Electronic Leak Detection in Watermill
Electronic leak detection to pinpoint holes in flat roof membranes in Watermill. We’ve completed more than 5,000 surveys across London and South East England.

- New roofs to check before paving or planting
- Failed seams and laps
Why act early in Watermill
A visual inspection can miss tiny holes. ELD picks up breaches a visual check might miss, on suitable membranes. Older cottages and farmhouses around Watermill can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it is left.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Why book with us
- CAA-registered drone operator (Flyer ID and Operator ID)
- Two decades and more of roof surveys
- Covered by professional indemnity and public liability insurance

Electronic leak detection for homes and businesses in Watermill
Our ELD testing covers flat roofs in Watermill and the rest of London and South East England. Testing typically takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Electronic leak detection is quoted for your roof, because the method depends on the roof. You get a written report with photos. If you’ve noticed stains far from any visible defect and gaps at membrane joints, we can find out what’s behind it, whatever the roof.
In a village or hamlet like Watermill, flat roofs are normally on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: outlets, upstands, edges and the covering itself. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included when you book.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

What electronic leak detection looks like in Watermill
Watermill lies within about 3 miles of the sea, and being near the sea means more wind and salt than a roof inland would face. Salt in the air is hard on metal flashings and fixings, and wind catches any loose edge on a flat roof. Older houses across Sussex often have handmade clay tiles, and many have tile-hanging on their upper walls. Horsham stone slab roofs survive on some old Sussex buildings, alongside oast houses and timber-framed Wealden hall houses. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
Anyone responsible for a site like Bexhill High Academy will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

Do you need electronic leak detection in Watermill?
Flat roof membranes can be punctured by foot traffic, dropped tools or debris. Many are tiny but water still finds them.
Most people get in touch after spotting one of these:
- Holes left by work on the roof
- Repairs that haven’t stopped the leak
- New membranes needing a check before handover
- Breaches hidden under paving or planting
For landlords with property near Crowhurst station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Before you book any roof surveyor

- How they plan to inspect the roof safely
- Do they have a CAA Flyer ID and Operator ID for drone work?
- How long the report takes to arrive
What this survey cannot tell you
Some things can’t be seen without opening up the roof, and that sets some limits:
- Water entering through details rather than the membrane
- Repairing the breaches (that is for your roofer)
- Some conductive membranes

Testing before planting or ballast goes on is simpler.
Inverted and paved roofs
We’ll tell you if your inverted or paved roof is not suitable.
How it works
After the inspection, everything we found is written up in a report with photos. As for time on site, most surveys take longer on a large roof than a small one, with the construction of the roof playing a part too. Somewhere like Watermill needs a little journey planning: let us know about lanes, gates and parking. The roof is looked at from ground level, from windows, from the loft where there’s safe access and from the roof where it is safe.
- First, you tell us about the roof build-up and where water is showing.
- We confirm whether the roof is suitable for electronic testing.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
Preparing for the visit
- Buyers: confirm access with the estate agent or seller
- Have any questions written down, so nothing gets missed
- Leave a clear route to the loft
Booking a survey
Every survey is priced before it’s booked, so you know the cost up front. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, call 07833 053749 or send us an email.

Questions from Watermill
Does a conservation area affect roof work in Watermill?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Will you come out to Watermill?
Yes. Watermill is within the area we cover, which takes in towns, villages and rural addresses. We work right across London and South East England. Let us know about access, parking and anything unusual about getting there when booking.
Is my roof suitable for ELD?
It depends on the membrane and the build-up. Let us know what you know about the roof and we will check whether ELD will work.
What will the report tell me?
It sets out what we found, why it matters and what we recommend, with photographs throughout. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
Do you need to get into the loft?
Where it is relevant to the survey and there’s safe access, yes. A clear path to the hatch helps, and if the loft can’t be reached safely, the report says so.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
How long does electronic leak detection take?
Testing normally takes more time on a big roof than a small one, with the construction of the roof playing a part too.
