Contemporary in style, our flat roofs are a minimalist’s dream. We can add lanterns or skylights to drive light into your space.
Modern styling at its best

Permaframe’s flat roof is simple and minimalistic. It can be easily customised with skylights and lanterns and we can even install an overhang if you wish to have a covered area in your outdoor space.

Our flat roofs perform exceptionally well when it comes to energy efficiency, which will help control your heating bills. You’ll also be able to comfortably enjoy the space throughout every season.

Made to measure

All our roofs are made to your exact requirements. We will design the roof to complement your current structure. We can even add bi-folding doors that span up to 5.8m without requiring additional pillars.

A touch of light

We can showcase you many ideas to customise your flat roof, including a range of soffit and fascia options, lanterns and skylights. Your roof is totally unique and can be personalised to your style and performance needs.

Beautifully Pitched

For our lanterns, the design has been perfected. Our designers have worked hard to maximise the amount of natural light that will make its way through them, to create an airy and light-filled space. Our lanterns have thermal efficient components to ensure your space can be used all year long.

Frameless Skylights

For magnificent edge-to-edge glazing, there’s truly nothing like our modern frameless skylights. Fortunately for Permaframe customers, each skylight comes with noise reducing glazing as standard and is fitted with slim aluminium surrounds, a fully insulated housing section that benefits from Warm Frame technology.
