Conservatories

Conservatory roofs

Too hot, too cold, too loud in the rain? Change the roof and you change the room. Glass, polycarbonate or a solid tiled roof, fitted to your existing frames.

Garden rooms

Keep the conservatory, lose the problems

The roof is responsible for most of what people dislike about an older conservatory: the glare, the heat in summer, the chill in winter, the drumming when it rains. If the frames and base are sound, replacing the roof alone can make the room useful every day of the year, for far less than starting again.

We survey the existing structure first. If the frames are tired as well, we can replace those at the same time so that everything matches and carries one guarantee.

Solid tiled roofs

Supalite lightweight tiled roofs with an insulated, plastered ceiling.

Solar-control glass

Reflects summer heat, keeps winter warmth and stays cleaner for longer.

Polycarbonate

25mm or 35mm multiwall sheets: the economical way to renew a roof.

Quieter in the rain

Glass and tiled roofs are dramatically quieter than old polycarbonate.

Bright conservatory interior with a pitched glazed roof

A solid roof: the biggest change

A Supalite roof replaces the old glazing with a lightweight aluminium frame, rigid insulation, a waterproof membrane and slate-effect or tile-effect tiles. Inside, the ceiling is insulated, boarded and plastered, usually vaulted to keep the height, and ready for downlights.

The room stops behaving like a greenhouse and starts behaving like an extension. Roof windows can be set into the slope where you want daylight. Changing from a translucent to a solid roof normally needs Building Regulations approval, and we take care of the application.

  • Lightweight aluminium structure designed for conservatory frames
  • Insulated, plastered vaulted ceiling
  • Choice of tile colours
  • Optional roof windows and downlights

Glass or polycarbonate

If you love the sky overhead, a modern glass roof keeps it. Solar-control units reflect much of the sun's heat and cut glare, a low-emissivity coating holds warmth in winter, and an easy-clean outer surface uses rain to wash away dirt.

Polycarbonate remains the most affordable option. Today's 25mm and 35mm multiwall sheets insulate far better than the thin panels fitted twenty years ago, and tinted finishes take the edge off bright sun.

Questions

Good things to ask

Straight answers to the questions we hear most about this product.

Can my existing frames take a solid roof?

In most cases, yes. Supalite roofs are engineered to be light enough for conservatory frames in good condition. We check the frames, the base and any reinforcement at survey and tell you honestly if anything needs strengthening or replacing.

Will a solid roof make the room dark?

It will be less bright than a glass roof, but the side windows still bring in plenty of light. One or two roof windows restore daylight to the centre of the room and to the room behind.

Do I need Building Regulations approval to change the roof?

Replacing glass or polycarbonate like for like does not normally need approval. Changing to a solid roof generally does, because the structure is no longer a conservatory for the purposes of the regulations. We arrange this for you.
