Modern Roofing have experience in rubber roofing (mostly in repairing of these epdm roofs) but, would not recommend a roofing system with so many inherent problems as the best solution for your flat roof. There has been many documented rubber roofing problems with shrinkage, leaking flashings, failing seams and adhesives. This is compounded by the fact that most if not all warranties do not cover flashings, seams, ponding water or even workmanship. Modern Roofing believe the combination of glued seams and shrinking membrane has resulted in the many seam failures at around 5 to 7 years.
Rubber epdm roofing also has very serious issues with unprofessional contractors claiming to be rubber roofing experts. Most rubber roofs are installed and repaired by roofers that have no special knowledge or training. They take on epdm roofing jobs because they are seemingly easy to install, inexpensive, require no special expensive equipment and rubber roofing membranes will be sold to anyone with no license or approval required.
For the above reasons rubber/epdm roofs are very rarely installed on any commercial roof in the uk
Modern Roofing would recommend PVC Single-ply membrane as the best product for flat roofing projects in the UK. With Modern Roofing operating in both the domestic and commercial markets we purchase a huge quantity of PVC membrane annually, therefore can negotiate a large discount that allow us to give cheaper commercial rates to our domestic customers. Our commercial discount allows us to offer a premium product at rates that can compete with the rubber roofing companies.
