About our electronic leak detection in Hampstead Garden Suburb
Electronic leak detection works on many flat roof membranes over offices, units, blocks of flats and homes. It helps trace a leak you already have or to test a new membrane before it’s covered. Each roof is quoted on its size and build-up. We can test on weekdays and at weekends when conditions allow. Tell us about your roof to find out more. We survey commercial flat roofs, roof terraces and balconies and green roofs, and the problems we’re asked to look at most are leaks that return after repairs and leaks at pipes, outlets or fixings.
Offices, shops and blocks of flats across London frequently have large flat roofs with plant, rooflights and walkways. Every penetration and upstand is a place where a membrane can fail. In Hampstead Garden Suburb, roof access is agreed with the building manager or owner beforehand. Plant bases, rooflights and cable entries are all places where water can get in.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

Signs you need electronic leak detection in Hampstead Garden Suburb
Water travels under flat roof membranes. The stain inside can be far from the hole, so tracing it by eye is difficult.
We’re frequently asked to look at:
- Water coming in under a flat roof
- Leaks through a covered membrane
- Leaks that return after repairs
- Stains far from any visible defect
If you look after a shop, office or commercial unit, for instance near Brent Cross Shopping Centre, flat roofs over shops and units are easy to forget until water comes through a ceiling.
Questions to ask before booking
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- Whether you get a written report with photos
- Their insurance cover
- What happens after the report arrives
What happens if roof problems are left?
Some breaches are too small to see. ELD picks up breaches a visual check might miss, on suitable membranes. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. Knowing what’s needed early gives you time to plan it calmly.
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You’ll know the price for the job before booking.

Useful tips for Hampstead Garden Suburb property owners
From years of surveys, a few habits stand out as worth the effort:
- Act on new leaks promptly
- Find the breach before more patching
- Use boards when working on the roof
- Consider ELD before paving or planting goes on
File the report with your roof paperwork. It shows the condition of the membrane on that date.
Keep outlets and gutters on flat roofs clear. Standing water puts more pressure on any weak point.
What electronic leak detection doesn’t cover
No survey can tell you everything, and we’d rather be clear about that before you book. Bear these in mind:
- Water entering through details rather than the membrane
- Fixing the holes we find
- Areas we cannot reach or that cannot be tested
Not sure which survey suits your roof? You can phone 07833 053749 or email us and we will tell you. What a survey covers and does not.
What we look at
- Liquid-applied waterproofing
- Flat roof membranes
- Roof terraces and balconies
- Single-ply roofs
- Green roofs
- Commercial flat roofs
The survey, step by step
We will ask a few questions first, such as when any problem began and what work has been done before. Then the inspection itself takes a time that depends on the membrane area and the build-up, and we’ll give you a guide when quoting. London terraces rarely offer a view of the whole roof from one spot, so in Hampstead Garden Suburb 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.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Preparing for the visit
- Move anything stored under the loft hatch
- Let us know about any leaks, stains or damp patches you know of
- Tell us about parking before the day
