Electronic leak detection in Vernham Dean: what you get
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It helps trace a leak you already have or to test a new membrane before it’s covered. Each roof is quoted on its size and build-up. We can test on weekdays and at weekends when conditions allow. Just ask about your roof. We survey single-ply roofs, commercial flat roofs and roof terraces and balconies, and common reasons people get in touch are breaches around outlets and penetrations and new membranes needing a check before handover.
Flat roofs on exposed homes in small places like Vernham Dean take more wind and rain, so edges, upstands and laps take a beating. Older felt roofs, frequently around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are normally the first part of a flat roof to go.
The report doesn’t 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.

Rented homes, blocks and businesses
Letting agents can arrange access with tenants, at a time agreed in advance. We survey on any day of the week, which helps when tenants work during the week.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, with the most urgent items set out first.
Common questions in Vernham Dean
Do you cover Vernham Dean?
Yes. We work right across London and South East England, and Vernham Dean is part of that. You can ring 07833 053749 or drop us an email with the address and some details, and we’ll talk through which survey suits.
Is my home in Vernham Dean 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.
Does the weather affect the survey?
It depends on the weather and the survey. In strong wind or heavy rain, a drone can’t fly and access may not be safe, so we’d move the date with you.
Do you test for asbestos?
No. We do not carry out asbestos surveys or testing. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them and suggest a specialist asbestos surveyor checks them before any work.
Do you climb onto every roof?
Only where it’s safe to do so. We inspect what can be seen safely: from the ground, from windows, from inside the loft space, from the roof where it is safe and by drone where applicable. Anything we can’t see is noted in the report.
How is ELD priced?
We quote for each roof individually. Send us details of the roof, and phone 07833 053749 or send us an email for a quote.
Which days do you carry out surveys?
We carry out surveys seven days a week. To arrange a date, ring 07833 053749 or drop us an email.
Other services in Vernham Dean
Do you need electronic leak detection in Vernham Dean?
A breach can be left during installation. ELD on a new roof can show holes before they cause leaks.
Signs worth acting on include:
- Waterproofing to test before it is covered
- Holes around roof penetrations
- Leaks showing away from the breach
- Water coming in under a flat roof
For site and facilities teams at buildings such as Vernham Dean Gillum's Church of England Primary School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.
Before you book any roof surveyor
- Will the report include photos?
- What experience they bring
- Whether any drone flown is registered with the CAA
- Whether the loft is part of the inspection
Local flat roofs in Vernham Dean
A number of Hampshire villages keep thatched roofs on their older buildings. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops. There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 conservation areas. If your 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, so check with the council.
For an older house near a landmark such as Church of St Mary, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

Prices for electronic leak detection in Vernham Dean
What a survey costs depends on the time and equipment it needs. That comes down to:
- How complicated the roof is, with its valleys, chimneys and parapets
- Roof area
- The use of thermal imaging or a drone
- Extra roofs, like extensions, dormers or garages
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You will know the figure before booking.
Booking your survey
Before you get in touch, it’s useful to have:
- Where water is showing inside, if it is
- Access details, such as a loft hatch or a shared roof
- The kind of building and roof involved
- Pictures of the roof from a safe spot, if you have them
A quick phone call is typically the easiest start: call 07833 053749 or email us and we will ask a few questions about the roof. The price is agreed before a date is set.
Practical tips
You don’t need to be a roofer to help. What helps most:
- Act on new leaks promptly
- Keep outlets clear of debris
- Test new membranes before covering them
- Share any drawings of the roof
Questions about the results are welcome. We will explain what was found and what it means.
Consider testing a new membrane before it’s covered. It is easier to find holes before more layers are added.
Roof by roof
Single-ply membranes
Single-ply can be punctured by tools or fixings. ELD can locate them.
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing and that changes how testing works.
What happens on the day
Once we have finished looking, we write up our findings in a report with photographs, sent to you by email. On timing, it usually takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Older roofs in small places like Vernham Dean can have low, tight loft spaces, so let us know about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- We start by finding out what the roof is made of and where it leaks.
- 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.
- Testing runs across the roof to locate breaches in the membrane.
- The breaches are recorded with photos in a report for your roofer.
Before the survey
- Note where any stains or damp appear
- Find any records of previous roof work
- If you are buying, check with the agent that we can get in
Getting a price
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’re ready.
