Can You Install Solar Panels on an Asbestos Roof?
Short answer: yes – but not directly.
If your home in Essex, Suffolk or Kent has an asbestos cement roof (common on garages, outbuildings and some older properties), solar is still very much an option. However, it requires specialist handling, strict safety procedures and often a replacement or over roofing solution before installation.
At SolarTherm UK, we regularly advise homeowners on how to safely and cost effectively transition from asbestos roofing to a modern solar ready system.
Why Asbestos Roofs Require a Different Approach
Asbestos containing materials (ACMs) were widely used in UK construction before being banned due to links with serious health conditions when fibres are disturbed.
Installing solar panels typically involves drilling, mounting brackets and applying load to the roof structure. With asbestos, that presents two key issues: health risks if fibres are released and structural limitations of older cement sheets. Due to this, you cannot install solar panels directly onto an asbestos roof safely or legally without proper mitigation.
Your Options for Solar on an Asbestos Roof
Asbestos Roof Removal and Replacement (Recommended)
This is the most common and future proof route:
- Safe removal by licensed asbestos contractors
- Replacement with a modern, durable roofing system (e.g. metal sheet or composite panels)
- Solar installed on a structurally sound, compliant roof
This maximises system lifespan, ensuring compliance with UK health and safety regulations. Long term, property value and insurability should also improve.
Over-Cladding (Encapsulation)
In some cases, a new roof layer can be installed over the existing asbestos roof without disturbing it, creating a safe barrier and allowing solar to be mounted to the new structure. However, it is not always structurally viable and requires a detailed survey, load calculations and expert advice.
Ground Mounted Solar (Alternative Option)
If roof work is not viable, ground mounted systems can be installed in gardens or land areas, ideal for rural properties with plenty of available land and avoids roof disturbance completely.
Costs: What Should You Expect?
Costs vary depending on roof size, condition and chosen approach. Typical ranges:
- Asbestos removal: £50-£100 per m²
- Roof replacement: £80-£150 per m²
- Solar system (4kWp): £6,000-£8,500
While this adds upfront cost, it often represents better long term value by combining roof renewal with energy savings.
Is It Worth It?
For most homeowner, the answer is yes. Combining asbestos roof replacement with solar installation allows you to:
- Eliminate a hazardous material
- Future proof your property
- Reduce electricity bills immediately
- Increase EPC rating and potentially property value
With energy prices remaining volatile, solar remains one of the most reliable long term investments for UK households.

FAQs
Can I install solar panels directly onto an asbestos roof?
No. It is unsafe and not compliant with regulations. The roof must either be removed or encapsulated first.
Do I need planning permission?
In most cases, solar is permitted development. However, asbestos removal and roof replacement may involve additional considerations.
How long does the process take?
Typically 2–4 weeks including removal, roofing, and solar installation.
Will removing asbestos increase my property value?
Yes. It improves safety, mortgage ability, and buyer confidence.
Is asbestos always dangerous?
It is safe when undisturbed, but any work (like solar installation) increases risk—hence the need for controlled handling.
