Why Choose the Right Flat Roof System
Flat roofs on extensions, garages and dormers need to be watertight, durable and correctly specified. We install systems that come with strong manufacturer-backed guarantees and are built to last. Whether you’re replacing a failed felt roof or building new, we recommend the best option for your project and budget across East London.
Systems We Install
- GRP (fibreglass) flat roofing — Seamless, reinforced laminate with typically 20+ year guarantees. Ideal for domestic extensions and garages; low maintenance and highly weather-resistant.
- EPDM rubber roofing — Single-ply rubber membrane, flexible and long-lasting. Suitable for larger areas and complex details; excellent for green roofs or where flexibility is needed.
- Torch-on felt — Multi-layer built-up felt systems for cost-effective flat roofing where GRP or EPDM isn’t specified. We use quality felts and correct lap and detail work.
- Warm and cold roof construction — We build to current building regs, with correct insulation and vapour control where required.
