Electronic leak detection in Turnpike Lane
Water can travel under a flat roof membrane before it shows inside. So the stain inside rarely sits under the hole. Electronic leak detection tests the membrane itself and locates the breach. We test and report, and the repair is for your roofer. On a suitable roof, it takes the guesswork out of finding the hole. We then send you the results in a written report. We survey liquid-applied waterproofing, single-ply roofs and roof terraces and balconies, and the problems we’re asked to look at most are leaks that return after repairs and water coming in under a flat roof.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a block or conversion in Turnpike Lane, the flat roof is frequently a shared part of the building.
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.

What we look for on each type of roof
Single-ply membranes
Some single-ply membranes suit electronic testing well, depending on the type and build-up.
EPDM rubber roofs
ELD on EPDM depends on the product and the layers. We look at this first.
Tips from our surveys
You do not need to be a roofer to help. What helps most:
- Limit access to the roof
- Keep a note of leaks after rain
- Don’t let outlets block
- Do not keep patching the same spot
Once repairs are made, the roof can be tested again if you want to check them, where the roof still suits the method.
Consider testing a new membrane before it’s covered. It is easier to find holes before more layers are added.
Electronic leak detection around Turnpike Lane
Many homes in inner London are Victorian and Edwardian terraces, often with Welsh slate roofs. Behind many of their parapets sit butterfly roofs and valley gutters that can’t be seen from the pavement. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops. The wider area around Turnpike Lane has a long history of building, with Bruce Castle about 1.5 miles north-east. If you own one of the older houses, 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.
If you look after a building such as North Harringay Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. Turnpike Lane is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book, as a space near the door can’t be promised. If you let a flat or house near Hornsey station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

What you can safely check yourself
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, which helps when we check the roof.
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
Prices for electronic leak detection in Turnpike Lane
Every roof is different, so prices are confirmed before booking. These are the things that affect it:
- Height and safe access
- The roof’s overall size
- How many separate roofs there are, such as extensions, dormers and garages
- Chimneys, valleys, parapets and other details
For a price for your roof in Turnpike Lane, ring 07833 053749 or email us with the address and some details. We’ll confirm the figure before booking.
What we need to know
You don’t need to know any roofing terms. It’s enough to let us know:
- The reason for the survey, like buying, a leak or storm damage
- Any deadline, like an exchange date
- The address and postcode of the property
- The style of property, from a terrace to a block
We confirm the price for your roof before you book, so you know where you stand. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, ring 07833 053749 or drop us an email.
What we do, step by step
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. You are welcome to ask questions while we’re there. In a London area like Turnpike Lane, the main things to sort out are parking and access: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at everything that’s safely in view from the ground, windows, the loft and, where it is safe, the roof itself.
- First, you let us know about the roof build-up and where water is showing.
- We check that the membrane and build-up suit electronic leak detection.
- We pick the low-voltage or high-voltage method that suits the roof.
- We test the membrane and find where current is passing through it.
- We send a report with photos of each breach so your roofer can repair it.
Before the survey
- Move anything stored under the loft hatch
- Find any records of previous roof work
- Let us know where we can park nearby
