Flat roofing in Mattishall
Roofs in Mattishall are dominated by bungalows and 1970s estate housing. Each behaves differently once it starts to fail, which is why our flat roofing & epdm here starts with an inspection rather than a price over the phone. Breckland District Council covers the area, and we work across the NR20 postcode district. Jobs here are often within sight of All Saints church, so we allow for the narrow approaches and parking that comes with it.

Our working method
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.

Properties around All Saints church
The buildings closest to All Saints church take the brunt of the weather from that side, and they are the ones we are asked to look at most often here. The same applies along the approach to the Dereham Road corridor.
Failed upstands and trims
Most flat-roof leaks start at the edges — upstands, drip trims and the junction with the main wall — not in the middle of the roof.
Ponding water
Flats laid without enough fall hold water for days, which shortens the life of any membrane. Falls and outlet positions get reset, not covered over.
Slipped and cracked tiles
Most Mattishall call-outs start with a handful of slipped tiles that let water onto the felt below.
Practical answers before you book
- Why does water sit on our flat roof after rain?
- Insufficient fall, a sagging deck or a blocked outlet. On Mattishall extensions it's usually falls that were never set properly. We reset falls with firrings rather than lay new membrane over the same puddle.
- 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.
- 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.
- How soon can someone look at a leak in NR20?
- Call 07437 005301 and we'll arrange an inspection. We advertise a 24/7 emergency call-out for active leaks and storm damage, and we'll tell you on the phone what's realistic rather than promise a fixed time.
- 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.
Coverings suited to Mattishall
- Warm-deck insulation build-ups
- Insulation above the deck keeps the structure warm and reduces condensation risk compared with old cold-deck details.
- 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.
- Trims, upstands and outlets
- Edge trims, correctly formed upstands and adequate outlets — where nearly all flat roof failures actually begin.
