Electronic leak detection for homes and businesses in Widmore
Our ELD report shows where each breach was found, with photos. It tells your roofer exactly where to repair instead of hunting for the leak. We don’t estimate repair costs; that’s for your roofer to price. Testing again after repairs can confirm the breaches have been dealt with if the build-up allows. You get a photo-illustrated written report. We survey green roofs, flat roof membranes and roof terraces and balconies, and the problems we are asked to look at most are damp inside with no sign on the roof and breaches around outlets and penetrations.
Offices, shops and blocks of flats across London frequently have large flat roofs with plant, rooflights and walkways. Every penetration and upstand is a place where a membrane can fail. In Widmore, roof access is agreed with the building manager or owner beforehand. Plant bases, rooflights and cable entries are all places where water can get in.
Most points in the report come with a picture, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

Widmore questions
Do you cover Widmore?
Yes, Widmore is within the area we cover. We cover the whole of London and South East England. You can call 07833 053749 or drop us an email with the address and a few details, and we will talk through which survey suits.
Can parking be tricky for a visit in Widmore?
Parking in Widmore, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
What happens after the survey?
We email you the written report with photos and recommendations. It is yours to share with a seller, insurer, roofer or managing agent, whichever applies.
What’s the price of ELD?
We quote electronic leak detection for each roof, as the method and time depend on the roof. Size, build-up and access all affect the price. To get a quote, call 07833 053749 or drop us an email.
Can every flat roof be tested?
It depends on the membrane and the build-up. Share any details you have and we’ll confirm suitability.
Will you go up on the roof?
Not unless it’s safe. Safe viewpoints, the roof space and a drone where applicable cover most of what’s needed, and the report notes anything we couldn’t see.
How do you choose the testing method?
The roof decides the method. You will know which method we plan to use before we start.
How we price electronic leak detection
The price reflects the time and kit the roof needs. That comes down to:
- Features like valleys, chimneys, dormers and parapets
- How many separate roofs there are, such as extensions, dormers and garages
- The roof’s overall size
- Building height and the viewpoints available
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You’ll know the price for the job before booking.
What to tell us when you contact us
Some details help us suggest the right survey and price. When you contact us, let us know:
- What’s prompted the survey
- The kind of building and roof involved
- Any stains, drips or damp patches you’ve seen indoors
- Your timetable, such as an exchange date
Photos help, if you have them. Take them safely from ground level or a window. To send them or to book, call 07833 053749 or drop us an email.
What you can safely check yourself
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us when booking, as it helps us focus the survey.
Your own check is a good start, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground.
Practical tips
A survey works best with a little help from you, before and after. Tips:
- Use boards when working on the roof
- Act on new leaks promptly
- Note where leaks show inside and when
- Keep foot traffic on flat roofs to a minimum
If water has been getting in, insulation under the membrane may be wet. That’s something to discuss with your roofer and other checks can help judge it.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
Leave it or get it looked at?
Opening up a roof to hunt for a leak is disruptive. Electronic testing finds the hole first so your roofer knows where to work. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. When the stain finally shows, the damage underneath is frequently older than it looks.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Why book with us
- An independent view of the roof
- Drone flown under a CAA Flyer ID and Operator ID

Different roofs, different checks
Single-ply membranes
Single-ply can be punctured by tools or fixings. ELD can locate them.
Bituminous membranes
Older felt roofs often have seams and patches where breaches occur. Testing depends on the roof.
The survey, step by step
We don’t take risks to get a closer look. Everything that can be seen safely is inspected, and anything we can’t see is noted in the report. Most visits take more time on a big roof than a small one, with the construction of the roof playing a part too. London terraces rarely offer a view of the whole roof from one spot, so in Widmore 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, let us know who can let us into the shared parts.
- We agree the area to be tested.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Before we arrive
- Let us know about parking near the property
- Gather any invoices or paperwork from past roof work
- If you are buying, let the agent know when we are coming
Arrange a survey
You can call us seven days a week, including Saturdays and Sundays. For a price or to book, call 07833 053749 or drop us an email.

Flat roofs in Widmore
About 1.1 miles west lies Bromley Palace, a reminder of how long the area around Widmore has been built on. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof. Outer London has a good many Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. If your home in Widmore is one of them, bay roofs, hips and later dormers each have their own details. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
Controlled parking zones are common in London, so mention any permit rules for Widmore, along with any off-street space. If you let a flat or house near Bickley station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. For businesses in and around places like The Mall, the flat roofs over shops and commercial units are worth checking before a leak, not after.
