Which flat roofs are common in Gloucestershire?
Flat roofs in Gloucestershire sit on lock-up garage blocks on estates, terraced streets with flat-roofed rear kitchens and bathrooms and 1960s and 1970s link-detached houses with flat-roofed garages and porches. The South West averages roughly 1,260 mm of rain a year and many roofs face wind off the Atlantic, so we specify fixings and edge details for wind uplift as well as drainage. Approximate 1991–2020 regional averages based on Met Office data.
Building regulations in England
Replacing more than half of a roof over a heated room usually counts as renovating a thermal element, so it is insulated to current standards and notified to building control. Renovated roofs over heated rooms are insulated to around 0.16 W/m²K where that's feasible, and new extension roofs are built to 0.15 W/m²K. In Gloucestershire the application goes to Gloucester City Council, Cheltenham Borough Council, Stroud District Council and 3 other councils. More on the rules.
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 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 much does a flat roof survey cost in Gloucestershire?
£150–£310 for a condition survey and leak investigation, at South West guide rates including VAT. We confirm the price once we've traced the leak or seen the damage.
Which council handles building control for a flat roof in Gloucestershire?
It depends on where the roof is: in Gloucestershire that's Gloucester City Council, Cheltenham Borough Council, Stroud District Council and 3 other councils. Replacing more than half of a roof over a heated room usually counts as renovating a thermal element, so it is insulated to current standards and notified to building control. We confirm which applies at the survey.
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.
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.
