Learn more about Pro Green Roof Membranes

It’s no surprise to see the continued popularity of green roofs for commercial buildings. They deliver a range of benefits spanning environmental to cost saving, helping businesses to become greener in every sense and deliver on CSR promises. This includes improving energy efficiency and reducing consumption, supporting wildlife and creating recreational spaces for people to enjoy in urban areas.


Permagard is proud to supply a comprehensive range of long lasting, robust green roof drainage membranes for larger domestic and commercial green roof projects. We are committed to providing the highest quality drainage membranes when and where you need them, alongside the technical information and support to make your design a success.  


The drainage layer is a key component of any green roof system. With Permagard’s recycled HDPE Green Roof Membranes, you can trust that the drainage element of your system will meet your needs and for years to come.  


Our professional green roof membrane membranes support effective water management in your green roof system, allowing excess water from heavy rain to safely drain away without causing waterlogging. This protects the vegetation from damage and avoids excess loading on the structure. 


Each PermaSEAL drainage and storage membrane features a cavity designed to retain sufficient water to sustain your chosen vegetation. We offer membranes with different sized cavities that we can tailor to your project specification, taking into account your objectives, the deck construction, proposed build up and plant life. 


Our range can accommodate intensive and extensive systems, specific vegetation from sedum to larger shrubs and trees, as well as driveable and walkable requirements. From simple extensive membranes with in-built geo-textile layers (PermaSEAL 8) to 60mm drainage and water-retention membranes with high compression strength ideal for intensive green roofs or decks (PermaSEAL 60P), we have the membrane you need. 

Professional green roof membranes to match your needs

Getting the correct design and specification of drainage layer is essential for the success of your green roof system. If you’re unsure what drainage layer you need, then our team is more than happy to feed into the specification for the proposed drainage options. Whether you require an extensive or intensive green roof, walkable or drivable paving or a simple gravel-filled deck finish, we stock the appropriate drainage membrane. 

With fantastic stock availability, we’re able to offer the following membranes:
