Electronic leak detection in Wapping: what you get
Green roofs, ballasted roofs and roofs under paving are harder to test. The layers on top can limit the methods we can use, and some may need lifting. We will discuss it with you when we quote. Drawings or details of the roof’s layers are useful, as they show what lies beneath the surface. If testing is not possible, we will say so. We survey green roofs, roof terraces and balconies and single-ply roofs, and people most frequently book us about breaches hidden under paving or planting and holes around roof penetrations.
On a London roof terrace or a flat roof over a back addition, water frequently runs under the covering before it shows. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a block or conversion in Wapping, the flat roof is often a shared part of the building.
Every survey ends with a written report, with photographs, emailed to you. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

Why act early in Wapping
Repeated call-outs for the same leak add up. A report showing the breach points gives your roofer a clear target. 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 often older than it looks.
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You’ll know the price for your survey before booking.
Why book with us
- Independent findings on the roof’s condition
- Every finding written up with photos

Wapping: your questions answered
Can you look at the flat roof of a hotel or office near Wapping?
Yes, commercial buildings, hotels included, are part of the work. Access to the roof is sorted out with whoever manages the building before the day.
Can parking be tricky for a visit in Wapping?
London parking needs a little planning, so let us know about permits, bays or a driveway when booking. That way the visit can be planned around it.
How long will testing take?
It typically takes a length of time set by the size of the roof and how it’s built, and we’ll give you a guide when quoting.
How do you choose the testing method?
We choose the method that suits the roof. You will know which method we plan to use before we start.
Does this replace a RICS home survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof and can sit alongside a RICS survey.
Will you go up on the roof?
Only where it is safe to do so. We check everything that can safely be seen: from ground level, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where it applies. Anything we can’t see is noted in the report.
How experienced are you?
We have more than 20 years’ experience and have carried out more than 5,000 surveys.

The survey, step by step
We work from the outside in: outside views come first, then the loft space if there is safe access. All told, expect a time that depends on the roof’s area and construction, which we’ll explain when we quote. In a London conversion, the way into the loft space is often from a communal landing or the top flat. Where that is the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Wapping runs like any other.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Preparing for the visit
- Keep pets in another room
- Have any questions written down, so nothing gets missed
- Let us know about any leaks, stains or damp patches you know of

Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, call 07833 053749 or email us with the address and the days you’d prefer.

Electronic leak detection in Wapping: local notes
About 1.3 miles west lies Mansion House, a reminder of how long the area around Wapping 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, and the council can say whether a home is in a conservation area. Many homes in inner London are Victorian and Edwardian terraces, often with Welsh slate roofs. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. If your home in Wapping is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Hotels and guest houses near Wapping can’t easily close rooms for a leak, so it is worth knowing the roof’s condition. Anyone responsible for a site like St Mellitus College will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. Landlords with a home close to Wapping station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Tips that help
These tips come from what we see on roofs every week, before and after a survey:
- Make sure trades protect the waterproofing
- Consider ELD before paving or planting goes on
- Share any drawings of the roof
- Keep a note of leaks after rain
File the report with your roof paperwork. It shows the condition of the membrane on that date.
Ask trades working on the roof to protect the membrane when they work up there. Check the roof after they’ve finished.
Honest limits
It’s a careful look at the flat roof membrane, not the whole story. The main limits are:
- Water entering through details rather than the membrane
- The extent of water in the insulation
- Build-ups without a suitable layer below

How the survey changes by roof type
Bituminous membranes
Bitumen roofs can frequently be tested electronically, depending on what’s below.
EPDM rubber roofs
Some EPDM membranes conduct electricity which can limit electronic testing. We will say if the test won’t work.
