Warm Roofs for Conservatories

Transform your conservatory into a comfortable, energy-efficient living space with a warm roof from Keystone Glazing. Our high-performance warm roofs help regulate temperature, reduce glare and improve insulation, so you can enjoy your conservatory all year round.

We are a local, family-run company with more than 25 years’ experience, replacing conservatory roofs across Chichester, Bognor Regis, Emsworth and West Sussex. In most cases we keep your existing frames and base, so a new roof costs far less than a new conservatory or extension.

A warm roof is an insulated, solid or tiled roof replacement designed for conservatories. Unlike traditional glass or polycarbonate roofs, which lose heat in winter and overheat in summer, a warm roof provides far better thermal efficiency, making your conservatory a usable, energy-efficient space throughout the year. Inside, you get a plastered ceiling that feels like part of the house, with room for lights and roof windows.

We fit the Supalite warm roof system, made to measure for your conservatory and available as pitched, tiled and flat roofs:

Solid warm roofs

A fully insulated, tiled roof, ideal for maximum energy efficiency and durability. It creates a seamless extension of your home and is available in a choice of tile finishes.

Hybrid warm roofs

Solid insulated panels combined with glazed sections, letting natural light in while keeping high thermal performance.

Lightweight tiled roofs

A cost-effective alternative to a traditional conservatory roof, offering a low-maintenance, attractive and energy-efficient upgrade.

Flat warm roofs

A crisp, modern finish for lean-to and orangery-style rooms, often paired with a roof lantern or rooflights to keep the room bright.

A solid roof doesn’t have to mean a dark room. We can add roof windows, rooflights or a lantern to your new warm roof so the space stays bright. See our rooflights, skylights and roof lanterns.

Most conservatories with sound frames and a solid base can take a warm roof. At the survey we check the frames, base and walls to make sure they can carry the new roof, and recommend any strengthening needed. If your frames or glass are past their best, we can replace them at the same time – see our conservatory installations and repairs.
