How electronic leak detection works in Hambrook
Water can travel under a flat roof membrane before it shows inside. So the stain inside rarely sits under the hole. Electronic leak detection tests the membrane itself, to find where it has been breached. It is testing only and leave the repair to your roofer. On a suitable roof, it takes the guesswork out of finding the hole. We then send you the results in a written report. We survey commercial flat roofs, green roofs and single-ply roofs, and common reasons people get in touch are new roofs to check before paving or planting and breaches around outlets and penetrations.
Older buildings in small places like Hambrook may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Finding out what state the roof is in gives you the facts to plan with. Listed building consent is needed for changes that affect a listed building’s special interest.
It is not only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

Landlord and commercial surveys in Hambrook
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work around your tenants.
Surveys can also be booked by buyers’ agents acting for a client. Reports are emailed, so they’re easy to pass on, photographs included.
Practical tips
Here are a few things we’d tell any owner, before and after a survey:
- Keep a note of leaks after rain
- Find the breach before more patching
- Tell us about the membrane and build-up if you know it
- Make sure trades protect the waterproofing
Questions about the results are welcome. We will explain what was found and what it means.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.
What we do, step by step
Once we have finished looking, we write up our findings in a report with photographs. On timing, most surveys take longer on a large roof than a small one, and the build-up of the roof makes a difference too. Older rural homes like those around Hambrook can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can safely be seen, and anything we cannot see is noted.
- First, you tell us about the roof build-up and where water is showing.
- The roof is assessed to see if electronic testing will work on it.
- We pick the low-voltage or high-voltage method that suits the roof.
- Testing runs across the roof to locate breaches in the membrane.
- The breaches are recorded with photographs in a report for your roofer.
How to prepare
- Jot down any questions you want answered
- For a flat or shared roof, check access with the freeholder or managing agent
- Leave a clear route to the loft

Your questions about electronic leak detection in Hambrook
Will you come out to Hambrook?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Does being near the coast affect roofs in Hambrook?
It can do. Within about 3 miles of the sea, as Hambrook is, metal fixings wear faster and gales find any loose ridge or slate.
Do you climb onto every roof?
Only where it’s safe to do so. We inspect what can be seen safely: from ground level, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where it applies. The report says if anything couldn’t be seen.
How soon will I get the report?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. Each one is emailed.
What happens after the survey?
We email you the written report with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Do you carry professional indemnity insurance?
Every survey is covered by professional indemnity and public liability insurance, and we can provide details if a managing agent needs them.
Do I have to be there for the survey?
Someone needs to let us in if we’re looking inside or in the loft. Access is agreed with you when you book.
What electronic leak detection doesn’t cover
We only report everything that’s safely in view on the day, so some things are outside what a survey can do:
- The extent of water in the insulation
- Parts of the roof covered by fixed equipment
- Repairing the breaches (that is for your roofer)

Local flat roofs in Hambrook
The coast is about 3 miles or less from Hambrook, and places near the sea get more salt in the air and more wind than inland. Salt in the air is hard on metal flashings and fixings, and wind catches any loose edge on a flat roof. The wider area around Hambrook has a long history of building, with Warblington Castle about 3.8 miles west. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material.
Take a building like Chidham Parochial Primary School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. For an older house near a landmark such as St Wilfrid's Church and Hall, flat-roofed rear additions and dormers added over the years are worth checking. Landlords with a home close to Nutbourne station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.

What we look for on each type of roof
Single-ply membranes
Many offices and units have single-ply roofs. Seams and penetrations are typical breach points.
Green and ballasted roofs
Testing before planting or ballast goes on is simpler.
Should I look at the roof myself first?
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Do not go up yourself.
