About our electronic leak detection in South Ruislip
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It helps trace a leak you already have or to test a new membrane before it’s covered. Each roof is quoted on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays when conditions allow. Just ask about your roof. If you’re worried about damp inside with no sign on the roof and repairs that haven’t stopped the leak, a survey will tell you what’s going on.
Offices, shops and blocks of flats across London often have large flat roofs with plant, rooflights and walkways. Each pipe, upstand and fixing through the covering is a possible weak point. In South Ruislip, 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.
We write the report in plain English, so you don’t need to be a roofer to follow it. Photographs show what each point refers to, with the urgent items made clear.

Leave it or get it looked at?
A visual inspection can miss tiny holes. Electronic testing can find breaches you cannot see by eye where the roof suits it. 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.
To find out what your survey will cost, phone 07833 053749 or send us an email with the address and some details. We will confirm the figure before booking.

Rented homes, blocks and businesses
We survey roofs for landlords and letting agents as well as householders. The report gives you a dated record of the flat roof membrane, with photos.
Managing agents and residents’ management companies use roof surveys to plan maintenance. The report sets out what needs attention now and what can wait, which helps with budgets and planning.
What a survey costs
What a survey costs depends on the time and equipment it needs. That comes down to:
- The height of the building and how the roof can be seen safely
- Extensions, dormers and garages with roofs of their own
- Features like valleys, chimneys, dormers and parapets
- House, block, shop or office
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.
Booking your survey
A little information up front helps. It is useful to include:
- The property’s address and postcode
- Pictures from the garden or a window, if you have them
- Your timetable, such as an exchange date
- What’s prompted the survey
Our phone lines are open seven days a week. To book or ask a question, call 07833 053749 or use the contact form.
How the survey changes by roof type
Single-ply membranes
Many offices and units have single-ply roofs. Seams and penetrations are typical breach points.
Inverted and paved roofs
A terrace or paved roof hides the waterproofing. Whether it can be tested depends on the build-up.
Electronic leak detection in South Ruislip: local notes
The wider area around South Ruislip has a long history of building, with Northolt Manor about 1.4 miles south-east. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops.
For a London address like South Ruislip, it is useful to know about controlled parking before the day, along with any off-street space. If you live in an older home near Church of St Mary, the joins between later flat roofs and the old walls are where problems normally start. Shop and office owners around St. George's Shopping Centre may find that a flat roof over a business is out of sight and out of mind until it leaks.

Questions from South Ruislip
Is South Ruislip in the area you cover?
Yes, South Ruislip is within the area we cover. Our area covers London and South East England. Just phone 07833 053749 or drop us an email and tell us about the property.
Will parking be an issue for a roof survey in South Ruislip?
It depends on the street. If South Ruislip has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
What happens after the survey?
You receive the written report by email, with photos and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Will you go up on the roof?
Only when it’s safe. Most of what we need can be seen from safe viewpoints, the loft and, where applicable, a drone.
How does ELD work?
ELD passes a small electrical current across the roof to locate holes in the membrane. A breach lets the current through so we can pinpoint it.
Does someone need to be in?
Not necessarily. If we only need the outside, we can agree that ahead of time, but anything inside needs someone there to give access.
How fast do I get the report?
That depends on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. Reports are sent by email.
What we can’t see
In fairness, there are limits to any roof survey:
- Repairing the breaches (that’s for your roofer)
- Some conductive membranes
- The extent of water in the insulation
If in doubt, phone 07833 053749 or drop us an email and we’ll point you to the right survey before you book. The full list of what we check.

The survey, step by step
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. All told, expect as long as needed for the membrane area and the build-up, and we’ll give you a guide when quoting. For a visit in South Ruislip, parking and access are the things to plan: let us know about parking, the floor the property is on, any shared entrance and loft access. We then look at what can safely be seen from the ground, windows, the loft and, where it is safe, the roof itself.
- We agree the area to be tested.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Before we arrive
- Jot down any questions you want answered
- Tell us where we can park nearby
