Our Flat Roofing Systems

✅ Sarnafil Single Ply Membranes

We are experienced installers of Sarnafil Single Ply roofing systems, which offer:

Excellent waterproofing and UV resistance
Fast, flame-free installation
Ideal for warm and cold roof applications
Clean, modern finish.

Sarnafil is a globally trusted name in residential flat roofing and is known for its longevity and design flexibility.

✅ Liquid Plastic Roofing Systems

For complex or irregular roof shapes, liquid plastic systems provide a seamless, joint-free membrane that fully bonds to the surface. Benefits include:

Ideal for overlays and awkward details

BBA certified and manufacturer-backed warranties

We specify liquid-applied systems from leading manufacturers, ensuring the best quality finish every time. For example, Sika Liquid Roofing systems offer seamless, waterproof protection ideal for complex roof details and refurbishments.
Their cold-applied membranes reduce fire risk and ensure fast, safe installation on residential and commercial roofs.
Certified to meet BS6229 and leading industry standards, they provide long-term durability and weather resistance.
Sika solutions are perfect for garages, extensions, and warm or cold roof build-ups requiring fully vented substrates.

Flat Roof Construction Types

We can form flat roof substrates to suit your project requirements:

Warm Roof Construction

Rigid insulation placed above the structural deck
VCL (vapour control layer) to BS6229
Fully sealed and insulated system
No ventilation required

Cold Roof Construction

Insulation between joists below deck
Requires cross ventilation to prevent condensation
Often used in garages and porches

Ventilated Hybrid Systems
