Common failure points
Open seams, aged flashing, pipe penetrations, perimeter edges, and ponding water deserve close review. A patch applied without understanding the membrane system may fail again.
Why source tracing matters
Water can travel across a low-slope membrane before entering the building. The repair scope should document the suspected entry point, surrounding condition, and any limits to the inspection.
- Review seams and laps
- Inspect penetrations and flashing
- Check drains and slope
- Document compatible repair materials
