Plygene Gutter Linings
Supply and installation of Plygene gutter linings — a premium, flexible waterproof membrane providing seamless, long-lasting protection for gutters on industrial, domestic and commercial buildings.
As approved contractors, Guaranteed Roofing Solutions Ltd supply and install Plygene systems manufactured by Sharmans to the full manufacturer specification, backed by guarantees of up to 25 years across Cambridge, Essex, Hertfordshire, Bedfordshire and East Anglia.
What is Plygene?
Plygene is a high-performance, flexible gutter lining system manufactured by Sharmans. It is designed to provide a seamless, fully-bonded waterproof membrane that lines the inside of existing gutters, eliminating the joints, seams and corrosion points that cause the majority of gutter leaks.
Unlike traditional gutter replacement, Plygene is installed directly over the existing gutter profile. The flexible membrane forms a continuous, joint-free lining that accommodates thermal movement and structural settlement without splitting or pulling away from the substrate.
This makes Plygene the ideal refurbishment solution for industrial, commercial and domestic buildings where replacing the gutter would be costly, disruptive, or impractical — extending the life of the existing gutter for decades at a fraction of the replacement cost.

How We Install Plygene Gutter Linings
Every installation follows the manufacturer's full system specification for guaranteed performance
Gutter Survey & Cleaning
The existing gutter is thoroughly inspected, cleaned out and any debris, vegetation or deteriorated coatings removed to expose a sound surface.
Substrate Preparation
Repairs are carried out to any damaged or corroded areas, and the surface is primed where required to ensure proper adhesion of the Plygene membrane.
Membrane Lining
The Plygene gutter lining is measured, cut and fully bonded into the gutter profile, forming a continuous, seamless waterproof layer.
Detailing & Outlets
All outlets, downpipe connections, upstands and junctions are carefully detailed and sealed to ensure watertight transitions.
Reinforcement
Additional reinforcement is applied at stress points, joints and changes of direction to provide long-term performance under movement.
Inspection & Sign-off
A full water test and inspection ensures the system meets specification, with guarantee documentation issued upon successful completion.
Ideal Applications
Plygene is suitable for virtually any gutter type on industrial, commercial and domestic buildings, and is especially effective where the existing gutter is leaking, corroded, or has failed at the joints but the main structure remains sound.
