Roof by roof
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer but holes and thin areas can occur. Suitability for ELD depends on the system.
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing, which affects testing.
About our electronic leak detection in South Down
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small 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 knows exactly where to repair. You get a report with photographs of each breach found. Common reasons to book are leaks showing away from the breach and new roofs to check before paving or planting, across commercial flat roofs, roof terraces and balconies and flat roof membranes.
In a village or hamlet like South Down, flat roofs are typically on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included when you book.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

What else we do in South Down
Rented homes, blocks and businesses
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait, which helps with budgets and planning.
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work.
What a survey costs
Every roof is different, so prices are confirmed before you book. These are the things that affect it:
- Whether thermal imaging or a drone is needed
- Features like valleys, chimneys, dormers and parapets
- Whether it is a home or a commercial building
- The size of the roof
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 survey before booking.
What to tell us when you get in touch
Here’s what helps us most when you contact us:
- The type of building and roof, such as pitched or flat
- Where water is showing inside, if it is
- Your postcode, so we can check access and travel
- What made you get in touch
We survey roofs on weekdays, Saturdays and Sundays. To arrange a day that suits you, phone 07833 053749 or email us.
Tips from our surveys
There is plenty you can do without going near the roof. Here’s what helps most:
- Keep a note of leaks after rain
- Find the breach before more patching
- Clear flat roof outlets regularly
- Have roof specifications to hand
Wet insulation may need attention after a leak. Your roofer can advise on that, and moisture readings can help.
ELD before paving, ballast or planting goes on is worth considering. It is easier to find holes before more layers are added.
South Down: your questions answered
Do you carry out roof surveys in South Down?
Yes, South Down is one of the places we work. The survey and report are the same in South Down as anywhere else, and visits run on weekdays and weekends.
Is my home in South Down listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
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 recommend a specialist asbestos surveyor checks them before they’re disturbed.
What do I do with the report?
You will receive the report by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
Do you take photos of the roof?
Yes, plenty. Each finding is shown in a picture where possible.
What is electronic leak detection?
ELD passes a small electrical current across the roof to locate holes in the membrane. The current only gets through where the membrane is breached so we can pinpoint it.
Is my roof suitable for ELD?
That depends on the roof’s membrane and layers. Tell us what you know about the roof and we’ll check whether ELD will work.
Why act early in South Down
Not every leak is in the membrane. Testing shows whether the membrane is breached so attention can go to the right place. In a small place like South Down, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
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.
Why us?
- Professional indemnity and public liability insurance
- Customer satisfaction of 98%
- More than 5,000 surveys completed

Local flat roofs in South Down
Some Hampshire villages still have thatched roofs. 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. If your home is older, it is worth knowing whether it is listed or in a conservation area before planning roof work. Changes that affect a listed building’s special interest need listed building consent, and councils can also use Article 4 directions to control changes in conservation areas.
If you let a flat or house near Shawford station, the flat roof over a let home is worth a look before it becomes a tenant complaint. For site and facilities teams at buildings such as Twyford St Mary's Church of England Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If you live in an older home near Church of All Saints, flat-roofed rear additions and dormers added over the years are worth checking.

The survey, step by step
The visit has one job: to see as much of the flat roof membrane as can safely be seen and record it clearly. Everything we note and photograph goes into the written report. It normally takes a time that depends on the membrane area and the build-up, and we’ll give you a guide when quoting. In a small place like South Down, access is usually the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- The roof is assessed to see if electronic testing will work on it.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- You get a report showing where each breach is, for your roofer to repair.
Before we arrive
