Gibraltar Electronic Leak Detection

Electronic leak detection in Gibraltar: what you get
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It can be used to trace an existing leak or check a new membrane before handover. Each roof is quoted on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays when conditions allow. Let us know about your roof to find out more. We survey green roofs, liquid-applied waterproofing and roof terraces and balconies, and common reasons people get in touch are leaks through a flat roof with no obvious cause and damp inside with no sign on the roof.
Flat roofs on exposed homes in small places like Gibraltar take more wind and rain, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, normally show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are typically the first part of a flat roof to go.
The report works through the roof section by section, from the main slopes down to the gutters and outlets. It records what’s sound as well as what is not.

Gibraltar: your questions answered
Will you come out to Gibraltar?
Yes. Gibraltar is within the area we cover, which takes in towns, villages and rural addresses. We work right across London and the South East. Let us know about access, parking and anything unusual about getting there when booking.
Does a conservation area affect roof work in Gibraltar?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
How many surveys have you done?
We have been surveying roofs for over 20 years and have carried out more than 5,000 surveys.
How do you choose the testing method?
It depends on the membrane and the build-up. Low-voltage methods are normally carried out on a wet roof, while high-voltage testing needs a dry, exposed membrane.
Do you use drones?
Where it helps and it is safe, yes. Whether we can fly on the day depends on the weather and the airspace rules, and we check for restrictions near airports before flying. We’re a CAA-registered drone operator.
How does ELD work?
It uses an electrical current to find breaches in a flat roof membrane. The current only gets through where the membrane is breached so we can pinpoint it.
Do you need to get into the loft?
Where it’s relevant to the survey and there is safe access, yes. A clear path to the hatch helps.

How it works
Before we start, tell us why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. The visit typically takes a time that depends on the size of the roof and how it’s built, which we’ll explain when we quote. Older rural homes like those around Gibraltar can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints, and anything we cannot see is noted.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
How to prepare
- Let us know about parking near the property
- Let us know about any leaks, stains or damp patches you know of
- Leave side gates unlocked
Booking a survey
Most bookings start with a short call: phone 07833 053749 or email us and we’ll ask a few questions about the roof. You will have a price before anything is arranged.
Related advice
Why it’s worth a survey now in Gibraltar
A visual inspection can miss tiny holes. Electronic testing can find breaches you cannot see by eye where the roof suits it. Where a roof is exposed, as many are in small places like Gibraltar, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.
For a price for your roof in Gibraltar, ring 07833 053749 or email us and tell us about the roof. We’ll confirm the figure before booking.
Why book with us
- Professional indemnity and public liability insurance

Tips from our surveys
There’s plenty you can do without going near the roof. What helps most:
- Find the breach before more patching
- Let us know about the membrane and build-up if you know it
- Consider ELD before paving or planting goes on
- Act on new leaks promptly
If water has been getting in, insulation under the membrane may be wet. That is something to discuss with your roofer and other checks can help judge it.
Limit foot traffic on flat roofs. Many breaches come from foot traffic.
What we are asked to look at in Gibraltar
If a flat roof keeps leaking after patching, the hole may be elsewhere. ELD can locate the breach more precisely.
Signs worth acting on include:
- Holes left by work on the roof
- Waterproofing to test before it is covered
- Leaks under green or ballasted roofs
- Leaks showing away from the breach
If you let a flat or house near Haddenham & Thame Parkway station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Before booking any roof surveyor
- What the report includes, and whether it has photos
- How much experience they have with roofs like yours
- What follow-up you get after the report
- Whether the loft is part of the inspection
What affects the price in Gibraltar
Prices vary from roof to roof, and it comes down to:
- How tall the building is and how easy the roof is to see
- House, block, shop or office
- Whether thermal imaging or a drone is needed
- How big the roof is
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
Booking your survey
Here’s what helps us most when you contact us:
- How the loft is reached, if there is one
- Why you want a survey: buying, a leak, a storm or new work
- What kind of property and roof it is
- The address and postcode of the property
We confirm the price for your survey before you book, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. To book, phone 07833 053749 or send us an email.
Electronic leak detection in Gibraltar: local notes
Thatch survives on some older buildings in Buckinghamshire’s villages. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops. The wider area around Gibraltar has a long history of building, with Waddesdon Manor about 3.8 miles north-west. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area.
If yours is one of the older homes in the streets near Church of Saints Peter and Paul, the flat roofs on later extensions tend to wear out long before the main roof.
