Electronic leak detection in Avery Hill, Greater London
Electronic leak detection to pinpoint holes in flat roof membranes around Avery Hill, with a written report you can act on. Book a weekday or weekend visit.
- Leaking laps in the waterproofing
- Leaks that return after repairs
- Holes left by work on the roof
How it works
Photos are taken throughout the visit, so you can see in the report what we found and where. We take close-ups from wherever is safe, including by drone where it’s applicable and the weather allows. Most surveys take 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. In a London conversion, the way into the roof space is frequently from a communal landing or the top flat. If that applies to your building, it is useful to agree access with the neighbours or the managing agent first. Otherwise, the visit in Avery Hill runs like any other.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
How to prepare
- Show us where any leaks or stains appear
- Have any questions written down, so nothing gets missed
- For flats, make sure roof access has been agreed

Advice
About our electronic leak detection in Avery Hill
Some flat roofs cannot be tested electronically. Some membranes conduct electricity themselves and some roofs do not have a suitable layer beneath the membrane. We will say if ELD will not work on your roof before any testing. Any details you have about the membrane and build-up help us decide, like drawings or specifications. It avoids arranging a test that cannot give results. We survey roof terraces and balconies, liquid-applied waterproofing and flat roof membranes, and people most often book us about leaking laps in the waterproofing and damp inside with no sign on 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 Avery Hill, 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.
It is not only a list of defects. It explains what we found, why it matters and what we recommend, so you can decide what to do next.

Can I check my roof myself?
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, which helps when we check the roof.
Flat and commercial roofs around Avery Hill
About 1.2 miles west lies Eltham Palace, a reminder of how long the area around Avery Hill has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, frequently with hipped roofs of clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Anyone responsible for a site like Stationers' Crown Woods Academy will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. As a London address, Avery Hill can be tricky for parking: let us know about parking bays, permits or a driveway as you book, as a space near the door cannot be promised. Shop and office owners around Broadway Shopping Centre may find that a flat roof over a business is out of sight and out of mind until it leaks.

What affects the cost of electronic leak detection
We confirm the price for your roof before you book. This is what makes a difference:
- The type of building, from a house to a block or an office
- Whether thermal imaging or a drone is needed
- How many separate roofs there are, such as extensions, dormers and garages
- How tall the building is and how easy the roof is to see
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You will know the price for your survey before booking.

Avery Hill: your questions answered
Is parking a problem for a survey in Avery Hill?
London parking needs a little planning, so let us know about permits, bays or a driveway as you book. The visit is then planned around what’s available.
Do you cover Avery Hill?
Yes. Our area covers London and the South East, and Avery Hill is part of that. You can ring 07833 053749 or email us with the address and some details.
Do I have to be there for the survey?
That depends on the survey. For inside areas and the roof space, someone has to give us access, while outside access can be discussed when you book.
How long does electronic leak detection take?
The roof’s size and build-up decide how long it takes. We will give you an idea when we quote.
Can every flat roof be tested?
ELD does not suit every roof. Certain membranes are conductive, and some build-ups lack a suitable layer below. We will tell you if yours isn’t suitable before testing.
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.
Do you climb onto every roof?
Not always. Safety comes first, and fragile or steep roofs cannot always be walked on. We use safe viewpoints, the loft space and a drone where it applies.
