EPDM / Single-Ply Membrane Roof Coating
No matter what style of roof you have the process is similar.
EPDM and other single-ply membranes are known for their durability and flexibility, making them a common choice for flat and low-slope roofs on both residential and commercial buildings. Their single, continuous sheet design offers excellent resistance to weathering when properly installed and maintained.
Even the best rubber or synthetic membranes eventually show their age, though. Over time EPDM roofs can shrink, lose seam adhesion, or develop the surface chalking that signals the material is starting to dry out. Once a single-ply membrane begins to fail, water can find its way in quickly, so it’s important to address early warning signs before they turn into costly leaks and internal damage.
Our EPDM / Single-Ply Roof Coating Process
Roof Inspection
We examine seams, flashings, penetrations, and the overall membrane condition across the full roof, paying particular attention to areas of shrinkage or tension where seams are most likely to fail. This inspection guides exactly where extra reinforcement will be needed once we begin coating.
Cleaning and Preparation
The membrane is cleaned to remove chalking residue, dirt, and any biological growth such as moss or algae. Chalking in particular needs to be fully removed, as this powdery residue is one of the main reasons coatings fail to bond properly to ageing EPDM surfaces.
Repairs
Lifted seams, punctures, and tears are re-secured or patched using methods suited to single-ply membranes, restoring the integrity of the roof before coating begins. This ensures the finished coating is protecting a structurally sound surface rather than bridging active leak points.
Priming
A compatible primer is applied across the prepared surface to maximise adhesion, which is especially important on rubber-based membranes that can otherwise resist bonding with liquid coatings.
Membrane Coating Application
The liquid membrane coating is applied in a seamless, even layer over the entire roof, with extra build-up at seams, penetrations, and edges where stress and movement are concentrated. This creates a single, monolithic waterproof surface with no exposed joints left to fail.
Signs Your EPDM / Single-Ply Roof Needs Attention
- Shrinkage causing tension and pulling at seams or edges
- Seam tape or adhesive lifting or peeling away
- Powdery, chalky residue across the membrane surface
- Small punctures or tears from foot traffic or debris
- Discolouration or fading patches appearing across the roof
