The Leka conservatory warm roof conversion delivers a smooth installation from start to finish, whether on an old conservatory or a new build.
We can fit it in 2/3 days with low waste and little downtime. It is made from GRP (glass-reinforced plastic) with a 40-year warranty on Leka components. It is the clear choice for a top-quality solid roof, but what’s the installation process?
This article covers everything you need to know.
Let’s jump in!
Specifying and designing the roof
The customer is visited on-site, and the conservatory structure is assessed to determine if the existing support is sufficient to bear the additional weight of the Leka roof. After this consultation, a quote is provided to the customer. If an order is secured, a site survey needs to be undertaken to obtain final measurements.
The Leka roof is highly configurable, so during your survey, we can discuss changing your roof’s pitch, shape, and profile. For example, if you have a lean-to conservatory roof, we can look at installing a gable Leka solid roof.
Manufacturing the roof
The full specification of the roof is then provided to our certified fabricator, who will manufacture the Leka roof in its entirety. First, the roof is digitally drawn in CAD software to create a detailed schematic. The roof is then made, sent to the shop floor to be measured and cut and finally packaged up for shipping.
We deliver the roof
The new warm roof is usually delivered on the same day the de-installation of the old roof begins, ensuring seamless, efficient installation.
The roof comes ready for assembly, and all Leka installers are trained to build up the system on-site to our high-quality standards. The old roof will be discarded in a skip on site and taken away for recycling so the materials can be reused where possible—converting a conservatory roof with the Leka system results in minimal waste.
Most existing conservatories can support the Leka roof because the Leka roof is a lightweight system by design. It can weigh less than many glazed roofs, so it doesn’t usually require any additional building work.
Building the new roof
Before roof installation, a new support structure may be needed to bear the additional weight of the new roof. The extent of this depends on the build. If not required, installation begins with the structural ring beam, manufactured from GRP, to provide a rigid connection between the roof and the structure.
Once the structural ring beam is in place, the roof rafters are installed with the ridge, building the ‘skeleton’ of the roof as per the specification. These are also manufactured from GRP, so they are lightweight and robust. The roof’s structure won’t warp, shrink, rot or degrade over time because it is made from GRP.
The next stage is to install the internal Leka boards. These are 100% waterproof and serve as the base for insulation, and they are drilled to the rafters.
With the internal boards in place, the insulation comes next. The Celotex sheets are snugly fitted with a 15mm gap from the internal sheets to create a warm air barrier and make the roof highly energy efficient. The sheets are perfectly installed between each rafter point to trap warm air in the 15mm gap.
The next step is the installation of the outer sheets. These are insulated and reinforced to reduce the number of roof bars needed. They are installed on top of the Celotex insulation and secured to the rafters.
The last stage is tiling the roof. Depending on the property and the required cosmetic look, we specify Tapco slate or Metrotile concrete tiles, which are cost-effective and deliver the desired performance.
Sign-off and quality control
After installation, we will inspect the installation for quality and call back on the roof two to three months after construction to assess the build.
Our commitment to you is simple – your Leka roof will last decades and transform the look and feel of your conservatory for the better.
