How electronic leak detection works in Greatham
Electronic leak detection works on many flat roof membranes, on homes, blocks and commercial buildings. It can be used to trace an existing leak or to test a new membrane before it is covered. Each roof is quoted on its size and build-up. We can test on weekdays and at weekends, depending on the weather. Just ask about your roof. Common reasons to book are holes around roof penetrations and waterproofing to test before it’s covered, across roof terraces and balconies, green roofs and commercial flat roofs.
In a small place like Greatham, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. 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. On an exposed roof, the edges tend to go first.
The report records the flat roof membrane as we found it on the day. That makes it useful now and a handy reference later.

Do you need electronic leak detection in Greatham?
New membranes can have defects from installation. ELD on a new roof can show holes before they cause leaks.
A survey can pick up problems such as:
- A flat roof leak that cannot be traced
- New roofs to check before paving or planting
- Leaks at pipes, outlets or fixings
- Leaks showing away from the breach
For landlords with property near Liss station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
What to check before booking
- Their track record with similar roofs
- How long the report takes to arrive
- Which viewpoints they use to see the roof
- Will the report include photos?
Practical tips
From years of surveys, a few habits stand out as worth the effort:
- Stay off the flat roof unless needed
- Note where leaks show inside and when
- Keep outlets clear of debris
- Use boards when working on the roof
You receive a report showing where each breach was found, with photographs. Pass it to your roofer to repair the breach points.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
Why it is worth a survey now in Greatham
Some flat roof leaks come from walls or details. Testing shows whether the membrane is breached, so other causes can be checked. For older village homes like those around Greatham, the right replacement materials aren’t always easy to find quickly. Spotting a problem early leaves room to find them.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs 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.
Why us?
- An independent view of the roof
- Over 20 years’ experience
- Visits on any day of the week
- Covered by professional indemnity and public liability insurance
For landlords and managing agents
Roof problems in a rented home affect tenants as well as the building. A survey shows what needs attention, so you can plan the work around your tenants.
We also survey roofs for businesses and commercial landlords, from shops and offices to industrial units. Larger roofs take longer, so they’re priced to suit.
What electronic leak detection looks like in Greatham
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. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 conservation areas. If your home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission, so check with the council.
Anyone responsible for a site like Greatham Primary School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. If you live in an older home near Church of St John the Baptist, flat-roofed rear additions and dormers added over the years are worth checking.

FAQs for Greatham
Is Greatham within the area you cover?
Yes, Greatham is on our map. Villages and rural addresses get the same survey as a town house.
How do I find out if my home in Greatham is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
How fast do I get the report?
It depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. The report is emailed to you.
Do you look in the roof space?
Where it’s relevant to the survey and there’s safe access, yes. Please clear anything stored under the hatch.
Are you insured?
Our cover is professional indemnity plus public liability, and details are available on request.
Do you survey roofs on blocks of flats?
Yes, if the building owner or managing agent agrees access. On a shared roof we can only inspect the parts we’re allowed to reach.
Do you climb onto every roof?
Only when it is safe. Some roofs are too steep or fragile to walk on safely. We use safe viewpoints, the loft space and a drone where applicable, and the report records anything we couldn’t see.
What we do, step by step
We do not take risks to get a closer look. Everything that can be seen safely is inspected, and anything we cannot see is noted in the report. Most visits take longer on a large roof than a small one, with the construction of the roof playing a part too. For a village or hamlet like Greatham, the journey is planned in advance: 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 is safe access and from the roof where it is safe.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
How to prepare
- Make a note of anything you’d like us to look at
- If you’re buying, check with the agent that we can get in
- Point out any leaks or damp patches
