Roofing Systems

The right system for the right roof.

Every system below has a place - and a set of limits. We specify for the roof, the substrate and the exposure, then explain the reasoning before work starts.

S/01

Liquid-applied waterproofing

A cold-applied resin, usually reinforced with fleece, that cures into one continuous waterproof layer following the exact shape of the roof.

Typical roof types: Small to mid-sized flat roofs, balconies, dormers, gutter linings and detail areas.

Request a roof assessment
Best applications
  • Detail-heavy roofs
  • Balconies and walkways
  • Refurbishment over sound substrates
  • Upstands, outlets and penetrations
Main strengths
  • Fully seamless - no laps or welds
  • Bonds to the substrate
  • Excellent around complex geometry
  • No hot works on most systems
Important limitations
  • Substrate must be sound, clean and dry
  • Application is weather- and temperature-dependent
  • Coverage and thickness must be controlled carefully
S/02

Single-ply membranes

Factory-made sheet membranes rolled out and hot-air welded or bonded into a continuous waterproof covering, usually over insulation laid to falls.

Typical roof types: Extensions, apartment blocks, commercial roofs, terrace decks.

Request a roof assessment
Best applications
  • Large uninterrupted roof areas
  • New builds and extensions
  • Commercial and multi-unit roofs
Main strengths
  • Fast to install over big areas
  • Consistent factory-made thickness
  • Welded seams are testable on site
  • Wide range of build-ups and fixings
Important limitations
  • Heavily detailed roofs need more hand-forming
  • Fixings and edge details must suit local wind exposure
  • Seam quality depends on workmanship and conditions
S/03

Reinforced bituminous membranes

Multi-layer bituminous sheets, torch- or self-adhesive-applied, building up a robust waterproof covering in two or more plies.

Typical roof types: Larger flat roofs, podium decks, commercial and mixed-use buildings.

Request a roof assessment
Best applications
  • Roofs needing extra robustness
  • Podiums and trafficked areas
  • Refurbishment of existing built-up roofs
Main strengths
  • Redundancy from multiple layers
  • Long-established, well-understood technology
  • Good puncture resistance
Important limitations
  • Heavier build-up than single-ply
  • Some systems involve hot works and require strict controls
  • More layers means longer installation on complex roofs
S/04

EPDM roofing

A synthetic rubber membrane, often installed as a single sheet across the whole roof field with bonded or mechanically fixed perimeters.

Typical roof types: Small to medium domestic flat roofs with simple shapes.

Request a roof assessment
Best applications
  • Simple rectangular roofs
  • Garages, outbuildings, garden rooms
  • Straightforward extensions
Main strengths
  • Few or no field seams
  • Flexible across temperature swings
  • Low maintenance in service
Important limitations
  • Detailing relies on bonded accessories rather than welds
  • Less suited to heavily penetrated roofs
  • Surface can be vulnerable to sharp mechanical damage
S/05

Zinc and architectural metal roofing

Standing-seam and panelised metal roofing where the roof is a visible architectural element as much as a weathering layer.

Typical roof types: Architectural residential projects, dormers, canopies, feature elevations.

Request a roof assessment
Best applications
  • Feature roofs
  • Premium new builds
  • Pitched-to-flat transitions
Main strengths
  • Distinctive architectural finish
  • Very durable when correctly detailed
  • Works on both pitched and low-pitch designs
Important limitations
  • Higher cost and longer lead times
  • Demands precise substrate and ventilation detailing
  • Coastal exposure requires careful material and fixing selection

Service life and guarantees vary by system, specification and installation conditions. We confirm any guarantee in writing for your specific project rather than quoting a blanket figure.
