Standing seam roofing has become an established style over the last decade. First seen on large retail units the system is now often seen on smaller, centrally located new builds. Often specified because of the its contemporary design possibilities, unlike a traditional pitched roof each sheet is fixed to the buildings structure in one length omitting the laps between sheets that are usually found upon composite or twinskin roofs.

Curved roofs constructed using the standing seam method are fixed in the same way as built up systems. An internal liner is fixed in place first, followed by bars and support brackets. The design of the laps allows the fixings to be hidden, combined with a non ferrous material for the top sheet this form of roof is often considered leak and corrosion proof. Sheeting is rolled from the coil on site in single continuous lengths from a container that is craned to roof level.

One project for Rolls-Royce saw the use of 120m long sheets, an example of some of the longest sheets to be used in the UK. The void is insulated before the weather or top sheet is fixed above. The top sheet is often aluminium lending the roof a metallic & modern appearance but may also be specified in steel which can be prove to be a cost effective option in many cases.
