Single Ply Membrane Roofing

Advanced Membrane Roofing Technology

Single ply membranes have become the modern standard for flat roofing across the United Kingdom. Used extensively in commercial construction and increasingly specified for domestic projects, single ply systems offer a proven combination of performance, longevity and value that traditional flat roofing materials struggle to match.

These membranes are factory-manufactured sheets produced under strict quality controls, ensuring consistent thickness and reliable performance across every installation. Depending on the system and the building, they can be mechanically fixed to the roof deck, fully adhered using specialist adhesives, or ballasted with gravel or paving slabs. This versatility makes single ply membranes suitable for virtually any flat or low-pitch roof, from small residential extensions to large-scale commercial developments.

TPO Membranes

Thermoplastic Polyolefin (TPO) membranes are one of the fastest-growing choices in the flat roofing market. TPO offers excellent UV resistance, making it particularly well-suited to exposed roof areas that receive prolonged sunlight. The white reflective surface of TPO helps to reduce solar heat gain, improving the energy efficiency of the building below and contributing to lower cooling costs during warmer months.

TPO seams are heat-welded using hot air, creating joints that are stronger than the membrane itself and ensuring a fully watertight finish across the entire roof area. TPO is also an environmentally friendly option – it is fully recyclable at the end of its service life, making it a responsible choice for clients who are mindful of sustainability.

PVC Membranes

Polyvinyl Chloride (PVC) single ply membranes have a proven track record spanning over 30 years in the roofing industry. PVC is a flexible yet strong material that delivers excellent fire resistance, making it a popular specification for commercial buildings, schools and healthcare facilities where fire safety is a key consideration.

Like TPO, PVC membranes are joined using hot-air welded seams, producing strong, reliable and fully waterproof connections. PVC is available in a wide range of colours and finishes, allowing architects and building owners to achieve the desired aesthetic while benefiting from outstanding weatherproofing performance.

EPDM Membranes

Ethylene Propylene Diene Monomer (EPDM) rubber membranes are renowned for their exceptional durability and longevity. EPDM is highly resistant to UV radiation and ozone exposure, which means the membrane maintains its flexibility and waterproofing properties for decades without degradation. Many EPDM installations have a potential lifespan of 50 years or more, making them one of the longest-lasting flat roofing solutions available.

EPDM membranes can be supplied in large single sheets, which minimises the number of joints required on the roof and reduces the risk of future leaks. This makes EPDM an excellent choice for straightforward flat roof areas where a clean, seamless finish is desired.

Key Benefits of Single Ply Systems

• Lightweight – Single ply membranes add minimal load to the roof structure, eliminating structural loading concerns and making them ideal for refurbishment projects as well as new builds.
• Superior seam strength – Hot-air and heat-welded seams create joints that are stronger than the membrane itself, delivering long-term watertight performance.
• Rapid installation – Large sheet sizes and efficient welding techniques mean faster installation times, reducing labour costs and minimising disruption to the building below.
• Manufacturer-backed warranties – Leading single ply systems come with comprehensive manufacturer warranties of up to 30 years, giving building owners long-term peace of mind.
• Excellent flexibility – Single ply membranes retain their flexibility in extreme temperatures, from freezing winters through to the hottest summer days, without cracking or splitting.
• Aesthetically clean finish – The smooth, uniform appearance of single ply membranes provides a neat, professional finish that enhances the look of any building.
• Versatile platform – Single ply roofs are suitable for green roof installations and solar panel mounting systems, supporting sustainable building design.

Applications

Single ply membrane roofing is suitable for a wide range of building types and project sizes. We regularly install single ply systems on commercial warehouses, distribution centres, schools, hospitals, retail units and office buildings. On the domestic side, single ply membranes are an excellent choice for residential extensions, new-build homes, garage roofs and refurbishment projects where a modern, high-performance flat roofing solution is required. Whether the project involves a new build or the replacement of an existing flat roof, our team has the expertise to deliver a professional installation that meets the highest standards.
