Professional Flat Roof Installation in London
Modern flat roof installation built for durability, drainage, and long-term weather protection.
A flat roof is only as good as the engineering beneath the surface. In London, the biggest enemy of a flat roof isn’t just the rain—it’s ponding water. If the “fall” of the roof isn’t calculated perfectly, water sits, stagnates, and eventually penetrates the membrane.
At Jade Roofing Experts, we specialize in high-performance flat roof installation across London. We don’t just lay a membrane; we ensure your roof deck is structurally sound, properly insulated to Building Regulations Part L, and designed to shed water efficiently for 30+ years.
💧 Tired of “Patch and Hope” Repairs? Upgrade to a seamless GRP or EPDM system and never worry about a leaking flat roof again.
Flat Roof Installation Specialists You Can Trust
Flat roofs require precision installation — poor workmanship is the number one cause of leaks and early failure.
Our experienced roofers install flat roofing systems that comply with UK building regulations and manufacturer specifications, ensuring maximum lifespan and peace of mind.
We work on:
- Home extensions
- Garages & outbuildings
- Balconies & terraces
- Commercial flat roofs
Modern Flat Roofing Systems We Specialize In
GRP Fibreglass (The Seamless Shell)
Best for balconies and high-traffic areas. GRP is a cold-applied liquid resin that cures into a single, seamless sheet.
EPDM Rubber (The Flexible Specialist)
Best for residential extensions. This high-density synthetic rubber expands and contracts with the London weather, meaning it never cracks or blisters.
Reinforced Bitumen (High-Performance Felt)
Best for garages and cost-conscious projects. Forget the old "mineral felt" of the past; we use modern, polyester-reinforced torch-on systems.
The "Warm Roof" Upgrade: Save on Energy Bills
If you are installing a new flat roof over a living space (like a kitchen extension), we highly recommend a Warm Roof System.
- How it works:We install high-performance rigid insulation above the roof deck.
- The Benefit:It eliminates condensation and keeps your room significantly warmer in winter, meeting the latest UK energy efficiency standards.
