Northdown Electronic Leak Detection
Find out what’s going on with the flat roof membrane before you decide what to do next. We carry out electronic leak detection in Northdown, with photos and a clear written report.
- A flat roof leak that can’t be traced
- Patched roofs that still leak
- New membranes needing a check before handover
What affects the price in Northdown
When we price a survey, we consider:
- The size of the roof
- The number of roofs, including extensions and garages
- Chimneys, valleys, parapets and other details
- Whether it is a home or a commercial building
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. We quote electronic leak detection for each roof, as the method and time depend on the roof.
What to tell us when you contact us
We will typically ask about:
- The style of property, from a terrace to a block
- Why you want a survey: buying, a leak, a storm or new work
- Pictures from the garden or a window, if you have them
- Your timetable, such as an exchange date
A quick phone call is usually the easiest start: call 07833 053749 or use the contact form and we’ll ask a few questions about the roof. You’ll have a price before anything is arranged.
Electronic leak detection in Northdown: what you get
Our ELD report shows where each breach was found, with photographs. It tells your roofer exactly where to repair rather than guessing. Repair costs aren’t part of the report; that is for your roofer to price. A retest after repairs can check the work, where the roof still suits the method. You get a report with photographs. We’re often asked to look into damage from equipment installers and leaks showing away from the breach, on flat roof membranes, liquid-applied waterproofing and green roofs.
Around Northdown, many homes have a garden room, garage or outbuilding with a flat roof. They’re easy to forget, but water through a garage roof can spoil whatever is stored inside. If you want them looked at too, mention them when booking. Smaller roofs use the same coverings as bigger ones, from felt to rubber and GRP, and age in the same way.
Every survey ends with a written report, with photos, sent by email. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

Northdown questions
Is Northdown within the area you cover?
Yes. Northdown is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Just mention lanes, gates or anything else about the route when you book.
Does a conservation area affect roof work in Northdown?
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. 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.
How fast do I get the report?
That depends on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. The report is emailed to you.
What if it rains on the day?
A survey can usually go ahead in light rain, and it can even help show where water is getting in. Strong wind or a downpour can stop drone flights and make roof access unsafe, so if conditions are not right we will arrange another day with you.
What is electronic leak detection?
The waterproofing membrane normally stops an electrical current, so wherever there’s a hole, it passes through. That lets us find breaches that are too small to see.
Which days do you carry out surveys?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Let us know your preferred days when you book.
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.
What we do, step by step
We work from the outside in: outside views come first, then the roof space if there’s safe access. In total, it takes longer on a large roof than a small one, with the construction of the roof playing a part too. In a smaller place like Northdown, parking is seldom the issue; lanes, gates and long drives are worth mentioning. On bungalows and lower roofs, much can be seen from ground level, with the loft showing the underside.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We confirm whether the roof is suitable for electronic testing.
- We pick the low-voltage or high-voltage method that suits the roof.
- Testing runs across the roof to locate breaches in the membrane.
- You get a report showing where each breach is, for your roofer to repair.
Preparing for the visit
- Move anything stored under the loft hatch
- Jot down any questions you want answered
- Keep pets out of the way during the survey

Flat and commercial roofs around Northdown
The coast is about 1 mile or less from Northdown, where sea air brings more salt and stronger wind than inland. On a flat roof near the sea, edge trims and upstands take the brunt of the wind, and metal parts corrode faster. Older houses across Kent often have handmade clay or peg tiles, and many have tile-hung walls. Oast houses and timber-framed Wealden hall houses are part of the county’s older buildings too. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If you look after a shop, office or commercial unit, for example near Westwood Cross, outlets and upstands on commercial flat roofs are the places to check before trouble starts. If you let a flat or house near Broadstairs station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. With Quex Park about 4.5 miles west, the area around Northdown has a long history. On a period home nearby, any flat roof is likely to be a later addition with its own lifespan.

What you can safely check yourself
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can point to a blockage or a sagging run.
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 look at the roof.

What we look for on each type of roof
Inverted and paved roofs
If the build-up rules out ELD, we’ll say so.
Bituminous membranes
Bituminous felt and modified bitumen membranes are common. Whether ELD suits them depends on the build-up.
Useful tips for Northdown property owners
Over many surveys, some simple habits stand out as worth the effort:
- Do not let outlets block
- Don’t keep patching the same spot
- Don’t leave water getting in
- Keep a note of leaks after rain
File the report with your roof paperwork. It shows the condition of the membrane on that date.
Make sure contractors protect the waterproofing when they work up there. Check the roof after they’ve finished.
For landlords and managing agents
We survey roofs for landlords and agents as well as homeowners. A written report with photos gives you a clear record of the flat roof membrane, useful for planning maintenance.
