Guide prices including VAT at Wales rates. We confirm the price once we've traced the leak or seen the damage.

Which flat roofs are common in Wrexham?

Flat roofs in Wrexham sit on 1930s semis with flat-roofed garages and kitchen extensions, low-rise post-war blocks of flats and 1960s and 1970s link-detached houses with flat-roofed garages and porches. Wales averages roughly 1,460 mm of rain a year, among the wettest in Britain, so we design for steady run-off: proper falls, clear outlets and upstands well above the finished roof. Approximate 1991–2020 regional averages based on Met Office data.

Building regulations in Wales

Welsh guidance is that most re-roofing needs building control approval, so it's worth checking whenever more than a quarter of a roof is replaced or repaired. Renovated roofs are upgraded to around 0.16 W/m²K where feasible, and new extension roofs are built to 0.13 W/m²K under the Welsh Approved Document L. In Wrexham the application goes to Wrexham County Borough 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.
