Flat Roofing in Southampton
Flat roofs on extensions, garages and dormers take a lot of weather for their size. We install and replace modern flat roofing systems that stay watertight for years, not months.
- Extension, garage and dormer flat roofs
- Modern felt, EPDM and GRP systems
- Proper falls so water always drains away
- New edge trims, outlets and flashing
Flat Roofing done properly
Why flat roofs fail
Most flat roofs leak because of poor falls, tired felt, or badly detailed edges and upstands where they meet a wall. We address the whole roof, not just the surface, so the new roof actually performs.
The right system for the job
Depending on the roof and your budget we fit high-performance felt, rubber EPDM or fibreglass GRP. We will talk you through the options and recommend what gives you the best life for your money.
