Upper Common Electronic Leak Detection
Not sure what state the flat roof membrane is in? You can book electronic leak detection in Upper Common and across Hampshire, with plain-English findings.
- Leaks through a covered membrane
- Stains far from any visible defect
- Breaches around outlets and penetrations
Checking the roof from the ground
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.
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.
Electronic leak detection in Upper Common
Electronic leak detection works on many flat roof membranes, on homes, blocks and commercial buildings. It can be used to trace an existing leak or check a new membrane before handover. We quote for each roof based on its size and build-up. We can test on weekdays and at weekends when conditions allow. Just ask about your roof. We survey flat roof membranes, single-ply roofs and commercial flat roofs, and the problems we’re asked to look at most are patched roofs that still leak and damage from equipment installers.
Flat roofs on exposed homes in small places like Upper Common take more wind and rain, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, typically show it first. Rubber and GRP last longer, though trims and joints still need a look. On an exposed roof, the edges tend to go first.
The report is written in plain words, so it makes sense without any roofing background. Each point is backed by a photograph where possible, and recommendations are put with the most urgent first where relevant.

What electronic leak detection does not cover
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Sections we cannot safely access
- Build-ups without a suitable layer below
- Moisture spread under the membrane

- Liquid-applied waterproofing

What happens on the day
We look at the roof from outside and, where it’s relevant and there’s safe access, from inside the roof space too. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. All in, the survey typically takes more time on a big roof than a small one, with the construction of the roof playing a part too. Rural addresses near Upper Common can be hard to find from a postcode alone, so a few directions are welcome. The visit itself is the same as anywhere else.

Common questions in Upper Common
Do you carry out roof surveys in Upper Common?
We do. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
How do I find out if my home in Upper Common is listed?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
How quickly is the report sent?
That depends on the survey you book: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. The report is emailed to you.
What does the report include?
It works through the roof part by part, in writing and with photos, finishing with recommendations. Points are put by urgency where it matters.
How long does electronic leak detection take?
The roof’s size and build-up decide how long it takes. We will give you an idea when we quote.
Do you take photos of the roof?
Yes. Photos are taken throughout the survey, and the report uses them to show each finding.
Which method do you use?
The method is chosen to suit the roof. Low-voltage methods are normally carried out on a wet roof and high-voltage methods need the membrane dry and exposed.
What we look for on each type of roof
Inverted and paved roofs
We will tell you if your inverted or paved roof is not suitable.
Single-ply membranes
Punctures from foot traffic and equipment are common on single-ply roofs. Testing helps find them.
What we are asked to look at in Upper Common
Work on the roof can damage a membrane. Fixings, equipment and foot traffic can leave small holes.
Here are some of the things we see frequently:
- Waterproofing to test before it’s covered
- Punctures from foot traffic or tools
- A flat roof leak that can’t be traced
- Holes around roof penetrations
Take an older house close to Church of St. Martin: later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear.

What electronic leak detection looks like in Upper Common
Some Hampshire villages still have thatched roofs. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. About 3.9 miles south-east lies Hall Place, a reminder of how long the area around Upper Common has been built on. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years.
