Before installing EPDM rubber roofing, the roof deck must be:

• Clean – Free from dust, debris, grease, and loose materials
• Dry – No trapped moisture beneath the membrane
• Smooth & Even – No sharp edges, gaps, or uneven joints
• Secure – All boards firmly fixed with screws, no movement

A well-prepared surface ensures the EPDM membrane bonds correctly, prevents future lifting or bubbling, and maximises the lifespan of your flat roof.

We don’t rush installations — we prepare them properly. Because a roof is only as good as the surface beneath it.

The EPDM membrane is fully bonded to the prepared roof deck using specialist adhesive, creating a seamless, watertight, and wind-resistant system.

This method:

• Eliminates movement and lifting
• Prevents water ingress
• Withstands UK weather conditions
• Delivers long-term performance with minimal maintenance

In short: a fully adhered system locks the membrane in place, ensuring strength, stability, and longevity.

EPDM detailing is the process of carefully shaping, bonding, and sealing the membrane around edges and roof features to create a fully watertight finish.

It involves:

• Forming internal & external corners properly
• Using primer and seam tape for secure joins
• Installing edge trims correctly
• Ensuring all penetrations are sealed with precision

EPDM trims are fitted along roof edges to secure the membrane, protect the perimeter, and create a clean, professional finish.

The Core Principle

The membrane is bonded, then mechanically fixed and sealed with edge trims to prevent wind uplift and water ingress at the roof perimeter.

Why It Matters:

• Locks the membrane firmly in place
• Protects exposed roof edges
• Directs rainwater correctly
• Enhances durability and appearance

In short: Trims secure the weakest part of a flat roof — the edges — ensuring strength, stability, and long-term performance.
