Post-war 1945–1970 residential estate housing with some interwar infill, gentle rising ground at 25–40m. Moderate elevation above coastal plain; wind exposure above seafront level. Free quotes, no call-out fee across BN14.
Offington is estate country: post-war residential estate housing from 1945 to 1970 with some interwar infill, on gently rising ground at 25 to 40 metres. Roofs here are typically concrete interlocking tile now 55 to 80 years old, with nail sickness developing on the older stock. We work across the estate off Offington Lane, the streets near Offington Avenue and the higher ground toward Durrington.
On rising ground above the coastal plain, Offington sits above seafront level but below the escarpment — moderate, steady wind exposure that works ageing ridge mortar loose over time. Day to day, the flat-roof failures we see most are ponding and blistered felt, failed seams and upstands and lifted edges after gales. In Offington, that means post-war estate spec — nail-sickness re-fixing and ridge re-bedding matched to concrete interlocking tile.
GRP fibreglass is our standard specification for all flat roofing in coastal West Sussex. It lasts 40–50 years versus 8–12 for felt in coastal conditions.
Every flat roof job begins with structural deck inspection. If the deck is compromised, we replace it before applying GRP — never overlay onto rot.
Minimum 1:80 fall on all flat roofs. Minimum 150mm upstands — 200mm on coastal-facing properties.
Typical timescales for Offington properties. Every roof differs — your written quote confirms the schedule for your job.
| Timescale | Stage | What happens |
|---|---|---|
| 1 day | Small flat roof | A porch, bay or small garage in GRP or EPDM, weather permitting. |
| 1–2 days | Typical extension | Single-storey rear extension or larger garage roof, strip to finish. |
| 2–4 days | Warm-roof upgrade | Deck repair plus insulation build-up and new membrane. |
| Within a week | Quote to completion | Usual turnaround for a standard flat-roof replacement. |
GRP and EPDM systems are specified for two decades-plus of coastal exposure.
Our installation backed in writing, on top of the material warranty.
Seamless systems mean no felt laps — the point where old flat roofs always failed.
