Flat roofing specialists serving Fareham, Portchester and south Hampshire. Fareham's large post-war and 1960s to 80s suburban estates carry a high volume of original flat-roofed garage and extension additions that have reached or exceeded their design life. GRP fibreglass, EPDM rubber and felt flat roofing systems — with free quotes and honest material advice.
GRP fibreglass is specified on most Fareham 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 Fareham 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 Fareham is dominated by two demand sources. The large post-war estates across Cams, Portchester Road and the northern suburbs carry original felt flat roofs on garage and porch additions built in the 1960s and 70s — now 50 to 60 years old. The second is rear extension flat roofs added to 1930s and post-war semis from the 1980s onwards, many now on their second or third felt layer.
Fareham's harbour microclimate adds a humidity factor higher than inland towns, slightly accelerating degradation of older felt membranes. We recommend GRP or EPDM over standard felt for Fareham flat roofs — the performance difference in a moderate coastal-adjacent environment justifies the additional upfront cost.
Flat roof system costs in Fareham: GRP fibreglass £90 to £130 per m2 — 25-year guarantee. EPDM rubber £70 to £95 per m2 — 20 to 25-year life. Torch-on felt £45 to £65 per m2 — 10 to 15-year life in Fareham conditions.

"Garage flat roof on our Cams Estate property — original felt from the 1960s, patched twice. GRP replacement in a day. Completely watertight and the 25-year guarantee gives us peace of mind."
"Rear extension flat roof had a slow leak for two years. Deck was still sound so they repaired it with EPDM overlay rather than a full replacement — saved us money and they were honest about why."
"Three quotes for our Fareham garage roof. Portsmouth Roofing were the only ones who explained the difference between the systems properly. Went with GRP. Job done in a day."
GRP fibreglass 25 to 30 years. EPDM rubber 20 to 25 years. Torch-on felt 10 to 15 years in Fareham's harbour-adjacent conditions. GRP or EPDM recommended for best long-term value.

Fareham sits at the head of Portsmouth Harbour where tidal air cycles inland daily, creating sustained humidity even without direct Solent frontage. North-facing elevations here stay damp significantly longer after rain than equivalent properties 5 miles inland.
The 1930s semi belt along Gosport Road and the post-war Catisfield estates form the bulk of Fareham's residential stock — two housing eras that present distinct roofing failure profiles simultaneously.
Fareham's post-war garage flat roofs are predominantly from the 1960s estate builds — now 60-plus years old. The deck condition on these is almost always compromised and must be assessed before any overlay system is specified. Every job we carry out in Fareham 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.
