How electronic leak detection works in Gadshill
ELD finds breaches in the membrane but not every way water gets 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. The test shows breaches in the membrane, not water coming through masonry or around frames. The report makes clear what was and wasn’t tested. We’ll point you to the likely next step. We are often asked to look into failed seams and laps and stains far from any visible defect, across green roofs, commercial flat roofs and flat roof membranes.
In a small place like Gadshill, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Felt roofs, which often 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 works through the roof section by section, from the main slopes down to the gutters and outlets. You will see the good as well as the bad.

What affects the cost of electronic leak detection
What a survey costs depends on the time and equipment it needs. That comes down to:
- The height of the building and how the roof can be seen safely
- The size of the roof
- How complicated the roof is, with its valleys, chimneys and parapets
- Whether thermal imaging or a drone is needed
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before booking.
Helping us price your survey
Getting the details right at the start saves time. It’s useful to include:
- The reason for the survey, such as buying, a leak or storm damage
- Your timetable, such as an exchange date
- The style of property, from a terrace to a block
- Where the property is, with the postcode
To arrange a survey, call 07833 053749 or drop us an email and let us know the address and what’s prompted the survey. We will confirm the price before you book.
Why act early in Gadshill
Cutting open a flat roof to find a leak can cause more damage. ELD aims to locate the breach first so your roofer knows where to work. For an older or listed building in a place like Gadshill, repairs may need matching materials and consent, so leaving a defect until it’s urgent leaves less time to plan.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.

How it works
Every roof is different; as a rough guide, the survey takes as long as needed for the size of the roof and how it’s built, which we’ll explain when we quote. You are welcome to ask questions while we’re there. Around Gadshill, older homes can have small or awkward roof spaces, so tell us about the loft hatch and any ladder. We only go where it’s safe.
- First, you let us know about the roof build-up and where water is showing.
- We check that the membrane and build-up suit electronic leak detection.
- We pick the low-voltage or high-voltage method that suits the roof.
- We test the membrane and find where current is passing through it.
- You get a report showing where each breach is, for your roofer to repair.
Preparing for the visit
- Tell us about any leaks, stains or damp patches you know of
- Let us know about parking before the day
- Make sure the loft hatch can be reached
Arrange a survey
If you’re buying, it helps to book soon after your offer is accepted, so there is time to use the report before exchange. For any other survey, just call 07833 053749 or send us an email when you are ready.

Practical tips
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Tips:
- Note where leaks show inside and when
- Keep outlets clear of debris
- Get leaks traced quickly
- Avoid repeated repairs without finding the cause
Questions about the results are welcome. We can talk you through the findings.
Keep outlets and gutters on flat roofs clear. Standing water puts more pressure on any weak point.
What we’re asked to look at in Gadshill
Seams are a common weak point in flat roof waterproofing. Small openings at laps can leak long before anyone notices.
Signs worth acting on include:
- Leaks at pipes, outlets or fixings
- Failed seams and laps
- Holes left by work on the roof
- Leaks through a flat roof with no obvious cause
If you own a rental within reach of Higham station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
What to check before booking
- Is VAT included in the price?
- Their track record with similar roofs
- Whether the loft space is looked at, where there is one
- Whether you can ask questions once you have the report
When you need someone else
It helps to know what a survey won’t do before you book:
- Moisture spread under the membrane
- Parts of the roof covered by fixed equipment
- Roofs whose membrane or build-up isn’t suitable
If you’re not sure which survey you need, call 07833 053749 or email us and we’ll give you a straight answer before booking. The full list of what we check.

Questions from Gadshill
Does being near the coast affect roofs in Gadshill?
Yes, coastal weather is harder on roofs: there’s more wind, and more salt in the air. Ridges, verges, flashings and fixings are where it normally shows, and Gadshill is within about 4 miles of the coast.
Is my home in Gadshill listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a 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.
Does someone need to be in?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you as you book.
Do you use drones?
Yes, where it’s applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.
What does the report include?
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, so you know exactly what was covered.
Is the repair part of the test?
No. We test the membrane and report. The report shows where each breach is for your roofer to repair.
Can you test a green or ballasted roof?
Sometimes. The layers on top and the build-up below decide it and parts may need to be lifted. We’ll discuss it before we quote.
What electronic leak detection looks like in Gadshill
Gadshill is within about 4 miles of the coast, where sea air brings more salt and stronger wind than inland. On a flat roof near the sea, edge trims and upstands take the brunt of the wind, and metal parts corrode faster. About 1.9 miles south-east lies Temple Manor, a reminder of how long the area around Gadshill has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area.
Anyone responsible for a site like Strood Academy will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If you run a business near Pentagon Shopping Centre, a flat roof over a business is out of sight and out of mind until it leaks.
