When is a flat roof survey worth it in Cobham?
Landlords and managing agents in Cobham often need a written record of a roof's condition, for budgeting, for leaseholders, or to show a problem has been looked at properly. A survey report gives them a clear basis for deciding when to repair and when to replace.
Around Cobham, flat roofs are common on shops with flat-roofed rear stores below flats and on 1930s semis with flat-roofed garages and kitchen extensions. Much of the South East sits in the drier Thames catchment at roughly 730 mm of rain a year, so the usual failures are at joints, upstands and outlets rather than from sheer volume of rain.
How much does a flat roof survey cost in Cobham?
Guide price in Cobham: £170–£330 for a condition survey and leak investigation, including VAT at South East rates. We confirm the price once we've traced the leak or seen the damage.

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?
- Free quote if replacement is the right answer
- Core samples where readings need confirming
- Moisture meter readings across the roof
- Checks on walls, copings and trays above the roof
Building regulations in England
Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.

How much does a flat roof survey cost in Cobham?
£170–£330 for a condition survey and leak investigation, at South East guide rates including VAT. We confirm the price once we've traced the leak or seen the damage.
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.
Do you survey commercial and block roofs?
Yes. We survey flat roofs on shops, offices, units, blocks of flats and HMOs, with the report structured so a landlord, managing agent or owner can plan and budget the work.
