Electronic leak detection in New Zealand, Buckinghamshire
A careful look at the flat roof membrane at your property in New Zealand, and put it all in a photo-illustrated written report.
- New membranes needing a check before handover
- Leaks through a flat roof with no obvious cause
- Patched roofs that still leak
How it works
The visit has one job: to see as much of the flat roof membrane as can safely be seen and record it clearly. Everything we note and photograph goes into the written report. The visit typically takes 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 New Zealand 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.
- First, we confirm which roof areas are included.
- 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 we arrive
- Keep pets in another room
- Have any questions written down, so nothing gets missed
- Mention any parking restrictions on your street
Booking a survey
Booking is simple: just phone 07833 053749 or use the contact form and give us a few details about the property and we’ll explain which survey suits. We confirm the price before anything is booked.

How electronic leak detection works in New Zealand
We carry out electronic leak detection on flat roofs in New Zealand and across London and the South East. Testing usually takes longer on a large roof than a small one, with the construction of the roof playing a part too. Electronic leak detection is quoted for your roof, because the method depends on the roof. You get a photo-illustrated written report. If you’ve noticed patched roofs that still leak and leaks under green or ballasted roofs, we can find out what’s behind it, whatever the roof.
Flat roofs on exposed homes in small places like New Zealand take more wind and rain, which is hard on edges, upstands and joins in the covering. Older felt roofs, often around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. On an exposed roof, the edges tend to go first.
We write the report in plain English, so it makes sense without any roofing background. Each point is backed by a photo where possible.

Rented homes, blocks and businesses
If you own several properties, surveys can be booked for more than one address. To arrange surveys for several addresses, call 07833 053749 or drop us an email.
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work with less disruption.
Questions from New Zealand
Is New Zealand within the area you cover?
Yes, New Zealand is covered. Our area covers London and South East England, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Does a conservation area affect roof work in New Zealand?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Will I get photos?
Yes. Photographs are part of every report.
Is this an asbestos survey?
No. We do not carry out asbestos surveys or testing. If we see materials that could contain asbestos, like cement roof sheets or soffits on buildings from before 2000, we flag them.
What does the report include?
It explains what we saw, what it means and what we’d suggest, with photographs throughout. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
Do you climb onto every roof?
Only when it’s safe. Safe viewpoints, the roof space and a drone where it applies cover most of what’s needed.
Is it the same as a RICS Level 2 or Level 3 survey?
No. This is a survey of the roof only, so it’s not a RICS Level 2 or Level 3 survey. Many buyers have both.
Tips from our surveys
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Check trades protect the waterproofing
- Consider ELD before paving or planting goes on
- Do not let outlets block
- Let us know about the membrane and build-up if you know it
Questions about the results are welcome. We will explain what was found and what it means.
Keep outlets and gutters on flat roofs clear. Standing water puts more pressure on any weak point.
Local flat roofs in New Zealand
Thatch survives on some older buildings in Buckinghamshire’s villages. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops. Before planning roof work on an older home, find out whether it’s listed or in a conservation area. 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.
For landlords with property near Aylesbury station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. If you run a business near Friars Square, a flat roof over a business is out of sight and out of mind until it leaks.
New Zealand is about 1 mile west of Elmhurst, in Buckinghamshire. Roofs in New Zealand get the same thorough look as anywhere else in Buckinghamshire. Across Buckinghamshire, we cover New Zealand. You can also see our page for Milton Keynes.
Every address in HP19 and HP20 is within our area for electronic leak detection, from the main roads to the quietest streets. If you need electronic leak detection at a property on Dunsham Lane, Drayton Road and Cannock Road or a nearby road, we can survey it. Close by, we survey roofs in Elmhurst (1 mile east), Aylesbury (1 mile south), Watermead (1 mile north-east), Quarrendon Estate (1 mile west) and California (1 mile south). Within a short drive, we also cover High Wycombe (14 miles south), Chesham (12 miles south-east), Buckingham (14 miles north-west), Amersham (14 miles south-east), Princes Risborough (7 miles south) and Haddenham (6 miles south-west).
Near you in New Zealand
Typical jobs here are in homes near The New Zealand pub, Buckinghamshire UTC and The PACE Centre, among other places. For rail, the closest station is Aylesbury station, about 0.8 miles south. Other landmarks nearby include Royal Buckinghamshire Hospital (under half a mile south) and Dinton Castle (3.8 miles south-west).
What electronic leak detection does not cover
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Build-ups without a suitable layer below
- Water entering through details rather than the membrane
- The extent of water in the insulation

DIY checks: what’s safe
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Share it with us when you book, as it helps us focus the survey.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date.
Common roof problems in New Zealand
When the membrane is buried, holes can’t be seen at all. ELD can work on some covered roofs, depending on the build-up.
Problems we come across frequently include:
- Breaches hidden under paving or planting
- Leaks at pipes, outlets or fixings
- New roofs to check before paving or planting
- Failed seams and laps
If your home is one of the older ones in the streets near St Peter's, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
Choosing a roof surveyor
- Which viewpoints they use to see the roof
- Whether VAT is added on top
- Will they check the loft as well as the outside?
- What’s outside the scope of the survey
