Electronic leak detection in Ruislip Gardens: what you get
We carry out electronic leak detection on flat roofs in Ruislip Gardens and across London and the South East. Testing normally takes a time that depends on the roof’s area and construction, which we’ll explain when we quote. Every roof is quoted on its size and build-up. You get a written report with photos. We survey flat roof membranes, roof terraces and balconies and green roofs, and people most frequently book us about leaking laps in the waterproofing and leaks at pipes, outlets or fixings.
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 block or conversion in Ruislip Gardens, the flat roof is often a shared part of the building.
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.

How it works
Photos are taken throughout the visit, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available. Most surveys take as long as needed for the roof’s area and construction, which we’ll explain when we quote. For a visit in Ruislip Gardens, parking and access are the things to plan: let us know about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. On the day, the roof is looked at from the ground, from windows, from inside the loft space and from the roof where it’s safe.
- 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.

Tips that help
Most of what helps is simple and safe from ground level. Our suggestions:
- Find the breach before more patching
- Get leaks traced quickly
- Stay off the flat roof unless needed
- Test new membranes before covering them
If we think the leak is not coming through the membrane, the report says so, with a suggestion of what to check next.
Check contractors protect the waterproofing when fitting equipment. Have the roof looked at after other work.
Questions from Ruislip Gardens
Do you carry out roof surveys in Ruislip Gardens?
We do. The survey and report are the same in Ruislip Gardens as anywhere else, and visits run on weekdays and weekends.
Will parking be an issue for a roof survey in Ruislip Gardens?
Usually it is manageable with a little notice. Tell us what parking is available nearby, and the visit is planned around it.
What does electronic leak detection do?
ELD passes a small electrical current across the roof to locate holes in the membrane. A breach lets the current through, which shows us where the hole is.
Do you need to get into the loft?
Typically, if there’s one and it can be reached safely. From inside, the underside of the roof frequently shows damp, staining or daylight that cannot be seen from outside.
Is my roof suitable for ELD?
That depends on the roof’s membrane and layers. Let us know what you know about the roof and we will check whether ELD will work.
Will you repair the leak?
No. We test the membrane and report. The report shows where each breach is so your roofer can fix them.
How much does electronic leak detection cost?
We quote for each roof individually. Send us details of the roof, and ring 07833 053749 or email us for a quote.
What electronic leak detection looks like in Ruislip Gardens
Historic houses like Ickenham Hall, about 1.3 miles west, show how far back building in the area around Ruislip Gardens 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. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Next to the main roofs there’s normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If you live in an older home near Church of St Paul, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. As a London address, Ruislip Gardens can be tricky for parking: a visitor permit or a nearby bay makes the day easier. Shop and office owners around The Chimes may find that flat roofs over shops and units are easy to forget until water comes through a ceiling.

Where a roof is shared: we need access agreed with the building owner or managing agent. Let us know about it as you book and we’ll plan the visit with that in mind.
What a survey costs
Prices always include VAT. What changes the price is:
- How many separate roofs there are, such as extensions, dormers and garages
- Whether it’s a home or a commercial building
- Any need for thermal images or a drone flight
- The height of the building and how the roof can safely be seen

Should I look at the roof myself first?
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way. That part is for a survey, using safe viewpoints and a drone where it applies.
Your own check is a good start, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground.
Leave it or get it looked at?
Water trapped under a membrane can soak insulation and decking. Locating it early helps limit the damage. Blocked gutters and hoppers on London houses overflow and soak brickwork, which can lead to damp inside. A blocked outlet ignored for a winter or two can mean damp walls inside.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You will know the figure before booking.
