Electronic leak detection in Swanwick
A leak in a flat roof often shows up a long way from where the water gets in. So the stain inside rarely sits under the hole. ELD tests the waterproofing directly, to find where it has been breached. We test and report and leave the repair to your roofer. On a suitable roof, it takes the guesswork out of finding the hole. We then send you the results in a written report. We survey single-ply roofs, liquid-applied waterproofing and roof terraces and balconies, and common reasons people get in touch are leaks through a covered membrane and repairs that haven’t stopped the leak.
In a small place like Swanwick, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Older felt roofs, often around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. On an exposed roof, the edges tend to go first.
Pictures do a lot of the work in our reports, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

What you can safely check yourself
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Share it with us as you book and it will help the survey.
Swanwick: your questions answered
Do you cover smaller places like Swanwick?
Yes, we do. We cover the whole of London and South East England, and smaller places are part of that. Longer journeys are simply planned ahead of time.
Does being near the coast affect roofs in Swanwick?
Generally, yes: wind and salt air take more of a toll near the sea. Exposed details such as ridges, verges, flashings and metal fixings are the ones to watch.
How quickly is the report sent?
Report times are set by the package. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. If you have a deadline, such as an exchange date, let us know when you book.
How does ELD work?
The waterproofing membrane normally stops an electrical current, but a hole lets it through. That lets us find breaches that are too small to see.
How experienced are you?
Over 20 years and more than 5,000 surveys, across London and South East England.
What’s in the survey report?
It works through the roof part by part, in writing and with photos, and ends with what we recommend. The most urgent items are made clear.
How do I arrange electronic leak detection in Swanwick?
To book, call 07833 053749 or drop us an email and let us know the address and what you’d like to know. We’ll confirm the price and agree a day with you.
Practical tips
You do not need to be a roofer to help. Here’s what helps most:
- Act on new leaks promptly
- Find the breach before more patching
- Keep foot traffic on flat roofs to a minimum
- Test new membranes before covering them
The report records each breach location with photos. Pass it to your roofer to repair the breach points.
Clear flat roof outlets regularly. Water that sits on the roof finds breaches faster.

What else we do in Swanwick
Electronic leak detection in Swanwick: local notes
Swanwick is within about 3 miles of the coast, so there is more wind and more salt in the air than further inland. Salt in the air is hard on metal flashings and fixings, and wind catches any loose edge on a flat roof. Thatch survives on some older buildings in Hampshire’s villages. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops.
For an older house near a landmark like Church of St Paul, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. For landlords with property near Bursledon station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. Take a building like Sarisbury Church of England Junior School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

What happens on the day
You don’t need to do much on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we will take it from there. The survey itself takes a time that depends on the membrane area and the build-up, which we set out in the quote. In a small place like Swanwick, access is normally the main thing to plan. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Weekday and weekend visits are available.

- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.

Why act early in Swanwick
Not every leak is in the membrane. ELD helps rule the membrane in or out so attention can go to the right place. Older and listed buildings around Swanwick may need consent and matching materials for repairs, so a defect found early gives time to plan the work properly.
To find out what your survey will cost, call 07833 053749 or send us an email with the address and some details. The price is agreed before a date is set.
