GRP & Felt Roofing
GRP fibreglass and high-performance felt flat roof systems — installed by manufacturer-trained roofers with decades of combined experience across the South Coast. We choose the right system for your roof, not the easiest one for us.
What's included
- GRP fibreglass — seamless, glass-hard, 25-year life, walk-on finish
- Three-layer reinforced laminate over OSB3 deck
- Coloured topcoat — slate grey, anthracite, light grey, dark grey, terracotta
- Torch-on and cold-applied polyester-reinforced felt for larger commercial roofs
- Insulation upgrades to current Building Regs Part L
- Free written quotation with fixed price
GRP fibreglass is the gold standard for small-to-medium domestic flat roofs. Three layers of catalysed polyester resin and chopped-strand mat are laminated wet-on-wet over an OSB3 deck and finished with a pigmented topcoat. The result is a seamless, jointless, glass-hard surface with no laps, seams or hot bitumen anywhere.
Felt still has its place — particularly on larger commercial roofs and where budget is tight. We use polyester-reinforced, mineral-finished felts in a two- or three-layer build-up, fully bonded to insulation and properly detailed at every edge and upstand. Modern felt systems carry 15–20 year manufacturer guarantees and behave nothing like the brittle, granule-shedding felts of the 1980s.
Whichever you choose, the spec is matched to the roof — not the lowest bidder. We'll show you the data sheets and the manufacturer guarantee paperwork before you sign anything.

Frequently asked
GRP & Felt Roofing questions, answered honestly.
Is GRP slippery in wet weather?
The standard topcoat is non-slip rated. For balconies and terraces we apply an anti-slip aggregate broadcast into the topcoat for additional grip.
Can GRP be installed in winter?
Yes — minimum installation temperature is around 5°C with the right resin and catalyst mix. We adjust the chemistry to the conditions and protect the work from rain during cure.
What guarantee do I get?
Manufacturer-backed material guarantees of 20–25 years on GRP and 15–20 years on premium felt systems, plus our own written workmanship guarantee.
Verified customer reviews
What customers say about our roofing work.
Hampshire and Dorset homeowners on the work Mike and the team have carried out for them.
"Storm Isha took a dozen tiles off our roof on a Sunday afternoon. Mike answered the phone himself, was on site within two hours, tarped the whole side that night and had the permanent repair done the following Tuesday. He showed me photos before and after, talked me through the insurance claim, and didn't take a penny until I was happy. You don't get service like that any more."
"We had three roofers quote for stripping and re-covering our 1970s detached. Mike was the only one who actually got up on the roof with a ladder, lifted tiles, checked the battens and showed me where the felt had perished. His quote wasn't the cheapest but it was the only honest one. The job took five days, the skip was emptied daily, and the lads even hoovered the loft when they were done."
"Re-roofed our 1930s semi in natural Welsh slate. Mike sourced reclaimed slates that matched the next-door neighbour's roof exactly so the terrace still looks uniform. The leadwork around the chimney is a piece of art. Two of our neighbours have already booked him in."
"Our extension flat roof had been patched four times by the original builder and still leaked. Mike stripped it back to the deck, found rotten OSB nobody had mentioned, replaced it, upgraded the insulation and installed a one-piece EPDM membrane. Two heavy storms since and not a drop. Fair price, immaculate finish."
"Damp patch on the chimney breast turned out to be failed flashing and 60-year-old mortar. Mike rebuilt the top three courses, fitted new code 5 lead step flashing and repointed the whole stack. He even rebedded a wobbly pot I hadn't asked about, no extra charge. A proper tradesman."
"Two surveyors had told us our house was unmortgageable because of the spray foam in the loft. Mike removed the lot in three days, gave us a full written report with photos of every rafter, and the next surveyor signed it off without a fuss. Sale completed last week. Genuinely life-changing service."
