When is a flat roof survey worth it in Richmond upon Thames?
Landlords and managing agents in Richmond upon Thames 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 Richmond upon Thames, flat roofs are common on mansard and dormer loft conversions and on shops with flat-roofed stores below flats above. The Thames basin is one of the drier parts of Britain at roughly 730 mm of rain a year, but summer heat is the bigger test here: dark membranes on south-facing roofs swing a long way in temperature.

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?
- Core samples where readings need confirming
- Free quote if replacement is the right answer
- Checks on walls, copings and trays above the roof
- Inspection of the covering, upstands, edges and outlets
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.
