Electronic leak detection in Witherenden Hill: what you get
Not every flat roof suits electronic testing. Certain membranes conduct electricity and some roofs don’t have a suitable layer beneath the membrane. We will say if ELD will not work on your roof at the start. Telling us what you know about the roof’s membrane and layers helps, including drawings, specifications or the roofer’s paperwork. It saves a wasted visit. We survey liquid-applied waterproofing, commercial flat roofs and flat roof membranes, and the problems we’re asked to look at most are repairs that haven’t stopped the leak and leaks through a flat roof with no obvious cause.
Somewhere as small as Witherenden Hill, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access in advance. If there are outbuildings or garages with flat roofs, mention them when you book.
We keep jargon out of it: if work is needed, the report says so clearly.

Signs you need electronic leak detection in Witherenden Hill
Work on the roof can damage a membrane. Fixings, equipment and foot traffic can leave small holes.
We are often asked to look at:
- Leaking laps in the waterproofing
- Leaks through a covered membrane
- Holes around roof penetrations
- Water coming in under a flat roof
If you let a flat or house near Stonegate station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

FAQs for Witherenden Hill
Does a conservation area affect roof work in Witherenden Hill?
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 Witherenden Hill?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Is this a RICS survey?
No. This is a survey of the roof only, and it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
How quickly is the report sent?
Each package has its own report time. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. Mention any deadline as you book.
How do you choose the testing method?
It depends on the membrane and the build-up. Low-voltage testing normally needs a wet surface, while high-voltage testing needs a dry, exposed membrane.
Is it a structural engineer’s report?
No. Visible signs such as deflection or sagging are recorded, but we don’t provide calculations or an engineer’s opinion. The report will say if you need an engineer.
How many surveys have you done?
We have more than 20 years’ experience and have carried out more than 5,000 surveys across London and South East England.

What else we do in Witherenden Hill
Local flat roofs in Witherenden Hill
Many older homes in Sussex have handmade clay tiles and tile-hung walls. Some old buildings in Sussex have Horsham stone slab roofs, and oast houses and timber-framed Wealden hall houses are part of East Sussex’s older buildings. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. With Bateman's about 2 miles south-east, Witherenden Hill sits in an area with a long building history. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material.

What we do, step by step
On the day, we start by asking what you’ve noticed and what you’d like to know. We then inspect everything that can be seen safely, from ground level, from windows, in the roof space and by drone where it applies. Most surveys take more time on a big roof than a small one, with the construction of the roof playing a part too. In a small place like Witherenden Hill, access is typically 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 start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Preparing for the visit
- Clear the way to the loft hatch
- Let us know about any leaks, stains or damp patches you know of
- Have any questions written down, so nothing gets missed

Roof by roof
Bituminous membranes
Older felt roofs often have seams and patches where breaches occur. Testing depends on the roof.
Liquid-applied waterproofing
Testing a liquid-applied roof depends on what’s beneath the coating.
Why act early in Witherenden Hill
Chasing a leak again and again is frustrating. A clear record of where the breaches are helps break that cycle. Where a roof is exposed, as many are in small places like Witherenden Hill, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the price for your roof before booking.

Before and after the survey
Nothing here needs a ladder. Our suggestions:
- Act on new leaks promptly
- Stay off the flat roof unless needed
- Consider ELD before paving or planting goes on
- Keep a note of leaks after rain
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
ELD before paving, ballast or planting goes on is worth considering. It’s easier to find holes before more layers are added.
Should I look at the roof myself first?
You can learn a lot from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That’s where a survey comes in.
