Roof styles.

The Classic conservatory shape. Together with attractive roof windows the Edwardian Guardian Roof is the traditional option for styling and convenience, maximising the room space below.
Lean-to.
The Guardian Lean-To is ideal to maximise space at the rear of the house. The ends can either have one or two hips (slopes). Ideal for kitchen extensions, the roof can go as low as 15o with roof windows.
Victorian.
The Victorian roof is also ideal if you may not have much available space in your garden.
The internal plaster finish on the roof has an attractive appearance with its facet front finish.
Combination.
A P-shape simply combines the benefits of two different styles to maximise your living environment. A T-shape combination is available, as well as bespoke solutions to make your conservatory as individual as you are.
Gable Ended.
The gable ended main feature is the continuous height it brings to the room due to its long central ridge.
The gable end allows you to get the most from your roof windows providing a light and airy space.
