Warm Roof Systems
A well-designed warm roof system transforms a conservatory or extension into a comfortable, usable space throughout the year.
At Broadview Windows, we install advanced warm roof systems from Leka Systems, providing homeowners across Hertfordshire with a practical solution to improve insulation, appearance and overall performance.
Traditional glass or polycarbonate conservatory roofs can struggle to regulate temperature. A warm roof system replaces that structure with a fully insulated, lightweight roofing solution designed to deliver significantly improved thermal efficiency.
What is a warm roof system?
A warm roof is a solid, insulated roofing system engineered to minimise heat loss while maintaining a lightweight structure.
Leka Systems insulated roofs are manufactured using advanced composite materials. They are designed to outperform older roofing methods in both insulation and durability, while remaining suitable for a wide range of conservatory and extension types.
The result is a space that feels like a natural extension of your home rather than a separate seasonal room.
Improved thermal performance
The primary benefit of a tiled conservatory roof is improved insulation. By incorporating high performance insulation within the roof structure, heat is retained during colder months and reduced during warmer periods. This helps to maintain a more consistent internal temperature throughout the year.
Many homeowners find that these thermally efficient roof systems allows their conservatory to be used comfortably in winter as well as summer, making it a practical living area rather than an occasional space.
Lightweight and structurally efficient
Leka warm roof systems are specifically designed to be lightweight. This often means that in many cases, the existing conservatory frames can remain in place, reducing the need for extensive structural alterations.
The system is engineered for strength while remaining significantly lighter than traditional solid roof alternatives. This combination of durability and reduced weight makes it a practical and efficient solution.
Designed for longevity
Warm roof systems from Leka are manufactured to exacting standards and come with long term component warranties. Designed to outperform and outlast regular glass and polycarbonate alternative systems, they provide reassurance that your investment will continue to perform reliably for many years.
A natural appearance
These roofing systems can be finished with external tiles designed to complement your existing property. Internally, plastered ceilings and integrated lighting options can be incorporated to create a seamless finish. The result is a room that feels fully integrated into your home, rather than an add on structure.
