- Leaks through a covered membrane
Signs you need electronic leak detection in Picket Twenty
Roofs covered with paving, ballast or planting hide the membrane. Electronic methods can help on some of these roofs though it depends on the layers.
Signs worth acting on include:
- Waterproofing to test before it’s covered
- Repairs that haven’t stopped the leak
- Breaches around outlets and penetrations
- A flat roof leak that can’t be traced
If you look after a building like Pilgrims' Cross CofE Aided Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
Before booking any roof surveyor
- What they will not be able to tell you
- What happens after the report arrives
- What the report includes, and whether it has photos
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
Electronic leak detection for homes and businesses in Picket Twenty
ELD finds breaches in the membrane, not every cause of water getting in. Water coming through walls, copings, rooflights or plumbing will not show on the test. We’ll tell you if we think the leak is coming from somewhere else. It won’t show water getting in through brickwork or around frames. Our report keeps that distinction clear. You will also know what to check next. We survey single-ply roofs, green roofs and flat roof membranes, and the problems we are asked to look at most are new roofs to check before paving or planting and leaking laps in the waterproofing.
Flat roofs on exposed homes in small places like Picket Twenty take more wind and rain, so edges, upstands and laps take a beating. Older felt roofs, often around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are typically the first part of a flat roof to go.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. That way, it is clear what was covered and what wasn’t, and what we’d suggest next.

- Build-ups without a suitable layer below
- Repairing the breaches (that is for your roofer)

Your questions about electronic leak detection in Picket Twenty
Do you cover commercial flat roofs around Picket Twenty?
Yes, we cover commercial roofs as well as homes. Roof access is agreed with the building manager or owner beforehand.
Will you come out to Picket Twenty?
We do. A small place gets exactly the same survey as a big one.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and sampling aren’t something we do. Where a material might contain it, such as old cement sheets on a building from before 2000, the report flags it, with a recommendation to have a specialist asbestos surveyor check before it is disturbed.
Do I have to be there for the survey?
Not necessarily. If we only need the outside, we can agree that in advance, but anything inside needs someone there to give access.
What is electronic leak detection?
A sound membrane blocks the test current, so wherever there’s a hole, it passes through. That is how we locate breaches you cannot see.
Will you fly a drone over my roof?
Yes, where it is applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
Does this replace a RICS home survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
Electronic leak detection in Picket Twenty: local notes
Before planning roof work on an older home, find out whether it’s listed or in a conservation area. 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. There are several hotels within about a mile and a half of Picket Twenty, and hotels, like offices and blocks of flats, often have flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
If you own one of the older houses in the streets near United Reformed Church, the joins between later flat roofs and the old walls are where problems typically start. Landlords with a home close to Andover station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.

DIY checks: what’s safe
A DIY look is useful, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground, and those are details a survey looks at closely.
Keep a simple record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry and it will help the survey.
Before and after the survey
There’s plenty you can do without going near the roof. Here’s what helps most:
- Check trades protect the waterproofing
- Clear flat roof outlets regularly
- Keep a note of leaks after rain
- Find the breach before more patching
The report records each breach location with photos. Pass it to your roofer to repair the breach points.
Clear flat roof outlets regularly. Water that sits on the roof finds breaches faster.

What happens on the day
There is not much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we will take it from there. A typical survey takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Around Picket Twenty, older homes can have small or awkward roof spaces, so let us know about the loft hatch and any ladder. We only go where it is safe.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We confirm whether the roof is suitable for electronic testing.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
Before we arrive
- Have any paperwork from past roof work to hand
- Agree roof access with the managing agent if it is shared
- Make sure pets are kept safely away
Arrange a survey
