Stop Box Gutter Leaks Once and for All
Box gutters are one of the most common sources of water ingress in commercial and industrial buildings. When the original lead, felt, or zinc lining deteriorates, water can track back into the building causing widespread and costly damage to insulation, steelwork, stored goods, and interior finishes.
JPM Site Services permanently resolves box gutter failures using single-ply membrane lining systems or full metal box gutter replacements, depending on the condition and requirements of each gutter. These solutions are installed directly over the existing gutter, eliminating the need for costly and disruptive removal.
Our Lining Systems
Single-Ply Membrane
EPDM and TPO single-ply systems offer flexibility, excellent UV resistance, and are ideal for larger gutters and complex detailing.
Full Metal Replacement
Where gutters are beyond repair, we supply and install full metal box gutter replacements — fabricated to size and finished to last.
Gutter Repairs
Where the gutter structure is sound, targeted repair and coating systems can extend the life of the existing lining at lower cost.
Survey & Diagnosis
We inspect gutters with CCTV where necessary to identify the precise location and cause of failure before specifying a solution.
Why Single-Ply Membrane?
- Seamless — no joints or laps that can fail over time
- Applied over existing linings — no stripping required
- Fully bonded — will not lift or delaminate
- Cold-applied — no hot works, no naked flames
- Available in any colour — including matching to existing roof
- long-term workmanship guarantee as standard
The JPM Process
All works begin with a thorough survey of the gutter, including structure, falls, and outlet condition. We prepare a detailed specification and quotation before any works begin. Once on site, our team work cleanly and efficiently to minimise disruption — most gutter lining projects are completed within 1–3 days. A full photographic report is issued on completion.
