Manufacturers are keeping on top of roofing trends with products to suit all projects, from glass roof glazing to a Building Award-winning innovation


Glass roof glazing

A listed building at 184 Shepherds Bush Road has been converted from a motor garage and service depot with showroom into a modern office building. To reduce solar glare, Schollglas’ opaque and tempered safety glass GEWE®-dur-H, which features a completely silkscreened surface, was chosen. The outer surface was glued to an insulating panel, and a powder-coated sheet metal was used to seal the internal face of the panel. GEWE-therm® multi-insulating glass panels with a neutral solar control coating and modern safety properties were chosen for the transparent areas. Schollglas

Rainwater solution for cascading roofs

Marley Alutec has supplied a rainwater solution for the cascading roofs of Leicester’s Centre for Medicine. The building posed a rainwater drainage challenge, and a complex calculations and bespoke components had to be made to cope with the cascading run-off. The roof drainage design specification had to meet Category 3 standard, which dictates that rainwater systems must have capacity for high levels of rainfall. Marley Alutec products were chosen as they are lightweight yet offer the durability required.

Natural roofing slate
A private art gallery in Betws Y Coed in Conwy, Wales, has been roofed using Cupa R4 natural Spanish slates from Cupa Pizarras. The product was chosen as the gallery required a slate that was sustainable and would be a suitable fit to the existing environment. The 50cm x 25cm slates were used and secured to the tiling battens with copper nails.

Natural slates
Cembrit’s Alpina natural slates have been used for the redevelopment of an award-winning holiday park in north Devon.

The company used the hook fixing method to secure the slates and lock them together tightly to achieve a neat finish.

Tiled roofing system

Equinox tiled roofing system from Eurocell was specified for a 1990s-built two-bedroom cottage in Shropshire. According to the company this 12.5m x 6.5m roof is thought to be the largest ever Equinox tiled roof to be erected in the UK. The roof forms a distinctive P-shape using five hips and a valley. The Equinox system has a 5 to 350 pitch variable ring beam assembly that increases the types of roofs that can be replaced while adjustable angles on the hip, valley and ridge add up to easier fitting, and ensure that tiles and ridges sit correctly for finishing.
