A repair needs a clean, suitable surface and a product-specific connection. The existing membrane and any old coating must be identified before selecting materials.

TPO repair and replacement planning for Gentry buildings. Understand the full assembly behind the white membrane.
TPO is a thermoplastic single-ply roof membrane. Sheets are joined with hot-air-welded seams to create the weather surface. The field of the roof is only part of the job; seams, edges and openings must remain continuous around equipment and walls.
A TPO project also includes the attachment method and the insulation or coverboard beneath the membrane. Those choices need to fit the deck, building requirements and selected system, not just a preferred membrane thickness.

A curb lifts rooftop equipment above the field of the roof. Membrane must rise up its sides and form durable corners without leaving water a route behind the flashing. Mechanical fasteners and terminations need the right placement for that detail.
Service activity can damage a nearby surface or introduce new openings. Walkway protection and trade coordination should be addressed where equipment creates regular traffic.

The current membrane condition determines whether a localized repair is practical.

Wet insulation does not become sound by covering the top. The affected assembly needs to be defined and addressed.
Widespread failure or an unsuitable existing assembly can make commercial replacement planning more useful. Drainage and perimeter work belong in that discussion.
Reflective roofing can affect roof surface temperatures, but energy use depends on the building, insulation, equipment and operating conditions. No bill savings are promised here.
Necessary service access must follow the system requirements and protect against punctures. The work plan should address service routes and walkway protection near equipment.
No. The product, assembly, installer eligibility and offered terms differ. Read the warranty distinctions before treating a coverage term as a service-life guarantee.
