Which flat roofs are common in Conwy?
Flat roofs in Conwy sit on 1930s semis with flat-roofed garages and kitchen extensions, bungalows with flat-roofed side extensions and dormers and shops with flat-roofed rear stores below flats. 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 Conwy the application goes to Conwy County Borough Council. More on the rules.
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.
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.

Which council handles building control for a flat roof in Conwy?
It depends on where the roof is: in Conwy that's Conwy County Borough Council. 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. We confirm which applies at the survey.
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.
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.
