Flaunden Electronic Leak Detection
An experienced roof surveyor for electronic leak detection in Flaunden. Over 5,000 surveys and 20+ years behind us across London and South East England.
- Leaks through a flat roof with no obvious cause
- Gaps at membrane joints
- Leaks showing away from the breach
Before and after the survey
Most of what helps is simple and safe from the ground. Our suggestions:
- Find the breach before more patching
- Do not let outlets block
- Stay off the flat roof unless needed
- Get leaks traced quickly
After your roofer repairs the breaches, a retest can confirm them if the build-up allows.
Ask trades working on the roof to protect the membrane when they work up there. Check the roof after they’ve finished.
Electronic leak detection in Flaunden: what you get
You get a report showing the location of each breach, with photos. Your roofer can then repair those points rather than guessing. Repair costs are not part of the report, so your roofer prices the work. Testing again after repairs can confirm the breaches have been dealt with if the build-up allows. You get a written report with photos. We survey single-ply roofs, liquid-applied waterproofing and commercial flat roofs, and people most often book us about patched roofs that still leak and leaks showing away from the breach.
In a small place like Flaunden, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Older felt roofs, often around 15–20 years in life, 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.
It isn’t 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.

Checking the roof from the ground
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date.
It is useful to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us as you book and it will help the survey.
What this survey cannot tell you
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Water entering through details rather than the membrane
- How wet the insulation is
- Fixing the holes we find
If in doubt, phone 07833 053749 or send us an email and we’ll recommend the right survey before you book. What a survey covers and does not.

How we price electronic leak detection
The price reflects the time and kit the roof needs. That comes down to:
- The height of the building and how the roof can safely be seen
- The type of building, from a house to a block or an office
- The number of roofs, including extensions and garages
- Roof area
For a price for your roof in Flaunden, ring 07833 053749 or use the contact form and tell us about the roof. We’ll confirm the figure before booking.

The more you let us know, the easier it is to price the survey. When you contact us, let us know:

- Pictures of the roof from a safe spot, if you have them
- How the loft is reached, if there is one
- Where any leaks, stains or damp patches show inside
Photos help, if you have them. Take them safely from the ground or a window. To send them or to book, ring 07833 053749 or use the contact form.

Questions from Flaunden
Is Flaunden in the area you cover?
Yes, Flaunden is within the area we cover. We cover the whole of London and South East England. Just ring 07833 053749 or email us and let us know about the property, and we will talk through which survey suits.
How do I find out if my home in Flaunden is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
What if it rains on the day?
It can, depending on the survey. Drone flights need calm, dry weather, and thermal imaging works best after a sunny day, with a dry roof and little wind. We will rearrange with you if the weather is not right.
How is ELD priced?
We quote for each roof individually. Tell us about the roof and where it leaks. Just ring 07833 053749 or use the contact form for a quote.
Is this a RICS survey?
No. It’s a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
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. Reports are sent by email.
Are you insured?
Every survey is covered by professional indemnity and public liability insurance.
Flat roofs in Flaunden
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, with flat-roofed extensions, dormers and garages common everywhere. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. Chenies Manor House, about 1.6 miles south, is one of the historic houses in the wider area around Flaunden. Older homes in the wider area frequently have features worth a closer look, like 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.
Anyone responsible for a site like St Clement Danes School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. If you own a rental within reach of Chalfont & Latimer station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. If you live in an older home near Church of St Mary Magdalene (Church of England), later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.

What we do, step by step
We photograph the roof as we go, so the report shows exactly what we saw. We take close-ups from wherever is safe. A typical visit takes more time on a big roof than a small one, with the construction of the roof playing a part too. In a small place like Flaunden, access is normally the main thing to plan. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
Preparing for the visit
- Note where any stains or damp appear
- Have any questions written down, so nothing gets missed
- Check we can get to the back of the property
