Electronic leak detection to pinpoint holes in flat roof membranes in Walter's Ash, carried out by an experienced roof surveyor. Every survey comes with a written report and photographs.
- Leaks that return after repairs
- Leaks through a flat roof with no obvious cause
- New membranes needing a check before handover
Electronic leak detection in Walter's Ash
Water can travel under a flat roof membrane before it shows inside. So the stain inside rarely sits under the hole. ELD tests the waterproofing directly, to find where it has been breached. It’s testing only and leave the repair to your roofer. On suitable roofs, it replaces guesswork with a located breach. The results then follow in a written report with photos. We survey single-ply roofs, liquid-applied waterproofing and flat roof membranes, and people most frequently book us about new roofs to check before paving or planting and punctures from foot traffic or tools.
In a small place like Walter's Ash, a flat roof can stand in the open, so edges, upstands and laps take a beating. Older felt roofs, often around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are normally the first part of a flat roof to go.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. You will know exactly what was inspected and what wasn’t.

What we look for on each type of roof
Green and ballasted roofs
Testing before planting or ballast goes on is simpler.
Inverted and paved roofs
On inverted roofs, insulation sits above the membrane and that changes how testing works.
Local flat roofs in Walter's Ash
With Hughenden Manor about 2.2 miles south-east, Walter's Ash sits in an area with a long building history. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material. Some villages in Buckinghamshire still have thatched roofs. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If you own a rental within reach of Saunderton station, the flat roof over a let home is worth a look before it becomes a tenant complaint. For an older house near a landmark such as Church of St Botolph, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.

What else we do in Walter's Ash
What we do, step by step
The visit typically starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. In total, it takes as long as needed for the size of the roof and how it’s built, which we set out in the quote. Somewhere like Walter's Ash needs a little journey planning: let us know about lanes, gates and parking. On the day, we inspect whatever is safely visible, inside and out.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- A report with photographs shows where each breach is.
How to prepare
- Let us know about parking near the property
- Gather any invoices or paperwork from past roof work
- Note where any stains or damp appear

Tips from our surveys
These tips come from what we see on roofs every week, before and after a survey:
- Test new membranes before covering them
- Have roof specifications to hand
- Keep outlets clear of debris
- Note where leaks show inside and when
File the report with your roof paperwork. It shows the condition of the membrane on that date.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.
Signs you need electronic leak detection in Walter's Ash
A breach can be left during installation. Testing before the roof is covered or handed over helps find them.
These are some of the problems a survey can pick up:
- New membranes needing a check before handover
- Leaks showing away from the breach
- Leaks that return after repairs
- Leaks under green or ballasted roofs
For businesses in and around places like Eden, a flat roof over a business is out of sight and out of mind until it leaks.
Questions to ask before booking
- Whether you get a written report with photos
- What happens after the report arrives
- Will they check the loft as well as the outside?
- Their track record with similar roofs
What we cannot see
No survey can tell you everything, and we’d rather be clear about that before booking. Bear these in mind:
- Moisture spread under the membrane
- Parts of the roof covered by fixed equipment
- Carrying out the repair work

What will the report tell me?
It sets out what we found, why it matters and what we recommend, backed by photos. Anything we couldn’t see safely is noted too.
Is this a RICS survey?
No. This is a survey of the roof only, and it is not a RICS Level 2 or Level 3 survey. Many buyers have both.
What if it rains on the day?
It can, depending on the survey. Drones cannot fly safely in high wind or heavy rain, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. If the conditions are not right, we’ll talk to you about another date.
Can you survey at the weekend?
