About electronic leak detection in Portsmouth
We carry out electronic leak detection on flat roofs in Portsmouth and across London and South East England. A visit typically takes a length of time set by the roof’s area and construction, which we’ll explain when we quote. Every roof is quoted on its size and build-up. You get a written report with photos. We survey roof terraces and balconies, liquid-applied waterproofing and commercial flat roofs, and people most often book us about leaking laps in the waterproofing and repairs that haven’t stopped the leak.
The visit typically starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. All told, expect a time that depends on the size of the roof and how it’s built, which we set out in the quote.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Prices in Portsmouth
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 safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.

Electronic leak detection across Portsmouth: local notes
Portsmouth has flat roofs of every size. The usual signs are standing water, blisters, splits and lifting edges, wherever the roof is in Portsmouth.
Our area covers London and South East England, including Portsmouth. London and South East England have homes from every era, from period terraces to post-war new towns and new estates. Parts of Portsmouth are on or near the coast, where roofs face more wind and more salt in the air than inland. Salt is hard on nails, clips and metal flashings, and strong wind lifts anything already loose.
Portsmouth: Take a building like Manor Infant School: a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail. For landlords with property near Fratton station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
What this survey cannot tell you
No survey can tell you everything, and we’d rather be clear about that before you book. Bear these in mind:
- Carrying out the repair work
- Some conductive membranes
- Parts of the roof covered by fixed equipment
Roof by roof
Inverted and paved roofs
A terrace or paved roof hides the waterproofing. Suitability depends on the layers.
Single-ply membranes
Single-ply can be punctured by tools or fixings. Testing helps find them.
Why roofs fail
When the membrane is buried, holes can’t be seen at all. Electronic methods can help on some of these roofs, depending on the build-up.
Most people get in touch after spotting one of these:
- Failed seams and laps
- Repairs that haven’t stopped the leak
- Damage from equipment installers
- Leaks under green or ballasted roofs
What happens if roof problems are left?
Water trapped under a membrane can soak insulation and decking. Locating it early helps limit the damage.
What to check before booking
- Their insurance cover
- Whether the inside of the roof is included
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Their report turnaround times
Useful tips for Portsmouth property owners
Here are a few things we’d tell any owner:
- Don’t leave water getting in
- Avoid repeated repairs without finding the cause
- Record dates and spots where water appears
- Tell us about the membrane and build-up if you know it
Once repairs are made, the roof can be tested again if you want to check them, where the roof still suits the method.
Limit foot traffic on flat roofs. Many breaches come from foot traffic.
Common questions in Portsmouth
Do I have to be there for the survey?
Not necessarily. An outside-only look can be arranged beforehand, but anything inside needs someone there to give access.
How many surveys have you done?
More than 5,000 surveys over 20+ years.
Does ELD work under paving or planting?
It can be possible, depending on the roof. What sits on the membrane affects the method, so we check the build-up first.
How much does electronic leak detection cost?
We quote for each roof individually. Tell us about the roof and where it leaks, and ring 07833 053749 or drop us an email for a quote.
Can you survey in bad weather?
Some surveys depend on the weather more than others. Drones can’t fly safely in strong wind or heavy rain, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. If the conditions aren’t right, we will talk to you about another date.
Do you work in Portsmouth?
Yes. Our area covers London and South East England, Portsmouth included.
Do you test for asbestos?
No. We don’t sample or test for asbestos. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000.
