Electronic Leak Detection in Darby Green
Electronic leak detection to pinpoint holes in flat roof membranes in Darby Green, carried out by an experienced roof surveyor. Every survey comes with a written report and photographs.
- Repairs that haven’t stopped the leak
- Water coming in under a flat roof
- New membranes needing a check before handover
Electronic leak detection in Darby Green: what you get
ELD finds breaches in the membrane, not every cause of water getting in. Leaks from walls, copings, rooflights or pipes need other checks. We’ll tell you if we think the leak is coming from somewhere else. It will not show water getting in through brickwork or around frames. The report makes clear what was and wasn’t tested. We’ll point you to the likely next step. We’re frequently asked to look into gaps at membrane joints and damage from equipment installers, across liquid-applied waterproofing, commercial flat roofs and flat roof membranes.
Flat roofs on exposed homes in small places like Darby Green take more wind and rain, so edges, upstands and laps take a beating. Felt roofs, which frequently last around 15–20 years, usually show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
The report records the flat roof membrane as we found it on the day. That makes it useful now and a handy reference later.

Do you need electronic leak detection in Darby Green?
Flat roof membranes can be punctured by foot traffic, dropped tools or debris. Many are tiny but water still finds them.
Things that often lead to a survey include:
- Leaks that return after repairs
- Leaks through a flat roof with no obvious cause
- Damp inside with no sign on the roof
- Damage from equipment installers
Landlords with a home close to Sandhurst station may find that the flat roof over a let home is worth a look before it becomes a tenant complaint.
Before booking any roof surveyor
- Is there a chance to talk the report through?
- When you will get the report
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- What exactly goes into their report
How the survey changes by roof type
EPDM rubber roofs
Certain rubber membranes are conductive, which can rule out some methods. We’ll tell you if yours isn’t suitable.
Single-ply membranes
Punctures from foot traffic and equipment are common on single-ply roofs. Testing helps find them.
Should I look at the roof myself first?
A DIY look is useful, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight.
Keep a simple record: dates of leaks, photos from ground level and any work done on the roof. Share it with us when booking and it will help the survey.
When you need someone else
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Fixing the holes we find
- Some conductive membranes
- The extent of water in the insulation
If you are not sure which survey you need, phone 07833 053749 or email us and we will give you a straight answer before booking. What a survey covers and doesn’t.
What this survey covers

Flat and commercial roofs around Darby Green
Some Hampshire villages still have thatched roofs. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 conservation areas. If your home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission, so check with the council.
For businesses in and around places such as Hart Shopping Centre, the flat roofs over shops and commercial units are worth checking before a leak, not after. Take a building like Potley Hill Primary School: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

Common questions in Darby Green
Is my home in Darby Green listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Is Darby Green within the area you cover?
Yes, Darby Green is on our map. A small place gets exactly the same survey as a big one.
What’s the best way to book?
To book, phone 07833 053749 or email us with the address, the type of property and what’s prompted the survey. We’ll confirm the price and agree a day with you.
Do you take photos of the roof?
Yes. We photograph the roof as we go, and they go into the written report.
What happens next?
You receive the written report by email, with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Does ELD work under paving or planting?
It can be possible, depending on the roof. Covered roofs limit the methods we can use so we check the roof first.
Does the weather affect the survey?
Light rain is usually fine; heavy rain and wind are different. In high wind or heavy rain, a drone cannot fly and access may not be safe, so we’d move the date with you.
How it works
On the day, we begin with a quick chat about the roof and anything that’s worrying you. We then inspect everything that can be seen safely, using the ground, windows, the loft and a drone where applicable. Most surveys take longer on a large roof than a small one, and the build-up of the roof makes a difference too. Around Darby Green, older homes can have small or awkward roof spaces, so tell us about the loft hatch and any ladder. We only go where it is safe.
- We start by finding out what the roof is made of and where it leaks.
- We confirm whether the roof is suitable for electronic testing.
- We pick the low-voltage or high-voltage method that suits the roof.
- The roof is tested and any breaches are located.
- The breaches are recorded with photographs in a report for your roofer.
How to prepare
- If you’re buying, let the agent know when we are coming
- Leave a clear route to the loft
- If the roof is shared, arrange access with whoever manages the building
