About Wandsworth

Wandsworth is one of the busiest areas for property management in South London, with a high concentration of buy-to-let investors and managing agents. Many of our projects here are on behalf of portfolio landlords who need consistent quality, fast turnarounds between tenancies, and proper invoicing.

What we offer in Wandsworth

EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber membrane that's become the gold standard for flat roofs across the UK. A single sheet, fully adhered or mechanically fixed, with no seams in the field of the roof.

What is EPDM?

A synthetic rubber membrane manufactured in large sheets (up to 15m wide and 30m+ long). Most residential installations are done in a single sheet — no field seams at all.

The rubber is highly flexible (-40°C to 150°C operating range), UV-stable, and chemically inert. It doesn't pollute rainwater runoff, which is increasingly important for sustainable drainage.

Why we recommend EPDM

• 50+ year lifespan — outlasts felt and GRP by decades
• Seamless single sheet — no joins to fail in the field
• Flexible — handles building movement without cracking
• Recyclable — sustainable end-of-life option
• Quick install — most residential roofs done in 1-2 days
• Cost-effective long-term — though higher upfront than felt, lower lifetime cost

Where EPDM works

• House extensions and dormers
• Garage roofs
• Porches and bay windows
• Garden offices and outbuildings
• Most residential flat roofs with adequate falls (minimum 1:80)

Where EPDM isn't ideal

• Walkable surfaces (use GRP instead)
• Roofs with heavy foot traffic
• Roofs that need to be very low pitch (under 1:80 fall)
• Bitumen/asphalt surfaces (EPDM degrades on contact — we use a separation layer)
