Electronic leak detection for homes and businesses in Green Street Green
Electronic leak detection works on many flat roof membranes over offices, units, blocks of flats and homes. It can be used to trace an existing leak or to test a new membrane before it’s covered. Each roof is quoted on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays, depending on the weather. Let us know about your roof to find out more. We are often asked to look into damp inside with no sign on the roof and leaks under green or ballasted roofs, on liquid-applied waterproofing, commercial flat roofs and flat roof membranes.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Every penetration and upstand is a place where a membrane can fail. For a building in Green Street Green, access is agreed with whoever manages the roof ahead of the visit. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

What affects the price in Green Street Green
Not every roof costs the same to survey, for these reasons:
- Whether thermal imaging or a drone is needed
- Roof area
- Building height and the viewpoints available
- The number of roofs, including extensions and garages
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.

Tips that help
These tips come from what we see on roofs every week, before and after a survey:
- Clear flat roof outlets regularly
- Don’t leave water getting in
- Limit access to the roof
- Check new waterproofing before handover
If anything in the report isn’t clear, ask us. We can talk you through the findings.
Keep outlets and gutters on flat roofs clear. Standing water puts more pressure on any weak point.
Green Street Green questions
Is Green Street Green in the area you cover?
Yes. We cover the whole of London and South East England, and Green Street Green is part of that. You can call 07833 053749 or email us with the address and some details, and we’ll talk through which survey suits.
Can parking be tricky for a visit in Green Street Green?
It depends on the street. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well, and a driveway is even better.
Is this an asbestos survey?
No. We can flag materials that might contain asbestos, but only a specialist asbestos surveyor can confirm it. It may be present in buildings built or refurbished before 2000.
Are you insured?
Professional indemnity and public liability insurance cover our surveys. If you need details for a managing agent or a building owner, just ask.
How long have you been surveying roofs?
We have more than 20 years’ experience and have completed over 5,000 surveys.
Do you use drones?
Yes, where it’s applicable. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.
How soon will I get the report?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. All of them come by email, ready to forward.
The survey, step by step
There is not much for you to do on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we will take it from there. A typical survey takes a time that depends on the roof’s area and construction, which we set out in the quote. London terraces rarely offer a view of the whole roof from one spot, so in Green Street Green we work round the house, using the street, the windows, the loft and any safe vantage point behind it. Shared stairs or a basement flat? Let us know who holds the keys.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Preparing for the visit
- Note where any stains or damp appear
- Let us know about parking near the property
- Find any records of previous roof work

Advice
Electronic leak detection in Green Street Green: local notes
Historic houses such as Down House, about 2.1 miles south-west, show how far back building in the area around Green Street Green goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, frequently with hipped roofs in clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
For an older house near a landmark such as St Mary's Church, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. If you own a rental within reach of Chelsfield station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

When to book a survey in Green Street Green
Roofs covered with paving, ballast or planting hide the membrane. ELD can work on some covered roofs, depending on the build-up.
People typically book a survey after spotting one of these:
- Punctures from foot traffic or tools
- Patched roofs that still leak
- New roofs to check before paving or planting
- Damp inside with no sign on the roof
For a London address like Green Street Green, it helps to know about controlled parking before the day, along with any off-street space.
Before you book any roof surveyor
- What exactly goes into their report
- Is VAT included in the price?
- What they won’t be able to tell you
- Whether any drone flown is registered with the CAA
When you need someone else
Every survey has limits, and we’d rather be clear about that before booking. Bear these in mind:
- Leaks from walls, copings or rooflights
- Roofs whose membrane or build-up is not suitable
- Carrying out the repair work
