Poynings Electronic Leak Detection
Electronic leak detection to pinpoint holes in flat roof membranes in Poynings. We have completed more than 5,000 surveys across London and South East England.
- Failed seams and laps
- Damage from equipment installers
- Holes around roof penetrations
What you can safely check yourself
A lot can be seen from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
A DIY look is useful, but it is not a survey. From ground level, valleys, flashings and the backs of chimneys are frequently out of sight.
How electronic leak detection works in Poynings
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small electrical current that passes through the membrane only where there’s a breach. That lets us locate holes that are too small to see, so your roofer can repair them. The results come in a report with photos. We survey liquid-applied waterproofing, green roofs and commercial flat roofs, and the problems we are asked to look at most are stains far from any visible defect and damage from equipment installers.
In a village or hamlet like Poynings, flat roofs are usually 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 booking.
The report doesn’t just list problems. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

Electronic leak detection around Poynings
Poynings is within about 5 miles of the coast, and being near the sea means more wind and salt than a roof inland would face. 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. Some old buildings in Sussex have Horsham stone slab roofs. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
Take an older house close to The Church of the Holy Trinity: the joins between later flat roofs and the old walls are where problems normally start. If you let a flat or house near Hassocks station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Poynings is about 4 miles north of Brighton and Hove, in West Sussex. Wherever you are in Poynings, we can come and survey your property. Across West Sussex, we cover Poynings and the places around it.

Rented homes, blocks and businesses
Landlords and letting agents in Poynings book surveys as well as householders. A photo-illustrated written report gives you a clear record of the flat roof membrane.
An agent can book and manage the survey for a landlord, and the report can go to both. Access is agreed with the tenant beforehand.
How the survey works
We do not take risks to get a closer look. We inspect whatever is safely visible, and if part of the roof cannot be seen, the report says so. The survey usually takes a time that depends on the membrane area and the build-up, which we set out in the quote. For a village or hamlet like Poynings, the journey is planned ahead of time: let us know about lanes, gates and parking. The roof is looked at from ground level, from windows, from the loft where there is safe access and from the roof where it’s 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.
- We pick the low-voltage or high-voltage method that suits the roof.
- The roof is tested and any breaches are located.
- The breaches are recorded with photos in a report for your roofer.
Getting ready for the survey
- Dig out any old roof reports or invoices
- Jot down any questions you want answered
- Let us know about any leaks, stains or damp patches you know of
Book a survey
Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, phone 07833 053749 or drop us an email.

What affects the price in Poynings
All our prices include VAT. What changes the price is:
- Features like valleys, chimneys, dormers and parapets
- Commercial roofs and larger buildings
- The height of the building and how the roof can safely be seen
- The size of the roof
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You will know the figure before booking.
Getting in touch
The more you tell us, the easier it is to price the survey. When you contact us, tell us:
- Where any leaks, stains or damp patches show inside
- Any photos you have, taken from ground level or a window
- The style of property, from a terrace to a block
- Access details, such as a loft hatch or a shared roof
We confirm the price for the job before booking, 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, phone 07833 053749 or email us.
Why it is worth a survey now in Poynings
Opening up a roof to hunt for a leak is disruptive. ELD aims to locate the breach first, so the repair can be targeted. Where a roof is exposed, as many are in small places like Poynings, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.

When to book a survey in Poynings
When the membrane is buried, holes can’t be seen at all. ELD can work on some covered roofs though it depends on the layers.
People usually book a survey when they’ve noticed something like this:
- Gaps at membrane joints
- Waterproofing to test before it’s covered
- Holes around roof penetrations
- Holes left by work on the roof
With Portslade Manor about 3.7 miles south, the area around Poynings has a long history. On a period home nearby, any flat roof is likely to be a later addition with its own lifespan.

Your questions about electronic leak detection in Poynings
Is the coastal weather around Poynings hard on roofs?
Generally, yes: wind and salt air take more of a toll near the sea. Ridges, verges, flashings and fixings are where it typically shows.
Is my home in Poynings listed or in a conservation area?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
What will the report tell me?
You get our findings in writing, part by part, with photos, and ends with what we recommend. Points are put in order of urgency where relevant.
When does the report arrive?
Report times are set by the package. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. Mention any deadline when you book.
Do you need to get into the loft?
If it is needed and safe to reach, yes. We look for staining, damp, daylight and signs of movement, as far as the space allows.
Does this replace a RICS home survey?
No. This is a survey of the roof only, so it’s not a RICS Level 2 or Level 3 survey. Many buyers have both.
Do you use drones?
Yes, where it is applicable. Flights depend on the weather on the day and airspace rules, including flight restriction zones near airports. We hold a CAA Flyer ID and Operator ID.
