Most roof leaks aren’t solved by “more sealant.” Repeat leaks happen when the real failure point is flashing, seams, or drainage—especially on flat roofs.
The usual leak culprits
- Wall and chimney flashing failures
- Split seams on modified bitumen roofs
- Ponding water from slope/drain issues
- Clogged scuppers/gutters causing backup
- Edge deterioration where water gets under the system
What a real repair plan includes
- Locating entry point vs. stain location (they’re often different)
- Repairing flashing/transitions, not just the membrane surface
- Confirming drainage path and restoring flow at scuppers
