When is a repair the right answer in Barking and Dagenham?
In a place like Barking and Dagenham, 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.
In and around Barking and Dagenham, flat roofs are typically found on Victorian and Edwardian terraces with flat-roofed back additions, and on kitchen extensions and roof terraces behind period houses. The Thames basin is one of the drier parts of Britain at roughly 730 mm of rain a year, but summer heat is the bigger test here: dark membranes on south-facing roofs swing a long way in temperature.

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.
What's included?

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.

£180–£600 for a localised patch repair, at London guide rates including VAT. We confirm the price once we've traced the leak or seen the damage.
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.
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.
