Description
When a standard rubber membrane simply isn't enough, this fleece reinforced EPDM delivers a step-change in flat roof performance. The factory-bonded polyester fleece backing transforms the membrane into a robust, dimensionally stable sheet that is 40% more puncture resistant and delivers 180% greater tear strength compared to comparable non-reinforced EPDM membranes — making it the go-to choice for professional roofers and demanding DIY applications alike.
At a finished thickness of 2.54mm yet weighing under 2 kg/m², this membrane is easy to handle on the roof while providing outstanding protection against the full force of the UK climate — UV radiation, freeze-thaw cycling, ponding water, and temperature swings from -40°C to +120°C. No flames, no torching, no complicated equipment.
Suitable for new build, refurbishment, and direct overlay onto existing felt or asphalt substrates, this 18.58m² roll covers a typical garage, extension, or garden room roof in a single efficient installation.
Why Fleece Reinforced — Not Standard EPDM?
Standard EPDM membranes rely solely on the rubber layer for all their strength. The fleece reinforced version adds a factory-laminated polyester fibre backing that fundamentally changes the performance profile:

Frequently Asked Questions
EPDM rubber roofing membranes, kits and accessories - straight answers from the Rubber Roof UK team.
What size is the fleece reinforced EPDM roll?
Each roll measures 1.525m wide x 12.19m long, giving 18.58m² of coverage - enough for a typical garage, extension or garden room roof in a single efficient installation.
What makes fleece reinforced EPDM different from standard EPDM?
A factory-laminated polyester fleece backing is bonded to the rubber, giving 40% greater puncture resistance and 180% greater tear strength than non-reinforced EPDM, plus better dimensional stability and more uniform adhesive bonding.
Can this membrane be installed over an existing roof?
Yes, it's suitable for direct overlay onto existing felt, asphalt or bituminous surfaces as well as new build, which can eliminate the cost and mess of stripping off the old roof covering.
How thick is the finished membrane and how much does it weigh?
The total sheet thickness is 2.54mm (EPDM plus fleece backing combined), and it installs at under 2kg per m², so it's manageable to handle on the roof despite its added strength.
What is the expected service life?
This membrane has a 50+ year expected service life when correctly installed and maintained, requiring no recoating or resealing - just periodic visual inspection and debris clearance.
Does it need heat or flame to install?
No, it's a fully adhered, cold-applied system with no flame, torching or specialist gas equipment required, making it safe and achievable for professional contractors and competent DIYers.
What temperature range can it withstand?
The membrane remains fully flexible from -40°C to +120°C, handling UK frosts, summer heat and freeze-thaw cycling without cracking or deforming.
What accessories do I need to complete the installation?
You'll need compatible EPDM bonding adhesive, primer, seam tape and detailing accessories. The substrate must be clean, dry and structurally sound before application - please order all required accessories to complete your system.
What substrates can this membrane be bonded to?
It adheres directly to timber, OSB, plywood, concrete, and existing felt, asphalt or bituminous surfaces.
Is professional installation required?
Competent DIY installers can fit this membrane with correct preparation and accessories, though for complex roof geometries, multiple penetrations, or commercial applications, professional installation is recommended.
How is the membrane seamed for larger roofs?
Joins are made using compatible splice tape or seam adhesive to create fully watertight seams, and the fleece backing means 34% fewer seams are needed compared to modified bitumen systems.
What projects is this membrane best suited to?
It's ideal for flat roof extensions, garden rooms and offices, garages and workshops, commercial flat roofs, dormer and mansard roofs, porches and canopies, outbuildings and sheds, and overlay refurbishment projects.
