Electronic leak detection in Ossemsley
Water can travel under a flat roof membrane before it shows inside. So the stain inside rarely sits under the hole. Electronic leak detection tests the membrane itself and locates the breach. It’s testing only, and the repair is for your roofer. On a suitable roof, it takes the guesswork out of finding the hole. The results then follow in a written report with photos. We are often asked to look into damage from equipment installers and leaks at pipes, outlets or fixings, across liquid-applied waterproofing, commercial flat roofs and green roofs.
Somewhere as small as Ossemsley, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. We simply plan the journey and access beforehand. If there are outbuildings or garages with flat roofs, mention them when booking.
The report records the flat roof membrane as we found it on the day. It is useful right away, and a good reference for later, for instance when you want to check whether anything has changed.

How it works
We’ll ask a few questions first, such as when any problem began and what work has been done before. Then the inspection itself takes a length of time set by the size of the roof and how it’s built, which we’ll explain when we quote. In a small place like Ossemsley, access is usually the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- We agree the area to be tested.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Before we arrive
- Make a note of anything you’d like us to look at
- Note where any stains or damp appear
- Have any paperwork from past roof work to hand

FAQs for Ossemsley
Is my home in Ossemsley listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Does being near the coast affect roofs in Ossemsley?
Places near the sea get more wind and more salt in the air than inland, and both are hard on roofs. Salt corrodes metal fixings and flashings, and wind lifts loose slates, tiles and ridge pieces.
I live in a flat. Can you survey the roof?
Yes, once access has been agreed. Roofs over flats are often shared, so the building owner or managing agent needs to agree access. We can only inspect what we are given access to.
Is it a structural engineer’s report?
No. We are roof surveyors, not structural engineers, and it does not include calculations. We will recommend an engineer if we see signs that call for one.
Does ELD include fixing the breach?
No, our part is finding the breaches. Your roofer uses the report to target the repair.
What is electronic leak detection?
A sound membrane blocks the test current, but a hole lets it through. That lets us find breaches that are too small to see.
How many surveys have you done?
More than 5,000 surveys over 20+ years, across London and South East England.

Electronic leak detection in Ossemsley: local notes
The coast is about 3 miles or less from Ossemsley, so there’s 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. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If you look after a building like Ballard School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. Avon Tyrrell House, about 3.4 miles north-west, is one of the historic houses in the wider area around Ossemsley. If your home is older, its flat-roofed extension or dormer may be on its second or third covering. If your house is among the older ones in the streets near St John, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
Ossemsley is about 2 miles north of New Milton, in Hampshire. Anywhere in Ossemsley, we can come and survey your property, on a weekday, Saturday or Sunday. Ossemsley is one of the towns and villages in Hampshire where we work for electronic leak detection. Southampton is in our area too.

What affects the cost of electronic leak detection
We confirm the price for the job before you book. These are the things that affect it:
- How complicated the roof is, with its valleys, chimneys and parapets
- Building height and the viewpoints available
- The size of the roof
- Commercial roofs and larger buildings
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You’ll know the price for your survey before booking.
Getting in touch
Here’s what helps us most when you get in touch:
- The reason for the survey, such as buying, a leak or storm damage
- Pictures from the garden or a window, if you have them
- Anything about access we should know
- Where water is showing inside, if it is
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. For any other survey, just ring 07833 053749 or email us when you are ready.
Tips from our surveys
Small things make a difference. Some pointers:
- Keep outlets clear of debris
- Let us know about the membrane and build-up if you know it
- Check new waterproofing before handover
- Record dates and spots where water appears
After your roofer repairs the breaches, a retest can confirm them, where the roof still suits the method.
Don’t leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
How the survey changes by roof type
Liquid-applied waterproofing
Liquid waterproofing has no laps but holes and thin areas can occur. Suitability for ELD depends on the system.
Single-ply membranes
Single-ply can be punctured by tools or fixings. ELD can locate them.
Why act early in Ossemsley
Opening up a roof to hunt for a leak is disruptive. Electronic testing finds the hole first so your roofer knows where to work. Outbuildings and barns around Ossemsley are easy to forget, but a failed roof there can spoil what’s stored inside. It’s worth including them in a survey before a winter does the damage.
