When is a flat roof survey worth it in Gelligaer?
Buyers in Gelligaer sometimes find a general survey flags a flat roof as a concern without saying much more. A specific flat roof survey fills that gap, describing the condition and likely cost of any work so it can be factored into the decision.
In a town like Gelligaer, flat roofs are commonly found on terraced streets with flat-roofed rear kitchens and bathrooms or newer estates where the first extension roofs are now being replaced. 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.
How much does a flat roof survey cost in Gelligaer?
Guide price in Gelligaer: £140–£280 for a condition survey and leak investigation, including VAT at Wales rates. We confirm the price once we've traced the leak or seen the damage.

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.
What's included?
- Inspection of the covering, upstands, edges and outlets
- Checks on walls, copings and trays above the roof
- Plain written report with ranked recommendations
- Core samples where readings need confirming
Building regulations in Wales
The Welsh Approved Document L applies. Renovating more than half of a roof over a heated room means upgrading it to around 0.16 W/m²K where feasible, and new extension roofs are built to 0.13 W/m²K. Welsh Government guidance is that most re-roofing needs building control approval, so check whenever more than a quarter of a roof is replaced or repaired. We deal with the application as part of the job. More on the rules.

How much does a flat roof survey cost in Gelligaer?
£140–£280 for a condition survey and leak investigation, at Wales guide rates including VAT. We confirm the price once we've traced the leak or seen the damage.
Can you trace a flat roof leak without opening the roof up?
Often, yes. Careful inspection and moisture readings can usually locate the problem area. Where they can't, a small core sample is the most reliable way to confirm what is happening under the covering.
Can a survey tell how old my flat roof is?
Only approximately. The type of covering and its condition give a reasonable estimate, but paperwork such as an invoice or guarantee is the only reliable record.
