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

Understand roof issues raised in surveys, common causes, repair costs, and when to get a roofer’s inspection.

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.
