Stonebridge Park Electronic Leak Detection
Electronic leak detection in Stonebridge Park from an independent, experienced roof surveyor. More than 20 years and over 5,000 surveys.
- Gaps at membrane joints
- Leaks under green or ballasted roofs
- A flat roof leak that cannot be traced
Practical tips
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Some tips:
- Check trades protect the waterproofing
- Consider ELD before paving or planting goes on
- Limit access to the roof
- Tell us about the membrane and build-up if you know it
If anything in the report isn’t clear, ask us. We can talk you through the findings.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.
About our electronic leak detection in Stonebridge Park
Not every flat roof suits electronic testing. Some membranes conduct electricity themselves, and some build-ups lack the layer the test needs below the membrane. We will say if ELD will not work on your roof at the start. Any details you have about the membrane and build-up help us decide, such as drawings or specifications. It avoids arranging a test that can’t give results. If you’ve noticed water coming in under a flat roof and damage from equipment installers, we can find out what’s behind it.
On a London roof terrace or a flat roof over a back addition, water often runs under the covering before it shows. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a converted house in Stonebridge Park, the roof above may belong to the building rather than one flat.
We keep jargon out of it: if work is needed, the report says so clearly, and where it can wait, that’s said too.

What affects the price in Stonebridge Park
The price reflects the time and kit the roof needs. The main factors are:
- The height of the building and how the roof can be seen safely
- House, block, shop or office
- How big the roof is
- How complicated the roof is, with its valleys, chimneys and parapets
The cost of a survey depends on the roof: 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.
What to let us know when you contact us
A little information up front helps. Please include:
- The property’s address and postcode
- What kind of property and roof it is
- How the loft is reached, if there is one
- Pictures of the roof from a safe spot, if you have them
Getting a price is simple: just call 07833 053749 or use the contact form, let us know about the property and we will explain which survey suits. We confirm the price before anything is booked.
How it works
When we arrive, we start by asking what you’ve noticed and what you need to know. We then inspect everything that can be seen safely, from ground level, from windows, in the roof space and by drone where it applies. Most surveys take longer on a large roof than a small one, and the build-up of the roof makes a difference too. In a London conversion, the way into the loft space is frequently from a communal landing or the top flat. Where that’s the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- 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.
- The report is sent for your roofer to act on.
Getting ready for the survey
- Tell us about any leaks, stains or damp patches you know of
- If it is not your property yet, arrange access through the agent
- Make a note of anything you’d like us to look at
How to book
We survey roofs seven days a week. To arrange a day that suits you, phone 07833 053749 or drop us an email.

Electronic leak detection in Stonebridge Park: local notes
Stonebridge Park has a number of hotels within about a mile and a half. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use. Historic houses such as Pitzhanger Manor, about 2.8 miles south-west, show how far back building in the area around Stonebridge Park goes. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first.
Take an older house close to St Michael the Archangel: any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. If you run a business near London Designer Outlet, flat roofs over shops and units are easy to forget until water comes through a ceiling.

FAQs for Stonebridge Park
Can you look at the flat roof of a hotel or office near Stonebridge Park?
Yes, we cover commercial roofs as well as homes. Roof access is agreed with the building manager or owner beforehand.
Is my home in Stonebridge Park listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
How does ELD work?
A sound membrane blocks the test current, so wherever there is a hole, it passes through. That is how we locate breaches you can’t see.
Do you survey roofs on blocks of flats?
Yes. Shared roofs just need a little more planning, with whoever owns or manages the building. Mention it when you get in touch and we’ll explain what’s needed.
Is the repair part of the test?
No, our part is finding the breaches. The report gives your roofer the locations.
Does the report include photographs?
Yes. We photograph the roof as we go, and they go into the written report alongside our recommendations.
How long have you been surveying roofs?
We have more than 20 years’ experience and have carried out more than 5,000 surveys across London and South East England.
Common roof problems in Stonebridge Park
Water travels under flat roof membranes. The stain inside can be far from the hole which makes it hard to find by looking.
Here are some of the things we see often:
- Patched roofs that still leak
- Gaps at membrane joints
- Waterproofing to test before it’s covered
- Leaks under green or ballasted roofs
A roof leak in a hotel or guest house around Stonebridge Park means lost rooms as well as repairs, so it is worth knowing the roof’s condition.
