Flat Roofing Guys

14 March 2026

Wondering what EPDM rubber roofing costs in the UK? We break down supply, installation, and total costs for different roof sizes.

EPDM rubber roofing is one of the most popular flat roofing systems in the UK, valued for its durability, flexibility, and long lifespan. Here's a realistic guide to what it costs in 2026.

EPDM Installation Costs by Roof Size

  • Small garage/extension (15–20m²): £900–£1,800
  • Medium extension (25–40m²): £1,500–£2,800
  • Large extension or bungalow roof (50–80m²): £2,800–£4,500
  • Very large commercial roof (100m²+): From £5,000

What's Included in the Price

A properly quoted EPDM installation should include: stripping and disposing of the old membrane (if applicable), replacing any rotten decking, supplying and installing PIR insulation to current building regulations, the EPDM membrane itself, all trims, flashings, and edge details, and a written guarantee.

EPDM vs Other Systems on Cost

EPDM is generally comparable in price to GRP fibreglass for most domestic projects. It can be slightly cheaper on larger roofs due to the large sheet sizes available. Felt is cheaper initially but will need replacing sooner.

Getting Accurate Quotes

Always get at least three quotes for any roofing job over £1,000. Ensure every quote is in writing, specifies the brand and specification of materials, and includes a guarantee period. The cheapest quote is not always the best value.
