Single ply roofing follows NRCA guidelines, and a roofing subcontractor that does not read the membrane, the attachment, and the insulation is pricing the wrong system.
What a single ply roofing package sets
Single ply roofing uses membranes such as TPO, EPDM, or PVC over insulation, installed to NRCA guidelines and the manufacturer's system. The Division 07 specifications set the membrane, the attachment, the insulation, and the flashings the roofing sub must provide, along with the warranty system.
Why roofing scope is easy to misprice
The membrane type, the attachment method, the insulation, and the flashings sit in the Division 07 specifications and the roof drawings, not the title. A sub that misreads the system or the attachment carries the wrong material and labor into the bid.
How an AI bid agent reads roofing packages
An AI bid agent reads each roofing solicitation or sub package, identifies the single ply system under NRCA guidelines, and surfaces the membrane, the attachment, and the insulation that drive the work. The roofing sub prices the actual system.
You can see how the agent reads a roofing package in our AI bid agent demo for specialty trade contractors. It pulls the single ply membrane, attachment, and insulation scope so the roof is priced correctly.
