Single Ply Membrane Roofing Installation

Factory-made membrane sheets, hot-air welded into a genuinely fused system, the standard choice for larger commercial flat roofs.

Single-ply membrane roofing uses large, factory-manufactured sheets, PVC, TPO or EPDM, installed mechanically fixed, fully adhered, or ballasted depending on the roof and wind loading. PVC and TPO seams are hot-air welded, genuinely fusing the sheets together rather than just bonding them with adhesive, which gives a stronger, more reliable joint. Brands like Sika Sarnafil, Bauder, Firestone and Renolit are widely specified across the UK.
