Commercial Building Retail Business – Flat Roof/Re-roof Duro-Last Fully Adhered Roofing System Duro-Last is a factory-welded single-ply thermoplastic roofing membrane. Duro-Last membranes are measured, ordered, and custom-fit to each individual roof. This way, many seams can be factory welded in a controlled environment. Before a Duro-Last job is finished, it is inspected by quality assurance representatives of the manufacturer (not Grell Roofing) to meet exhaustive specs, and in order to carry one of the best warranties in the industry.
