Why does water sit on our flat roof after rain?

Insufficient fall, a sagging deck or a blocked outlet. On Letheringsett 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.

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 actually cover Letheringsett, or just the Norwich area?

We cover it. We're based at Costessey, Norwich and Letheringsett is about 1 miles from Holt, reached on the A148. It's a normal working area for us, not an outlier.

Do you clear up afterwards?

Yes. Scaffold is struck, waste removed and gutters cleared before we invoice.

What Letheringsett roofs typically need

Village properties, outbuildings and flat-roof extensions.

Outbuildings and farm structures
Barns, stores and stables are quoted alongside the house so one visit covers the holding.
Leadwork at abutments
Cottages within 1 miles of Holt often have short-life lead or cement fillets that need replacing with correctly sized lead.
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.
Rot at eaves and fascia
Persistent damp shows up first at eaves timbers on mill and estate buildings, so we check the deck edge before re-covering.

What goes on the roof

Trims, upstands and outlets: Edge trims, correctly formed upstands and adequate outlets — where nearly all flat roof failures actually begin.
Torch-on felt systems: Multi-layer bitumen for larger or awkward flats where a robust, easily repairable finish is the practical choice.
EPDM rubber membrane: One-piece rubber for extensions, dormers and garages — no field seams, and it copes well with movement.
Falls and firrings: Firring pieces set the fall so water leaves the roof rather than sitting on it.

Shelter helps, but a flat roof still lives or dies on its falls and its upstands. That is what we survey first. NR25 addresses are quoted on the same terms as anywhere else in North Norfolk District Council.
