About our electronic leak detection in Four Elms
Roofs covered with paving, ballast or planting need more thought. The layers on top can limit the methods we can use, and some may need lifting. We will discuss it with you when we quote. Any details of the build-up help, as they show what lies beneath the surface. If testing isn’t possible, we’ll say so. If you are worried about punctures from foot traffic or tools and damp inside with no sign on the roof, we can find out what’s behind it.
Flat roofs on exposed homes in small places like Four Elms take more wind and rain, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, typically show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are usually the first part of a flat roof to go.
The report records the flat roof membrane as we found it on the day. It is useful straight away, and a good reference for later, such as when you want to compare after future work.

Flat roofs in Four Elms
Older houses across Kent frequently have handmade clay or peg tiles, and many have tile-hung walls. You’ll also find oast houses and timber-framed Wealden hall houses among the county’s older buildings. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. With Chartwell about 2 miles north, Four Elms sits in an area with a long building history. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.
If you live in an older home near Congregational Church, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. If you let a flat or house near Edenbridge station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. Anyone responsible for a site like Four Elms Primary School will know that a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.

Four Elms: your questions answered
Do you carry out roof surveys in Four Elms?
We do. The survey and report are the same in Four Elms as anywhere else.
Do you cover smaller places like Four Elms?
Yes, Four Elms is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
What happens after the survey?
We email you the written report with photographs and recommendations. It is yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Can you survey at the weekend?
We survey seven days a week: Monday to Friday, Saturdays and Sundays. Just let us know the days that suit you.
How much time does ELD need?
It depends on the size of the roof and its build-up. You will know roughly how long before we start.
Will you fly a drone over my roof?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
Does the report include photos?
Yes. Photos are part of every report, so you can see each point for yourself.
How the survey works
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. You’re welcome to ask questions while we are there. In a small place like Four Elms, access is usually the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.

- We get the roof ready for testing.
- Testing runs across the agreed area.

Should I look at the roof myself first?
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
The one thing to avoid is getting up close. Roofs are fragile and slippery. That’s where a survey comes in.
Prices for electronic leak detection in Four Elms
All our prices include VAT. What changes the price is:
- Any need for thermal images or a drone flight
- Height and safe access
- Features like valleys, chimneys, dormers and parapets

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.
Helping us price your survey
You don’t need to know any roofing terms. Just let us know:
- Why you want a survey: buying, a leak, a storm or new work
- Any marks or damp showing indoors
- The kind of building and roof involved
- Anything about access we should know
Booking is simple: just phone 07833 053749 or use the contact form, let us know about the property and we will point you to the right survey. We confirm the price before anything is booked.
Leave it or get it looked at?
Patching where you think the leak is often misses it. ELD shows the actual breach points. Older cottages and farmhouses around Four Elms can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it is left.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before you book.
What you get with us
- Drones and thermal imaging where applicable
- Visits on any day of the week
- Covered by professional indemnity and public liability insurance
