FAQ
Flat Roof Questions Answered
How much does a flat roof cost in London?
Flat roof costs in London typically range from £70–£130 per m² installed, depending on the material and system chosen. EPDM rubber costs around £80–£110/m², GRP fiberglass £90–£130/m², and torch-on felt from £70–£100/m². London labour rates tend to be toward the higher end of national ranges. Contact us for a free, detailed quote for your specific property.
How long does a flat roof last in London?
A professionally installed flat roof can last 20–50 years depending on the material. EPDM rubber roofs typically last 40–50 years, GRP fiberglass 25–30 years, and quality felt systems 15–25 years. Regular professional maintenance can significantly extend the lifespan of any flat roof.
What is the best flat roof material for a London property?
For London’s wet, variable climate, EPDM rubber is the most durable and lowest-maintenance system. GRP fiberglass is ideal where a clean, seamless aesthetic matters (e.g. home extensions). Torch-on felt offers a cost-effective solution for garages and larger roofs. We always survey the property and recommend the best option for your needs and budget.
Do I need planning permission for a flat roof repair in London?
Most flat roof repairs and like-for-like replacements do not require planning permission in London. However, if your property is listed or in a conservation area, or if you are substantially altering the roof structure or height, you may need planning consent. We advise all clients on this before work begins.
How do I know if my flat roof needs repairing or replacing?
Key signs include: visible leaks or water stains on ceilings, blistering or cracking of the roof surface, pooling water that doesn’t drain, damaged or missing flashings, or a roof that is over 20 years old. We provide free surveys to assess the condition of your flat roof and recommend the most cost-effective solution.
Do you offer emergency flat roof repair in London?
Yes. We provide a rapid-response flat roof repair service across London for urgent leaks, storm damage, and waterproofing failures. Call 07572 455 326 for prompt assistance.
