Solid Roof Extensions

Evolution 4 is the first roofing system designed to give you the flexibility to combine solid and glazed roofing seamlessly. It helps you extend your living space and enhance thermal performance to give you a room that you can use all year round.

Whether you are constructing a new home extension or replacing an old existing conservatory roof the Evolution 4 roof can give you total design flexibility and the ability to create stylish and thermally efficient rooms like no other solution on the market.

The Evolution 4 roofing system is constructed from insulated composite external panel and Kingspan slab insulation, which are strong and robust yet extremely thermally efficient.

The Structure of the roof utilises market leading Premium roof system to provide strength and rigidity – you can be sure it can withstand anything Mother Nature has to offer.

At Coral, we understand the importance of natural light in any home extension. The great feature of an Evolution 4 roof is that it can incorporate one, or a number of glazed panels that allows daylight to penetrate deep into your roof, making the space instantly brighter.

The glass panels can be inserted to replace any of the aluminium roofing panels, in any shape enabling you to maximise the light in your room or produce a very contemporary design not easily achievable with other types of roofing system.

Internally the Evolution 4 roof is stunning. It can deliver a magnificent vaulted ceiling and incorporates the Evolution 4 roof internal pelmet around the perimeter, where light can be installed. At the ridge and the top of the Evolution 4 roof you can insert or hang lights in a place where you otherwise wouldn’t be able to on a vaulted ceiling

If a vaulted ceiling isn’t for you then there is an option of a suspended ceiling, allowing you to continue the ceiling height from an adjoining room or to give your room a more ‘cosy’ feel.

Unrivalled Design.

The Evolution 4 roof can be formed into any shape or style. Glazing panels can be inserted anywhere to help you maximise the use of natural light and give you a truly bespoke design.



All Evolution 4 roof designs come complete with a perimeter ceiling system as standard, not only providing the perfect place for spotlights and speakers, but it gives the effect of lifting the vaulted ceiling, giving a light airy feel to the new room.

The Evolution 4 roofs can incorporate the Premium Cornice – hiding the guttering and giving your conservatory a modern, aesthetically pleasing feature.

Externally the Evolution 4 roof is finished in Anthracite Grey to complement any housing style and give a contemporary look.
The Evolution 4 roof is quick to install compared to other solid roofs on the market and because of its pre-fabricated design, doesn’t require any onsite cutting, reducing waste and disruption.
