Built for the Trade by Warmer Roof

When your customer wants a modern flat roof that performs as well as it looks, you need a system that installs quickly, passes Building Regulations without hassle and delivers long-term reliability.

The Flat Roof System for Conservatories and Extensions does exactly that.

Designed specifically for conservatories and extensions, it gives you structural strength, outstanding thermal performance and a premium finish — all supplied as a complete, tested kit with a fast turnaround.

A Flat Roof System That Works as Hard as You Do

Exceptional Thermal Performance

Your customers expect year-round comfort. The Warmer Beam system keeps rooms cool in summer and warm in winter thanks to:

  • Premium honeycomb insulation
  • Insulated plasterboard (PIR)
  • Thermally efficient structural design

You deliver a room that feels like a true extension of the home — not a seasonal space.

Structural Strength Without the Weight

Our structural I-Beams are manufactured from C24 timber with a 10mm particle board web. They’re incredibly strong, and because they’re lighter than traditional timber trusses or steel, they place less load on existing frames and supporting walls — ideal for retrofit projects.

Suitable for Retrofit

The lightweight design means you can retrofit the Warmer Beam system onto existing conservatory frames with confidence, opening up valuable upgrade opportunities for your customers.

Make the Room Brighter with an Aluminium Roof Lantern

A flat roof doesn’t have to mean a dark room. Add a roof lantern and completely transform the space.

Our slimline S1 Aluminium Roof Lantern floods the room with natural light, creating a bright, airy living area your customer will love.

With ultra-slim 50mm sightlines and low-line aesthetics, it delivers more sky and less roof. From the outside, discreet rafter top cappings and a slim ridge provide a clean, modern appearance — far removed from bulky traditional T-bar systems.

Whether installed in a kitchen extension, open-plan living space or refurbished conservatory, the lantern:

  • Maximises daylight
  • Enhances the feeling of space
  • Creates stunning views by day and night
  • Adds architectural value to the property

It’s not just a light source — it’s a selling point.

Thermally Efficient. Secure. Built to Last.

The S1 lantern features innovative Thermlock® multi-chamber technology, helping you meet thermal requirements while maintaining slim aluminium styling.

Security is built in from the ground up:

  • Anti-tamper screws
  • Enclosed anti-tamper glazing
  • Security tape
  • Patent-pending glass lock
  • High-security ridge end

Your customers get peace of mind. You get a premium product you can confidently recommend.

Durable EPDM Protection with 50-Year Life Expectancy

Every flat roof is finished with a high-performance EPDM rubber membrane. We use the globally trusted Firestone RubberCover system for:

  • Exceptional durability
  • Minimal maintenance
  • Simple application
  • Long service life

With a life expectancy of up to 50 years, you’re installing a roof built for the long term — not a short-term fix.
