A flat roof system is at the height of fashion and will attract so much outside attention. Integrate skylights or lanterns for a fabulous finishing touch.
A fine example of contemporary design

Flat roofs have unequalled elegance and will add strength and simplicity to your space. If you combine the product with bi-folding doors or large sliding doors, it will draw even more light inside to make it feel deceivingly spacious. At your request, we can also design in an asymmetrical finish with an overhang should you want an undercover seating area in your garden or patio.

The flat roof extension has clever insulation technology so that it always offers fantastic energy efficiency – therefore, you can rely on it being a comfortable space in any weather.

Customised for you

Your roof will be unique and as individual as you are. Premier Windows will make it an exact match for your home, shaping and finishing it accordingly. How about also having some bi-folding doors? Without the need for additional pillars, we can integrate bi-folds that span up to 5.8m.
