Which flat roofs are common in Wrexham?
Flat roofs in Wrexham sit on newer estates where the first extension roofs are now being replaced, terraced streets with flat-roofed rear kitchens and bathrooms and bungalows with flat-roofed side extensions and dormers. 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 does a flat roof survey take and how long is it valid?
A survey of a typical garage or extension roof usually takes an hour or two on site. Larger, higher or multi-area roofs take longer, and the written report follows afterwards.
A survey describes the roof on the day it was inspected. It stays a useful baseline for planning, but roofs change, particularly older ones and after a hard winter or a storm. If you are using a report to plan a replacement some time later, or after a fresh leak, a short follow-up check is sensible. For roofs you manage over the long term, a regular inspection backed by the maintenance checklist picks up problems early.
Will the survey tell me whether to repair or replace?
Yes. That is one of the main things a survey is for. Isolated damage on a dry, sound roof points to repair. Wet insulation, a soft deck, widespread cracking or repeated leaks point to replacement.
The report puts that recommendation in context, including the roof's age, its system, how long a repair would be likely to hold and whether the thermal upgrade rules would apply to a replacement. If you decide to replace, it also helps you choose between stripping the roof back and overlaying it. Our repair or replace guide and overlay or strip guide go into more detail.

Can a survey tell me if my flat roof has condensation rather than a leak?
It can often point to it. Damp that appears in cold weather without rain, a cold roof build-up with little ventilation and a dry covering above the damp all suggest condensation rather than a leak.
Is a core sample damaging to the roof?
It's a small, deliberate opening that is sealed again with compatible material before we leave. It shouldn't affect how the roof performs.
Do I need a roof survey when buying a house with a flat roof?
It's worth considering if the general survey flags damp, ponding or an ageing covering, or if the roof is large. A specific flat roof report gives you a clearer idea of what work may be needed and what it might cost.
