How electronic leak detection works in Wallington
Electronic testing locates holes in the waterproofing, not every cause of water getting in. Leaks from walls, copings, rooflights or pipes need other checks. If the evidence points elsewhere, we will say so. It won’t show water getting in through brickwork or around frames. The report makes clear what was and wasn’t tested. We will point you to the likely next step. If you’re worried about stains far from any visible defect and leaks at pipes, outlets or fixings, a survey will tell you what’s going on, whatever the roof.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Each pipe, upstand and fixing through the covering is a possible weak point. For a building in Wallington, access is agreed with whoever manages the roof ahead of the visit. Plant bases, rooflights and cable entries are all places where water can get in.
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, for instance when you want to check whether anything has changed.

Local flat roofs in Wallington
With Nonsuch Mansion about 3.4 miles west, Wallington sits in an area with a long building history. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. 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 is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
Landlords with a home close to Wallington station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak. Wallington is in London, so parking needs planning: a visitor permit or a nearby bay makes the day easier, as a space near the door can’t be promised. If you look after a building such as Holy Trinity CofE Junior School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

How it works
Every visit follows the same pattern: we hear what you’ve seen, inspect the roof from each safe vantage point, take photos as we go and make notes for the report. Most visits take longer on a large roof than a small one, and the build-up of the roof makes a difference too. In a London conversion, the way into the loft space is frequently from a communal landing or the top flat. Where that’s the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Wallington runs like any other.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photos shows where each breach is.
Before we arrive
- Check pets are kept safely away
- Check we can get to the back of the property
- Clear the way to the loft hatch
Book a survey
Every survey is priced before it’s booked, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. For a price for your roof, phone 07833 053749 or drop us an email.
Advice
What happens if roof problems are left?
ELD before paving, ballast or planting goes on is simpler. Covered roofs are harder to test. In Wallington, as across London, an overflowing gutter soaks the wall below. 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 they’re priced to match. You will know the figure before booking.

Different roofs, different checks
Single-ply membranes
Single-ply can be punctured by tools or fixings. ELD can locate them.
EPDM rubber roofs
Certain rubber membranes are conductive which can limit electronic testing. We will tell you if yours is not suitable.
Tips from our surveys
Here are a few things we’d tell any owner:
- Tell us about the membrane and build-up if you know it
- Limit access to the roof
- Clear flat roof outlets regularly
- Get leaks traced quickly
The report records each breach location with photos. Pass it to your roofer to repair the breach points.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.

No. We are roof surveyors, not structural engineers, and it doesn’t include calculations. If we see signs that need an engineer’s opinion, we’ll recommend one.
