Electronic leak detection in Denton, East Sussex
Know where you stand with the flat roof membrane before you spend money on it. We carry out electronic leak detection in Denton.
- Breaches hidden under paving or planting
- Leaks that return after repairs
- Leaks through a flat roof with no obvious cause
Do you need electronic leak detection in Denton?
Water travels under flat roof membranes. The leak may show some distance from where water gets in which makes it hard to find by looking.
Common reasons to book include:
- Stains far from any visible defect
- Holes left by work on the roof
- Holes around roof penetrations
- Leaks through a covered membrane
If you look after a building such as Denton Community Primary School and Nursery, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Before booking anyone
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Whether the loft space is looked at, where there is one
- What the report includes, and whether it has photos
- Whether they hold professional indemnity and public liability insurance
Electronic leak detection in Denton: what you get
Some flat roofs can’t be tested electronically. Certain membranes conduct electricity, and some build-ups lack the layer the test needs below the membrane. We will say if ELD won’t work on your roof at the start. Telling us what you know about the roof’s membrane and layers helps, including drawings, specifications or the roofer’s paperwork. It saves a wasted visit. If you’ve noticed leaking laps in the waterproofing and a flat roof leak that can’t be traced, a survey will tell you what’s going on, whatever the roof.
Around a smaller place like Denton, flat roofs typically cover extensions, garages and dormers. They’re small, but a leak over a kitchen extension can do a lot of harm. Knowing the covering and how it was laid tells you what to expect from it. From an upstairs window, look for standing water, splits and edges coming away.
Findings are set out part by part, from the main slopes down to the gutters and outlets. You will see the good as well as the bad.

What we do, step by step
Every roof is different, but as a rough guide the survey takes as long as needed for the membrane area and the build-up, which we set out in the quote. You are welcome to ask questions while we are there. Being in a smaller place like Denton doesn’t change how the visit works: outside, inside and from any safe vantage point, in that order. It’s useful to show us anything you’ve already noticed.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- The roof is assessed to see if electronic testing will work on it.
- We pick the low-voltage or high-voltage method that suits the roof.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photos in a report for your roofer.
Before the survey
- If you are buying, check with the agent that we can get in
- Clear the way to the loft hatch
- Make a note of anything you’d like us to look at
How to book
We confirm the price for the job before you book, so you know the cost up front. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, call 07833 053749 or send us an email.
Advice
What we look for on each type of roof
Inverted and paved roofs
On inverted roofs, insulation sits above the membrane and that changes how testing works.
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Testing may still be possible, depending on the build-up.
What electronic leak detection doesn’t cover
Without opening up the roof, some things stay hidden, so a survey has limits:
- Leaks from walls, copings or rooflights
- Repairing the breaches (that is for your roofer)
- Roofs whose membrane or build-up is not suitable
Not sure which survey suits your roof? You can call 07833 053749 or drop us an email and we will tell you before you book. What a survey covers and does not.

Flat and commercial roofs around Denton
Denton is within about 2 miles of the coast, and being near the sea means more wind and salt than a roof inland would face. Wind can catch loose edges and trims on a flat roof, and salt air is hard on metal trims, flashings and fixings. In Sussex, older roofs are frequently handmade clay tile, frequently with tile-hanging on the walls below. A few old Sussex buildings still carry heavy Horsham stone slabs, and the county’s older buildings include oast houses and Wealden hall houses. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If you own one of the older houses in the streets near Church of St Leonard, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. Historic houses such as Monk's House, about 3.1 miles north-west, show how far back building around Denton goes. If your home is older, its flat-roofed extension or dormer may be on its second or third covering.
Denton is about 1 mile north-east of Newhaven, in East Sussex. Denton is part of the area we cover and the surrounding area as part of our work across London and the South East. Denton is one of the towns and villages in East Sussex where we work. We also survey roofs in Brighton.
Postcode districts we cover here for electronic leak detection: BN9. Streets in the area include New Road, Avis Road and Hill Road, all of which we cover.

Denton: your questions answered
Is the coastal weather around Denton hard on roofs?
Near the coast, roofs face more wind and more salt than further inland. Salt corrodes metal fixings and flashings, and wind lifts loose slates, tiles and ridge pieces.
Do you cover smaller places like Denton?
Yes, Denton is on our map. Villages and rural addresses get the same survey as a town house.
Which method do you use?
We choose the method that suits the roof. We’ll explain why when we quote.
What’s the price of ELD?
Electronic leak detection is quoted for your roof, because the method depends on the roof. Size, build-up and access all affect the price. To get a quote, call 07833 053749 or send us an email.
Is this an asbestos survey?
No. We can flag materials that might contain asbestos, but confirming it is a job for a specialist asbestos surveyor. It may be present in buildings built or refurbished before 2000.
Can you survey at the weekend?
We survey on any day from Monday to Sunday, during the day. Just say which days work for you.
How long will testing take?
It depends on the size of the roof and its build-up. You’ll know roughly how long before we start.
Can I check my roof myself?
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Leave it or get it looked at?
Repairs in the wrong place leave the leak in place. ELD shows the actual breach points. With lower homes, common in places like Denton, there’s little between a roof defect and the ceiling, so a small leak can mark a ceiling within a few storms. Finding the cause first saves a second job inside.
The cost of a survey depends on the roof: 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.
