A defined membrane defect
A compatible patch or seam repair needs suitable clean material and a sound connection. The repair method follows the actual system and manufacturer requirements.

TPO roof repair and replacement decisions start with seams, flashings and the condition beneath the membrane.
Free roof inspections. Repairs, replacements and commercial roof help.
TPO is a thermoplastic single-ply membrane. Its sheets are joined by heat-welded seams, and flashing connects the field membrane to curbs, drains and penetrations. A localized open seam is different from widespread surface deterioration or wet insulation beneath it.
We examine the existing membrane, its attachment and the adjoining details before choosing compatible work. Roof traffic, rooftop equipment and perimeter transitions help define where the investigation concentrates.

For the work beneath a new covering, see roof replacement and its deck, flashing and ventilation scope.

Wet insulation and damaged deck cannot be fixed by welding a patch on top. The affected layers need evaluation and correction.
Attachment, insulation, drainage and perimeter details form the roof system. Replacement scope needs to resolve those relationships around equipment and outlets.
Area, membrane thickness, attachment, insulation condition and tear-off drive the scope. Tenant entrances and equipment access affect staging and coordination. A residential shingle rate does not price a TPO project.
A roof walk helps establish whether the issue is concentrated or the roof needs broader work. Coating suitability is product- and roof-specific, with adhesion and underlying condition resolved before restoration.
Commercial flat roof repair
No. Other membranes and coatings can look similar. The existing system must be identified before compatible repair materials are selected.
