Passfield Electronic Leak Detection
We carry out electronic leak detection in Passfield and the rest of Hampshire. We survey on weekdays and at weekends.
- Repairs that haven’t stopped the leak
- Waterproofing to test before it is covered
- Leaks showing away from the breach
The survey, step by step
We do not take risks to get a closer look. We inspect whatever is safely visible, and anything we can’t see is noted in the report. Most visits take longer on a large roof than a small one, with the construction of the roof playing a part too. Older roofs in small places like Passfield can have low, tight loft spaces, so it helps to know whether there’s a loft hatch and how easy it is to reach. Only areas that can be reached safely are inspected.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Preparing for the visit
- Agree roof access with the managing agent if it is shared
- If you’re buying, let the agent know when we’re coming
- Jot down any questions you want answered
How to book
Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, phone 07833 053749 or send us an email.

Electronic leak detection in Passfield: what you get
Not every flat roof suits electronic testing. Certain membranes conduct electricity, and some build-ups lack the layer the test needs below the membrane. We will say if ELD will not work on your roof before any testing. Any details you have about the membrane and build-up help us decide, including drawings, specifications or the roofer’s paperwork. It saves a wasted visit. If you’ve noticed new roofs to check before paving or planting and a flat roof leak that can’t be traced, a survey will tell you what’s going on, on roof terraces and balconies, green roofs and commercial flat roofs alike.
Flat roofs on exposed homes in small places like Passfield 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. Rubber and GRP last longer, though trims and joints still need a look. On an exposed roof, the edges tend to go first.
After the visit, you get a report with photos, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

Before and after the survey
Most of what helps is simple and safe from ground level. Our suggestions:
- Keep foot traffic on flat roofs to a minimum
- Record dates and spots where water appears
- Clear flat roof outlets regularly
- Share any drawings of the roof
Questions about the results are welcome. We’ll explain what was found and what it means.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
What happens if roof problems are left?
Repeated call-outs for the same leak add up. A report showing the breach points gives your roofer a clear target. Outbuildings and barns around Passfield are easy to forget, but a failed roof there can spoil what’s stored inside. A quick look before winter can save a lot.
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.

What electronic leak detection looks like in Passfield
Before planning roof work on an older home, find out whether it is listed or in a conservation area. Listed building consent covers changes to a listed building’s special interest, and an Article 4 direction can bring extra controls in a conservation area. A number of Hampshire villages keep thatched roofs on their older buildings. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If you look after a building such as Mill Chase Academy, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

Different roofs, different checks
Inverted and paved roofs
We will tell you if your inverted or paved roof isn’t suitable.
Green and ballasted roofs
Testing before planting or ballast goes on is simpler.
DIY checks: what’s safe
A DIY look is useful, but it is not a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry, as it helps us focus the survey.
Passfield: your questions answered
Do you cover Passfield?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Is my home in Passfield listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a 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.
Is my roof suitable for ELD?
ELD doesn’t suit every roof. Some membranes conduct electricity and some roofs lack the layer the test needs. We will tell you if yours is not suitable before testing.
Will you check the loft?
Where it is relevant to the survey and there is safe access, yes. Please clear anything stored under the hatch, and if the loft cannot be reached safely, the report says so.
Which days do you carry out surveys?
We survey on any day from Monday to Sunday, during the day. Let us know your preferred days when booking.
How long does electronic leak detection take?
It depends on the size of the roof and its build-up. We’ll give you an idea when we quote.
How do I book a survey in Passfield?
Just call 07833 053749 or use the contact form. We will ask a few questions, confirm the price and agree a date, weekday or weekend.
What we are asked to look at in Passfield
A breach can be left during installation. ELD on a new roof can show holes before they cause leaks.
It’s worth booking a survey if you’ve seen:
- Patched roofs that still leak
- Breaches around outlets and penetrations
- Leaks through a covered membrane
- Gaps at membrane joints
For landlords with property near Liphook station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
What to check before booking
- Which limits apply to the survey
- Whether the loft space is looked at, where there is one
- Whether any drone flown is registered with the CAA
- Whether VAT is in the quoted price
