Flat roofing specialists serving Gosport and the peninsula. Gosport's coastal position makes material specification critical — UV exposure and salt air degrade standard felt faster here than inland. We install GRP and EPDM systems built to perform in coastal conditions, with free quotes and honest system advice.
GRP fibreglass is specified on most Gosport flat roofs particularly south and west-facing positions with direct sun and salt exposure. EPDM for larger areas. Standard felt not recommended for exposed positions.
We survey the deck as part of every Gosport flat roof survey. Any softness, rot or structural movement is identified and included in the quote upfront. No mid-job surprises.
GRP from 95 pounds per m2 with a 25-year guarantee. EPDM from 75 pounds per m2 with a 20 to 25-year life. Standard felt from 50 pounds per m2 with a shorter coastal life. System must be correct for position.
Flat roofing in Gosport requires the same coastal specification as Portsmouth — GRP or EPDM are the right systems for exposed and semi-exposed positions on the peninsula. Standard felt is not recommended for any Gosport flat roof with a direct south or west facing aspect. UV and salt at this location degrade felt faster than the manufacturer's quoted life assumes.
The demand for flat roof replacement is concentrated in two areas: the Bridgemary and Rowner post-war estates, where original garage and porch flat roofs from the 1960s and 70s are consistently failing, and the Lee-on-the-Solent seafront properties, where flat roof extensions face the most aggressive coastal conditions on the peninsula.
Flat roof costs in Gosport: GRP fibreglass £95 to £135 per m2 — 25-year guarantee. EPDM rubber £75 to £100 per m2 — 20 to 25-year life. Felt not recommended for exposed Gosport coastal positions.

"Garage flat roof in Bridgemary — original felt from the estate build era. Portsmouth Roofing recommended GRP for the coastal position. Fitted in a day, 25-year guarantee."
"Lee-on-the-Solent extension flat roof — previous felt had lasted 8 years before failing. EPDM replacement, much better specification for the seafront position."
"Gosport town centre property — rear flat roof had been patched three times. Portsmouth Roofing surveyed the deck, found it was still solid and quoted an EPDM overlay. Honest assessment."
Gosport's coastal UV and salt air exposure degrades felt membranes faster than the manufacturer's standard life estimate. GRP or EPDM will outlast felt by 10 to 15 years minimum on exposed peninsula positions.
GRP garage roof (25 to 35m2): £1,900 to £3,800. EPDM: £1,600 to £3,000. Free quotes on all work.

Gosport's peninsular enclosure by salt water from three directions simultaneously creates the most aggressive corrosion environment in Hampshire. Every roof surface faces salt air regardless of which direction it faces — there are no sheltered positions on this peninsula.
Victorian and Edwardian Alverstoke and the historic town centre sit alongside the large Bridgemary and Rowner post-war estates — two completely different housing profiles with entirely different failure modes presenting simultaneously.
On directly exposed Gosport positions — Lee-on-the-Solent, the harbour waterfront, and exposed Bridgemary elevations — GRP is the only flat roof specification we use. EPDM on sheltered rear positions only. Every job we carry out in Gosport is specified for these specific conditions — not a generic Portsmouth-wide approach.
No call-out fees. No obligation. Just an honest quote from a local Portsmouth roofer.
