How electronic leak detection works in Grange Park
Green roofs, ballasted roofs and roofs under paving are harder to test. The layers on top can limit the methods we can use, and some may need lifting. We talk this through before we quote. Any details of the build-up help, as they show what lies beneath the surface. We will tell you if the roof can’t be tested. If you’ve noticed leaks that return after repairs and leaks showing away from the breach, a survey will tell you what’s going on, on roof terraces and balconies, flat roof membranes and green roofs alike.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in Grange Park, the roof above may belong to the building rather than one flat.
Findings are set out part by part, from the coverings down to the gutters, each with a short note and a photo. You’ll see the good as well as the bad.

What else we do in Grange Park
Local flat roofs in Grange Park
Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. About 2 miles north-east lies Forty Hall, a reminder of how long the area around Grange Park has been built on. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material.
For landlords with property near Grange Park station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. Grange Park is in London, so parking needs planning: a visitor permit or a nearby bay makes the day easier, as a space near the door cannot be promised.

Different roofs, different checks
EPDM rubber roofs
Some EPDM membranes conduct electricity, which can rule out some methods. We will say if the test will not work.
Single-ply membranes
Punctures from foot traffic and equipment are common on single-ply roofs. Testing helps find them.

With a portfolio of properties, surveys can be booked for more than one address. To discuss a number of properties, call 07833 053749 or email us.

Common questions in Grange Park
Do you cover Grange Park?
Yes, Grange Park is within the area we cover. We cover the whole of London and South East England. Just ring 07833 053749 or email us and let us know about the property, and we will talk through which survey suits.
Is my home in Grange Park listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
What’s in the report?
You get our findings in writing, part by part, with photos, finishing with recommendations. The most urgent items are made clear.
Can you test a green or ballasted roof?
On some roofs, yes. What sits on the membrane affects the method, so we check the build-up first.
What happens next?
You receive the written report by email, with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
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.
How fast do 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.
What we do, step by step
When we arrive, we begin with a quick chat about the roof and anything that’s worrying you. After that, we check everything we can see safely. The survey typically takes a time that depends on the membrane area and the build-up, and we’ll give you a guide when quoting. From the street, a London terrace usually shows only its front slope or parapet, so in Grange Park 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? Tell us who holds the keys.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Before the survey
- Have keys ready for side gates, garages or roof access doors
- Agree roof access with the managing agent if it’s shared
- If you’re buying, let the agent know when we’re coming

A survey makes sense if you’ve noticed:
- Water coming in under a flat roof
- Leaks at pipes, outlets or fixings
- Gaps at membrane joints
- Damp inside with no sign on the roof
If you run a business near Edmonton Green Shopping Centre, a flat roof over a business is out of sight and out of mind until it leaks.

- Is there a chance to talk the report through?
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Whether VAT is in the quoted price
