Survey found roof problems: what buyers should do next
Roof findings range from routine maintenance to major water-ingress risk. The key is to separate covering wear, structural roof issues, chimney/leadwork defects and active leaks, then decide whether you need a roofer, further survey or price adjustment before exchange.

Red flags
- Active leaks, stained ceilings or damp roof timbers.
- Sagging ridge line, roof spread, deflection or structural movement.
- Flat roof near end of life with ponding or internal staining.
- Spray foam obscuring roof timbers and lender evidence.
Amber flags
- Missing, slipped or cracked tiles with no internal staining.
- Chimney flashing, pointing or pot defects.
- Old roof covering described as serviceable but near the end of expected life.
Green signals
- Localised maintenance items with clear roofer quote.
- Recent roof replacement with invoices, guarantees and photos.
- Surveyor confirms no current water ingress or structural concern.
Roof finding triage
| Finding | Likely follow-up | Decision impact |
|---|---|---|
| Missing/slipped tiles | Roofer quote. | Usually negotiation not walk-away. |
| Chimney flashing failure | Roofer or chimney specialist. | Can cause damp; cost before exchange. |
| Flat roof ponding | Flat-roof contractor report. | Higher if near living space or active leak. |
| Roof spread or sagging | Structural engineer or Level 3 follow-up. | Potential major decision point. |
What to do next
- Ask whether the problem is covering, structure, chimney, insulation or ventilation.
- Get a roofer quote before exchange for Condition Rating 3 roof items.
- Ask seller for roof invoices, guarantees and photos of any recent work.
- Check whether a flat roof, spray foam or structural roof issue affects lender or insurer appetite.
- Use roof quotes as evidence for renegotiation rather than guessing repair cost.
Evidence to gather
- Roofer report with photos and itemised repair scope.
- Surveyor note on whether roof structure is affected.
- Invoices and guarantees for roof covering, leadwork, chimney or flat roof works.
- Internal photos of ceiling staining or loft moisture where present.

Frequently asked questions
Should I buy a house with roof problems?
Often yes if the problem is understood and priced. Be cautious where there is active leakage, structural roof movement, hidden timbers or lender concern.
Can roof defects affect a mortgage?
Yes if the valuer thinks the roof affects value, saleability or habitability. Severe defects can trigger retention or further evidence.
Should the seller fix roof problems before completion?
Usually a price reduction is cleaner, unless the lender requires works before completion or the defect is urgent and access is straightforward.
How do I renegotiate for roof repairs?
Use a roofer quote, survey wording and photos. Ask for a reduction tied to evidence rather than a round-number discount.

Sources used
We use UK public and specialist sources where they are available. Public datasets can be incomplete, delayed, or missing for some addresses. Treat them as a starting point, not as a replacement for professional advice.
Source standard: preference goes to official government datasets, statutory bodies, professional standards, and primary dataset publishers. We cite the source family on the page and explain coverage limits rather than filling gaps with unsupported estimates.
