What Is Membrane Roofing?
Membrane roofing is a continuous waterproof layer designed for roofs that are flat or have a very low pitch. Unlike metal roofing, which needs slope to shed water, a membrane creates a fully sealed surface that keeps water out even where it sits or drains slowly. It is the right system for flat roofs that would leak with conventional materials.
Where Membrane Roofing Works Best
Commercial and flat roofs
Warehouses, offices, retail, and apartment buildings with large flat or near-flat roof areas.
Modern and architectural homes
Contemporary homes with flat roof sections, parapets, and low-slope designs.
Decks and balconies
Waterproof membrane over trafficable decks and balconies above living spaces.
Low-pitch extensions
Single-storey and lean-to extensions where a flat or low-slope roof is the only option.
Our Membrane Roofing Process
We assess the roof structure and drainage, prepare the surface, and install a fully bonded waterproof membrane with proper detailing at every edge, upstand, and penetration. The detail work is where membrane roofs succeed or fail, and it is the part we get right.
