Electronic leak detection in Rowlands Castle
Electronic testing locates holes in the waterproofing but not every way water gets in. Water coming through walls, copings, rooflights or plumbing will not show on the test. If the evidence points elsewhere, we will say so. It won’t show water getting in through brickwork or around frames. Our report keeps that distinction clear. We will point you to the likely next step. If you’re worried about leaks through a flat roof with no obvious cause and leaks through a covered membrane, a survey will tell you what’s going on, whatever the roof.
In a smaller place like Rowlands Castle, some flat roofs sit in the open, so wind catches loose edges and trims. Felt and bitumen also age in strong sun. Splits, blisters and lifting edges are what to look out for. A flat roof that still holds water days after rain is also worth a closer look.
Nothing in the report is left vague: where something needs attention, it says so plainly, and where it can wait, that is said too.

Tips that help
These tips come from what we see on roofs every week, before and after a survey:
- Check new waterproofing before handover
- Stay off the flat roof unless needed
- Avoid repeated repairs without finding the cause
- Share any drawings of the roof
Keep the report with the roof’s records. It is a dated record of the membrane’s condition.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.

Different roofs, different checks
Single-ply membranes
Many offices and units have single-ply roofs. Laps and fixings are where holes frequently appear.
Bituminous membranes
Older felt roofs frequently have seams and patches that can leak. Testing depends on the roof.
What a survey costs
We confirm the price for the job before you book. This is what makes a difference:
- How tall the building is and how easy the roof is to see
- The number of roofs, including extensions and garages
- The shape of the roof and its details
- If the survey needs thermal imaging or a drone
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.
What to tell us when you contact us
Before you get in touch, it is useful to have:
- Where water is showing inside, if it is
- Where the property is, with the postcode
- Any deadline, such as an exchange date
- Whether there’s a loft hatch, a shared roof or tricky access
If you’re buying, it helps to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply phone 07833 053749 or drop us an email whenever suits you.

Common questions in Rowlands Castle
How do I find out if my home in Rowlands Castle is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Do roofs near the sea, like those around Rowlands Castle, take more of a battering?
It can do. Within about 3 miles of the sea, as Rowlands Castle is, metal fixings wear faster and gales find any loose ridge or slate.
How long will testing take?
It depends on the size of the roof and its build-up. We will give you an idea when we quote.
What does electronic leak detection do?
It uses an electrical current to find breaches in a flat roof membrane. The current only gets through where the membrane is breached so we can pinpoint it.
Will you go up on the roof?
Only where it’s safe to do so. We inspect everything that’s safely in view: from ground level, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where applicable. Anything we cannot see is noted in the report.
What happens after the survey?
The report comes by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
Will you repair the leak?
No, our part is finding the breaches. The report gives your roofer the locations.
Electronic leak detection around Rowlands Castle
The coast is about 3 miles or less from Rowlands Castle, where sea air brings more salt and stronger wind than inland. Coastal wind works at the edges of flat roofs, and salt air wears metal trims and fixings. The wider area around Rowlands Castle has a long history of building, with Warblington Castle about 3 miles south. If your house is among the older ones, expect a mix of original materials and later repairs on the roof.
Anyone responsible for a site like Havant Academy will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. For landlords with property near Rowlands Castle station, the flat roof over a let home is worth a look before it becomes a tenant complaint. If you live in an older home near The Church on the Green, the joins between later flat roofs and the old walls are where problems typically start.

The survey, step by step
We’ll ask a few questions first, about the roof’s history, any leaks and past repairs. Then the inspection itself takes longer on a large roof than a small one, with the construction of the roof playing a part too. Some parts of a survey depend on the weather, so a visit to Rowlands Castle is booked with the forecast in mind: the parts that need calm, dry weather are planned around it.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Before the survey
- Dig out any old roof reports or invoices
- Point out any leaks or damp patches
- Move anything stored under the loft hatch
How to book
If you have photos of the roof, send them over. Pictures from ground level or a window are fine, and please don’t climb up for a closer look. To get started, call 07833 053749 or drop us an email.
