This is what is known as the "Command Voice" when writing specifications.

Part 3 EXECUTION:

Spread adhesive with notched trowel

Generally less is more, in this case its downright cryptic

Thats Better.

Yes, Install a fully adhered low slope (waterproof) roof system above the carport with a properly designed structural deck, then install sleepers and a deck system above the membrane roof. Rail details should be round so they can be wrapped, and counterflashed.

EPDM or PVC will work. So will BUR or Modified but flashing will be a bit more involved. Small job, so if EPDM strip in seams. install blow-out patches on all T and 4 way joints.

My Personal favorites for this type of project would be Fibertite, or Sarnafil. Very good thermoplastic membranes with a very long history of performance. The benefit to a heat welded membrane is how they lend themselves very well to flashing details.

You will need a manufacturer approved commercial contractor, and it will not be cheap, but it will probably be done right IF you have the right details.

You can use EPDM too, and the contractor base is much larger, and there are some residential guys that do EPDM but you asked, so I answered. I like Firestone EPDM because it is pretty clean (Talc free) right off the roll because they have a very large production facility with huge curing racks.

Success is truly in the detailing with low slope roofing.

All three of these membranes are good, proven products, and any warranty you get on the material should be secondary. You need a good, experienced low slope contractor and a good design for success. Not a piece of paper with a gold scalloped design around the edges.
