The Hidden Health Crisis Sitting on Millions of British Driveways

UK Asbestos Garage Roof Dataset (2025)

Asbestos Garage Roof on UK Driveway

Why This Page Matters

Despite being banned in 1999, asbestos still hides in millions of UK garage roofs.

Yet, until now, no one has published a real-world, garage-specific dataset showing how many homes still contain asbestos, why it remains ignored, and how homeowners are responding.

This is the most complete asbestos garage roof dataset available anywhere online – drawing from:

  • 17,000+ homeowner enquiries since 2020
  • 4,186 quotes analysed (May 2024–April 2025)
  • 1,000+ completed garage roof replacements
  • Verified insights from HSE, FOIs, housing surveys and live UK data

Homeowner Behaviour & Triggers: Top 3 Reasons for Replacement

1. Roof Started Leaking

This is the number one cause of action.

2. Health Concerns

Most homeowners take action after discovering the risks of asbestos online.

3. House Sale in Progress

Buyers request quotes to renegotiate price.

The Legal Loophole Most Homeowners Don’t Know

  • There is no legal obligation to remove an asbestos garage roof
  • You can still sell a house with one – but expect delays or a lower purchase price
  • DIY removal is common – but illegal without licensed disposal

Danmarque Garages are fully licensed (Environment Agency CBDU63693) and provide waste consignment notes for every removal.
