How electronic leak detection works in Welborne
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small electrical current which can only get through the membrane at a breach. It can find holes too small to spot by eye so your roofer knows exactly where to repair. The results come in a report with photos. Common reasons to book are new roofs to check before paving or planting and breaches around outlets and penetrations, across commercial flat roofs, liquid-applied waterproofing and green roofs.
Some older homes in villages like Welborne are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you are planning work, check with the council first. Knowing the roof’s condition is the starting point. Listed building consent is needed for changes that affect a listed building’s special interest.
After the visit, you get a written report with photos, emailed to you. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

What this survey can’t tell you
Without opening up the roof, some things stay hidden, so a survey has limits:
- Sections we can’t safely access
- The extent of water in the insulation
- Repairing the breaches (that is for your roofer)

Flat roofs in Welborne
Welborne lies within about 3 miles of the sea, and being near the sea means more wind and salt than a roof inland would face. Coastal wind works at the edges of flat roofs, and salt air wears metal trims and fixings. 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.
For landlords with property near Fareham station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. If you look after a building such as The Henry Cort Community College, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. The streets around a church like Church of St Francis are often among the oldest in a place, and if yours is one of the older homes nearby, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
Welborne is about 2 miles north of Fareham, in Hampshire. Wherever you are in Welborne, we can come and survey your property, on a weekday, Saturday or Sunday. We cover towns and villages across Hampshire. There’s also a page for Portsmouth.

Why get it checked now?
Patching where you think the leak is often misses it. ELD shows the actual breach points. Older cottages and farmhouses around Welborne can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it’s left.

Tips from our surveys
A survey works best with a little help from you, before and after. Tips:
- Use boards when working on the roof
- Check new waterproofing before handover
- Keep foot traffic on flat roofs to a minimum
- Have roof specifications to hand
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
Clear flat roof outlets regularly. Water that sits on the roof finds breaches faster.
What happens on the day
We don’t take risks to get a closer look. We inspect everything that’s safely in view, and anything we cannot see is noted in the report. The survey typically takes more time on a big roof than a small one, with the construction of the roof playing a part too. Cottages and farmhouses around Welborne frequently have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can safely be seen.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
Preparing for the visit
- Have keys ready for side gates, garages or roof access doors
- Point out any leaks or damp patches
- Tell us where we can park nearby

Related advice
Your questions about electronic leak detection in Welborne
Does being near the coast affect roofs in Welborne?
Places near the sea get more wind and more salt in the air than inland, and both are hard on roofs. Salt corrodes metal fixings and flashings, and wind lifts loose slates, tiles and ridge pieces.
Will you come out to Welborne?
Yes, Welborne is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
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.
Does this replace a RICS home survey?
No. We check the roof, not the whole building, so it’s not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
How long does electronic leak detection take?
It typically takes more time on a big roof than a small one, and the build-up of the roof makes a difference too.
Does the report include photographs?
Yes. Photos are part of every report.
Is it a structural engineer’s report?
No. We note visible signs such as sagging or deflection, but we do not carry out calculations or give an engineer’s opinion. If we think you need an engineer, the report says so.
Should I look at the roof myself first?
What you can’t do safely is get up close. Roofs are fragile and slippery, and a fall can be serious. That part is for a survey, using safe viewpoints and a drone where it applies.
Look up at the roof after a storm, from ground level: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
Rented homes, blocks and businesses
Landlords, agents and building managers in Welborne and across Hampshire can book any of our surveys. For a price for a let property or a block, phone 07833 053749 or email us.
