EPDM roofing (ethylene propylene diene monomer) is one of the most durable and low-maintenance flat-roof systems available in the UK. While it usually costs more upfront than felt, its long lifespan and reduced upkeep can make it the better long-term investment.
How Much Does EPDM Roofing Cost in 2025?
Most UK homeowners can expect to pay around:
- £80 to £120 per m² including materials and professional installation
- £1,500 to £3,500+ for a typical small domestic flat roof (around 20–30 m²)
Prices vary depending on roof size, access, insulation requirements, and your region (with London and the South East generally higher).
If you’re quoted £60–£70 per m², double-check what's included. That may be a basic system or exclude essential elements like waste removal or insulation upgrades.

While the m² price can be similar at the lower end, felt often needs replacing much sooner. Spread the cost over the roof's lifespan and EPDM generally works out cheaper per year, especially when maintained well.
Key Advantages of EPDM
- Long lifespan often 25–30+ years
- Low maintenance and very few seams for water to penetrate
- Highly weather-resistant and UV-stable
- Eco-friendly option compared with some alternatives
Questions to Ask Your Roofer
Before you go ahead, ask:
- Which membrane thickness and brand are being installed?
- Does the quote include removal of the existing roof and waste disposal?
- Are insulation upgrades included to meet current Building Regulations?
- Is scaffolding included if required?
- What warranty is offered on materials and installation?
- Can you see previous EPDM jobs they’ve installed locally?
These checks help ensure you're comparing like-for-like quotes and getting a roof that performs well long term.
Quick Verdict
EPDM costs more upfront than basic felt in many cases, but thanks to its durability and low maintenance needs, it’s often the more cost-effective and reliable flat-roofing choice over the life of the roof.
