Electronic leak detection in Horndean
Some flat roofs can’t be tested electronically. Some membranes conduct electricity themselves, and some build-ups lack the layer the test needs below the membrane. We’ll say if ELD will not work on your roof before any testing. Any details you have about the membrane and build-up help us decide, such as drawings or specifications. It avoids arranging a test that cannot give results. We’re often asked to look into holes around roof penetrations and water coming in under a flat roof, across commercial flat roofs, roof terraces and balconies and single-ply roofs.
Shops, surgeries, schools and small business units in towns like Horndean frequently have flat roofs. Out of sight, they tend to be forgotten until a leak appears. A close look at outlets, upstands and the membrane itself shows where it stands. Tell us who manages the building so access to the roof can be arranged.
Where we cannot see part of the flat roof membrane, the report says so. You will know exactly what was inspected and what wasn’t.

Common roof problems in Horndean
Water travels under flat roof membranes. The leak may show some distance from where water gets in which makes it hard to find by looking.
Look out for signs like these:
- Patched roofs that still leak
- Leaks under green or ballasted roofs
- Water coming in under a flat roof
- Gaps at membrane joints
Anyone responsible for a site like Horndean Technology College will know that a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail.

How the survey works
Safety comes first on every visit. Everything that can be seen safely is inspected, and anything we cannot see is noted in the report. The survey typically takes as long as needed for the membrane area and the build-up, which we set out in the quote. Semi-detached and terraced homes in a town like Horndean often share a roof line with the neighbours, so shared parts are looked at as far as they can be seen from your property. It is useful to know about previous repairs, leaks or recent work, so time on site goes where it’s needed.
- We agree the area to be tested.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Getting ready for the survey
- Mention any parking restrictions on your street
- If it is not your property yet, arrange access through the agent
- Keep pets out of the way during the survey

Tips from our surveys
A few practical points come up again and again on our surveys. They apply to most roofs:
- Consider ELD before paving or planting goes on
- Share any drawings of the roof
- Find the breach before more patching
- Use boards when working on the roof
If anything in the report isn’t clear, ask us. We’ll explain what was found and what it means.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.
Prices for electronic leak detection in Horndean

Helping us price your survey
Here’s what helps us most when you get in touch:
- When you need the report by
- Any marks or damp showing indoors
- Any photos you have, taken from the ground or a window
- The style of property, from a terrace to a block
Photos help, if you have them. Take them safely from ground level or a window; never climb up to get a better view. To send them or to book, ring 07833 053749 or send us an email.
Leave it or get it looked at?
Patching where you think the leak is frequently misses it. ELD shows the actual breach points. Around Horndean, water from a roof defect frequently goes unseen for a while, such as the loft insulation, the top of a wall or the roof timbers. By the time it shows inside, the job has grown.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.

Horndean: your questions answered
Is my home in Horndean listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do roofs near the sea, like those around Horndean, take more of a battering?
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.
What happens after the survey?
We email you the written report with photos and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
How long does electronic leak detection take?
Testing usually takes a time that depends on the membrane area and the build-up, and we’ll give you a guide when quoting.
Will I get photos?
Yes. The report includes photos of what we found, so you can see exactly what each finding refers to.
Which days do you carry out surveys?
We carry out surveys seven days a week. To find a day that suits you, ring 07833 053749 or email us.
What does the report include?
You get our findings in writing, part by part, with photos, and ends with what we recommend. Points are put with the most urgent first where relevant.
Flat roofs in Horndean
Horndean lies within about 5 miles of the sea, and places near the sea get more salt in the air and more 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. Historic houses such as Warblington Castle, about 4.8 miles south-east, show how far back building in the area around Horndean goes. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area.
If you live in an older home near Saint Wilfrid's, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. If you own a rental within reach of Rowlands Castle station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
