- Moisture spread under the membrane
- Roofs whose membrane or build-up isn’t suitable
- Repairing the breaches (that’s for your roofer)

Electronic leak detection in Headley Down: what you get
A leak in a flat roof often shows up a long way from where the water gets in. So the stain inside rarely sits under the hole. Electronic leak detection tests the membrane itself and locates the breach. We test and report, and the repair is for your roofer. On suitable roofs, it replaces guesswork with a located breach. The results then follow in a written report with photos. We survey green roofs, roof terraces and balconies and commercial flat roofs, and the problems we are asked to look at most are a flat roof leak that can’t be traced and waterproofing to test before it’s covered.
Around a smaller place like Headley Down, flat roofs usually cover extensions, garages and dormers. They’re small, but a leak over a kitchen extension can do a lot of harm. What it is covered in, and how well it was laid, decides what it needs, from felt and asphalt to EPDM rubber and GRP. From an upstairs window, look for standing water, splits and edges coming away.
We write the report in plain English, so it makes sense without any roofing background. Each point is backed by a photo where possible, and recommendations are put by urgency where it matters.

Signs you need electronic leak detection in Headley Down
Joints and laps in a membrane can fail over time. A gap that’s hard to see can let water in long before anyone notices.
Here are some of the things we see often:
- Punctures from foot traffic or tools
- Breaches hidden under paving or planting
- Waterproofing to test before it’s covered
- Leaks at pipes, outlets or fixings
Take a building like The Holme Church of England Primary School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Before you book anyone
- How long the report takes to arrive
- Do they have a CAA Flyer ID and Operator ID for drone work?
- What the report includes, and whether it has photos
- Is VAT included in the price?
What a survey costs
A few things affect what a survey costs:
- How many separate roofs there are, such as extensions, dormers and garages
- Chimneys, valleys, parapets and other details
- If the survey needs thermal imaging or a drone
- Roof area
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You will know the figure before booking.
Booking your survey
If you can, have these to hand when you contact us:
- The style of property, from a terrace to a block
- Pictures of the roof from a safe spot, if you have them
- What’s prompted the survey
- Your postcode, so we can check access and travel
Booking is simple: just call 07833 053749 or drop us an email, let us know about the property and we will suggest the right survey. The price is agreed up front.
Electronic leak detection around Headley Down
What can be done to an older roof may depend on listing or a conservation area. Your council and Historic England’s list will tell you where you stand, ideally before any re-roofing is planned. Thatch survives on some older buildings in Hampshire’s villages. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
The streets around a church such as Church of All Saints are frequently among the oldest in a place, and if your house is among the older ones nearby, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. For landlords with property near Liphook station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

The survey, step by step
Photos are taken throughout the visit, so the report shows exactly what we saw. We take close-ups from wherever is safe. A typical visit takes as long as needed for the size of the roof and how it’s built, which we set out in the quote. With a bit of garden around a house, as there frequently is around Headley Down, the roof can be viewed from several angles. Let us know if any side is fenced off or hard to reach. The loft, where there is safe access, completes the picture.

Advice
What else we do in Headley Down
What you can safely check yourself
A DIY look is useful, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground, and those are details a survey looks at closely.
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Do not go up yourself.
FAQs for Headley Down
Is Headley Down within the area you cover?
Yes, we do. We survey roofs across London and South East England, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Does a conservation area affect roof work in Headley Down?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
How do I book a survey in Headley Down?
The quickest way is to call 07833 053749 or email us. Let us know the address and a little about the roof, and we’ll take it from there. Surveys run on any day of the week.
Is it a structural engineer’s report?
No. Our survey isn’t a structural engineer’s report, and it doesn’t include calculations. We’ll recommend an engineer if we see signs that call for one.
How long does electronic leak detection take?
The roof’s size and build-up decide how long it takes. You will know roughly how long before we start.
Do you test for asbestos?
No. Asbestos surveys and testing aren’t part of what we do. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings, and recommend a specialist asbestos surveyor checks them before they’re disturbed.
What does electronic leak detection do?
It uses an electrical current to find breaches in a flat roof membrane. A breach lets the current through, which shows us where the hole is.
Why get it checked now?
Patching where you think the leak is often misses it. ELD shows the actual breach points. Homes in smaller places like Headley Down can face more weather, so a loose ridge or verge soon lets rain in. Wind gets under it and lifts more.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Why us?
