Electronic leak detection in Farnborough, Greater London
Not sure what state the flat roof membrane is in? We carry out electronic leak detection in Farnborough and across Greater London.
- New membranes needing a check before handover
- Leaks showing away from the breach
- Leaks that return after repairs
What we do, step by step
We do not take risks to get a closer look. We inspect whatever is safely visible, and if part of the roof cannot be seen, the report says so. The survey typically takes longer on a large roof than a small one, with the construction of the roof playing a part too. For a visit in Farnborough, parking and access are the things to plan: let us know about parking, the floor the property is on, any shared entrance and loft access. We then look at whatever is safely visible from ground level, windows, the loft and, where it is safe, the roof itself.
- 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.
- The testing method is chosen to suit the membrane and build-up.
- Testing runs across the roof to locate breaches in the membrane.
- The breaches are recorded with photos in a report for your roofer.
How to prepare
- If you are buying, check with the agent that we can get in
- Let us know about parking before the day
- Keep pets in another room
Booking a survey
A quick phone call is typically the easiest start: ring 07833 053749 or email us, and we’ll ask about the building and what you need. You will have a price before anything is arranged.

Electronic leak detection in Farnborough
Water can travel under a flat roof membrane before it shows inside. That makes leaks hard to trace by eye. Electronic leak detection tests the membrane itself, to find where it has been breached. It’s testing only, and the repair is for your roofer. On suitable roofs, it replaces guesswork with a located breach. The results then follow in a written report with photos. Typical surveys look at leaks through a covered membrane and holes left by work on the roof, across flat roof membranes, single-ply roofs and liquid-applied waterproofing.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a block or conversion in Farnborough, the flat roof is often a shared part of the building.
Every survey ends with a written report, with photographs, emailed to you. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

What affects the cost of electronic leak detection
We confirm the price for your survey before booking. These are the things that affect it:
- Chimneys, valleys, parapets and other details
- Building height and the viewpoints available
- How many separate roofs there are, such as extensions, dormers and garages
- If the survey needs thermal imaging or a drone
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You’ll know the price for the job before booking.
Getting in touch
There’s no need for technical words. It’s enough to tell us:
- Pictures from the garden or a window, if you have them
- What made you get in touch
- Anything about access we should know
- Your postcode, so we can check access and travel
We confirm the price for your survey before you book, so you know where you stand. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, phone 07833 053749 or email us.
Rented homes, blocks and businesses
Where a roof is shared: we need access agreed with the building owner or managing agent. Tell us about it when booking and we’ll plan the visit with that in mind.
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work with less disruption.
Common questions in Farnborough
Is parking a problem for a survey in Farnborough?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when booking.
How do I find out if my home in Farnborough is listed?
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.
Are you structural engineers?
No. We’re roof surveyors, not structural engineers. We will recommend an engineer if we see signs that call for one.
How much does electronic leak detection cost?
We quote for each roof individually. Let us know about the roof and where it leaks, and ring 07833 053749 or email us for a quote.
Do you survey on Saturdays and Sundays?
Visits run seven days a week in the daytime. Just say which days work for you.
Will you fly a drone over my roof?
Yes, where it is applicable. Flights depend on the weather on the day and airspace rules. We hold a CAA Flyer ID and Operator ID.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We look at the roof, not the whole building, so it’s not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
Flat and commercial roofs around Farnborough
The wider area around Farnborough has a long history of building, with Down House about 2.1 miles south-west. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Take an older house close to Church of St Giles the Abbot: the flat roofs on later extensions tend to wear out long before the main roof. Anyone responsible for a site like Farnborough Primary School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Other services in Farnborough
Do you need electronic leak detection in Farnborough?
Water travels under flat roof membranes. The leak may show some distance from where water gets in which makes it hard to find by looking.
A survey makes sense if you’ve noticed:
- Leaks through a covered membrane
- Leaks through a flat roof with no obvious cause
- Failed seams and laps
- Breaches around outlets and penetrations
Landlords with a home close to Orpington station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Questions to ask before booking
- Which viewpoints they use to see the roof
- Whether the price includes VAT
- Which limits apply to the survey
- How soon the report will arrive
What electronic leak detection does not cover
Every survey has limits, and we’d rather be clear about that before you book. Keep these in mind:
- Carrying out the repair work
- Water entering through details rather than the membrane
- Areas we can’t reach or that can’t be tested
If in doubt, phone 07833 053749 or send us an email and we’ll suggest the right survey. What our survey covers.
Roof types and parts we check
- Green roofs
- Roof terraces and balconies
- Commercial flat roofs
- Liquid-applied waterproofing
- Flat roof membranes
- Single-ply roofs
Tips that help
A survey works best with a little help from you, before and after. Tips:
- Use boards when working on the roof
- Keep outlets clear of debris
- Test new membranes before covering them
- Note where leaks show inside and when
If we think the leak is not coming through the membrane, the report says so, with a suggestion of what to check next.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.
