Oakhanger Electronic Leak Detection
Wondering about the flat roof membrane at a property in Oakhanger? We carry out electronic leak detection in Oakhanger and across Hampshire, with plain-English findings.
- Breaches around outlets and penetrations
- Breaches hidden under paving or planting
- Leaks through a flat roof with no obvious cause
Checking the roof from the ground
It is useful to keep a record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry.
The one thing to avoid is getting up close. Roofs are fragile and slippery. That is where a survey comes in, using safe viewpoints and a drone where applicable.
How electronic leak detection works in Oakhanger
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. 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 can repair them. The results come in a report with photos. If you’ve noticed damage from equipment installers and leaks through a flat roof with no obvious cause, we can find out what’s behind it, whatever the roof.
Somewhere as small as Oakhanger, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them when booking.
We write the report in plain English, so it makes sense without any roofing background. Each point is backed by a photo where possible, and recommendations are put in order of urgency where relevant.

The survey, step by step
On the day, we begin with a quick chat about the roof and anything that’s worrying you. We then inspect everything that can safely be seen, from ground level, from windows, in the roof space and by drone where applicable. The survey typically takes a time that depends on the membrane area and the build-up, which we’ll explain when we quote. For a village or hamlet like Oakhanger, the journey is planned beforehand: tell us about narrow lanes, gates, long drives and where we can park. The roof is looked at from ground level, from windows, from the loft where there’s safe access and from the roof where it’s safe.
- We agree the area to be tested.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Before the survey
- Leave side gates unlocked
- Let us know about parking before the day
- Dig out any old roof reports or invoices
How to book
Photos help, if you have them. Take them safely from ground level or a window; never climb up to get a better view. To send them or to book, phone 07833 053749 or use the contact form.

What else we do in Oakhanger
Roof by roof
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer but holes and thin areas can occur. Whether ELD works depends on the coating and build-up.
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing, which affects testing.
Honest limits
It’s useful to know what a survey will not do before booking:
- Fixing the holes we find
- Sections we can’t safely access
- Leaks from walls, copings or rooflights
If in doubt, phone 07833 053749 or email us and we’ll suggest the right survey. What a survey covers and does not.

Flat and commercial roofs around Oakhanger
A number of Hampshire villages keep thatched roofs on their older buildings. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. 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’s worth knowing whether it’s 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.
Take an older house close to St Mary Magdalene's Church: later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. If you look after a building such as Mill Chase Academy, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Common roof problems in Oakhanger
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:
- Leaks at pipes, outlets or fixings
- Punctures from foot traffic or tools
- Stains far from any visible defect
- Leaks through a covered membrane
Landlords with a home close to Alton station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.

Oakhanger questions
Do you cover smaller places like Oakhanger?
Yes, we do. We survey roofs across London and the South East, from towns to the smallest villages. The journey is planned ahead, so it’s useful to know about access.
Do you carry out roof surveys in Oakhanger?
Yes, Oakhanger is within the area we cover. We cover the whole of London and South East England. You can ring 07833 053749 or drop us an email with the address and a few details.
What happens next?
The report comes by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
Do you survey roofs on blocks of flats?
Yes, if whoever owns or manages the building agrees access. We check the parts we are given access to.
Do you carry out surveys on Saturdays and Sundays?
We survey seven days a week: Monday to Friday, Saturdays and Sundays. Just let us know the days that suit you.
Do you need to get into the loft?
If there’s a loft and safe access to it, yes. From inside, the underside of the roof often shows damp, staining or daylight that cannot be seen from outside.
Can you find leaks on a covered flat roof?
In some cases. The layers on top and the build-up below decide it and parts may need to be lifted. We will discuss it before we quote.
