When is a repair the right answer in Lancaster?
In a place like Lancaster, flat roofs usually sit over garages, rear extensions, dormers and bays, and they take the full force of the weather with little margin for error. A single failed lap or a cracked upstand is enough to let water into a kitchen, bedroom or hallway below.
Lancaster's flat roofs are mostly on newer estates where the first extension roofs are now being replaced, with plenty on 1960s and 1970s link-detached houses with flat-roofed garages and porches too. The North West is one of England's wetter regions, averaging roughly 1,290 mm of rain a year, so falls, outlets and well-detailed upstands matter more than the membrane colour.

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?
- Inspection of the whole roof, not just the wet patch
- Repairs with materials compatible with your roof system
- Outlets and gutters cleared while we're on the roof
- Leak path traced from the stain back to the entry point
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.
