About our electronic leak detection in New Denham
Not every flat roof suits electronic testing. Some membranes conduct electricity themselves, and some build-ups lack the layer the test needs below the membrane. If your roof isn’t suitable, we will tell you at the start. Any details you have about the membrane and build-up help us decide, such as drawings or specifications. It avoids arranging a test that cannot give results. We survey liquid-applied waterproofing, roof terraces and balconies and single-ply roofs, and people most often book us about leaks showing away from the breach and leaks through a covered membrane.
In a small place like New Denham, 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. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are normally the first part of a flat roof to go.
What you get is a clear record of the flat roof membrane on the day we saw it. It is useful right away, and a good reference for later.

What we’re asked to look at in New Denham
Roofs covered with paving, ballast or planting hide the membrane. ELD can work on some covered roofs, depending on the build-up.
Common reasons to book include:
- Punctures from foot traffic or tools
- Stains far from any visible defect
- New roofs to check before paving or planting
- Water coming in under a flat roof
Shop and office owners around The Pavilions may find that a flat roof over a business is out of sight and out of mind until it leaks.
Before you book any roof surveyor
- What insurance they carry
- What the report includes, and whether it has photographs
- Is VAT included in the price?
- What the survey will not cover
Flat and commercial roofs around New Denham
Ickenham Hall, about 2.1 miles east, is one of the historic houses in the wider area around New Denham. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material. Some villages in Buckinghamshire still have thatched roofs. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Take a building like Hermitage Primary School: 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 St Francis, the flat roofs on later extensions tend to wear out long before the main roof.

What happens on the day
We do not take risks to get a closer look. Everything that can be seen safely is inspected, and if part of the roof can’t be seen, the report says so. The survey usually takes a length of time set by the size of the roof and how it’s built, which we set out in the quote. Rural addresses near New Denham can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- The roof is assessed to see if electronic testing will work on it.
- We pick the low-voltage or high-voltage method that suits the roof.
- Testing runs across the roof to locate breaches in the membrane.
- The breaches are recorded with photographs in a report for your roofer.
How to prepare
- Let us know about parking near the property
- Check we can get to the back of the property
- Keep pets out of the way during the survey

What happens if roof problems are left?
Water trapped under a membrane can soak insulation and decking. Finding the breach sooner limits that. For an older or listed building in a place like New Denham, repairs may need matching materials and consent, so leaving a defect until it is urgent leaves less time to plan.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.

Practical tips
These tips come from what we see on roofs every week:
- Use boards when working on the roof
- Act on new leaks promptly
- Limit access to the roof
- Note where leaks show inside and when
If we think the leak is not coming through the membrane, the report says so, so other causes can be checked.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.

What affects the cost of electronic leak detection
To price your survey, we look at:
- The shape of the roof and its details
- Commercial roofs and larger buildings
- How many separate roofs there are, like extensions, dormers and garages
- Height and safe access
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before you book.

These details help when you get in touch:
- The style of property, from a terrace to a block
- Any stains, drips or damp patches you’ve seen indoors
- What made you get in touch

To arrange a survey, call 07833 053749 or send us an email and let us know the address and what’s prompted the survey. We will confirm the price before you book.
Rented homes, blocks and businesses
Shared roofs need a little more planning: we need access agreed with the freeholder or managing agent. Mention it when you contact us and we will plan the visit with that in mind.
Businesses and commercial landlords can book us too, including offices, shops and units. Larger roofs take longer, and they’re priced for the size.
