Finding
Asbestos cement roof
What this usually means
Asbestos cement was used widely for outbuilding, garage and shed roofs pre-1999. Bonded asbestos cement is lower risk than friable forms but still requires licensed handling for removal.
Why it matters
Removal cost is material on outbuildings. The presence affects insurance for fire and storm damage.
Ask your surveyor
- Check:Where is the AC roof located?
- Check:What condition are the sheets in?
Ask the seller
- Check:Has the AC roof been disturbed or repaired?
- Check:Is there an asbestos register?
Next steps
- •Get two written quotes from local trades before negotiating with the seller.
- •Speak to your mortgage broker before exchanging if the finding affects mortgageability.

How MyPropertyScan produces this guide, and what it is not
Published by MyPropertyScan and written by Ziad Nasr, who is accountable for its accuracy. No page here is written or reviewed by a chartered surveyor, conveyancer or regulated adviser, and we do not claim otherwise.
This page is not:
- Chartered surveying: we do not inspect properties or produce RICS Home Survey reports
- Legal advice: we do not act as conveyancers or advise on title, tenure or contracts
- Mortgage or insurance advice: we are not regulated by the FCA and give no recommendations
Figures and process steps come from the published UK datasets and standards listed on this page, not from professional practice. Pages are updated when source coverage, survey cost assumptions, or lender and legal requirements materially change. Dataset limitations are set out on the methodology page.
