How electronic leak detection works in Falconwood
Electronic testing locates holes in the waterproofing but not every way water gets in. Leaks from walls, copings, rooflights or pipes need other checks. 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’ll also know what to check next. We survey green roofs, commercial flat roofs and flat roof membranes, and common reasons people get in touch are leaks that return after repairs and leaks at pipes, outlets or fixings.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, each with its own weak points. Which one is on a roof in Falconwood shapes how it’s checked. Older flat roofs are frequently felt or asphalt, newer ones rubber or GRP.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. You will know exactly what was inspected and what wasn’t, and what we’d suggest next.

FAQs for Falconwood
Do you cover Falconwood?
We do. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Is my home in Falconwood listed or in a conservation area?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
How long does electronic leak detection take?
The roof’s size and build-up decide how long it takes. You will know roughly how long before we start.
What happens after the survey?
We email you the written report with photographs and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Do you look in the loft space?
Where it is relevant to the survey and there’s safe access, yes. Please clear anything stored under the hatch, and if the loft can’t be reached safely, the report says so.
Will you fly a drone over my roof?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
How do I book a survey in Falconwood?
Simply phone 07833 053749 or use the contact form. After a few questions, we confirm the price and fix a day.
Flat and commercial roofs around Falconwood
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as 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. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. The wider area around Falconwood has a long history of building, with Danson House about 1 mile east. 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.
For site and facilities teams at buildings such as Bishop Ridley Church of England VA Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. The streets around a church like Bishop Ridley Church are often among the oldest in a place, and if yours is one of the older homes nearby, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
Falconwood is about 2 miles north-east of Eltham, in Greater London. Houses, flats, blocks and commercial buildings in Falconwood can all book electronic leak detection. We cover towns and villages across Greater London, from the larger towns to small villages. There is also a page for London.
Surveys in DA16, DA15 and SE9 are booked the same way as anywhere else. Local streets include Hook Lane, Gordon Road and Kent Avenue. Nearby, we also carry out electronic leak detection in Blackfen (1 mile south), East Wickham (1 mile north), Avery Hill (1 mile south-west), Shooter's Hill (1 mile north-west) and New Eltham (2 miles south-west). Larger places within reach include London (9 miles west), City of Westminster (11 miles west), Marylebone (11 miles west), Kensington (13 miles west), St Pancras (10 miles north-west) and Shoreditch (9 miles north-west).
What’s near Falconwood

Open spaces near Falconwood include The Tarn and Summer Hill.
Before and after the survey
There’s plenty you can do without going near the roof. What helps most:
- Find the breach before more patching
- Use boards when working on the roof
- Limit access to the roof
- Keep a note of leaks after rain
Once repairs are made, the roof can be tested again if you want to check them, where the roof still suits the method.
Consider testing a new membrane before it’s covered. It’s easier to find holes before more layers are added.
Why get it checked now?
ELD before paving, ballast or planting goes on is simpler. Once layers are added, finding a breach is harder. In a London terrace or conversion, a roof defect rarely stays your problem alone: failed flashings and blocked valley gutters can send water into more than one home. Finding it early keeps the work smaller.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before you book.
Why book with us

How it works
You don’t need to do much on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll get on with the inspection. The survey itself 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 Falconwood 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.
- You tell us about the roof and where water is showing.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
Before the survey
- Unlock side gates and any roof access doors
- If you are buying, check with the agent that we can get in
- Clear the way to the loft hatch
Booking a survey
You can call us seven days a week, including Saturdays and Sundays. To book or ask a question, call 07833 053749 or drop us an email.

Common roof problems in Falconwood
Water travels under flat roof membranes. The stain inside can be far from the hole, so tracing it by eye is difficult.
People usually book a survey after spotting something like this:
- Leaks through a flat roof with no obvious cause
- New membranes needing a check before handover
- Leaks through a covered membrane
- Leaking laps in the waterproofing
As a London address, Falconwood can be tricky for parking: a visitor permit or a nearby bay makes the day easier.
Questions to ask before booking
- Will the report include photos?
- Whether the loft is part of the inspection
- Whether VAT is added on top
- What the survey will not cover
Different roofs, different checks
EPDM rubber roofs
ELD on EPDM depends on the product and the layers. We check this first.
Inverted and paved roofs
Paving and terraces cover the membrane. Suitability depends on the layers.

DIY checks: what’s safe
Your own check is a good start, but it isn’t a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
