Which flat roofs are common in Cumbria?
Flat roofs in Cumbria sit on lock-up garage blocks on estates, 1930s semis with flat-roofed garages and kitchen extensions and bungalows with flat-roofed side extensions and dormers. 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. Approximate 1991–2020 regional averages based on Met Office data.
Building regulations in England
Replacing more than half of a roof over a heated room usually counts as renovating a thermal element, so it is insulated to current standards and notified to building control. Renovated roofs over heated rooms are insulated to around 0.16 W/m²K where that's feasible, and new extension roofs are built to 0.15 W/m²K. In Cumbria the application goes to Cumberland Council and Westmorland and Furness Council. More on the rules.
How long will a flat roof repair last?
A well-made repair on a roof that is otherwise sound should last as long as the covering around it. It can't add years to the rest of the roof, though.
If your felt roof is twenty years old, a perfect patch still leaves twenty-year-old felt around it, and the next weak point will appear in its own time. That is why we give you an honest view of how much life the roof has left, so you can decide whether a repair now and a planned replacement later is better value than replacing straight away.
Simple care helps any repair last. Clearing leaves from outlets and gutters, keeping people off roofs that aren't designed for foot traffic, and looking over upstands and edges after storms all catch small problems before they reach the ceiling. Our maintenance guide lists the checks worth doing each year.
Should I repair or replace my flat roof?
Repair it if the defect is isolated and the rest of the roof is sound, dry and still well within its working life. Replace it if leaks keep coming back, cracking or blistering is widespread, the insulation is wet or the deck feels soft underfoot.
A useful test is to ask whether a repair would still look sensible if a second leak appeared somewhere else a few months later. On a roof near the end of its life, patching one split tends to move the problem rather than solve it, and repeated call-outs soon add up to a large share of the cost of a new roof. On a roof that is a few years old with one storm-damaged lap, a repair is the right answer and we will say so.
Our repair or replace guide sets out the signs in more detail, and the lifespan guide gives typical service lives for each system.

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.
Can a GRP roof be repaired?
Yes. The damaged area is ground back, new resin and matting are laid over it and a matching topcoat goes on top. Cracks that keep reappearing along the same line often point to movement in the deck, which needs fixing first.
Why does my flat roof only leak in heavy rain?
Usually because water only reaches a weak point when it builds up: a partly blocked outlet, a low spot where water ponds, or an upstand that is too low for the depth of water. Wind-driven rain against a wall above the roof is another common cause.
