How electronic leak detection works in Bickley
ELD finds breaches in the membrane but not every way water gets in. Water coming through walls, copings, rooflights or plumbing will not show on the test. We’ll tell you if we think the leak is coming from somewhere else. It won’t show water getting in through brickwork or around frames. The report makes clear what was and wasn’t tested. You will also know what to check next. We survey roof terraces and balconies, green roofs and single-ply roofs, and people most frequently book us about gaps at membrane joints and damp inside with no sign on the roof.
On a London roof terrace or a flat roof over a back addition, water often runs under the covering before it shows. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in Bickley, the roof above may belong to the building rather than one flat.
What you get is a clear record of the flat roof membrane on the day we saw it. That makes it useful now and a handy reference later, such as when you want to compare after future work.

What we are asked to look at in Bickley
Work on the roof can damage a membrane. Fixings, equipment and foot traffic can leave small holes.
Signs worth acting on include:
- Patched roofs that still leak
- Leaks at pipes, outlets or fixings
- Breaches hidden under paving or planting
- Failed seams and laps
If you run a business near The Mall, a flat roof over a business is out of sight and out of mind until it leaks.
Questions to ask before you book
- Is there a chance to talk the report through?
- What the survey will not cover
- Whether the roof space is looked at, where there is one
- Whether they hold professional indemnity and public liability insurance
Why it’s worth a survey now in Bickley
Some breaches are too small to see. ELD picks up breaches a visual check might miss, on suitable membranes. In Bickley, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Finding it early keeps the work smaller.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before you book.

Tips that help
A little preparation and a few simple habits help, both for the survey and for the roof itself. Some pointers:
- Avoid repeated repairs without finding the cause
- Check new waterproofing before handover
- Ask contractors to protect the membrane
- Note where leaks show inside and when
The report records each breach location with photos. Pass it to your roofer to repair the breach points.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.
Prices for electronic leak detection in Bickley
Every roof is different, so prices are confirmed before you book. These are the things that affect it:
- How tall the building is and how easy the roof is to see
- Whether thermal imaging or a drone is needed
- Extensions, dormers and garages with roofs of their own
- How complicated the roof is, with its valleys, chimneys and parapets
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You will know the price for your survey before booking.
What we need to know
Getting the details right at the start saves time. Please include:
- Any deadline, such as an exchange date
- The kind of building and roof involved
- The address and postcode of the property
- The reason for the survey, such as buying, a leak or storm damage

Bickley: your questions answered
Do you carry out roof surveys in Bickley?
We do. The survey and report are the same in Bickley as anywhere else.
Will parking be an issue for a roof survey in Bickley?
Parking in Bickley, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available as you book.
Is it a structural engineer’s report?
No. We note visible signs such as sagging or deflection, but we don’t carry out calculations or give an engineer’s opinion. If we think you need an engineer, the report says so.
Will you go up on the roof?
Not always. Some roofs are too steep or fragile to walk on safely. Safe viewpoints, the loft and a drone where it applies let us see the rest, and the report records anything we couldn’t see.
Do I have to be there for the survey?
That depends on the survey. For inside areas and the roof space, someone has to give us access, while outside access can be discussed as you book.
Can you survey at the weekend?
Surveys can be booked for any day of the week: weekdays, Saturdays and Sundays. Just tell us the days that suit you.
What’s the best way to book?
To book, call 07833 053749 or use the contact form with the address, the type of property and what’s prompted the survey. We will confirm the price and find a day that suits.

Electronic leak detection around Bickley
Historic houses like Bromley Palace, about 1.1 miles west, show how far back building in the area around Bickley goes. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If yours is one of the older homes in the streets near Church of St George, the joins between later flat roofs and the old walls are where problems typically start. If you look after a building such as Bullers Wood School for Boys, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

How the survey works
We check the roof from outside and, where it’s relevant and there’s safe access, from inside the loft space too. In the loft, the signs we look for are staining, damp, daylight and sagging. All in, the survey typically takes a time that depends on the membrane area and the build-up, which we set out in the quote. From the street, a London terrace normally shows only its front slope or parapet, so in Bickley we work round the house, using the street, the windows, the loft and any safe vantage point behind it. If other people live in the building, tell us who can let us into the shared parts.
- We agree the area to be tested.
- We get the roof ready for testing.
- Testing runs across the agreed area.
