Shop nowChoose your membrane
Two FlexiProof membrane constructions, selected around the substrate, roof geometry and level of reinforcement your project needs.
A smooth, homogeneous membrane for clean, prepared roof decks. It creates a simple, elegant waterproof layer with fewer field joins when ordered to the roof dimensions.
EPDM laminated to a reinforcing fleece for added toughness and a more forgiving bond over suitable prepared substrates. It is a considered choice where reinforcement or substrate tolerance matters.

Cut to size
Calculated by membrane area from the selected stocked width and the length your roof requires.
Full rolls
Available separately in stocked widths and arranged in size order so the right roll is easy to find.
Measure once. Order confidently.
The most useful enquiry includes the maximum deck width and length, edge and upstand allowances, penetrations, drainage positions and a few clear photos.
Record the maximum finished width and length—never work from an assumed nominal size.
Note upstands, parapets, rooflights, pipes, corners and every drainage point.
Tell us the substrate and whether the roof is new work, an overlay or a refurbishment.
Confirm membrane, adhesive, flashing, trims, outlets and tools before the order leaves.

SprayGrade is a two-component spray-applied liquid rubber system engineered for large commercial and industrial roofing projects. If your project involves any of the following, SprayGrade is likely the better system:
Projects of 300m²+ where brush/roller application is impractical and speed is essential.
Warehouses, logistics units, factories, retail parks and industrial roofs.
High-output spray application reduces project timelines dramatically vs traditional methods.
Forms a continuous 2mm+ membrane with zero joints — no weak points across the entire roof.
Large roofs completed in days, not weeks. Minimal disruption to building occupants and operations.
Backed by a 15-year warranty as a complete supply-and-install system from Forti Nova.
Direct Answer — EPDM vs Liquid Rubber vs SprayGrade
EPDM is a flat roof membrane system — best for residential, garden rooms and extensions up to ~300m². Liquid Rubber HBS200 is a brush or roller-applied repair and detailing system — ideal for small areas, complex details and refurbishment. SprayGrade is a spray-applied commercial system — the right choice for large flat roofs on warehouses, factories and commercial buildings where output and seamless coverage are the priority.
