Electronic leak detection in Haslar: what you get
Electronic leak detection works on many flat roof membranes over offices, units, blocks of flats and homes. It helps trace a leak you already have or check a new membrane before handover. Each roof is quoted on its size and build-up. We can test on weekdays and at weekends when conditions allow. Just ask about your roof. Typical surveys look at gaps at membrane joints and a flat roof leak that can’t be traced, on green roofs, liquid-applied waterproofing and roof terraces and balconies.
In a small place like Haslar, 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. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
Where we cannot see part of the flat roof membrane, the report says so. That way, it’s clear what was covered and what wasn’t, and what we’d suggest next.

Signs you need electronic leak detection in Haslar
A breach can be left during installation. ELD on a new roof can show holes before they cause leaks.
A survey can pick up problems such as:
- Holes left by work on the roof
- Water coming in under a flat roof
- Leaks through a covered membrane
- Stains far from any visible defect
If you let a flat or house near Portsmouth Harbour station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Questions to ask before you book
- Whether you can ask questions once you have the report
- Will the report include photos?
- Whether VAT is in the quoted price
- How much experience they have with roofs like yours
Electronic leak detection around Haslar
Haslar is within about 1 mile of the coast, so there’s more wind and more salt in the air than further inland. On a flat roof near the sea, edge trims and upstands take the brunt of the wind, and metal parts corrode faster. Thatch survives on some older buildings in Hampshire’s villages. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For an older house near a landmark like St Francis, the joins between later flat roofs and the old walls are where problems typically start. For site and facilities teams at buildings such as Haselworth Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Haslar is about 2 miles south-east of Gosport, in Hampshire. We provide electronic leak detection for homes and businesses in Haslar and the surrounding area. Across Hampshire, we cover Haslar and the places around it.

Leave it or get it looked at?
Testing a new membrane before it is covered is easier than tracing a leak later. Once layers are added, finding a breach is harder. In a place like Haslar, a barn or garage roof left to fail puts whatever is inside at risk. A quick look before winter can save a lot.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.

Your questions about electronic leak detection in Haslar
Does being near the coast affect roofs in Haslar?
Yes, coastal weather is harder on roofs: there is more wind, and more salt in the air. Ridges, verges, flashings and fixings are where it usually shows, and Haslar is within about 1 mile of the coast.
Will you come out to Haslar?
We do. A small place gets exactly the same survey as a big one.
What’s the best way to book?
To book, call 07833 053749 or use the contact form and tell us the address and what you want to find out. We will confirm the price and agree a day with you.
How does ELD work?
It uses an electrical current to find breaches in a flat roof membrane. A breach lets the current through so we can pinpoint it.
How long does electronic leak detection take?
Testing normally takes longer on a large roof than a small one, and the build-up of the roof makes a difference too.
Do you use drones?
Yes, where it is applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
When does the report arrive?
It depends on the package: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. The report is emailed to you.
What happens on the day
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. In total, it takes as long as needed for the membrane area and the build-up, which we set out in the quote. Cottages and farmhouses around Haslar frequently have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can safely be seen, and anything we can’t see is noted.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Preparing for the visit
