MFA Approved – Solid Conservatory Roof

We designed the lightweight Leka Roof to outperform as well as outlast common glass and polycarbonate roofing systems. It’s so good it has been approved by MFA, the approved building inspector licenced by the Government, and our patented technologies lead the way for innovation in the industry. Superb home improvement

The Leka Systems tiled warm roof conservatory is protected by GB patent no. 2538540 and is one of the most innovative roof systems in the marketplace today’.

The MFA approved Leka System is a truly lightweight, tiled, solid conservatory roof system with an industry leading U value available from an astonishing 0.10.

Lightweight and Energy Efficient

We do not brand the new LEKA System as a lightweight energy efficient roof system, without having the facts to back it up, whilst more traditional products/materials actually weigh nearly double that of a traditional glass conservatory roof and have lower U values.

Do not just take our word for it, compare the facts?

Improved Insulation & Reduced Glare

If you have a glazed or polycarbonate roofing system on your conservatory, you may find the space too hot in the summer and too cold in the winter. The reason for this is poor roof insulation. It is also common for homeowners to find glare in the winter and summer unbearable. The Leka, roofing tiles system solves both these issues with proper insulation set into a solid, tiled conservatory roof. This creates a more usable space year-round than your existing conservatory roof.

Leka Orangery Roof Breakdown

Below you will find a detailed system break down of the Leka Orangery Roof. This provides lighter and better, Orangery roof insulation. We will explain how the only roof system of its kind in the world can transform your existing Orangery or enhance your proposed new Orangery project.

Step 1 – GRP Rafters

First, ‘Glass Reinforced Plastic’ rafters are added to your existing, Orangery window frames, including a GRP structural ring beam, rafters and ridge. GRP is not prone to:

  • wood worm
  • moisture absorption such as traditional timber
  • condensation
  • thermal bridging such as bulky Aluminium alternatives.

The beginning of your improved Orangery roof insulation.

Step 2 – Thermal Insulation

Insulated PIR sheets or EPS are snugly fitted with a 15mm gap from the internal Leka sheets. Variable roof U value options are available, helping provide high-value thermal efficiency and BBA certified products in some cases aimed at delivering a significant benefit in achieving a better Orangery, roof insulation efficiency level.

Step 3 – Outer Sheets

Next, strong, load-bearing and insulated outer sheets are added. These ensure less roofing bars and higher efficiency.

Our Leka outer boards have been engineered to offer:

  1. A structural alternative to plywood
  2. A significantly lighter alternative to any other roof covering board
  3. A 100% waterproof outer covering
  4. A thermally efficient board

Step 4 – Outer Weatherproof Coating

An outer weatherproof coating is then applied by your installation company.

This will provide final waterproofing along with a stylish finish, ensuring that your Orangery roof is the ultimate in watertight insulation.

Step 5 – Glass Lantern

A glass lantern is then lowered onto the current structure and fixed into place by your installer.

The glass lantern will allow light to flood through into the Orangery and provide an elegant looking finish.

Step 6 – Fascias and Guttering

UPVC fascias and cappit are now attached onto the edges of the structure.

This then allows guttering to also be attached onto the UPVC fascias cappit as an optional step.


Step 7 – Internal Leka Boards

Next, internal Leka sheets are added underneath the GRP rafters. The Leka sheets are 100% waterproof and one third the weight of plasterboard.

These sheets have unique thermal qualities as well, but allow for a traditional plaster skim finish to provide a nice visual aspect ready for painting afterwards. For a more traditional cost effective finish, standard 12.5mm plasterboards can also be utilised as part of the Leka ECO range which (in most cases) doesn’t affect our exceptional U values.

Step 8 – Internal Plaster

The underside of the roof then has a high quality, traditional skim plaster finish applied.

Low energy spotlights can then also be fitted for the best possible interior lighting.
