Electronic leak detection in Hill Brow: what you get
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It works with an electrical current which can only get through the membrane at a breach. It can find holes too small to spot by eye, so your roofer can repair them. The results come in a report with photos. Typical surveys look at leaks under green or ballasted roofs and gaps at membrane joints, across single-ply roofs, green roofs and liquid-applied waterproofing.
In a small place like Hill Brow, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Older felt roofs, often 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 usually the first part of a flat roof to go.
Nothing in the report is left vague: if work is needed, the report says so clearly, and where it can wait, that’s said too.

Tips that help
Nothing here needs a ladder. Our suggestions:
- Record dates and spots where water appears
- Find the breach before more patching
- Get leaks traced quickly
- Use boards when working on the roof
Wet insulation may need attention after a leak. Your roofer can advise on that and other checks can help judge it.
Keep outlets and gutters on flat roofs clear. Water that sits on the roof finds breaches faster.
FAQs for Hill Brow
How do I find out if my home in Hill Brow is listed?
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 Hill Brow in the area you cover?
We do. The survey and report are the same in Hill Brow as anywhere else, and visits run on weekdays and weekends.
Can you survey in bad weather?
Some surveys depend on the weather more than others. Drones can’t fly safely in strong wind or heavy rain, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. We will rearrange with you if the weather isn’t right.
Will you repair the leak?
No. ELD is testing only. You get the breach locations with photos for your roofer to repair.
Are you structural engineers?
No. Visible signs like deflection or sagging are recorded, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
When does the report arrive?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. All of them come by email.
Do you survey roofs on blocks of flats?
Yes, once access has been agreed. The roof of a block or converted house is often shared, so the building owner or managing agent needs to agree access. We can only inspect what we are given access to.
Why act early in Hill Brow
Some flat roof leaks come from walls or details. ELD helps rule the membrane in or out, so other causes can be checked. Matching old materials, such as handmade tiles or stone slates, can take time to source. That’s one more reason to find defects before they become urgent.
The cost of a survey depends on the roof: its size, its height, how many sections it has 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 Hill Brow
Thatch survives on some older buildings in Hampshire’s villages. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. Older buildings may be listed or sit in a conservation area. Historic England’s list shows listed buildings, and the council can say whether a street is in a conservation area. In either case, a change of roofing material may need consent.
For site and facilities teams at buildings such as Liss Junior School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. Take an older house close to Rake Mission Church: the flat roofs on later extensions tend to wear out long before the main roof. If you own a rental within reach of Liss station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

What affects the cost of electronic leak detection
Prices vary from roof to roof, and it comes down to:
- The shape of the roof and its details
- Whether it’s a home or a commercial building
- The size of the roof
- The height of the building and how the roof can be seen safely
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the price for your roof before booking.
What we need to know
You do not need to know any roofing terms. It’s enough to let us know:
- The reason for the survey, like buying, a leak or storm damage
- The type of building and roof, such as pitched or flat
- Any marks or damp showing indoors
- Pictures from the garden or a window, if you have them
Our phone lines are open seven days a week, including Saturdays and Sundays. For a price or to book, ring 07833 053749 or drop us an email.
How it works
We do not take risks to get a closer look. We inspect what can be seen safely, and anything we can’t see is noted in the report. Most visits take a time that depends on the membrane area and the build-up, which we set out in the quote. Somewhere as small as Hill Brow, access is frequently the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- 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.
- You receive the results to pass to your roofer.
Getting ready for the survey
- Keep pets in another room
- Make sure we can get to the back of the property
- Show us where any leaks or stains appear
Booking a survey
Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, call 07833 053749 or email us.
Advice
When you need someone else
No survey can tell you everything, and we’d rather be clear about that before booking. Bear these in mind:
- Build-ups without a suitable layer below
- Areas we can’t reach or that can’t be tested
- Leaks from walls, copings or rooflights
If in doubt, ring 07833 053749 or use the contact form and we will recommend the right survey before booking. What a survey covers and does not.
