Failure of concrete and clay tile roof coverings

Technically reviewed by Savas Bulduk BSc (Hons) MRICS, Director & Chartered Building Surveyor · last reviewed 2026-07-20. General information only — not a survey of a specific property.

What it means

Clay and concrete tiles reach end of life through lamination, breakage, frost damage and fixing failure. Valleys and verges fail first. Water entry may be intermittent until underlay also fails.

What you might notice

Broken, slipped or missing tiles
Laminating clay tile faces
Moss-laden fragile tiles
Ceiling stains beneath defective slopes

Recommended next step

The proportionate instruction depends on the building, the concern and what an inspection can reasonably establish. HCS confirms the scope before you book.

Speak to a surveyor first

We confirm the proportionate instruction before quoting.

Also consider

Instruct a RICS Level 3 Building Survey — Detailed survey for older, altered, listed, non-standard or defective London property.
Not sure Level 2 or Level 3? Use the survey chooser — Use the live HCS tool for an indicative comparison, then confirm the scope before instruction.
Instruct a building pathology / defect survey — Cause-led diagnosis for a defined damp, leak, crack or fabric problem — not a full purchase survey.

From Survey Findings to Remedial Design, Tendering & Execution

Once our RICS chartered building surveyors have diagnosed the root cause of a defect through a Specific Defect & Building Pathology Investigation or RICS Home Survey, you can either instruct Hampstead Chartered Surveyors independently for JCT Contract Administration to tender the works to external contractors, or elect our joined-up group design-and-build route alongside our sister practices:

Hampstead Architecture & Planning: Architectural drawings, conservation-area and listed-building consents, structural engineering coordination, and Building Regulations packages translated directly from the survey diagnostics.
Hampstead Renovations: Principal contractor remedial execution, heritage masonry and roofing repairs, damp and timber remediation, and full residential refurbishments backed by £5M public liability, £10M employers' liability and contractors' all risks cover alongside Hampstead Chartered Surveyors' RICS-regulated Professional Indemnity Insurance (PII).

RICS Impartiality Note: Where Hampstead Chartered Surveyors acts as independent JCT Contract Administrator or Party Wall Surveyor, works are tendered strictly to independent third-party contractors in accordance with RICS conflict-of-interest governance.
