Electronic leak detection around St Leonards
What can be done to an older roof may depend on listing or a conservation area. Your council and Historic England’s list will tell you where you stand, ideally before any re-roofing is planned. Some Hampshire villages still have thatched roofs. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops.
Anyone responsible for a site like St Ives Primary & Nursery School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Electronic leak detection in St Leonards
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small electrical current that passes through the membrane only where there is a breach. It can find holes too small to spot by eye, so your roofer can repair them. The results come in a report with photos. We survey single-ply roofs, commercial flat roofs and roof terraces and balconies, and people most frequently book us about repairs that haven’t stopped the leak and new roofs to check before paving or planting.
Around St Leonards, many homes have a garden room, garage or outbuilding with a flat roof. They’re rarely looked at until something gets wet. It’s worth mentioning them when you book, so the visit can include them, along with the main flat roof. Felt, rubber and GRP coverings on garages and outbuildings age in just the same way as the main roof’s.
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.

Before and after the survey
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Consider ELD before paving or planting goes on
- Find the breach before more patching
- Keep foot traffic on flat roofs to a minimum
- Ask contractors to protect the membrane
The report records each breach location with photos. Your roofer uses it to carry out repairs.
Keep outlets and gutters on flat roofs clear. Standing water puts more pressure on any weak point.
What happens on the day
We will ask a few questions first, such as when any problem began and what work has been done before. Then the inspection itself takes as long as needed for the size of the roof and how it’s built, which we set out in the quote. With a bit of garden around a house, as there often is around St Leonards, the roof can be viewed from several angles. Mention any side of the property we can’t get to. The loft, where there is safe access, completes the picture.
- You tell us about the roof and where water is showing.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
Before we arrive
- Leave side gates unlocked
- Point out any leaks or damp patches
- If it isn’t your property yet, arrange access through the agent

Signs you need electronic leak detection in St Leonards
A breach can be left during installation. ELD on a new roof can show holes before they cause leaks.
Common reasons to book include:
- Leaks under green or ballasted roofs
- Punctures from foot traffic or tools
- Holes around roof penetrations
- Damp inside with no sign on the roof
Take an older house close to All Saints: flat-roofed rear additions and dormers added over the years are worth checking.
What to check before booking
- What exactly goes into their report
- Their drone registration, if they fly one
- What follow-up you get after the report
- How long they’ve been surveying roofs
What affects the price in St Leonards
Not every roof costs the same to survey, for these reasons:
- Extensions, dormers and garages with roofs of their own
- If the survey needs thermal imaging or a drone
- Whether it is a home or a commercial building
- Building height and the viewpoints available
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You will know the figure before booking.

How long does electronic leak detection take?
Testing typically takes more time on a big roof than a small one, and the build-up of the roof makes a difference too.
Can you test a green or ballasted roof?
On some roofs, yes. Covered roofs limit the methods we can use, so we check the build-up first.
Can you tell me if my roof has asbestos?
No. We do not carry out asbestos surveys or testing. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them and suggest a specialist asbestos surveyor checks them before any work.
