1930s–1960s interwar semi-detached and detached estate housing. Direct south-westerly Channel exposure; full salt air loading. Free quotes, no call-out fee across BN11.
West Worthing is 1930s to 1960s interwar semi-detached and detached estate housing. Expect concrete interlocking tile now 65 to 95 years old, with widespread nail sickness developing across the area. From the interwar semis off Tarring Road through the streets toward the seafront to the stock near West Worthing station, the pattern holds.
Facing direct south-westerly Channel exposure, West Worthing takes full salt-air loading on its south-facing elevations — which is where the lead chimney flashings and ridge mortar fail first. On this stock, the flat-roof failures we see most are ponding and blistered felt, failed seams and upstands and lifted edges after gales. That is the standard we bring to every West Worthing roof.
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 West Worthing 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.
