Local roofing specialists serving Southwick and the BN42 postcode. Victorian and Edwardian along A270 corridor, post-war residential estates, South. Free quotes, no call-out fee.
Victorian and Edwardian along A270 corridor, post-war residential estates, Southwick Marina modern. The dominant roofing issues in Southwick are: Lead flashing failure on Victorian terraces; post-war concrete tile nail sickness developing; marina-adjacent properties see above-average tidal spray exposure.
Harbour mouth position adds tidal spray to standard coastal exposure; Adur estuary to the west creates combined influences. We apply appropriate coastal-grade materials and specification on every Southwick job as standard — not as a premium upcharge.
Felt flat roof lifespan in coastal West Sussex is 8–12 years versus 15–20 inland — salt air attacks the bitumen surface and UV on the south coast accelerates embrittlement. GRP is completely impervious to both. It has no joints or seams, which eliminates the primary failure mode of felt. Over 30 years, GRP installed once costs less than felt replaced two or three times.
Deck assessment takes 20 minutes. If the deck is sound, overlay saves cost and disruption. If it is compromised, strip-back is the only correct answer. We will not overlay onto a rotten deck — it traps moisture and the new membrane fails from below. We explain exactly what we find before quoting.

Every flat roof job begins with structural deck inspection. If the plywood or OSB substrate is sound, we can overlay GRP directly. If deck has rotted from water ingress, we strip to the joists and relay new deck before applying GRP.
Fibreglass matting saturated with polyester resin is applied to the deck in a seamless layer. Gel coat topcoat applied same day. Fully weatherproof within 24 hours. No joints, no seams.
Minimum 1:80 fall on all flat roofs. Upstands minimum 150mm at all perimeter edges — 200mm on coastal-facing properties. Outlet positions designed for peak West Sussex rainfall.
