When is a repair the right answer in Lancing?
In a place like Lancing, 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.
Lancing's flat roofs are mostly on terraced streets with flat-roofed rear kitchens and bathrooms, with plenty on 1960s and 1970s link-detached houses with flat-roofed garages and porches too. Much of the South East sits in the drier Thames catchment at roughly 730 mm of rain a year, so the usual failures are at joints, upstands and outlets rather than from sheer volume of rain.
How much does a flat roof repair cost in Lancing?

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.

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.

How much does a flat roof repair cost in Lancing?
£170–£550 for a localised patch repair, at South East guide rates including VAT. We confirm the price once we've traced the leak or seen the damage.
Can you repair the roof if the ceiling is already damaged?
Yes. The roof is fixed first so the ceiling can dry out, and then a plasterer or decorator can make it good. Any wet insulation within the roof should be checked, as it may need replacing.
Do I need building regulations approval for a flat roof repair?
Not usually for a patch repair. Replacing a large part of the covering over a heated room is treated differently and can bring in the thermal upgrade rules.
