How electronic leak detection works in Waterhall
ELD can be carried out in more than one way. Low-voltage methods usually need a wet roof surface, while high-voltage testing needs a dry, exposed membrane. The right method depends on the membrane and the build-up of the roof, and we will explain our choice. We will say if your roof doesn’t suit either method at the outset. Typical surveys look at failed seams and laps and holes left by work on the roof, on roof terraces and balconies, commercial flat roofs and single-ply roofs.
Somewhere as small as Waterhall, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them when booking.
We keep jargon out of it: where something needs attention, it says so plainly, along with how urgent it is.

Tips that help
From years of surveys, a few habits stand out:
- Check new waterproofing before handover
- Do not let outlets block
- Act on new leaks promptly
- Stay off the flat roof unless needed
Questions about the results are welcome. We can talk you through the findings.
Limit foot traffic on flat roofs. Many breaches come from foot traffic.
Questions from Waterhall
Does a conservation area affect roof work in Waterhall?
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 roofs near the sea, like those around Waterhall, take more of a battering?
Near the coast, roofs face more wind and more salt than further inland. Salt is hard on nails, clips and metal flashings, while strong wind lifts anything already loose.
Do you survey on Saturdays and Sundays?
We carry out surveys on weekdays, Saturdays and Sundays. To arrange a date, ring 07833 053749 or drop us an email.
Will you repair the leak?
No. We test the membrane and report. The report shows where each breach is for your roofer to repair.
How do I arrange electronic leak detection in Waterhall?
To arrange a survey, phone 07833 053749 or email us with the address, the type of property and what’s prompted the survey. We will confirm the price and find a day that suits.
Does electronic leak detection work on all membranes?
Not every roof is suitable. Some membranes conduct electricity, and some build-ups lack a suitable layer below. We’ll tell you if yours isn’t suitable before testing.
Is it a structural engineer’s report?
No. Our survey isn’t a structural engineer’s report, and it does not include calculations. If we see signs that need an engineer’s opinion, we’ll recommend one.
What happens on the day
Every visit follows the same pattern: we hear what you’ve seen, look at the roof from every safe viewpoint, photograph what we find and record our findings for the written report. Most visits take as long as needed for the size of the roof and how it’s built, which we set out in the quote. In a hamlet or village like Waterhall, a postcode does not always lead to the right gate, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- You tell us about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photos shows where each breach is.
How to prepare
- If it is not your property yet, arrange access through the agent
- Jot down any questions you want answered
- Find any records of previous roof work
Getting a price
We confirm the price for your survey before booking, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. To book, call 07833 053749 or drop us an email.
Related advice
How we price electronic leak detection
The price reflects the time and kit the roof needs. The main factors are:
- How complicated the roof is, with its valleys, chimneys and parapets
- Any need for thermal images or a drone flight
- Commercial roofs and larger buildings
- Extensions, dormers and garages with roofs of their own
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before you book.
What we need to know
Here’s what helps us most when you get in touch:
- Any deadline, like an exchange date
- Where any leaks, stains or damp patches show inside
- What kind of property and roof it is
- Why you want a survey: buying, a leak, a storm or new work
If you have photos of the roof, send them over. Take them safely from ground level or a window; never climb up to get a better view. To send them or to book, phone 07833 053749 or drop us an email.

What this survey can’t tell you
Our findings are based on what we can see safely on the day, so there are some things a survey cannot cover:
- Areas we can’t reach or that cannot be tested
- The extent of water in the insulation
- Water entering through details rather than the membrane
If you are not sure which survey you need, phone 07833 053749 or drop us an email and we will give you a straight answer before booking. What our survey covers.
What we look at
- Green roofs
- Flat roof membranes
- Liquid-applied waterproofing
- Roof terraces and balconies
- Commercial flat roofs
- Single-ply roofs
Should I look at the roof myself first?
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Share it with us as you book.
Look up at the roof after a storm, from the ground: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
Roof by roof
Single-ply membranes
Punctures from foot traffic and equipment are common on single-ply roofs. Testing helps find them.
Liquid-applied waterproofing
Liquid waterproofing has no laps, but can still have thin spots or holes. Suitability for ELD depends on the system.
Flat roofs in Waterhall
The coast is about 3 miles or less from Waterhall, 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. Handmade clay tiles and tile-hung upper walls are typical of older Sussex houses. Some old buildings in Sussex have Horsham stone slab roofs. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops.
Preston Manor & Gardens, about 2 miles south, is one of the historic houses in the wider area around Waterhall. If your home is older, its flat-roofed extension or dormer may be on its second or third covering. For landlords with property near Preston Park station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. Anyone responsible for a site like Westdene Primary School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
