Should I Worry if My Survey Says the Roof is Nearing End of Life?

Why it appears

Surveyors comment on age and visible wear. “Nearing end of life” means the covering is old but still serviceable, not necessarily failing. Under the RICS Home Survey Standard (2019, section 4.10), surveyors are required to describe the condition and maintenance needs of building elements but not to predict their remaining lifespan or performance.

Typical Findings

  • Missing or slipped slates/tiles

  • Damaged flashing or valley gutters

  • Ponding on flat roofs

  • Blocked rainwater outlets

Surveyors inspect from ground or loft only — no ladders or lifting tiles. In recent years, most surveyors bring a drone to inspect the rooftop as well. 

Likely minor

  • Original clay or slate roof with only local moss or slipped tiles.

  • No internal damp staining.

  • Regular maintenance expected.

Potential red flags

  • Missing or cracked tiles, sagging rafters, or active leaks.

  • Flat roofs showing blistering or ponding water.

  • Multiple Condition 3 ratings for roof structure and coverings.

Recommended Action

  • Commission a roofing inspection (£150–£300)

  • Get a quote for any urgent repairs

  • Check loft for leaks, daylight, or rot

Repair Type

Typical Cost (London) excluding VAT

Minor slate repairs

£250–£600

Lead flashing

£300–£800

Flat roof re-felt

£1,000–£2,500

Full re-roof (terrace)

£4,000–£8,000

Risks of not addressing it:

Neglected roof defects can lead to leaks, rot in roof timbers, and internal dampness — often multiplying repair costs over time.

What to do next
