Electronic leak detection for homes and businesses in Sacombe
Electronic leak detection works on many flat roof membranes, on homes, blocks and commercial buildings. It can be used to trace an existing leak or check a new membrane before handover. Each roof is quoted on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays when conditions allow. Just ask about your roof. We survey commercial flat roofs, roof terraces and balconies and liquid-applied waterproofing, and people most frequently book us about new membranes needing a check before handover and gaps at membrane joints.
Older buildings in small places like Sacombe may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you’re planning work, check with the council first. Knowing the roof’s condition is the starting point. Listed building consent is needed for changes that affect a listed building’s special interest.
Nothing in the report is left vague: if work is needed, the report says so clearly, and where it can wait, that is said too.

Your questions about electronic leak detection in Sacombe
Is my home in Sacombe listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Will you come out to Sacombe?
Yes. Sacombe is within the area we cover, which takes in towns, villages and rural addresses. Our area covers London and South East England. Just mention lanes, gates or anything else about the route when booking.
Can every flat roof be tested?
It depends on the membrane and the build-up. Share any details you have and we will confirm suitability.
How much does electronic leak detection cost?
We quote for each roof individually. Send us details of the roof, and phone 07833 053749 or send us an email for a quote.
Can you test a green or ballasted roof?
Sometimes. The layers on top and the build-up below decide it and parts may need to be lifted. We’ll discuss it before we quote.
Are you structural engineers?
No. We are experienced roof surveyors, and visible signs like sagging are noted, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.
Is the repair part of the test?
No. We test the membrane and report. The report shows where each breach is so your roofer can fix them.
DIY checks: what’s safe
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.
What happens on the day
Photographs are taken throughout the visit, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available.

What electronic leak detection looks like in Sacombe
Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Next to the main roofs there is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. The wider area around Sacombe has a long history of building, with Aston Bury about 3.7 miles west. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material.
For an older house near a landmark such as Church of St Katherine, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
