Flat Roofing in Broadwater

Victorian suburb of Worthing — terraced and semi-detached stock 1880–1910, some Edwardian. The dominant roofing issues in Broadwater are: Nail sickness in original Welsh slate on 110–140 year old roofs; lead flashing corrosion from coastal salt air; cast iron gutter joint failure.

Worthing inner suburb 1.5km from the Channel; full coastal salt air exposure; Victorian stock requires heritage-sensitive repair throughout. We apply appropriate coastal-grade materials and specification on every Broadwater job as standard — not as a premium upcharge.

Why GRP Outperforms Felt in Coastal Conditions

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.

GRP Overlay vs Strip-Back — How We Decide

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.

How It Works

Flat Roofing in Broadwater — Our Process

01

Deck Assessment First

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.

02

GRP Application

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.

03

Drainage and Upstands

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.
