Retorque/replace fasteners; clean laps. Local banding with PU/polyurea + geotextile or butyl bands. Full‑area: spray PU/Polyurea or TPO overlay with wind‑uplift design. Post‑cure water test and adhesion pulls.

Understand the stress points, treat them with right termination coatings and cover the deck with right waterproofing membrane that has a UV resistance and high puncture resistance

Summary
Industrial roofs (metal/PEB) leak chiefly at fasteners, sheet overlaps, skylight terminations, wall/roof junctions, and penetrations. Movement, vibration, and UV drive failures.
Symptoms
- Drips at fasteners during rains
- Wet streaks along side laps/end laps (capillary action)
- Leaks at skylight edges or around penetrations
Probable causes
- Aged/embrittled sealants and tapes
- Improperly torqued fasteners or degraded washers
- Poor skylight termination detailing; negative slope at laps
Solution paths
- Positive-side repairs on roof with high‑movement sealants and bands
- Local reinforcement with PU/polyurea banding at skylights and junctions
- Full‑area re‑waterproofing for aged roofs (spray PU/polyurea or TPO overlay where suitable)
Recommended technologies
- Polyurea or spray PU (trafficable, fast cure) over primed metal
- TPO overlay (mechanically fixed) where system is compatible and wind‑uplift design is done
- High‑movement silicone/PU hybrid sealants; butyl tapes at laps
Quick SOP
1) Inspect and retorque/replace fasteners & washers; clean and abrade laps.
2) Apply primer; band side/end laps and penetrations with liquid membrane + geotextile or butyl bands.
3) For full‑area: spray PU/polyurea to spec DFT with UV topcoat; or install TPO per wind‑uplift design.
QA / acceptance
- Water test after cure; adhesion pull-off on representative areas; fastener torque log
