Southampton Electronic Leak Detection
A careful look at the flat roof membrane at your property in Southampton, and put it all in a written report with photos.
- Holes around roof penetrations
- Failed seams and laps
- A flat roof leak that can’t be traced
How electronic leak detection works in Southampton
Roofs covered with paving, ballast or planting need more thought. The layers on top can limit the methods we can use, and some may need lifting. We will discuss it with you when we quote. Any details of the build-up help, as they show what lies beneath the surface. We’ll tell you if the roof cannot be tested. If you’re worried about new membranes needing a check before handover and leaks that return after repairs, we can find out what’s behind it, whatever the roof.
In a place like Southampton, flat roofs cover everything from garages and extensions to shops, offices and blocks. Typical lives vary: felt often around 15–20 years, EPDM around 30–50, GRP up to about 30. Ponding, blistering, splits and tired upstands are the usual signs of age. Those are typical ranges, and workmanship matters as much as the material.
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.

Why act early in Southampton
Repairs in the wrong place leave the leak in place. ELD shows the actual breach points. A small defect on a roof in Southampton seldom stays small: a slipped slate or cracked ridge lets in water, water rots battens, and more slates or tiles follow. Dealing with it early is usually the cheaper route.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.

Your questions about electronic leak detection in Southampton
Do you look at commercial flat roofs near Southampton, such as hotels?
Yes, commercial buildings, hotels included, are part of the work. Roof access is agreed with the building manager or owner beforehand.
Does being near the coast affect roofs in Southampton?
Yes, coastal weather is harder on roofs: there is more wind, and more salt in the air. Exposed details such as ridges, verges, flashings and metal fixings are the ones to watch.
How do I book a survey in Southampton?
To book, phone 07833 053749 or drop us an email and tell us the address and what you’d like to know. We’ll confirm the price and agree a day with you.
Which method do you use?
The method is chosen to suit the roof. Low-voltage testing normally needs a wet surface, while high-voltage testing needs a dry, exposed membrane.
Can you inspect my roof with a drone?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.
What happens next?
You receive the written report by email, with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Will you go up on the roof?
Only when it is safe. Safe viewpoints, the roof space and a drone where it applies cover most of what’s needed.
Local flat roofs in Southampton
Southampton is within about 2 miles of the coast, where sea air brings more salt and stronger wind than inland. On a flat roof near the sea, edge trims and upstands take the brunt of the wind, and metal parts corrode faster. There are several hotels within about a mile and a half of Southampton. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
If you run a business near Marlands Shopping Centre, flat roofs over shops and units are easy to forget until water comes through a ceiling. Southampton Tudor House and Garden lies about 1.4 miles south, so building around Southampton goes back a long way. On a period home nearby, any flat roof is likely to be a later addition with its own lifespan. Anyone responsible for a site like Bevois Town Primary School will know that a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.
Southampton is in England. Wherever you are in Southampton, we can come and survey your property, on a weekday, Saturday or Sunday. We cover towns and villages across the surrounding area, from the larger towns to small villages.

When you need someone else
It’s a careful look at the flat roof membrane, not the whole story. The main limits are:
- Leaks from walls, copings or rooflights
- Moisture spread under the membrane
- Fixing the holes we find
Not sure which survey suits your roof? You can call 07833 053749 or send us an email and we will tell you. What our survey covers.
What this survey covers
- Liquid-applied waterproofing
- Roof terraces and balconies
- Commercial flat roofs
- Single-ply roofs
- Green roofs
- Flat roof membranes
What a survey costs
To price your survey, we look at:
- Building height and the viewpoints available
- If the survey needs thermal imaging or a drone
- Commercial roofs and larger buildings
- Roof area
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before you book.
Getting in touch
These details help when you get in touch:
- Any photos you have, taken from the ground or a window
- Any stains, drips or damp patches you’ve seen indoors
- How the loft is reached, if there is one
- When you need the report by
If you are buying, it is useful to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply ring 07833 053749 or use the contact form whenever suits you.
What we do, step by step
Every roof is different, but as a rough guide the survey takes as long as needed for the size of the roof and how it’s built, which we’ll explain when we quote. You are welcome to ask questions while we’re there. If the property is near the centre of Southampton, let us know about car parks or permit rules nearby. We’ll want to see the loft, if there is one, and any ceiling or wall showing damp. Outside, we work round the building to find the safe viewpoints.
- You let us know about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photos shows where each breach is.
Preparing for the visit
- Let us know where we can park nearby
- Move anything stored under the loft hatch
- Make a note of anything you’d like us to look at
How to book
If you have photos of the roof, send them over. Pictures from the ground or a window are fine. To send them or to book, ring 07833 053749 or email us.

Should I look at the roof myself first?
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.
Your own check is a good start, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight.
How the survey changes by roof type
EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but punctures and seam failures still happen.
Green and ballasted roofs
Green roofs and ballasted roofs cover the waterproofing. Some methods can work through these layers but it depends on the layers.
