When is a flat roof survey worth it in Hemel Hempstead?
Flat roofs in Hemel Hempstead hide their problems well. A covering can look fine while the insulation beneath it is wet or the deck is softening. A survey with moisture readings and core samples shows what's happening under the surface before it reaches the ceiling.
In a large town like Hemel Hempstead, flat roofs are commonly found on lock-up garage blocks on estates or 1960s and 1970s link-detached houses with flat-roofed garages and porches. The East of England is the driest part of Britain, with parts of the Anglian region around 630 mm a year, so summer heat and UV, not rainfall, do most of the ageing on a felt roof.

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?
- Moisture meter readings across the roof
- Inspection of the covering, upstands, edges and outlets
- Checks on walls, copings and trays above the roof
- Plain written report with ranked recommendations
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.

£160–£320 for a condition survey and leak investigation, at East of England 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 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.
