Electronic leak detection in Leverstock Green
You get a report showing the location of each breach with photos. It tells your roofer exactly where to repair instead of hunting for the leak. We do not estimate repair costs, so your roofer prices the work. Testing again after repairs can confirm the breaches have been dealt with if the build-up allows. You get a written report with photos. We survey green roofs, commercial flat roofs and flat roof membranes, and the problems we are asked to look at most are failed seams and laps and leaks through a flat roof with no obvious cause.
Around a smaller place like Leverstock Green, flat roofs normally cover extensions, garages and dormers. They’re small, but a leak over a kitchen extension can do a lot of harm. What it’s covered in, and how well it was laid, decides what it needs, from felt and asphalt to EPDM rubber and GRP. Ponding, splits and lifting edges are the signs to look for from a window.
Pictures do a lot of the work in our reports, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

What we cannot see
A survey is a proper look at the flat roof membrane, but it cannot do everything. The main limits are:
- Parts of the roof covered by fixed equipment
- Leaks from walls, copings or rooflights
- Moisture spread under the membrane

- Flat roof membranes
- Commercial flat roofs
- Single-ply roofs
- Green roofs
- Roof terraces and balconies
- Liquid-applied waterproofing
What we do, step by step
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. All told, expect a time that depends on the roof’s area and construction, which we’ll explain when we quote. With a bit of garden around a house, as there often is around Leverstock Green, the roof can be viewed from several angles. Let us know if any side is fenced off or hard to reach. The loft, where there’s safe access, completes the picture.
- We agree the area to be tested.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Before the survey
- Mention any parking restrictions on your street
- If it isn’t your property yet, arrange access through the agent
- Note where any stains or damp appear
Arrange a survey
If you’re buying, it is useful to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just ring 07833 053749 or use the contact form when you are ready.
Advice
Tips that help
A survey works best with a little help from you, before and after. Tips:
- Do not leave water getting in
- Note where leaks show inside and when
- Avoid repeated repairs without finding the cause
- Limit access to the roof
If water has been getting in, insulation under the membrane may be wet. That is something to discuss with your roofer, and moisture readings can help.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.
FAQs for Leverstock Green
Will you come out to Leverstock Green?
Yes, we do. Our area covers London and the South East, from towns to the smallest villages. Longer journeys are simply planned beforehand.
How do I find out if my home in Leverstock Green is listed?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it is worth checking before planning any.
How experienced are you?
We have more than 20 years’ experience and have completed over 5,000 surveys.
Does ELD work under paving or planting?
In some cases. It depends on the build-up and the layers above the membrane, and some may need lifting. We’ll discuss it before we quote.
How do I book a survey in Leverstock Green?
It’s easiest to ring 07833 053749 or use the contact form. Let us know the address and a little about the roof. Surveys run seven days a week.
Will you photograph what you find?
Yes, every report has them. Each finding is shown in a picture where possible.
Do I have to be there for the survey?
Not necessarily. An outside-only look can be arranged beforehand, but anything inside needs someone there to give access.
What happens if roof problems are left?
Not every leak is in the membrane. ELD helps rule the membrane in or out, so other causes can be checked. Around Leverstock Green, leaves and moss in gutters lead to overflowing water and damp walls. Dealing with the cause is simple; drying out a wall is not.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Why us?
- 20+ years’ experience
- Satisfaction rate of 98%
- Independent findings on the roof’s condition
- Photographs and a written report every time

Electronic leak detection in Leverstock Green: local notes
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, and flat-roofed additions turn up almost everywhere. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Historic houses like Batchwood Hall, about 3.5 miles east, show how far back building in the area around Leverstock Green goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area.
If you run a business near Village Arcade St Albans, the flat roofs over shops and commercial units are worth checking before a leak, not after. For landlords with property near Apsley station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

Holes in a membrane frequently come from feet, tools or debris. Some are too small to see, but still let water through.
People normally book a survey after spotting something like this:
- Water coming in under a flat roof
