Electronic leak detection for homes and businesses in Cold Harbour
We carry out electronic leak detection on flat roofs in Cold Harbour and across London and South East England. A visit usually takes as long as needed for the roof’s area and construction, and we’ll give you a guide when quoting. Every roof is quoted on its size and build-up. The results come in a written report with photos. We survey flat roof membranes, single-ply roofs and green roofs, and common reasons people get in touch are leaks under green or ballasted roofs and holes left by work on the roof.
In a village or hamlet like Cold Harbour, flat roofs are usually on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access in advance. If there are outbuildings or garages with flat roofs, mention them as you book.
Where we can’t see part of the flat roof membrane, the report says so. You’ll know exactly what was inspected and what wasn’t.

Rented homes, blocks and businesses
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait, which helps when budgeting.
Where a roof is shared: we need access agreed with the freeholder or managing agent. Tell us about it when you book and we’ll plan the visit with that in mind.
Electronic leak detection around Cold Harbour
With Harleyford Manor about 3.3 miles north, Cold Harbour sits in an area with a long building history. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops.
If your house is among the older ones in the streets near Saint Peter, the joins between later flat roofs and the old walls are where problems normally start. Anyone responsible for a site like Knowl Hill Church of England Primary Academy will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. For landlords with property near Wargrave station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

Leave it or get it looked at?
Repairs in the wrong place leave the leak in place. Testing shows where the membrane is actually breached. For an older or listed building in a place like Cold Harbour, repairs may need matching materials and consent, so a defect found early gives time to plan the work properly.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before you book.
Why book with us

- Two decades and more of roof surveys

- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.

Common questions in Cold Harbour
Will you come out to Cold Harbour?
Yes, Cold Harbour is on our map. A small place gets exactly the same survey as a big one.
Do you cover Cold Harbour?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
How soon will I get the report?
It depends on the package: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. Reports are sent by email.
How does ELD work?
It uses an electrical current to find breaches in a flat roof membrane. A breach lets the current through so we can pinpoint it.
What’s the price of ELD?
We quote for each roof individually. Tell us about the roof and where it leaks, and phone 07833 053749 or drop us an email for a quote.
What happens after the survey?
The report comes by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
How long does electronic leak detection take?
Testing typically takes as long as needed for the size of the roof and how it’s built, and we’ll give you a guide when quoting.
How the survey changes by roof type
Bituminous membranes
Older felt roofs frequently have seams and patches that can leak. Testing depends on the roof.
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Some methods can work through these layers, depending on the build-up.
Before and after the survey
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Note where leaks show inside and when
- Tell us about the membrane and build-up if you know it
- Make sure trades protect the waterproofing
- Find the breach before more patching
If water has been getting in, insulation under the membrane may be wet. That’s something to discuss with your roofer and other checks can help judge it.
Consider testing a new membrane before it’s covered. Finding breaches is simpler at that stage.
What a survey costs
We confirm the price for the job before booking. These are the things that affect it:
- The roof’s overall size
- The height of the building and how the roof can safely be seen
- Whether thermal imaging or a drone is needed
- How complicated the roof is, with its valleys, chimneys and parapets
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You’ll know the price for your survey before booking.
Booking your survey
Some details help us suggest the right survey and price. When you get in touch, it is useful to mention:
- Pictures from the garden or a window, if you have them
- How the loft is reached, if there is one
- What kind of property and roof it is
- The property’s address and postcode
A quick phone call is typically the easiest start: phone 07833 053749 or use the contact form and we will ask a few questions about the roof. You’ll have a price before anything is arranged.
