Keyhaven Electronic Leak Detection
Not sure what state the flat roof membrane is in? We carry out electronic leak detection in Keyhaven and across Hampshire, with plain-English findings.
- Gaps at membrane joints
- Punctures from foot traffic or tools
- Water coming in under a flat roof
Tips from our surveys
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Tips:
- Consider ELD before paving or planting goes on
- Clear flat roof outlets regularly
- Record dates and spots where water appears
- Share any drawings of the roof
Questions about the results are welcome. We can talk you through the findings.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
Electronic leak detection in Keyhaven
Not every flat roof suits electronic testing. Some membranes conduct electricity themselves and some roofs do not have a suitable layer beneath the membrane. If your roof is not suitable, we will tell you before any testing. Telling us what you know about the roof’s membrane and layers helps, including drawings, specifications or the roofer’s paperwork. It saves a wasted visit. We survey liquid-applied waterproofing, roof terraces and balconies and green roofs, and people most frequently book us about damage from equipment installers and leaks through a flat roof with no obvious cause.
In a small place like Keyhaven, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. 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 normally the first part of a flat roof to go.
Findings are set out part by part, from the main slopes down to the gutters and outlets, each with a short note and a photograph. You will see the good as well as the bad.

Electronic leak detection around Keyhaven
The coast is about 1 mile or less from Keyhaven, where sea air brings more salt and stronger wind than inland. Salt in the air is hard on metal flashings and fixings, and wind catches any loose edge on a flat roof. An older home may be listed, or stand in a conservation area. Historic England’s list shows listed buildings, and the council can say whether a street is in a conservation area. In either case, a change of roofing material may need consent.
If you live in an older home near Church of All Saints, the flat roofs on later extensions tend to wear out long before the main roof. If you let a flat or house near Lymington Town station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Keyhaven is about 3 miles south of Lymington, in Hampshire. Keyhaven is one of many places we visit across Hampshire. Our area takes in places right across Hampshire, from the larger towns to small villages. We also survey roofs in Southampton.
Surveys in SO41 work the same way as everywhere else we cover. We offer electronic leak detection to properties on New Road, Keyhaven Road and Saltgrass Lane and the roads around them. If you’re just outside Keyhaven, we cover Milford on Sea (1 mile west), Lymore (1 mile north-west), Lower Pennington (1 mile north-east), Everton (2 miles north-west) and Pennington (2 miles north).

Prices for electronic leak detection in Keyhaven

What to let us know when you contact us
If you can, have these to hand when you get in touch:

- The kind of building and roof involved

Booking is simple: just ring 07833 053749 or email us and give us some details about the property and we’ll explain which survey suits. We confirm the price before anything is booked.
Common roof problems in Keyhaven
Flat roof membranes can be punctured by foot traffic, dropped tools or debris. Many are tiny, but still let water through.
A survey can pick up problems such as:
- Water coming in under a flat roof
- Failed seams and laps
- Breaches hidden under paving or planting
- Waterproofing to test before it’s covered
Anyone responsible for a site like Milford-on-Sea Church of England Primary School will know that schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.
Questions to ask before booking
- Is VAT included in the price?
- Their track record with similar roofs
- What happens after the report arrives
- When you’ll get the report
What happens if roof problems are left?
Chasing a leak again and again is frustrating. A report showing the breach points gives your roofer a clear target. Where a roof is exposed, as many are in small places like Keyhaven, driving rain gets into any weakness, and damp in older walls is slow to dry out.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.

Questions from Keyhaven
Will you come out to Keyhaven?
We do. A small place gets exactly the same survey as a big one.
Does a conservation area affect roof work in Keyhaven?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
Do you use drones?
Where it helps and it is safe, yes. Whether we can fly on the day depends on the weather and the airspace rules. We hold a CAA Flyer ID and Operator ID.
Can you test a green or ballasted roof?
It can be possible, depending on the roof. Covered roofs limit the methods we can use, so we check the build-up first.
What if it rains on the day?
It can, depending on the survey. Drone flights need calm, dry weather, and thermal imaging works best after a sunny day, with a dry roof and little wind. If the conditions aren’t right, we will talk to you about another date.
How many surveys have you done?
Over 20 years and more than 5,000 surveys.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof and can sit alongside a RICS survey.
The survey, step by step
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. In total, it takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Older roofs in small places like Keyhaven can have low, tight loft spaces, so let us know about the loft hatch and any ladder. We only go where it is safe.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Preparing for the visit
- Move anything stored under the loft hatch
- Find any records of previous roof work
- Check we can get to the back of the property
