Electronic leak detection in Dukes Green: what you get
ELD finds breaches in the membrane but not every way water gets in. Water coming through walls, copings, rooflights or plumbing won’t show on the test. We’ll tell you if we think the leak is coming from somewhere else. The test shows breaches in the membrane, not water coming through masonry or around frames. The report makes clear what was and wasn’t tested. We will point you to the likely next step. We survey flat roof membranes, green roofs and roof terraces and balconies, and the problems we are asked to look at most are new roofs to check before paving or planting and damp inside with no sign on the roof.
Somewhere as small as Dukes Green, flat roofs tend to be on extensions, garages and converted outbuildings. 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.
We keep jargon out of it: where something needs attention, it says so plainly, and where it can wait, that’s said too.

Should I look at the roof myself first?
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
Landlords, agents and block managers in Dukes Green
If the property is let, the agent or a tenant can let us in, at a time agreed beforehand. We survey on weekdays, Saturdays and Sundays, which helps when tenants work during the week.
An agent can book and manage the survey for a landlord, with the report sent to whoever needs it. Access is agreed with the tenant in advance.
Tips from our surveys
Most of what helps is simple and safe from ground level. Our suggestions:
- Do not let outlets block
- Consider ELD before paving or planting goes on
- Note where leaks show inside and when
- Tell us about the membrane and build-up if you know it
If water has been getting in, insulation under the membrane may be wet. Your roofer can advise on that and other checks can help judge it.
Ask trades working on the roof to protect the membrane when they work up there. Have the roof looked at after other work.
When to book a survey in Dukes Green
On a flat roof, water spreads under the waterproofing. The stain inside can be far from the hole which makes it hard to find by looking.
We are often asked to look at:
- Holes around roof penetrations
- New roofs to check before paving or planting
- Punctures from foot traffic or tools
- Breaches hidden under paving or planting
Historic houses such as Alfriston Clergy House, about 0.5 miles north-east, show how far back building around Dukes Green goes. Older homes nearby may have later flat-roofed extensions or dormers, often re-covered more than once.
Questions to ask before you book
- Whether you get a written report with photos
- What the survey won’t cover
- Whether they hold professional indemnity and public liability insurance
- What happens after the report arrives
FAQs for Dukes Green
Is the coastal weather around Dukes Green hard on roofs?
It can do. Within about 3 miles of the sea, as Dukes Green is, metal fixings wear faster and gales find any loose ridge or slate.
Does a conservation area affect roof work in Dukes Green?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
How experienced are you?
More than 5,000 surveys over 20+ years.
Can you inspect my roof with a drone?
Yes, where it is applicable. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and every flight depends on the airspace and the weather.
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, which shows us where the hole is.
Do you carry out surveys on Saturdays and Sundays?
Surveys run on weekdays, Saturdays and Sundays. To find a day that suits you, phone 07833 053749 or drop us an email.
Do you survey roofs on blocks of flats?
Yes, as long as access is agreed. Roofs over flats are often shared, so the freeholder or managing agent needs to agree access. We inspect only the parts we’re allowed to reach.
How it works
On the day, we begin with a quick chat about the roof and anything that’s worrying you. We then inspect everything that can safely be seen, from ground level, from windows, in the loft space and by drone where applicable. The survey usually takes a time that depends on the membrane area and the build-up, which we set out in the quote. Cottages and farmhouses around Dukes Green often have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can safely be seen, and anything we can’t see is noted.
- First, you tell us about the roof build-up and where water is showing.
- We confirm whether the roof is suitable for electronic testing.
- We pick the low-voltage or high-voltage method that suits the roof.
- We test the membrane and find where current is passing through it.
- You get a report showing where each breach is, for your roofer to repair.
Getting ready for the survey
- Show us where any leaks or stains appear
- Jot down any questions you want answered
- Let us know where we can park nearby
Book a survey
Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. For any other survey, just ring 07833 053749 or use the contact form when you’re ready.

Prices for electronic leak detection in Dukes Green
A few things affect what a survey costs:
- The roof’s overall size
- How many separate roofs there are, such as extensions, dormers and garages
- If the survey needs thermal imaging or a drone
- How complicated the roof is, with its valleys, chimneys and parapets
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before you book.
What we need to know
Getting the details right at the start saves time. It is useful to include:
- What made you get in touch
- Your postcode, so we can check access and travel
- The type of building and roof, such as pitched or flat
- Any deadline, like an exchange date
Most bookings start with a short call: phone 07833 053749 or send us an email and we will ask a few questions about the roof. The price is agreed before a date is set.
Electronic leak detection around Dukes Green
The coast is about 3 miles or less from Dukes Green, where sea air brings more salt and stronger wind than inland. Wind can catch loose edges and trims on a flat roof, and salt air is hard on metal trims, flashings and fixings. Many older homes in Sussex have handmade clay tiles and tile-hung walls. A few old Sussex buildings still carry heavy Horsham stone slabs, and the county’s older buildings include oast houses and Wealden hall houses. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops.
Take an older house close to The Parish Church of St Michael the Archangel: the flat roofs on later extensions tend to wear out long before the main roof. Anyone responsible for a site like Alfriston School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
