Flat Roofing Specialists
Flat roofs are deceptively technical — the wrong system, a poor detail at the abutment, or a single bad join is the difference between a roof that lasts 30 years and one that leaks within five. Prestige Roof Works installs and repairs all major flat roofing systems across South Wales, from small porches and garage roofs to large commercial decks. Every installation is carried out by trained operatives, uses materials we trust long-term, and is backed by a written workmanship guarantee.
- EPDM, GRP fibreglass and torch-on felt — system matched to your roof

What Our Flat Roofing Customers Say
"Had a felt extension roof leaking for years — patches every winter. Prestige stripped it, upgraded the insulation and installed a one-piece EPDM. Two winters in, completely dry and looks miles better."
— Catrin Morgan, Cardiff
"Garage roof was sagging and soaked. They replaced the deck where it had rotted and fitted a fibreglass GRP roof. Seamless finish, neat trims and a proper twenty-year guarantee on the membrane."
— Paul Griffiths, Newport
"Quoted three roofers for a flat roof on a large rear extension. Prestige were the only ones who actually walked me through which system suited the pitch and drainage. Tidy job, on time, on budget."
— Sian Roberts, Swansea
