Orangeries incorporate a flat roof area, so designers require specialist knowledge of timber and load bearing capabilities. This is one of the reasons why many orangeries are constructed in oak, not only is it an immensely strong timber that can cover wide spans, but it creates a lavish interior when naturally oiled.
The partially flat roof of orangeries surrounding the roof lantern, means that it will be viewed from the upper windows of a property, so it is important that it has an attractive finish. Traditionally, the choice was to use lead, zinc or copper, which while mellowing to a beautiful patina added substantially to the final cost. So we recommend selecting a synthetic weatherproof material with a long guarantee.
