EPDM and fibreglass flat roofs in King's Lynn
We are based at Costessey near Norwich and reach King's Lynn via the A47, about 44 miles from Norwich. 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 quayside buildings and post-war estates. Jobs here are often within sight of the Custom House, 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 King's Lynn we regularly cover Downham Market, Hunstanton, Dersingham and Swaffham — a practical radius rather than a marketing map. Flat Roofing & EPDM enquiries here are handled the same way. Work here falls under King's Lynn & West Norfolk Borough Council and the PE30 postcode area.
Frequently working in and around Hardwick industrial estate, Nar Ouse business park, historic quayside.

Specification options
- Trims, upstands and outlets
- Edge trims, correctly formed upstands and adequate outlets — where nearly all flat roof failures actually begin.
- Falls and firrings
- Firring pieces set the fall so water leaves the roof rather than sitting on it.
- GRP fibreglass
- Laid in situ over a ply deck for balconies and anything walked on, finished with a hard topcoat.
- Warm-deck insulation build-ups
- Insulation above the deck keeps the structure warm and reduces condensation risk compared with old cold-deck details.
Flat Roofing & EPDM FAQs
- Is the roof walkable?
- GRP takes foot traffic and suits balconies and terraces. EPDM is fine for maintenance access but isn't intended as a walking surface — if you need a usable deck, say so and we'll specify accordingly.
- Do you insulate at the same time?
- We can build a warm deck with insulation above the structure, which usually makes sense if the roof is coming off anyway and the room below is cold or prone to condensation.
- 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.
- Where do you park the van and set up scaffold here?
- We agree that with you first. Around South Quay the approaches can be tight, so unloading and scaffold positions are planned before the work starts rather than sorted out on the morning.
- Do you actually cover King's Lynn, or just the Norwich area?
- We cover it. We're based at Costessey, Norwich and King's Lynn is about 44 miles from Norwich, reached on the A47. It's a normal working area for us, not an outlier.
