Flat roof repairs in King's Lynn

If your flat roof in King's Lynn has a single defect on an otherwise sound covering, a repair is usually the sensible, lower-cost choice. We fix the defect with compatible products, clear the outlets while we're up there and give you an honest view of how much life the rest of the roof has left.

When is a repair the right answer in King's Lynn?

Small businesses in King's Lynn with a flat-roofed shop, office or unit can't leave a leak running over stock or equipment. A repair stops the water at its entry point, and our inspection tells you whether the rest of the roof needs attention soon or can safely be left for now.

Around King's Lynn, flat roofs are common on low-rise post-war blocks of flats and on shops with flat-roofed rear stores below flats. The East of England is the driest part of Britain, with parts of the Anglian region around 630 mm a year, so summer heat and UV, not rainfall, do most of the ageing on a felt roof.

Why does a flat roof leak in one place but drip somewhere else?

Because water rarely comes through the ceiling directly below the hole. It gets in at one point, runs along the deck, a joist or the top of the insulation, and drips wherever it finds a low spot or a gap in the ceiling.

That is why a patch over the damp patch so often fails. Before we repair anything, we work back from the stain to the likely entry point and check the usual weak spots: upstands where the roof meets a wall, flashings and cavity trays above them, laps and seams, outlets and gutters, drip trims, rooflight kerbs, and any fixings or cables that pass through the covering. The fault is frequently at an edge or a wall rather than in the middle of the roof.

Sometimes the cause isn't the roof at all. Defective pointing, a failed cavity tray or a cracked coping above the roof can let water in behind the upstand, and condensation in a cold roof can look exactly like a leak. Our guide to flat roof leaks covers these causes. If the path can't be found by inspection, a leak tracing survey is the next step.

What's included?

  • Fixed price confirmed in writing before work starts
  • Leak path traced from the stain back to the entry point
  • Upstands, flashings, laps and seams made good
  • Repairs with materials compatible with your roof system

Building regulations in England

Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.

Will a repair affect my roof's guarantee?

It can. If the roof is still under a manufacturer's material guarantee, the repair should normally use that manufacturer's products and methods, so share any guarantee paperwork with us before work starts.

How long does a flat roof repair take?

Most small repairs take a few hours on site once the roof is dry. Larger upstand or outlet repairs can take a day or more, and setting up scaffold or access equipment adds time.
