About West Barnes

West Barnes is a small residential area between New Malden and Worcester Park. Edwardian and 1930s housing with traditional pitched roofs. Common work: re-tiling and chimney repairs.

What we offer in West Barnes

Flat and low-pitched roofs need different systems to pitched tile or slate roofs. The right choice depends on budget, foot traffic, exposure, and how long you plan to stay in the property.

Our flat roof systems

We install three main systems, each with real strengths. We'll always recommend what's right for your specific situation.

EPDM Rubber Roofing

Single-ply synthetic rubber membrane, fully adhered or mechanically fixed. No seams in the field of the roof. 50+ year lifespan.

• Lifespan: 50+ years (manufacturer warranties 20-25 years standard)
• Cost: £75-£95 per m² installed
• Pros: Seamless, very flexible, low maintenance, won't crack or blister

GRP Fibreglass Roofing

Cold-applied liquid resin and mat that cures to a hard, seamless, walkable surface. The premium choice for balconies and terraces.

• Best for: Walkable surfaces (balconies, terraces), complex shapes, premium installations
• Lifespan: 25-30+ years (25-year manufacturer warranties available)
• Cost: £85-£110 per m² installed
• Pros: Hard-wearing, fully bonded, can be any colour, slip-resistant options

High-Performance Felt

Modern torch-on felt is a different animal to old-school felt. Three-layer systems with 20+ year lifespan at the lowest price point.

How to choose

• Want the longest lifespan, lowest maintenance? EPDM
• Need a walkable surface (balcony/terrace)? GRP
• Budget is the priority? Felt
• Not sure? We'll look and recommend what's actually right for your situation.

Common flat roof problems

• Ponding water — flat roofs need adequate falls to drainage
• Blistering or splitting — usually poor installation or aged felt
• Leaks at upstands — where the membrane meets walls
• Edge deterioration — failed trims or edge details
• Age failure — felt over 15 years old becomes brittle

Building Regulations for flat roofs

Since 2022, flat roofs require insulation upgrades to meet current Part L Building Regulations when more than 25% is replaced. We install modern warm-roof construction with rigid insulation above the deck — keeps your home warmer and reduces energy bills.
