Solid Conservatory Roofs


Leka Tiled Roof Conservatory Systems

Window Warehouse supplies tiled conservatory roof systems to installers along the South coast for new conservatory build and refurbishment projects. There are two systems to choose from, Leka tiled conservatory roofs for traditional pitched-roof conservatories and the Leka flat roof system for creating orangery roofs with a roof lantern.

Leka Tiled Conservatory Roof

Leka Tiled Conservatory Roof

The lightweight solid roof conservatory roof system that uses GRP ringbeam and rafters for a strong, solid conservatory roof that can be installed typically in 2-3 days.

Perfect for conservatory refurbishments or new glazed extensions.

Leka Orangery Roof

Leka Orangery Roof

The flat Leka roof system designed to create bright, light-filled orangeries. It uses the same technology as Leka’s pitched roof solution, incorporating a roof lantern.

A great choice for modern orangery-style extensions.
