EPDM and fibreglass flat roofs in Harleston
We are based at Costessey near Norwich and reach Harleston via the A143, about 8 miles from Diss. That matters for flat roofing & epdm: it decides how quickly we can inspect, how we get materials on site, and how we sequence work on Georgian frontages and pantile roofs. Jobs here are often within sight of the Harleston Corn Exchange, so we allow for the narrow approaches and parking that comes with it.

What happens after you call
Deck inspection
We lift a section to see the deck; nothing is laid over boards that are soft or damp.
Falls and detailing set out
Firrings, outlet positions and upstand heights are agreed before the membrane arrives.
Membrane installation
EPDM, GRP or felt installed with trims and upstands dressed properly at every edge.
Water test and handover
Outlets checked under flow, edges walked, and the finished roof handed over with the system details.
Our Norfolk service radius
Working out from Harleston we regularly cover Diss, Bungay, Long Stratton and Beccles — a practical radius rather than a marketing map. Flat Roofing & EPDM enquiries here are handled the same way. Work here falls under South Norfolk Council and the IP20 postcode area.
Frequently working in and around Broad Street retail frontages, Waveney valley dairy and arable farms.
Covering Harleston and Diss
About 8 miles apart — both are normal working areas for us. Free inspection either way.
Specification options
- Torch-on felt systems
- Multi-layer bitumen for larger or awkward flats where a robust, easily repairable finish is the practical choice.
- Falls and firrings
- Firring pieces set the fall so water leaves the roof rather than sitting on it.
- EPDM rubber membrane
- One-piece rubber for extensions, dormers and garages — no field seams, and it copes well with movement.
- GRP fibreglass
- Laid in situ over a ply deck for balconies and anything walked on, finished with a hard topcoat.
Flat Roofing & EPDM FAQs
- Can you overlay the existing felt?
- Only if the deck below is dry and sound, and we'll lift a section to check. Overlaying a soft deck buys a year or two and costs the whole job again.
- Why does water sit on our flat roof after rain?
- Insufficient fall, a sagging deck or a blocked outlet. On Harleston extensions it's usually falls that were never set properly. We reset falls with firrings rather than lay new membrane over the same puddle.
- How long should a new flat roof last?
- A well-installed EPDM or GRP roof on a sound, correctly falling deck should give decades of service. What kills flat roofs early is ponding water, poor upstands and being laid over a wet deck — all avoidable.
- Can you work on commercial premises around Broad Street retail frontages?
- Yes — shops, offices, workshops, agricultural and industrial units. Work is scheduled so trading and site access carry on where possible, and larger roofs are quoted with a planned maintenance option if that's more useful than a one-off repair.
- Does the exposure here change what you'd specify?
- Sometimes. Sheltered streets can run standard details, but shared valleys, restricted scaffold or heavy moss growth all change how we'd approach the work.
