Commercial Gutter Lining Systems - London & South East
Specialist Gutter Lining Systems for Commercial & Industrial Properties
At DL Jones Roofing Services, we specialise in protecting and extending the life of commercial and industrial guttering using advanced lining systems – delivering a cost-effective, long-lasting alternative to full gutter replacement across London and the South East.
Operating from South Croydon since 1987, our teams work daily across London, Surrey, Kent, Sussex, and Essex, lining gutters on industrial sites, commercial properties, schools, and local authority buildings.
Failing gutters are one of the most common – and most underestimated – causes of water ingress and building fabric damage on large commercial and industrial roofs. Our advanced lining systems adapt to a wide range of gutter profiles, increase capacity where needed, and deliver exceptional durability against corrosion, ponding water, thermal movement, and harsh weather.
The result is a high-performance, watertight system installed with minimal disruption – at a fraction of the cost and programme time of full gutter replacement.
PolyRoof XtraFlex - Premium Seamless Gutter Protection
As part of our service, we install the PolyRoof XtraFlex system – widely regarded as one of the most advanced gutter lining technologies available today.
Cold-applied liquid system that cures to form a seamless, fully bonded lining
No joints or weak points, ensuring unrivalled watertight integrity
Highly flexible, coping with thermal movement and complex gutter details
Resistant to UV rays, ponding water, and weather extremes
Extends the service life of existing gutters by decades
The PolyRoof XtraFlex system is a cold-applied liquid lining that cures in place to form a seamless, fully bonded membrane inside the existing gutter – with no joints, laps, or weak points where water can penetrate. Because it is cold-applied, there are no hot works involved, making it safe to install on occupied buildings including schools, hospitals, and residential blocks where fire risk and disruption must be eliminated.
As approved Polyroof installers, we deliver the XtraFlex gutter lining system to the manufacturer’s specification, qualifying every installation for the full system guarantee. The same cold-applied liquid technology underpins our wider flat roofing and roof repair work – meaning a gutter lining project can be combined seamlessly with any associated roof refurbishment as a single coordinated programme.

Frequently Asked Questions
What is a gutter lining system, and how does it work?
A gutter lining system restores watertight performance to existing gutters by installing a new, durable waterproof membrane directly inside them – without removing or replacing the original gutter. The most advanced systems, such as PolyRoof XtraFlex, use a cold-applied liquid that is applied inside the cleaned and prepared gutter and cures in place to form a seamless, fully bonded membrane that conforms to the gutter profile and all its details.
Because the lining is seamless, it has no joints, laps, or seams – eliminating the weak points where traditional gutters fail. The cold-applied installation involves no hot works, making it safe for occupied buildings. The result is effectively a brand-new watertight gutter surface inside the existing structure, restoring full performance at a fraction of the cost of full replacement. For buildings where gutter problems are part of a wider roof issue, our roof surveys and reports service can assess the complete picture.
How long do gutter lining systems last?
A correctly installed premium gutter lining system extends the serviceable life of the existing gutters by 20 to 30 years. Our premium installations carry a 30-year guarantee covering materials, manufacture, and installation – backed by both the manufacturer and DL Jones as the approved installer.
Is gutter lining more cost-effective than replacement?
Yes – significantly. Full gutter replacement on a commercial or industrial building is expensive and disruptive: it typically requires removal of the existing gutters, significant access equipment or scaffolding, associated roof works where the gutter meets the roof covering, and a longer programme during which the building is exposed. Gutter lining avoids almost all of this – the existing gutter stays in place and a new watertight membrane is installed inside it.
The cost saving is typically substantial, and the programme is far shorter with minimal disruption to building operations. For property management companies and local authorities managing tight maintenance budgets across multiple buildings, gutter lining frequently allows a failing gutter to be restored for a fraction of the replacement cost – freeing budget for other priorities.
