St Mary Bourne Electronic Leak Detection
Need electronic leak detection in St Mary Bourne? We can help, with findings in writing and pictures to back them up. Book a weekday or weekend visit.
- Failed seams and laps

- New roofs to check before paving or planting
Checking the roof from the ground
Your own check is a good start, but it isn’t a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight.
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
About our electronic leak detection in St Mary Bourne
Electronic testing locates holes in the waterproofing, not every cause of water getting in. Water coming through walls, copings, rooflights or plumbing won’t show on the test. We will tell you if we think the leak is coming from somewhere else. It will not show water getting in through brickwork or around frames. Our report keeps that distinction clear. You will also know what to check next. If you are worried about leaks through a flat roof with no obvious cause and holes around roof penetrations, a survey will tell you what’s going on, on roof terraces and balconies, green roofs and single-ply roofs alike.
In a small place like St Mary Bourne, 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. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are usually the first part of a flat roof to go.
Findings are set out part by part, from the coverings down to the gutters, each with a short note and a photo. You’ll see the good as well as the bad.

Common roof problems in St Mary Bourne
New membranes can have defects from installation. Testing before the roof is covered or handed over helps find them.
We are often asked to look at:
- Patched roofs that still leak
- Damp inside with no sign on the roof
- Gaps at membrane joints
- Damage from equipment installers
For site and facilities teams at buildings like St Mary Bourne Primary School, a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.

Flat roofs in St Mary Bourne
A number of Hampshire villages keep thatched roofs on their older buildings. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. If your home is older, it is worth knowing whether it’s listed or in a conservation area before planning roof work. Changes that affect a listed building’s special interest need listed building consent, and councils can also use Article 4 directions to control changes in conservation areas.
If you live in an older home near Church of St Peter, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. Landlords with a home close to Whitchurch (Hampshire) station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.

St Mary Bourne questions
Do you cover St Mary Bourne?
Yes. We cover the whole of London and South East England, and St Mary Bourne is part of that. Just phone 07833 053749 or drop us an email and let us know about the property.
Is my home in St Mary Bourne listed or in a conservation area?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
How does ELD work?
ELD passes a small electrical current across the roof to locate holes in the membrane. The current only gets through where the membrane is breached, which shows us where the hole is.
Can you survey at the weekend?
Visits run seven days a week in the daytime. Just say which days work for you.
Can you survey a shared roof?
Yes, once whoever controls the roof agrees access. We check the parts we are given access to.
Can you inspect my roof with a drone?
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’re a CAA-registered drone operator.
What do I do with the report?
You receive the written report by email, with photographs and recommendations. It is yours to share with a seller, insurer, roofer or managing agent, whichever applies.

What we look for on each type of roof
EPDM rubber roofs
Certain rubber membranes are conductive which can limit electronic testing. We will tell you if yours isn’t suitable.
Green and ballasted roofs
Some layers may need lifting for testing. We discuss this before quoting.
Tips from our surveys
A survey works best with a little help from you, before and after. Some tips:
- Note where leaks show inside and when
- Use boards when working on the roof
- Keep foot traffic on flat roofs to a minimum
- Avoid repeated repairs without finding the cause
You receive a report showing where each breach was found, with photographs. Your roofer uses it to carry out repairs.
Consider testing a new membrane before it’s covered. Finding breaches is simpler at that stage.
What we do, step by step
Before we start, let us know why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. Most visits take more time on a big roof than a small one, with the construction of the roof playing a part too. Around St Mary Bourne, older homes can have small or awkward roof spaces, so it helps to know whether there is a loft hatch and how easy it is to reach. We only go where it’s safe.
- We start by finding out what the roof is made of and where it leaks.
- We confirm whether the roof is suitable for electronic testing.
- The method depends on the membrane and what sits above and below it.
- Testing runs across the roof to locate breaches in the membrane.
- You get a report showing where each breach is, for your roofer to repair.
Before the survey
- If you’re buying, check with the agent that we can get in
- Point out any leaks or damp patches
- Check the loft hatch can be reached
