Single-ply membrane
TPO, PVC and EPDM use different materials and joining methods. A compatible detail matters more than the color of a patch.

Get help with leaks on a flat or low-slope roof in Gentry. Start with a compatible repair and a clear view of the affected layers.
On a low-slope roof, water can move below the weather surface before it reaches the interior. A stain near a wall may originate at a seam, a curb or a roof edge farther away.
The repair has to address the entry point and the condition of the assembly underneath. Covering the nearest visible split leaves uncertainty if wet insulation or another opening remains.

Identify the existing system before choosing the repair materials.
TPO, PVC and EPDM use different materials and joining methods. A compatible detail matters more than the color of a patch.
Cap sheets, flashings and prior repairs need to be assessed together. Splits or blisters can point to conditions beyond a surface coating.
Panel seams, fasteners and equipment curbs each create a different repair task. Mechanical unit failures and roof-flashing failures require coordinated but distinct work.
A drain needs an open inlet and a sound connection to the roofing. Debris can block the inlet; failed flashing can leak even when the drain is clear. A low area in the roof can hold water away from the drain entirely.
Those conditions should not all be answered with a patch. Drain maintenance, detail reconstruction or a larger slope correction may be the work that actually changes the outcome.

Access, noise, odors, interior protection and the location of the work determine how it is scheduled. Do not assume zero disruption; the plan needs to fit the building’s actual use.
The building location, where water appears, whether it is active and any access restrictions are useful. If you know the roof system, include it. Do not climb onto the roof to identify it.
No. The membrane-to-curb connection is a roofing detail. A mechanical leak or equipment fault belongs to the appropriate service trade. The cause should be identified before work is assigned.
