Roof Carrier Membranes
Specialist roof carrier membranes provide long-lasting waterproofing for a wide range of roofing, including concrete, timber, metal decks, OSB, and Decotherm insulation. Designed for strength and flexibility, they form a seamless barrier against water ingress and are widely used in both flat and pitched applications. These membranes are a key component in many commercial and industrial roofing systems, where performance and reliability are critical. Whether used in new builds or refurbishments, they deliver consistent results across various substrates.

Specialist Roof Carrier Membranes
Roof carrier membranes provide dependable waterproofing for a wide range of roofing applications, including use over concrete, OSB, timber, metal decks, plywood, and Decotherm insulation. Designed for flexibility and long-term durability, they create a seamless protective layer that adapts to both flat and pitched roof designs. These membranes are ideal for use in cold-applied, warm roof, and green roof systems, and are a trusted solution for both new builds and refurbishment projects across commercial and industrial sectors.
For straightforward specification and installation, many systems are available as part of complete roofing kits. These kits include all essential components needed for new GRP roofing installations or refurbishment works, ensuring compatibility, reducing preparation time, and supporting consistent, high-quality results on site. With strong resistance to movement, temperature change, and water ingress, roof carrier membranes remain a core element in modern roofing systems that demand performance and reliability over time.
Roof Carrier Membranes FAQs
Can roof carrier membranes be used on both flat and pitched roofs?
Yes, roof carrier membranes are engineered for use on both flat and pitched roofs. Their flexible and robust structure allows for effective waterproofing across varied gradients. This makes them ideal for commercial and industrial settings, as well as certain residential applications where long-term performance is a priority. Always check compatibility with the specific slope and roof design before installation.
Are these membranes suitable for overlaying existing roofing systems?
Many roof carrier membranes are suitable for overlaying existing roofs, provided the substrate is structurally sound and correctly prepared. This is especially useful in refurbishment projects, as it reduces downtime and costs associated with full roof removal. It’s important to check product data sheets and obtain technical advice to confirm suitability before proceeding.
Do they require a primer before application?
Priming may be required depending on the substrate material and the specific membrane system used. Surfaces such as metal, timber, or concrete may need preparation to ensure proper adhesion. Always consult the manufacturer’s instructions and product guidance to determine if a primer is necessary and which type is compatible.
How do these membranes perform in extreme temperatures?
Roof carrier membranes are developed to perform well under a wide range of temperatures. High-quality options provide strong resistance to thermal movement and UV exposure. This makes them reliable in both very hot and very cold climates, where standard membranes may crack or degrade. Performance data is usually available in the product documentation.
Are they compatible with green roof systems?
Yes, many roof carrier membranes are compatible with green roof systems. They serve as a waterproof base layer, protecting structural elements beneath from moisture and root intrusion. When installing under soil, drainage, and vegetation layers, membranes must be root-resistant and installed with care to ensure continuous protection. Specific systems may require additional components for full compliance.
