Learn to love your extension again with a revitalising tiled roof

Innovation in building design has come on leaps and bounds over the last few decades, making no exception with glazed extension roofs. Gone are the days where the only option would be to grin and bear an inefficient glass roof that couldn’t be used in the hottest and coldest months of the year. Lightweight tiled roof technology via the Guardian Warm Roof enables homeowners right across Dorset to rejuvenate their glazed extensions; effectively creating a space that can be used all year round.

Quick and easy to install, as approved Guardian Warm Roof installers, our revolutionary tiled roofs for Weymouth & Dorset extensions are exceptionally watertight and acoustically sound. Tailored to your specific requirements we can even retrofit a new tiled roof to an existing extension structure, depending on its condition.
