Frequently Asked Questions - Conservatory - Warm Roof

What is a warm roof conservatory? 

A warm roof conservatory is a conservatory with a solid, insulated roof. The solid, insulated structure significantly reduces heat loss through the roof in comparison to fibreglass, polycarbonate and even energy rated glazing. Warm conservatory roofs are tiled with metal or plastic tiles, most often to match the tiles on the house.

Do you need planning permission for a warm roof conservatory?

The simple answer is usually no. Upgrading to a solid conservatory roof doesn’t usually require planning permission because it falls under permitted development, however, you should always check with your local council. You do, however, still need Building Regulations approval, and the Leka Roof is MFA certified, so it complies with building regulations by design).

Does a tiled roof make a conservatory warmer?

Tiled conservatory roofs offer better insulative qualities than common fibreglass, traditional build, glass, and polycarbonate roofing systems, helping trap warm air to keep the space warm for longer. The Leka roof is fully insulated with PIR sheets or EPS polystyrene with additional products that also enhance thermal efficiency further.

How to make a conservatory roof warmer? 

The best way to make a conservatory roof warmer is to replace it with a solid, insulated roof, significantly reducing heat loss. Other methods include insulated roof blinds and insulating window films; however, these methods are less effective and won’t provide a great deal of heat retention in the winter.

Does a glass roof make a conservatory warmer? 

Glass conservatory roofs are warmer than fibreglass and polycarbonate roofing systems, but they are not as warm as solid roofs like the Leka Roof. The main issue with glass roofs is their transparency. In summer, glass amplifies and traps heat like a greenhouse, and in the winter, glass offers no protection from glare or heat loss.

How to build a warm roof conservatory

If you want a tiled, insulated roof, you must specify a lightweight roofing system to ensure no remedial work is required to the conservatory base and frames in many cases. Your installation company should always check and ensure your windows/doors/glass is sufficient to take the weight of a new conservatory warm roof.

Standard, tiled roofs are too heavy for conservatories, so a lightweight system like the Leka Roof is essential. The Leka Roof replaces roofs made from glass or polycarbonate, and it can be installed as the original roof on new builds.

The Leka system is designed and built to order by independent approved Leka installers (please ask your installers to ensure they have been trained on the Leka System), ensuring we have ultimate control over the quality of hardware and system design.

The Leka roof is built in layers, starting with a GRP frame. Installers then fix internal Leka boards or standard plasterboards to the frame. Leka boards have long-lasting qualities, however, 12.5mm foiled backed plasterboard is also sufficient in achieving correct energy values.

Insulation sheets (PIR sheets or EPS polystyrene) are then installed, followed by load-bearing outer sheets made from high-grade plastic and XPS foam.

The last step is tiling the roof; the Leka Roof uses engineered tiles that mimic concrete or slate and are around half the weight of the natural alternative. Although these are physically different, they are very realistic and provide as close a match as possible to the real thing.
