How electronic leak detection works in Northfleet Green
We carry out electronic leak detection on flat roofs in Northfleet Green and across London and the South East. Testing usually 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. Typical surveys look at damp inside with no sign on the roof and leaks at pipes, outlets or fixings, on roof terraces and balconies, commercial flat roofs and single-ply roofs.
Flat roofs on exposed homes in small places like Northfleet Green take more wind and rain, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, usually show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
The report does not just list problems. For each finding, it explains what it is, why it matters and what we’d recommend, so you can plan your next steps.

Northfleet Green: your questions answered
Does being near the coast affect roofs in Northfleet Green?
Often, yes. Northfleet Green is within about 4 miles of the sea, and coastal roofs tend to see faster wear on metal parts and more wind lifting loose pieces.
Do you cover smaller places like Northfleet Green?
Yes, Northfleet Green is on our map. A small place gets exactly the same survey as a big one.
What does the report include?
It works through the roof part by part, in writing and with photos. The most urgent items are made clear.
Do you climb onto every roof?
Only where it’s safe to do so. We inspect whatever is safely visible: from the ground, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where applicable. Anything we cannot see is noted in the report.
Do you use low-voltage or high-voltage testing?
It depends on the membrane and the build-up. Low-voltage methods are typically carried out on a wet roof and high-voltage methods need the membrane dry and exposed.
How is ELD priced?
We quote for each roof individually. Send us details of the roof, and phone 07833 053749 or email us for a quote.
Is this a RICS survey?
No. Our survey looks at the roof, not the whole building. If you need a full building survey, you will need a RICS survey as well.
What a survey costs
To price your survey, we check:
- Roof area
- The shape of the roof and its details
- Extra roofs, like extensions, dormers or garages
- Commercial roofs and larger buildings
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.
Booking your survey
You do not need to know any roofing terms. It’s enough to let us know:
- Your postcode, so we can check access and travel
- When you need the report by
- Where any leaks, stains or damp patches show inside
- Why you want a survey: buying, a leak, a storm or new work
Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. For any other survey, just call 07833 053749 or drop us an email when you are ready.
Electronic leak detection in Northfleet Green: local notes
Northfleet Green lies within about 4 miles of the sea, so there’s more wind and more salt in the air than further inland. Wind can catch loose edges and trims on a flat roof, and salt air is hard on metal trims, flashings and fixings. Many older homes in Kent have handmade clay tiles, including Kent peg tiles held by pegs through two holes, and tile-hanging on their upper walls. Oast houses and timber-framed Wealden hall houses are part of the county’s older buildings too. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
Anyone responsible for a site like Painters Ash Primary School will know that schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks. If you own a rental within reach of Ebbsfleet International station, the flat roof over a let home is worth a look before it becomes a tenant complaint. If your home is one of the older ones in the streets near Church of St Nicholas, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

Should I look at the roof myself first?
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, as it helps a surveyor trace the cause.
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
Tips from our surveys
Here are a few things we’d tell any owner, before and after a survey:
- Keep a note of leaks after rain
- Don’t let outlets block
- Share any drawings of the roof
- Ask contractors to protect the membrane
After your roofer repairs the breaches, a retest can confirm them if the build-up allows.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
How it works
A survey visit follows a simple order: we listen to what’s been worrying you, look at the roof from every safe viewpoint, photograph what we find and make notes for the report. Most visits take more time on a big roof than a small one, and the build-up of the roof makes a difference too. Somewhere like Northfleet Green needs a little journey planning: let us know about narrow lanes, gates, long drives and where we can park. On the day, we inspect whatever is safely visible, inside and out.
- First, you tell us about the roof build-up and where water is showing.
- We check that the membrane and build-up suit electronic leak detection.
- The method depends on the membrane and what sits above and below it.
- 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.
Preparing for the visit
- Leave a clear route to the loft
- Buyers: confirm access with the estate agent or seller
- Make a note of anything you’d like us to look at
