there.

Couple of my guys doing it here.
