Asbestos Garage Roof Encapsulation vs Complete Removal & Plastisol Steel Re-Roof (2026 UK)
Is it better to encapsulate or remove an asbestos cement garage roof before selling a house?
While elastomeric encapsulation sealant (£35/m²) is cheaper short-term for intact sheets, RICS HomeBuyer surveyors and mortgage lenders increasingly flag remaining chrysotile asbestos cement roofs on the Law Society TA6 Property Information Form. Complete removal with an EWC 17 06 05* Hazardous Waste Consignment Note (£55/m² + £285 gate fee) plus a new box-profile plastisol steel roof (+£75/m²) permanently removes the liability.
| Comparison Factor | Elastomeric Encapsulation Only | Full Removal & EWC 17 06 05* Disposal | Turnkey Removal + New Steel Roof |
|---|---|---|---|
| Typical 18m² Single Garage Cost | £630 – £780 | £1,150 – £1,350 | £2,450 – £2,750 |
| Asbestos Permanently Removed from TA6 Form? | No — Must Still Declare Asbestos Present | Yes — Cleared with Consignment Note | Yes — Cleared + 25-Yr Anti-Condensation Roof |
| Statutory Paperwork Issued | Encapsulation Maintenance Log Only | Official EWC 17 06 05* Consignment Note | EWC 17 06 05* Note + Roof Warranty |
