When is a flat roof survey worth it in Dundonald?
Buyers in Dundonald 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.
Around Dundonald, flat roofs are common on terraced streets with flat-roofed rear kitchens and bathrooms and on low-rise post-war blocks of flats. Northern Ireland averages roughly 1,150 mm of rain a year, spread over many wet days, so a roof that sheds water quickly to clear outlets lasts far longer than one that holds puddles.
How much does a flat roof survey cost in Dundonald?
For Dundonald we use Northern Ireland rates: £130–£260 is the guide for a condition survey and leak investigation, VAT included. We confirm the price once we've traced the leak or seen the damage.
| Job | Guide price inc VAT |
|---|---|
| Condition survey and leak investigation | £130–£260 |
| Localised patch repair | £130–£440 |
| Upstand or flashing repair | £220–£570 |
| Emergency temporary weatherproofing visit | £160–£400 |
What does a flat roof survey report cover?
The report sets out what the roof is, what condition it is in and what we recommend, in plain language.
- The roof system, approximate area and how the roof is built, as far as can be seen.
- The condition of the covering: splits, blisters, crazing, lost chippings, open laps and wear.
- Upstands, flashings, edge trims and rooflights.
- Falls, ponding and the state of outlets and gutters.
- Moisture readings and the findings of any core samples.
- The likely cause of any leak, and how confident we are in it.
- Recommended action, ranked by urgency, with guide costs.
We are clear about what we could and couldn't see. A survey can't inspect hidden timbers without opening them up, and we will say where a finding is an inference rather than a direct observation.
What's included?
- Plain written report with ranked recommendations
- Free quote if replacement is the right answer
- Inspection of the covering, upstands, edges and outlets
- Checks on walls, copings and trays above the roof
Building control in Northern Ireland
In Northern Ireland, Technical Booklet F1 sets roof insulation at 0.18 W/m²K when a roof over a heated room is renovated or newly built, where that's feasible. The district council's building control should be contacted before work starts, and we prepare the details it asks for. More on the rules.

£130–£260 for a condition survey and leak investigation, at Northern Ireland 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.
Does a moisture meter work on every flat roof?
Not equally well. Readings vary with the material, and some coverings, foils and metal layers can affect them, which is why we treat readings as a guide and confirm doubtful areas with a core.
