SupaLite conservatory roofs offer an effective way to improve the thermal performance of an existing conservatory. By combining a lightweight roof system with high-performance insulation, they can help reduce heat loss in winter and make the room more comfortable when temperatures rise in summer.
For homeowners looking to replace an outdated polycarbonate or glass roof, this can mean a more usable space throughout the year without replacing the entire conservatory. But what makes the SupaLite system different, and how does it compare with the roof you already have?

What is a SupaLite conservatory roof?
A SupaLite roof is a lightweight conservatory roof system designed to replace an existing glass or polycarbonate conservatory roof. The system uses a lightweight aluminium frame, insulation and a breathable membrane, with lightweight tiles providing the external finish.
The SupaLite system is designed for different types of conservatory shapes and can be tailored to suit the existing structure. There are also colour options and design options available, helping you create a tiled conservatory roof that complements the rest of your home.
Natural light doesn’t have to be sacrificed when choosing a solid roof. Glazed areas can be incorporated into the design, while options such as roof lanterns can help maintain a bright and open feel.
Why thermal efficiency matters
Thermal efficiency is one of the main reasons homeowners consider a replacement conservatory roof. Older roofs can allow significant heat loss during colder months, while traditional glass and polycarbonate can also contribute to uncomfortable temperatures when the sun is strong.
A SupaLite tiled conservatory roof uses multiple layers of insulation to help regulate the temperature inside your conservatory. Its warm roof construction is designed to reduce heat loss, helping the room stay warmer in winter and more comfortable during warmer weather.
Better insulation can also mean less reliance on heating, potentially helping to reduce heating costs and energy bills. While the exact performance will depend on the specification and existing structure, upgrading an older roof can make the space more practical to use throughout the year.
SupaLite versus a traditional polycarbonate roof
Older polycarbonate conservatory roofs can struggle with heat loss, temperature fluctuations and excessive noise. A SupaLite roof offers a more thermally efficient alternative, with a solid construction designed to improve comfort throughout the year.
| Feature | SupaLite tiled roof | Traditional polycarbonate roof |
| Thermal efficiency | Better insulation helps reduce heat loss and temperature fluctuations | More limited thermal performance can contribute to heat loss and uncomfortable temperatures |
| Comfort | Designed to help create a more comfortable room throughout the year | Can become very hot in summer and cold in winter |
| Noise | Solid construction can help reduce noise from heavy rain | Can be noticeably noisy during heavy rain |
| Natural light | Glazed panels can be incorporated into the roof design | Naturally allows plenty of light through the roof panels |
| Appearance | Tiled finish offers a more substantial, modern look | Traditional polycarbonate panels can look dated as they age |
| Usable space | Helps make the conservatory more practical as year-round living space | Extreme temperatures can make the room less comfortable to use |
Building regulations and planning permission
Replacing a conservatory roof isn’t simply a case of removing the old roof and putting a new one in its place. The existing conservatory structure needs to be assessed to make sure it is suitable for the proposed roof system.
Building regulations are an important part of the process, particularly when replacing a translucent roof with a solid conservatory roof. The structural performance, insulation and ventilation of the completed roof all need to be considered.
The SupaLite system has been independently assessed and approved for relevant applications, helping provide reassurance that the system can meet the required Building Regulations standards when correctly specified and installed. At Renaissance Conservatories, we can advise on the requirements for your particular project and help ensure the replacement roof is correctly specified and installed.
Planning permission is not normally required for a conservatory roof replacement, although this can depend on the property and the proposed work. Restrictions can also apply to certain properties and designated areas, so it is worth checking before work begins.

How is a SupaLite roof installed?
Choosing Renaissance Conservatories means having an experienced team manage your replacement roof from the initial assessment through to completion. Here’s what you can expect from the installation process.
-
Assessing the existing conservatory
The first step is to inspect the existing conservatory roof, frames and structure. This helps establish whether the existing conservatory is suitable for the new roof system and whether any structural work is required.
-
Removing the existing roof
Once the specification has been agreed, the existing conservatory roof is carefully removed. This could involve taking out old polycarbonate panels or traditional glass before preparing the structure for the replacement roof.
-
Installing the SupaLite system
The lightweight aluminium frame and insulated roof components are installed to the required specification. The breathable membrane and insulation form part of the roof construction before the external finish is completed.
-
Adding the roof tiles and glazing
Lightweight tiles are fitted to provide the finished appearance, with available tile colours and glazing options selected to suit the property. Where required, glazed panels can help bring natural light into the room.
-
Completing the project
The final installation is checked and the relevant building regulations requirements are addressed, leaving you with a new conservatory roof designed to improve the comfort and performance of the space.
