Electronic leak detection for homes and businesses in Netteswell
Water can travel under a flat roof membrane before it shows inside. So the stain inside rarely sits under the hole. Electronic leak detection tests the membrane itself, to find where it has been breached. It is testing only and leave the repair to your roofer. On suitable roofs, it replaces guesswork with a located breach. The results then follow in a written report with photos. If you are worried about patched roofs that still leak and breaches hidden under paving or planting, we can find out what’s behind it, on green roofs, liquid-applied waterproofing and commercial flat roofs alike.
Outbuildings, garden rooms and garages in places like Netteswell often have flat roofs of their own. They’re rarely looked at until something gets wet. It is worth mentioning them when you book, so the visit can include them. Smaller roofs use the same coverings as bigger ones, from felt to rubber and GRP, and age in the same way.
Nothing in the report is left vague: where something needs attention, it says so plainly, and where it can wait, that’s said too.

How we price electronic leak detection
We confirm the price for your roof before booking. This is what makes a difference:
- The size of the roof
- The number of roofs, including extensions and garages
- Chimneys, valleys, parapets and other details
- Building height and the viewpoints available
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 safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
What we need to know
There’s no need for technical words. Just let us know:
- How the loft is reached, if there is one
- Any stains, drips or damp patches you’ve seen indoors
- Why you want a survey: buying, a leak, a storm or new work
- Any photos you have, taken from the ground or a window
Every survey is priced before it is booked, so you know the cost up front. Electronic leak detection is quoted for your roof, because the method depends on the roof. To book, phone 07833 053749 or email us.
Flat and commercial roofs around Netteswell
Weatherboarded walls and clay tile roofs are typical of older Essex buildings, with post-war and more recent estates making up much of the newer housing. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops. If your home is older, it is worth knowing whether it’s listed or in a conservation area before planning roof work. Changes that affect a listed building’s special interest need listed building consent, and councils can also use Article 4 directions to control changes in conservation areas.
If you let a flat or house near Harlow Town station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. For site and facilities teams at buildings such as Freshwaters Primary Academy, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.

Netteswell questions
Will you come out to Netteswell?
Yes, Netteswell is covered. We survey roofs across London and the South East, from towns to the smallest villages. The journey is planned ahead, so it’s useful to know about access.
Is my home in Netteswell listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
Can you survey at the weekend?
Surveys can be booked for any day of the week: weekdays, Saturdays and Sundays. Just let us know the days that suit you.
What insurance do you have?
We’re covered by professional indemnity and public liability insurance.
What’s in the report?
It sets out what we found, why it matters and what we recommend, with photographs throughout. It also says if any part of the roof couldn’t be seen safely.
Can every flat roof be tested?
ELD does not suit every roof. Some membranes conduct electricity, and some build-ups lack a suitable layer below. If your roof won’t work, we’ll say so at the start.
How does ELD work?
The waterproofing membrane normally stops an electrical current, but a hole lets it through. That lets us find breaches that are too small to see.
Common roof problems in Netteswell
When the membrane is buried, holes cannot be seen at all. ELD can work on some covered roofs, depending on the build-up.
Signs worth acting on include:
- Failed seams and laps
- Leaks that return after repairs
- New membranes needing a check before handover
- Leaks at pipes, outlets or fixings
Take an older house close to St Andrew's Methodist Church: flat-roofed rear additions and dormers added over the years are worth checking.
Before booking any roof surveyor
- Are they insured for the work?
- Which parts of the roof they’ll actually see
- Their track record with similar roofs
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
What happens on the day
Safety comes first on every visit. Everything that can be seen safely is inspected, and if part of the roof can’t be seen, the report says so. Most visits take a time that depends on the roof’s area and construction, which we set out in the quote. A visit to a smaller place like Netteswell is no different on the day: we look from ground level, from windows, from the loft and from the roof where it’s safe. It helps to show us anything you’ve already noticed.
- We agree the area to be tested.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Before we arrive
- If you are buying, check with the agent that we can get in
- Tell us about any leaks, stains or damp patches you know of
- For flats, make sure roof access has been agreed
Getting a price
We survey roofs seven days a week. To find a date that works for you, ring 07833 053749 or send us an email with the address and the days you’d prefer.
Advice
How the survey changes by roof type
Bituminous membranes
Many flat roofs use bitumen-based membranes. Whether ELD suits them depends on the build-up.
Liquid-applied waterproofing
Pinholes in a coating can let water through. ELD can help locate them on suitable roofs.
Useful tips for Netteswell property owners
Here are a few things we’d tell any owner, before and after a survey:
- Don’t keep patching the same spot
- Keep a note of leaks after rain
- Get leaks traced quickly
- Do not let outlets block
If water has been getting in, insulation under the membrane may be wet. Your roofer can advise on that and other checks can help judge it.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.
Rented homes, blocks and businesses
We survey roofs for landlords and letting agents as well as homeowners. The report gives you a dated record of the flat roof membrane, with photographs.
Roof problems in a rented home affect tenants as well as the building. A survey shows what needs attention, so you can plan the work with less disruption.
