NO Aluminium, NO Condensation Risks

If you have a traditional glazed or polycarbonate roofing system on your conservatory, you probably find that there are two major problems with it.

  1. It's too hot in the summer and too cold in the winter.
  2. The glare in the winter and summer unbearable.

The Leka System solves both these issues with proper insulation set into a solid, tiled conservatory roof. This creates a more usable space year-round.

Why Choose A Leka Conservatory Roof Conversion?

  • Truly lightweight

    A truly lightweight tiled conservatory roofing system (no smoke screens). We do not brand the new LEKA System as a lightweight roofing system without having the facts to back it up, whilst other products/materials actually weigh nearly double that of a traditional glass conservatory roof.

  • No outer plywood needed

    Removing the usual need for an outer plywood material which again is open to deterioration over a period of time and replacing with the new LEKA structural, 100% weatherproof, lightweight and insulated boarding system reduces the overall weight of the roofing system and improves the overall U values of the finished product.

  • Better lifespan

    Using either a Metrotile OR Britmet lightweight sheet for your outer finish of your new sunroom or a Tapco OR Lite Slate alternative you can rest assured that the product provides a better lifespan to a heavy alternative tile and is lighter than that of concrete or traditional slate.


  • More innovation less complexity

    With innovative products throughout and combining insulated sheets with PIR or EPS insulation the LEKA system has less elements to install onsite which speeds up your installation timings with average installation only taking 2-3 days including removal of your old conservatory roof.

  • Glass reinforced plastic

    Using GRP or glass reinforced plastic allows a structurally tested, lighter alternative to aluminium and timber when providing the main structural roof rafters. GRP is not at risk of sweating /condensation or cold bridging like aluminium. Nor is GRP open to wood worm, moisture absorption or potential rotting such as timber. The Leka System Structural profiles are manufactured and comply with BS EN13706.

  • Leka insulated board

    With our own Leka insulated finishing board replacing the need for plasterboard as the internal finish prior to plastering, this new innovative board is a third the weight of a plasterboard and insulated at the same time.

    For a more traditional cost-effective finish, standard 12.5mm plasterboards or our unique ECOTECH boards can also be utilised as part of the Leka ECO range which (in most cases) doesn't affect our exceptional U values.

  • Weighing within 10-12% of a traditional glass roof

    Average Leka system roofs weigh within 10-12% of a traditional glass conservatory roof which allows (in most cases) your existing conservatory frames to take the weight of your new Leka roofing system.

  • Improved energy efficiency

    Having a load bearing structural insulated and weatherproof outer sheet allows the use of less roofing bars and so our roof bars can be spaced further apart which reduces weight and also improves energy efficiency levels.

Mr and Mrs Williams


"After careful consideration and reviewing a number of solid roof products on the market…..we are so glad we chose the Leka System.

We now actually use the conservatory more than the house and the workmanship of the installation company was second to none."

Mr and Mrs Beccles


“The new roof has completely changed how we use our conservatory. Instead of being too hot in summer and too cold in winter we are now able to use it all year round. Along with our new bifold doors it has meant we have been able to sit and enjoy our garden far more this summer than ever before. Thank you so much!”

Mr David Burles and Heidi Sachs

This was too much of an opportunity to pass by... we are amazed by the innovation of product layers running throughout this system. The testing and energy assessments, along with simplicity and lifespan of the system really impressed us."

Mr Morgan


"Already loads warmer in the conservatory and can’t wait to move furniture back in. Will provide us with what we wanted, turning a 6 months use a year conservatory, into a year round garden room! Thank You"

Brandon Cook

Director of Windoormate UPVC

"The new Leka Roofing system is leading the way through innovative design and construction. We are extremely impressed with how the structure is far more thermally efficient and lighter than alternatives we have seen over the years.

With no Aluminium or Timber elements, we can see how the system can provide better future proofing and a longer lifespan for conservatory customers across the UK"
