Electronic Leak Detection in Chevening
A careful look at the flat roof membrane at your property in Chevening, with photos and a written report.
- Damp inside with no sign on the roof
- Leaking laps in the waterproofing

- Carrying out the repair work
- Roofs whose membrane or build-up is not suitable
- Parts of the roof covered by fixed equipment

About our electronic leak detection in Chevening
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. A retest after repairs can check the work if the build-up allows. Results come in a written report with photos. We survey commercial flat roofs, roof terraces and balconies and green roofs, and the problems we are asked to look at most are breaches around outlets and penetrations and new roofs to check before paving or planting.
In a small place like Chevening, 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. 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.
What you get is a clear record of the flat roof membrane on the day we saw it. It’s useful right away, and a good reference for later.

The survey, step by step
We photograph the roof as we go, so you can see in the report what we found and where. We take close-ups from wherever is safe, including by drone where it is applicable and the weather allows. Most surveys take as long as needed for the size of the roof and how it’s built, which we’ll explain when we quote. Somewhere like Chevening needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. On the day, we inspect whatever is safely visible, inside and out.
- First, you let us know about the roof build-up and where water is showing.
- We check that the membrane and build-up suit electronic leak detection.
- We pick the low-voltage or high-voltage method that suits the roof.
- Testing runs across the roof to locate breaches in the membrane.
- We send a report with photos of each breach so your roofer can repair it.
Before we arrive
- If it isn’t your property yet, arrange access through the agent
- Have keys ready for side gates, garages or roof access doors
- Clear the way to the loft hatch

Rented homes, blocks and businesses
An agent can book and manage the survey for a landlord, with the report sent to whoever needs it. We agree a time with the tenant beforehand.
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out by urgency where it matters, which helps with budgets and planning.
What affects the cost of electronic leak detection
Every roof is different, so prices are confirmed before booking. These are the things that affect it:
- The size of the roof
- The type of building, from a house to a block or an office
- The number of roofs, including extensions and garages
- The use of thermal imaging or a drone
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You will know the exact price before you book.
Getting in touch
The more you let us know, the easier it is to price the survey. When you contact us, tell us:
- The type of building and roof, such as pitched or flat
- Your timetable, such as an exchange date
- Where water is showing inside, if it is
- Pictures from the garden or a window, if you have them
Our phone lines are open seven days a week, including Saturdays and Sundays. For a price or to book, ring 07833 053749 or email us.
Do you need electronic leak detection in Chevening?
Seams are a common weak point in flat roof waterproofing. Small openings at laps can leak long before anyone notices.
A survey makes sense if you’ve noticed:
- Leaks that return after repairs
- New roofs to check before paving or planting
- Holes left by work on the roof
- Holes around roof penetrations
For landlords with property near Dunton Green station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Choosing a roof surveyor
- What the survey will not cover
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- How soon the report will arrive
- Whether you get a written report with photos

What else we do in Chevening
Flat roofs in Chevening
The wider area around Chevening has a long history of building, with Quebec House about 3.3 miles south-west. On older houses around here, roofs frequently 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. Handmade clay tiles, including Kent peg tiles hung on pegs through two holes, are typical of older Kent buildings. Kent’s older buildings take in oast houses and timber-framed Wealden hall houses as well. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
The streets around a church such as Church of St Botolph are frequently among the oldest in a place, and if yours is one of the older homes nearby, flat-roofed rear additions and dormers added over the years are worth checking. For site and facilities teams at buildings like Combe Bank School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

Your questions about electronic leak detection in Chevening
Does a conservation area affect roof work in Chevening?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Do you cover Chevening?
Yes. We work right across London and the South East, and Chevening is part of that. You can call 07833 053749 or drop us an email with the address and some details, and we’ll talk through which survey suits.
Does someone need to be in?
Not always. An outside-only look can be arranged beforehand, but anything inside needs someone there to give access.
Will you go up on the roof?
Not unless it is safe. Most of what we need can be seen from safe viewpoints, the loft and, where applicable, a drone, and the report notes anything we couldn’t see.
Can you test a green or ballasted roof?
Sometimes. It depends on the build-up and the layers above the membrane, and some may need lifting. We talk this through first.
Will you check the loft?
If the survey needs it and the roof space can be reached safely, yes. Please clear anything stored under the hatch.
Is this a RICS survey?
No. Our survey looks at the roof, not the whole building. If you need a full building survey, you will need a RICS survey as well.
Leave it or get it looked at?
Repairs in the wrong place leave the leak in place. ELD shows the actual breach points. For an older or listed building in a place like Chevening, repairs may need matching materials and consent, so leaving a defect until it’s urgent leaves less time to plan.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before booking.
