Why Replace It When You Can Upgrade It?

Traditional flat roof replacement means tear-off, scaffolding, skips, noise, and weeks of disruption, with a quote to match. WetSuit Roofing takes a completely different approach: we use your existing felt, EPDM, GRP, or bitumen roof as the base and spray a seamless, patented waterproof membrane directly over it. No rip out. No landfill. Typically 60% less cost than a full replacement, and backed by a 20-year manufacturer's warranty.

~60% Cheaper
Around 60% cheaper than a full rip-out and replacement, without compromising on quality.
Faster Installation
Much faster installation with less downtime. Most projects completed in 1–2 days.
Eco-Friendly
Far less waste going to landfill. Water-based, no VOCs, and no need for a skip.
No Weather Risk
No need to expose the building to the elements. Your property stays protected throughout.

WetSuit vs Other Roofing Systems

Why WetSuit® outlasts traditional flat roof systems (felt, EPDM, GRP and liquid membranes), and what every Surrey homeowner should know before paying for a full replacement.

Bitumen felt rolls being torch-applied to a flat roof Traditional ~10 years

Asphalt / Bituminous Felt

A 3-layer system of thin bitumen felts torched together with hot liquid bitumen.

  • Hessian fibres are prone to rotting, drying out and cracking with age or UV damage
  • Trapped moisture rising from below causes surface bubbles
  • Heavy 3-layer build can exceed what older decks can carry, leading to movement and cracking
  • Open-flame torch on installation (fire risk)
WetSuit® spray-applied membrane on a flat roof WetSuit® 20-Year Warranty

WetSuit® Spray Membrane

Self-adhering, single-coat membrane spray-applied straight over your existing felt.

  • Self-adheres with no laps or joints
  • UV stable for up to 15 years exposed
  • Doubles as roofing, deck or podium membrane, including green-roof applications
  • Compliant with the standard for resistance to water penetration
Bituminous coating being roller-applied to a flat roof Traditional Short shelf life

Bituminous Coating

Brush- or roller-applied bitumen used as a budget waterproofing layer.

  • Bonding properties reduce with age. Short shelf life.
  • Unsuitable for prolonged sun exposure. Dries out and goes brittle
  • Cracking lets moisture in from above
  • Needs polymer modification for any meaningful performance
WetSuit® 1 Part product mark WetSuit® All-substrate

WetSuit® 1 Part System

A single-component, self-levelling membrane that bonds to almost any flat surface.

  • Self-levelling. Ideal for standing-seam metal, aged SPF, wood and concrete
  • Spray, brush or roll-applied, up to 80 mm thick on a vertical surface
  • Can be fully reinforced with fabric for high-stress areas
  • Cold-applied. No torch, no naked flame.
Aged EPDM rubber roof on a commercial building Traditional Shrinks ~6%/yr

EPDM Rubber Roof

Single sheet of synthetic rubber rolled out and glued to the deck.

  • Sheet may shrink by as much as 6% per year
  • Edges pulled inward, seams open up and vent pipes get displaced
  • Seams sealed with water-soluble glue that fails over time
  • Goes brittle with temperature swings; wind can lift the sheet off the substrate
WetSuit® membrane stretched across a ruler showing extreme elongation WetSuit® 360% elongation

WetSuit® Elastomeric Membrane

A seamless rubber-like membrane that moves with the building instead of pulling apart from it.

  • Elongates to 360% of finished size with full recovery
  • Withstands extreme uplift pressure
  • Meets the standard for cyclic movement over joints over time
  • Bonds straight over your existing EPDM. No rip-out.
Polyurethane liquid membrane finish on a flat roof Traditional Moisture-sensitive

Polyurethane Liquid Membrane / GRP

Solvent-based liquid systems painted onto the substrate to form a waterproof skin.

  • Highly sensitive to substrate moisture. Vulnerable to peeling and de-bonding.
  • Water-filled blisters can form under the membrane, causing interior leaks
  • Blisters can grow large enough to need full membrane replacement
  • Strict moisture testing of the deck required before install. Easy to get wrong.
WetSuit® being sprayed onto a flat roof under controlled conditions WetSuit® 20+ year life

WetSuit® Liquid Membrane

Patented spray-applied membrane installed under strict QC to prevent the failures that plague other liquid systems.

  • Strict QC. Moisture content read before, during and after install.
  • Proven durability in all weather conditions
  • Suitable for waterproofing and damp-proofing of wet areas in buildings
  • Membrane will exceed a 20-year life expectancy

Surrey residential property with flat roof extension

Flat Or Felt, Residential Or Commercial. WetSuit Bonds To All Of It.

If your roof is structurally sound but tired, leaking, or approaching the end of its life, WetSuit is almost always the smartest upgrade available. It bonds directly over the substrate you already have:

Felt roofs. Ageing bitumen felt with leaks, blisters, or failing joints.
EPDM, TPO & PVC single-ply. Bonds seamlessly without tearing off.
GRP fibreglass, metal, concrete, timber, asphalt. All verified substrates.
Extensions, garages, and outbuildings with flat or low-pitch roofs
Commercial, industrial, and retail roofs where shutdown costs real money
Any roof across Surrey where a full rip-out would be disruptive or risky

Frequently Asked Questions

Everything you need to know before booking your free assessment.

WetSuit is typically around 60% cheaper than a full roof replacement. The exact saving depends on the size and condition of your roof, but most Surrey homeowners find it represents outstanding value, especially when you factor in the 20-year warranty and the cost of disruption avoided.

Most residential projects are completed in a single day. Larger commercial roofs may take 2–3 days. There is no need for scaffolding in most cases, and your property remains fully accessible throughout.

WetSuit bonds to virtually any flat roof substrate, including bitumen felt, EPDM, GRP fibreglass, single-ply membranes, metal, and concrete. The free assessment will confirm suitability for your specific roof.

The warranty is issued by the product manufacturer, not just by us as the installer. This means it is backed by the company that makes the WetSuit system, giving you an additional layer of protection beyond our own workmanship guarantee.

No. The WetSuit system is water-based and zero VOC, so there are no harmful fumes. You can remain in your property throughout the installation. There is also no need for a skip or significant disruption to your garden or driveway.
