Rooflock PU Roof Coating

Advanced Polyurethane Waterproofing System for Commercial and Industrial Roofs

Rooflock PU roof coating is a high-performance polyurethane waterproofing system designed for flat roofs, metal roofs and industrial gutters. The seamless, elastomeric membrane provides long-term protection against standing water, UV degradation and weather exposure, making it ideal for complex roof layouts and refurbishment projects.

Total Cladding & Roofing Ltd is approved to install Rooflock PU, offering full surveys, specifications and manufacturer-backed installation across the UK.

What Is Rooflock PU Roof Coating?

Rooflock PU is a solvent-free, liquid-applied polyurethane membrane engineered to create a fully bonded, durable waterproof layer.
Unlike sheet systems, Rooflock PU forms a seamless, joint-free surface that eliminates traditional failure points such as welds, laps and seams.

Core characteristics include:

• High elasticity and tensile strength

• Excellent resistance to ponding water

• Strong adhesion to a wide range of substrates

• UV and weather stability

• Ability to accommodate complex detailing

This makes Rooflock PU suitable for both refurbishment and overlay applications.

Where Rooflock PU Is Commonly Used

Rooflock PU is typically installed on:

• Flat roofs with ageing membranes (felt, asphalt, PVC, EPDM)

• Roofs with poor drainage or standing water

• Industrial gutters and waterproofing channels

• Metal roofs requiring additional waterproof protection

• Roofs with many penetrations, joints or complex detailing

Its flexible formulation allows it to handle movement and temperature variation.

Benefits of the Rooflock PU System

Rooflock PU delivers several key advantages:

• Seamless waterproofing with no joints or welds

• Excellent performance under standing water

• Highly flexible and resistant to cracking

• Suitable for both flat and metal roof applications

• Low-odour, solvent-free formulation

• Faster installation compared to many alternatives

• Long-term manufacturer-backed warranties

• Minimal disruption to building operations

Suitable Roof Substrates

Rooflock PU can be applied to:

• Felt and bituminous membranes

• Asphalt roofing

• Single-ply systems (PVC, TPO, EPDM)

• Metal roof surfaces

• Concrete and screeded roofs

• Industrial gutters and drainage sections

A roof survey determines primer requirements and preparation steps.

System Longevity

Rooflock PU roof coating typically achieves 12–25+ years of service life depending on:

• System thickness

• Level of reinforcement

• Substrate condition

• Environmental exposure

The system is available in 12-, 15-, 20- and 25-year specifications.

Leak Prevention and Waterproofing Performance

Rooflock PU prevents leaks by:

• Creating a continuous, impermeable membrane

• Sealing penetrations, joints and laps

• Protecting vulnerable edges and details

• Resisting water ingress even under long-term ponding

This makes it ideal for problematic flat roofs.

Installation Process

Survey: Full inspection of the existing roof, moisture, adhesion and detailing.
Preparation: Cleaning, repairs, reinforcement and priming where required.
Application: Liquid-applied membrane installed to the specified film thickness.
Completion: Final inspection, quality assurance and warranty issue.

FAQs

Can Rooflock PU handle standing water?
Yes. It is designed to perform under permanent ponding conditions.
