Electronic leak detection in Steep Marsh, Hampshire
Electronic leak detection to pinpoint holes in flat roof membranes for Steep Marsh and the rest of Hampshire. We survey on any day of the week.
- A flat roof leak that can’t be traced
- Stains far from any visible defect
- Repairs that haven’t stopped the leak
Why act early in Steep Marsh
Some flat roof leaks come from walls or details. ELD helps rule the membrane in or out, so other causes can be checked. Older cottages and farmhouses around Steep Marsh can have roof timbers that have been there a very long time, and water through a failed covering can rot timber if it is left.
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You will know the price for your roof before booking.

Electronic leak detection in Steep Marsh
A leak in a flat roof frequently shows up a long way from where the water gets in. So the stain inside rarely sits under the hole. Electronic leak detection tests the membrane itself and locates the breach. We test and report and leave the repair to your roofer. On suitable roofs, it replaces guesswork with a located breach. The results then follow in a written report with photos. We survey green roofs, flat roof membranes and commercial flat roofs, and the problems we’re asked to look at most are waterproofing to test before it’s covered and breaches around outlets and penetrations.
In a small place like Steep Marsh, a flat roof can stand in the open, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, usually show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are usually the first part of a flat roof to go.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

What happens on the day
Photographs are taken throughout the visit, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available. A typical visit takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. In a hamlet or village like Steep Marsh, a postcode doesn’t always lead to the right gate, so a few directions are welcome. After that, the survey runs as it would anywhere.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We check that the membrane and build-up suit electronic leak detection.
- We pick the low-voltage or high-voltage method that suits the roof.
- We test the membrane and find where current is passing through it.
- We send a report with photos of each breach so your roofer can repair it.
Before the survey
- Buyers: confirm access with the estate agent or seller
- Agree roof access with the managing agent if it’s shared
- Let us know about parking near the property

Electronic leak detection in Steep Marsh: local notes
A number of Hampshire villages keep thatched roofs on their older buildings. 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 a good many flat ones, over rear extensions, dormers, garages and shops. If your home is older, it is worth knowing whether it is listed or in a conservation area before planning roof work. Listed building consent covers changes to a listed building’s special interest, and an Article 4 direction can bring extra controls in a conservation area.
If you look after a building such as Steep Church of England Voluntary Controlled Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. Landlords with a home close to Petersfield station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round. The streets around a church such as Church of All Saints are frequently among the oldest in a place, and if yours is one of the older homes nearby, the flat roofs on later extensions tend to wear out long before the main roof.

Steep Marsh: your questions answered
How do I find out if my home in Steep Marsh is listed?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
Will you come out to Steep Marsh?
Yes, Steep Marsh is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Do you carry out surveys on Saturdays and Sundays?
We carry out surveys on weekdays and at weekends. To arrange a date, call 07833 053749 or drop us an email.
Does the report include photos?
Yes. Photographs are taken throughout the survey, and the report uses them to show each finding alongside our recommendations.
Does this replace a RICS home survey?
No. It’s a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof and can sit alongside a RICS survey.
Will you walk on the roof?
Only where it is safe to do so. We check everything that can safely be seen: from ground level, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where applicable. The report says if anything couldn’t be seen.
Can every flat roof be tested?
Not every roof is suitable. Certain membranes are conductive and some roofs lack the layer the test needs. If your roof will not work, we’ll say so before testing.
What we cannot see
Every survey has limits, and we’d rather be clear about that before booking. Bear these in mind:
- How wet the insulation is
- Leaks from walls, copings or rooflights
- Repairing the breaches (that’s for your roofer)

Practical tips
Here are a few things we’d tell any owner:
- Tell us about the membrane and build-up if you know it
- Stay off the flat roof unless needed
- Get leaks traced quickly
- Clear flat roof outlets regularly
Wet insulation may need attention after a leak. That is something to discuss with your roofer and other checks can help judge it.
Keep outlets and gutters on flat roofs clear. Standing water puts more pressure on any weak point.
