Seamless flat-roof waterproofing
Liquid Rubber Roofing
Liquid rubber creates a continuous waterproof membrane without traditional sheet laps. It can be a practical option for suitable flat roofs with complex shapes, rooflights, pipes and difficult junctions.

Is it right for your roof?
Where this service can make sense.
Every flat roof needs to be assessed on its own condition, construction and details. These are common situations where this service may be considered.
- Roofs with awkward shapes or details
- Areas around rooflights and penetrations
- Suitable existing flat roofs needing renewal
- Seamless waterproofing requirements
- Extensions and smaller roof areas
- Complex junctions and upstands
The working process
From first inspection to finished roof.
The exact method depends on the existing roof, but the work follows a clear sequence focused on preparation and waterproof detailing.
- 01
Assess the existing roof
The surface and underlying roof are checked to confirm whether a liquid-applied system is appropriate.
- 02
Clean and prepare
Loose material, contamination and vulnerable areas are dealt with so the membrane can bond correctly.
- 03
Reinforce key details
Edges, joints, outlets and penetrations receive the preparation and reinforcement their shape requires.
- 04
Apply the membrane
The waterproof coating is applied evenly to create a continuous finished surface.

Details matter
A flat roof is only as reliable as its vulnerable points.

This existing project photograph shows liquid rubber used as a focused valley repair. Repair work is assessed separately from a complete liquid-rubber roof, and the available guarantee depends on the condition and scope of each repair.
