20th century residential in the dry valley between Worthing and Findon village, 40–60m elevation. Cold air drainage creates frost pockets; higher relative humidity than coast. Free quotes, no call-out fee across BN14.
Findon Valley is 20th-century residential set in the dry valley between Worthing and Findon village, at 40 to 60 metres. The prevailing stock is concrete interlocking on post-war stock with some clay on older properties. From the streets off Findon Road through the valley-floor residential to the north-facing slopes, the pattern holds.
The valley creates its own microclimate: cold-air drainage forms frost pockets, humidity runs higher than the coast or the ridge, and north-facing slopes stay persistently damp — ideal conditions for moss and frost damage. On this stock, the flat-roof failures we see most are ponding and blistered felt, failed seams and upstands and lifted edges after gales. Our Findon Valley approach is microclimate-aware work — moss treatment and frost-resistant detailing for persistently damp valley roofs.
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 Findon Valley 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.
