Electronic leak detection for homes and businesses in Farnborough
Electronic testing locates holes in the waterproofing but not every way water gets in. Leaks from walls, copings, rooflights or pipes need other checks. We will 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. Our report keeps that distinction clear. We’ll point you to the likely next step. Common reasons to book are stains far from any visible defect and new membranes needing a check before handover, on commercial flat roofs, roof terraces and balconies and green roofs.
In a town like Farnborough, lots of shops, schools and business units have flat roofs. They’re easy to forget until water comes through a ceiling tile, and by then the insulation underneath may be wet. A survey, or electronic testing where the membrane suits it, shows what’s going on. If someone else manages the building, let us know so roof access can be arranged.
Findings are set out part by part, from the coverings down to the gutters. It records what’s sound as well as what is not.

Why it is worth a survey now in Farnborough
A visual inspection can miss tiny holes. ELD picks up breaches a visual check might miss, on suitable membranes. Around Farnborough, water from a roof defect often goes unseen for a while, soaking loft insulation, wall tops and timbers. By the time it shows inside, the job has grown.
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You will know the price for the job before you book.

Common roof problems in Farnborough
New membranes can have defects from installation. Testing before the roof is covered or handed over helps find them.
We’re often asked to look at:
- Breaches around outlets and penetrations
- A flat roof leak that can’t be traced
- New roofs to check before paving or planting
- Stains far from any visible defect
For an older house near a landmark like Church of St Christopher, the flat roofs on later extensions tend to wear out long before the main roof.
Questions to ask before you book
- Whether you get a written report with photos
- How soon the report will arrive
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Which limits apply to the survey
Tips that help
You do not need to be a roofer to help. Here’s what helps most:
- Note where leaks show inside and when
- Stay off the flat roof unless needed
- Clear flat roof outlets regularly
- Don’t leave water getting in
If we think the leak isn’t coming through the membrane, the report says so, so other causes can be checked.
Keep outlets and gutters on flat roofs clear. Standing water puts more pressure on any weak point.

Farnborough questions
Is my home in Farnborough listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
What do I need to do before a survey in Farnborough?
Clear the way to the loft hatch if there is one, and tell us about any leaks, stains or past repairs. Parking and access details for Farnborough help us plan the visit.
What’s in the survey report?
It works through the roof part by part, in writing and with photos, and ends with what we recommend. The most urgent items are made clear.
How quickly is the report sent?
That depends on the survey you book: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. The report is emailed to you.
Do you climb onto every roof?
Only where it’s safe to do so. We look at everything that can be seen safely: from ground level, from windows and vantage points, from the roof space, from the roof itself where safe and by drone where it applies. Anything we cannot see is noted in the report.
Can you test a green or ballasted roof?
Sometimes. It depends on the build-up and the layers above the membrane, and some may need lifting. We will discuss it before we quote.
Does ELD include fixing the breach?
No. ELD is testing only. The report shows where each breach is for your roofer to repair.
The survey, step by step
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. The inspection then takes a length of time set by the membrane area and the build-up, which we’ll explain when we quote. For a visit in Farnborough, we need access to the loft, any rooms with leaks or stains, and the outside of the building. If there’s a side gate or a rear garden, let us know how to reach it. Visits can be on weekdays, Saturdays or Sundays.
- We start by finding out what the roof is made of and where it leaks.
- The roof is assessed to see if electronic testing will work on it.
- 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.
- We send a report with photos of each breach so your roofer can repair it.
How to prepare
- Check the loft hatch can be reached
- Have any paperwork from past roof work to hand
- Tell us about any leaks, stains or damp patches you know of
Book a survey
You can call us seven days a week, including Saturdays and Sundays. To book or ask a question, ring 07833 053749 or use the contact form.

Flat and commercial roofs around Farnborough
A number of Hampshire villages keep thatched roofs on their older buildings. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Listing and conservation areas can both shape what roof work is allowed on an older home. The council is the place to check, along with Historic England’s list, before anyone quotes for re-roofing.
For businesses in and around places such as Hart Shopping Centre, a flat roof over a business is out of sight and out of mind until it leaks. If you let a flat or house near Farnborough Main station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
