Post-war 1950s–1970s residential estate on the lower Downs fringe, 25–45m elevation. Above coastal plain; moderate wind exposure; north-facing slopes see above-avera. Free quotes, no call-out fee across BN13.
Roofing Hill Barn means a post-war residential estate from the 1950s to 1970s on the lower Downs fringe, between 25 and 45 metres. Expect concrete interlocking tile now 55 to 75 years old, with nail sickness developing across the estate across the area. We work across the estate off Hill Barn Lane, the streets near the recreation ground and the higher ground toward Salvington.
Above the coastal plain with moderate wind exposure, Hill Barn's north-facing slopes see above-average moss accumulation — the estate's defining maintenance issue alongside ageing concrete tile. On this stock, the flat-roof failures we see most are ponding and blistered felt, failed seams and upstands and lifted edges after gales. In Hill Barn, that means estate-scale work — nail-sickness re-fixing and soft moss removal matched to post-war concrete 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 Hill Barn 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.
