Repair
Suitable for a limited failure with sound adjacent materials and manageable moisture conditions.
A low-slope roof can hold water near a blocked drain or a change in surface height. Water can also travel beneath the membrane before it appears inside. The leak location, roof layout and assembly condition need to be considered together.
A local membrane or flashing failure can have a focused repair. Widespread wet insulation, failing layers or unsuitable support changes the decision. Replacement makes it possible to remove damaged assembly and rebuild the drainage and details as part of the new roof.

The useful scope follows the water path and the material on the building.
Splits, punctures, failed laps and previous patches are assessed with compatible repair methods in mind.
Drainage outlets need clear routes. Tapered insulation or other drainage changes may belong in replacement planning rather than being treated as a surface coating issue.
Equipment curbs, parapets and penetrations interrupt the continuous roof field. Flashing transitions need sound attachment and compatible materials.
The amount and location of trapped moisture affects whether a repair, recover or replacement is practical. Concealed conditions may need further investigation.
Each option depends on the existing assembly.
Suitable for a limited failure with sound adjacent materials and manageable moisture conditions.
An additional roof assembly needs compatible, dry and suitable existing layers and compliance with the applicable limits. It is not a way to conceal wet material.
Removal addresses deteriorated covering, unsuitable layers and damaged insulation or support. The new system can include needed drainage improvements.
A coating does not correct a blocked outlet, roof slope or unsuitable support. The drainage cause has to be understood and addressed.
Occupancy, access, sensitive areas and equipment needs inform staging and scheduling discussions. The actual plan depends on the building and the scope.
