Electronic leak detection in Cowplain, Hampshire

About our electronic leak detection in Cowplain
ELD can be carried out in more than one way. Low-voltage methods usually need a wet roof surface and high-voltage methods need the membrane dry and exposed. The right method depends on the membrane and the build-up of the roof, and we’ll explain our choice. We will say if your roof doesn’t suit either method before any testing starts. Common reasons to book are leaks at pipes, outlets or fixings and damp inside with no sign on the roof, across liquid-applied waterproofing, green roofs and roof terraces and balconies.
Around a smaller place like Cowplain, flat roofs typically cover extensions, garages and dormers. Even a small flat roof can let a good many water into the room below. Knowing the covering and how it was laid tells you what to expect from it. From an upstairs window, look for standing water, splits and edges coming away.
After the visit, you get a written report with photos, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

Signs you need electronic leak detection in Cowplain
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.
A survey makes sense if you’ve noticed:
- Breaches around outlets and penetrations
- Stains far from any visible defect
- Waterproofing to test before it’s covered
- Patched roofs that still leak
For an older house near a landmark such as The Hart Plain Church, the flat roofs on later extensions tend to wear out long before the main roof.
What to check before booking
- What insurance they carry
- Is there a chance to talk the report through?
- What exactly goes into their report
- How they’ll see the roof: from the ground, the loft, the roof or by drone

What else we do in Cowplain
Cowplain: your questions answered
Will you come out to Cowplain?
Yes, Cowplain is covered. We cover the whole of London and South East England, from towns to the smallest villages. Longer journeys are simply planned in advance.
How do I find out if my home in Cowplain is listed?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Does electronic leak detection work on all membranes?
ELD does not suit every roof. Some membranes conduct electricity and some roofs lack the layer the test needs. If your roof will not work, we’ll say so at the start.
What’s the price of ELD?
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, phone 07833 053749 or use the contact form.
When does the report arrive?
That depends on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. The report is emailed to you.
Do I need to be at home?
Not always. If we only need the outside, we can agree that ahead of time, but the loft and any rooms with damp need someone to let us in.
Do you survey roofs on blocks of flats?
Yes. Shared roofs just need a little more planning, with the freeholder or managing agent. Mention it when you contact us and we will plan the survey around it.
Different roofs, different checks
EPDM rubber roofs
Certain rubber membranes are conductive which can limit electronic testing. We will say if the test will not work.
Single-ply membranes
Punctures from foot traffic and equipment are common on single-ply roofs. Testing helps find them.
The survey, step by step
We do not take risks to get a closer look. We inspect everything that’s safely in view, and if part of the roof can’t be seen, the report says so. Most visits take as long as needed for the size of the roof and how it’s built, which we’ll explain when we quote. A visit to Cowplain is planned like any other: the time, the access and where to park are agreed beforehand. Visits can be on weekdays, Saturdays or Sundays. Tell us about any garages, outbuildings or extensions you want included.
- We start by finding out what the roof is made of and where it leaks.
- The roof is assessed to see if electronic testing will work on it.
- The method depends on the membrane and what sits above and below it.
- The roof is tested and any breaches are located.
- You get a report showing where each breach is, for your roofer to repair.
Preparing for the visit
- Agree roof access with the managing agent if it is shared
- Move anything stored under the loft hatch
- Keep pets out of the way during the survey
Book a survey
Getting a price is simple: just call 07833 053749 or send us an email, let us know about the property and we’ll explain which survey suits. The price is agreed up front.
Related advice
Electronic leak detection in Cowplain: local notes
The coast is about 4 miles or less from Cowplain, so there is 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. About 4.5 miles south-east lies Warblington Castle, a reminder of how long the area around Cowplain has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
For site and facilities teams at buildings like Woodcroft Primary, a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail. For landlords with property near Rowlands Castle station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Cowplain is about 1 mile south-west of Horndean, in Hampshire. Surveys in Cowplain work the same way as everywhere we cover: a careful look at whatever is safely visible, photos and a clear written report. Cowplain is one of the places in Hampshire where we work for electronic leak detection. For surveys nearby, see our Portsmouth page.
Surveys in PO8 and PO7 are booked the same way as anywhere else. That includes homes and businesses on Milton Road, King's Road and London Road and the roads around them.

Tips from our surveys
You don’t need to be a roofer to help. Here’s what helps most:
- Keep outlets clear of debris
- Don’t leave water getting in
- Keep a note of leaks after rain
- Tell us about the membrane and build-up if you know it
You receive a report showing where each breach was found, with photos. Pass it to your roofer to repair the breach points.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.
What affects the cost of electronic leak detection
When we price a survey, we consider:
- The type of building, from a house to a block or an office
- The height of the building and how the roof can safely be seen
- The roof’s overall size
- How many separate roofs there are, such as extensions, dormers and garages
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.
Booking your survey
If you can, have these to hand when you get in touch:
- Your timetable, such as an exchange date
- Pictures from the garden or a window, if you have them
- What made you get in touch
- The property’s address and postcode
We confirm the price for your survey before booking, so you know the cost up front. Electronic leak detection is quoted for your roof, because the method depends on the roof. To book, call 07833 053749 or use the contact form.
DIY checks: what’s safe
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That part is for a survey, using safe viewpoints and a drone where it applies.
