About our electronic leak detection in North Brixton
Our ELD testing covers flat roofs in North Brixton and the rest of London and South East England. A visit normally takes as long as needed for the size of the roof and how it’s built, which we’ll explain when we quote. Electronic leak detection is quoted for your roof, because the method depends on the roof. The results come in a written report with photos. If you’re worried about leaks under green or ballasted roofs and repairs that haven’t stopped the leak, we can find out what’s behind it, whatever the roof.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, each with its own weak points. In North Brixton, as anywhere in London, the right approach depends on what the roof is made of. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
Findings are set out part by part, from the coverings down to the gutters, each with a short note and a photograph. You’ll see the good as well as the bad.

Signs you need electronic leak detection in North Brixton
A breach can be left during installation. Testing before the roof is covered or handed over helps find them.
Here are some of the things we see frequently:
- Gaps at membrane joints
- Stains far from any visible defect
- New roofs to check before paving or planting
- Holes around roof penetrations
If you live in an older home near St Michael's Church, the joins between later flat roofs and the old walls are where problems typically start.
What to check before booking
- What experience they bring
- Will the report include photos?
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- What follow-up you get after the report
What we do, step by step
We check the roof from outside and, where it’s relevant and there’s safe access, from inside the roof space too. Inside, we look for staining, damp, gaps and signs of movement. All in, the survey normally takes longer on a large roof than a small one, with the construction of the roof playing a part too. From the street, a London terrace typically shows only its front slope or parapet, so a visit in North Brixton moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Tell us who holds the keys.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
Preparing for the visit
- Buyers: confirm access with the estate agent or seller
- Check pets are kept safely away
- Make a note of anything you’d like us to look at

Electronic leak detection around North Brixton
Historic houses like Buckingham Palace, about 2.3 miles north-west, show how far back building in the area around North Brixton goes. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
Landlords with a home close to Loughborough Junction station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies. Anyone responsible for a site like Van Gogh Academy will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

North Brixton: your questions answered
How do I find out if my home in North Brixton is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Will parking be an issue for a roof survey in North Brixton?
Sometimes, yes. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well, and a driveway is even better.
What’s the price of ELD?
We quote for each roof individually. Let us know about the roof and where it leaks, and ring 07833 053749 or drop us an email for a quote.
Can every flat roof be tested?
Not every roof is suitable. Some membranes conduct electricity, and some build-ups lack a suitable layer below. If your roof will not work, we’ll say so at the start.
What will the report tell me?
It explains what we saw, what it means and what we’d suggest, backed by photographs. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
What insurance do you have?
We’re covered by professional indemnity and public liability insurance.
How do I arrange electronic leak detection in North Brixton?
Simply ring 07833 053749 or drop us an email with the address. After a few questions, we confirm the price and fix a day.
Before and after the survey
You do not need to be a roofer to help. Here’s what helps most:
- Note where leaks show inside and when
- Check new waterproofing before handover
- Avoid repeated repairs without finding the cause
- Do not let outlets block
If anything in the report is not clear, ask us. We will explain what was found and what it means.
Ask trades working on the roof to protect the membrane when fitting equipment. Have the roof looked at after other work.
Should I look at the roof myself first?
A DIY look is useful, but it isn’t a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground.
A lot can be seen from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
Why act early in North Brixton
Leaks left running can wet the insulation and deck. Finding the breach sooner limits that. London’s older roofs frequently have bitumen felt underlay or none at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left unchecked, water soaks into timber and plaster and the damage spreads.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before you book.
