Electronic Leak Detection in Dunsbury
Electronic leak detection for homes and businesses in Dunsbury. We’ve completed more than 5,000 surveys across London and the South East.
- Repairs that haven’t stopped the leak
- Leaks showing away from the breach
- Breaches around outlets and penetrations
How electronic leak detection works in Dunsbury
Our ELD report shows where each breach was found with photos. It tells your roofer exactly where to repair rather than guessing. We don’t estimate repair costs, so your roofer prices the work. A retest after repairs can check the work, where the roof still suits the method. You get a written report with photos. We survey flat roof membranes, roof terraces and balconies and commercial flat roofs, and common reasons people get in touch are failed seams and laps and damage from equipment installers.
Flat roofs on exposed homes in small places like Dunsbury take more wind and rain, which is hard on edges, upstands and joins in the covering. 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.
Nothing in the report is left vague: if work is needed, the report says so clearly, along with how urgent it is.

What we cannot see
In fairness, there are limits to any roof survey:
- Sections we can’t safely access
- How wet the insulation is
- Some conductive membranes
Not sure which survey suits your roof? You can phone 07833 053749 or email us and we will tell you. What our survey covers.
Roof types and parts we check
- Single-ply roofs
- Liquid-applied waterproofing
- Commercial flat roofs
- Flat roof membranes
- Roof terraces and balconies
- Green roofs
What affects the price in Dunsbury
We confirm the price for your survey before you book. This is what makes a difference:
- Any need for thermal images or a drone flight
- The shape of the roof and its details
- The roof’s overall size
- The type of building, from a house to a block or an office
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.
Booking your survey
What helps most when you contact us:
- Where any leaks, stains or damp patches show inside
- Any deadline, such as an exchange date
- Access details, such as a loft hatch or a shared roof
- What made you get in touch
Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, call 07833 053749 or email us.
How the survey works
On the day, we begin with a quick chat about the roof and anything that is worrying you. After that, we check everything we can see safely, from the ground, from windows, in the roof space and by drone where applicable. Most surveys take longer on a large roof than a small one, with the construction of the roof playing a part too. In a hamlet or village like Dunsbury, a postcode doesn’t always lead to the right gate, so a few directions are welcome. After that, the survey runs as it would anywhere.
- We start by finding out what the roof is made of and where it leaks.
- We confirm whether the roof is suitable for electronic testing.
- We pick the low-voltage or high-voltage method that suits the roof.
- The roof is tested and any breaches are located.
- The breaches are recorded with photos in a report for your roofer.
Preparing for the visit
- If you’re buying, check with the agent that we can get in
- Keep pets in another room
- Check we can get to the back of the property
Arrange a survey
Booking is simple: just ring 07833 053749 or send us an email, tell us about the property and we will recommend the right survey. We confirm the price before anything is booked.

Common roof problems in Dunsbury
Work on the roof can damage a membrane. Fixings, equipment and foot traffic can leave small holes.
A survey makes sense if you’ve noticed:
- Holes around roof penetrations
- Patched roofs that still leak
- New roofs to check before paving or planting
- Stains far from any visible defect
Mottistone Manor lies about 1.2 miles east, so building around Dunsbury goes back a long way. If your home is older, its flat-roofed extension or dormer may be on its second or third covering.
Questions to ask before you book
- Is there a chance to talk the report through?
- Whether VAT is in the quoted price
- Their drone registration, if they fly one
- What experience they bring
Useful tips for Dunsbury property owners
Small things make a difference. Our tips:
- Avoid repeated repairs without finding the cause
- Note where leaks show inside and when
- Tell us about the membrane and build-up if you know it
- Check trades protect the waterproofing
The report records each breach location with photos. Pass it to your roofer to repair the breach points.
Check contractors protect the waterproofing when they work up there. Check the roof after they’ve finished.
What we look for on each type of roof
Inverted and paved roofs
Paving and terraces cover the membrane. Suitability depends on the layers.
Green and ballasted roofs
Testing before planting or ballast goes on is simpler.
Flat roofs in Dunsbury
The coast is about 1 mile or less from Dunsbury, where sea air brings more salt and stronger wind than inland. Wind can catch loose edges and trims on a flat roof, and salt air is hard on metal trims, flashings and fixings. Thatch survives on some older Isle of Wight buildings, and the whole island is open to sea air and wind. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Take an older house close to St. Mary's Church: flat-roofed rear additions and dormers added over the years are worth checking.
Dunsbury is about 7 miles south-west of Newport, in the Isle of Wight. We survey roofs in Dunsbury and the surrounding area across London and South East England. Our the Isle of Wight coverage includes Dunsbury. For surveys nearby, see our Southampton page.

If you are just outside Dunsbury, we cover Brook (1 mile south), Hulverstone (1 mile south-east), Brookgreen (1 mile south-east), Shalcombe (1 mile north-east) and Chilton Green (2 miles south-east).

Dunsbury questions
Is the coastal weather around Dunsbury hard on roofs?
It can do. Within about 1 mile of the sea, as Dunsbury is, metal fixings wear faster and gales find any loose ridge or slate.
Is my home in Dunsbury listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
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.
What do I do with the report?
The report comes by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
Do you use low-voltage or high-voltage testing?
The roof decides the method. We will explain why when we quote.
Do I have to be there for the survey?
If the survey includes the loft or the inside of the building, someone needs to let us in. We will talk about access when you book.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and sampling are not something we do. Where a material might contain it, such as old cement sheets on a building from before 2000, the report flags it, with a recommendation to have a specialist asbestos surveyor check before it is disturbed.
