Electronic leak detection in Langstone, Hampshire
A careful look at the flat roof membrane at your property in Langstone, with photos and a written report.

How electronic leak detection works in Langstone
You get a report showing the location of each breach, with photographs. It tells your roofer exactly where to repair rather than guessing. Repair costs aren’t part of the report, so your roofer prices the work. Testing again after repairs can confirm the breaches have been dealt with if the build-up allows. Results come in a written report with photos. We are frequently asked to look into breaches hidden under paving or planting and gaps at membrane joints, across single-ply roofs, green roofs and flat roof membranes.
In a village or hamlet like Langstone, flat roofs are usually on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access ahead of time. If there are outbuildings or garages with flat roofs, mention them when you book.
After the visit, you get a photo-illustrated written report, emailed to you. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

How we price electronic leak detection
To price your survey, we check:
- Roof area
- How tall the building is and how easy the roof is to see
- The shape of the roof and its details
- The type of building, from a house to a block or an office
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You will know the exact price before booking.
What to tell us when you contact us
A little information up front helps. Please include:
- Any deadline, such as an exchange date
- Anything about access we should know
- Why you want a survey: buying, a leak, a storm or new work
- Photos of the roof, taken safely from the ground or a window
Most bookings start with a short call: ring 07833 053749 or send us an email and we will ask a few questions about the roof. You’ll have a price before anything is arranged.
Electronic leak detection in Langstone: local notes
Langstone lies within about 1 mile of the sea, and being near the sea means more wind and salt than a roof inland would face. On a flat roof near the sea, edge trims and upstands take the brunt of the wind, and metal parts corrode faster. The wider area around Langstone has a long history of building, with Warblington Castle about 0.8 miles north-east. Older homes in the wider area frequently have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first.
If you own a rental within reach of Havant station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. If your home is one of the older ones in the streets near Saint Nicholas' Chapel, the flat roofs on later extensions tend to wear out long before the main roof.
Langstone is about 2 miles south of Havant, in Hampshire. We carry out electronic leak detection for homeowners, landlords and businesses in Langstone and the surrounding area. Langstone is one of the places in Hampshire we cover for electronic leak detection.
Here we cover the PO9 and PO11 postcode area for electronic leak detection. That includes homes and businesses on Mill Lane, Langstone Road and Langstone High Street and the roads around them. Being close to the A3023, Langstone is easy for us to reach. We also cover the places around Langstone: Warblington (1 mile east), Northney (1 mile south-east), Denvilles (1 mile north-east), Stoke (1 mile south) and North Hayling (1 mile south-east).

Well-known places in the area include Warblington Castle (0.8 miles north-east) and Havant Museum (0.8 miles north). Not far away are Southmoor Nature Reserve.
What we do, step by step
The aim of the visit is simple: to see as much of the flat roof membrane as can be seen safely and record it clearly. Notes and photos go into the written report. The visit normally takes longer on a large roof than a small one, with the construction of the roof playing a part too. In a small place like Langstone, access is usually the main thing to plan. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
- You tell us 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.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Preparing for the visit
- If the roof is shared, arrange access with whoever manages the building
- Make sure we can get to the back of the property
- Keep pets inside or away from the areas we’re looking at

What else we do in Langstone
Can I check my roof myself?
A DIY look is useful, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.
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.
Roof by roof
Single-ply membranes
Punctures from foot traffic and equipment are common on single-ply roofs. Testing helps find them.
Green and ballasted roofs
Some layers may need lifting for testing. We explain what’s needed when we quote.
Questions from Langstone
Will you come out to Langstone?
Yes, Langstone is covered. We survey roofs across London and South East England, and smaller places are part of that. The journey is planned ahead, so it’s useful to know about access.
Does being near the coast affect roofs in Langstone?
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.
Is this a RICS survey?
No. This is a survey of the roof only, so it’s not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
How do you choose the testing method?
The method is chosen to suit the roof. Low-voltage methods are usually carried out on a wet roof, while high-voltage testing needs a dry, exposed membrane.
Will you repair the leak?
No, our part is finding the breaches. The report gives your roofer the locations.
How is ELD priced?
We quote electronic leak detection for each roof, as the method and time depend on the roof. The price depends on the roof’s size and build-up. For a quote, call 07833 053749 or email us.
Will you fly a drone over my roof?
Where it helps and it’s safe, yes. Whether we can fly on the day depends on the weather and the airspace rules, and we check for restrictions near airports before flying. We hold a CAA Flyer ID and Operator ID.
Do you need electronic leak detection in Langstone?
A breach can be left during installation. ELD on a new roof can show holes before they cause leaks.
Problems we come across often include:
- Leaks at pipes, outlets or fixings
- Leaks that return after repairs
- Leaks showing away from the breach
- Leaks through a flat roof with no obvious cause
Take a building like Bosmere Junior School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Questions to ask before booking
- Which viewpoints they use to see the roof
- Their insurance cover
- How much experience they have with roofs like yours
- Which limits apply to the survey
