How it works
A survey visit follows a simple order: we listen to what’s been worrying you, inspect the roof from each safe vantage point, take photos as we go and make notes for the report. It usually takes a length of time set by the roof’s area and construction, and we’ll give you a guide when quoting. Surveys in Clapham Junction can be booked for any day of the week. It helps if you can point us to a visitor permit or a nearby bay. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- 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.
- The report is sent for your roofer to act on.
Preparing for the visit
- Make sure pets are kept safely away
- Make sure we can get to the back of the property
- Buyers: confirm access with the estate agent or seller

Electronic leak detection in Clapham Junction
Our ELD testing covers flat roofs in Clapham Junction and the rest of London and the South East. Testing normally takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. 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’ve noticed leaks showing away from the breach and patched roofs that still leak, a survey will tell you what’s going on.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Every penetration and upstand is a place where a membrane can fail. For a building in Clapham Junction, 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.
The report works through the roof section by section, from the main slopes down to the gutters and outlets, with a note and a photo for each point. You’ll see the good as well as the bad.

Why act early in Clapham Junction
Chasing a leak again and again is frustrating. A report showing the breach points gives your roofer a clear target. In a London terrace or conversion, a roof defect rarely stays your problem alone: failed flashings and blocked valley gutters can send water into more than one home. Finding it early keeps the work smaller.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.

Behind many of their parapets sit butterfly roofs and valley gutters that cannot be seen from the pavement. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.

Your questions about electronic leak detection in Clapham Junction
Is my home in Clapham Junction listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Can you look at the flat roof of a hotel or office near Clapham Junction?
Yes, commercial flat roofs are part of what we cover. For a bigger roof, you’ll get a quote based on the building, and roof access is agreed with you before the visit.
Does ELD include fixing the breach?
No. We test the membrane and report. The report shows where each breach is so your roofer can fix them.
Does the weather affect the survey?
It can, depending on the survey. Drones cannot fly safely in strong wind or a downpour, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. We’ll rearrange with you if the weather isn’t right.
What’s the best way to book?
Simply call 07833 053749 or send us an email. After a few questions, we confirm the price and fix a day, weekday or weekend.
