Electronic leak detection for homes and businesses in Forstal
Electronic testing locates holes in the waterproofing, not every cause of water getting in. Leaks from walls, copings, rooflights or pipes need other checks. We’ll tell you if we think the leak is coming from somewhere else. It won’t show water getting in through brickwork or around frames. Our report keeps that distinction clear. You’ll also know what to check next. If you are worried about stains far from any visible defect and leaks under green or ballasted roofs, a survey will tell you what’s going on, on green roofs, single-ply roofs and commercial flat roofs alike.
In a village or hamlet like Forstal, flat roofs are normally on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them when booking.
Findings are set out part by part, from the coverings down to the gutters, with a note and a photo for each point. It records what’s sound as well as what is not.

When you need someone else
This isn’t a RICS building survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Water entering through details rather than the membrane
- Moisture spread under the membrane
- Sections we cannot safely access
If you’re not sure which survey you need, call 07833 053749 or drop us an email and we’ll give you a straight answer. What our survey covers.
What we look at
- Green roofs
- Roof terraces and balconies
- Commercial flat roofs
- Flat roof membranes
- Liquid-applied waterproofing
- Single-ply roofs
Different roofs, different checks
Inverted and paved roofs
On inverted roofs, insulation sits above the membrane, which affects testing.
Green and ballasted roofs
ELD is easier on a new roof before it is covered.
What a survey costs
When we price a survey, we consider:
- Whether thermal imaging or a drone is needed
- Commercial roofs and larger buildings
- How big the roof is
- Extensions, dormers and garages with roofs of their own
For a price for your roof in Forstal, phone 07833 053749 or use the contact form with the address and some details. The price is agreed before a date is set.

There is no need for technical words. It is enough to let us know:

- Pictures of the roof from a safe spot, if you have them

Questions from Forstal
Is Forstal within the area you cover?
Yes, we do. We survey roofs across London and South East England, from towns to the smallest villages. The journey is planned ahead, so it’s useful to know about access.
Do you carry out roof surveys in Forstal?
Yes, Forstal is one of the places we work. The survey and report are the same in Forstal as anywhere else, and visits run on weekdays and weekends.
What does electronic leak detection do?
A sound membrane blocks the test current, so wherever there’s a hole, it passes through. That’s how we locate breaches you can’t see.
Do you use drones?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.
What insurance do you have?
Every survey is covered by professional indemnity and public liability insurance.
How soon will I get the report?
That depends on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. Reports are sent by email.
Is my roof suitable for ELD?
It depends on the membrane and the build-up. Tell us what you know about the roof and we’ll check whether ELD will work.
Why get it checked now?
Repairs in the wrong place leave the leak in place. ELD shows the actual breach points. Around Forstal, older homes often have old roof timbers, where water from a failed roof can cause rot if it is left.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Why book with us
- Drone flown under a CAA Flyer ID and Operator ID
- Drone and thermal imaging surveys available
- More than 5,000 surveys completed
- Two decades and more of roof surveys

Electronic leak detection around Forstal
Older houses across Kent often have handmade clay or peg tiles, and many have tile-hung walls. The county’s older buildings also include oast houses and timber-framed Wealden hall houses. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops. With Starkey Castle about 4.4 miles north, Forstal sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
If you look after a shop, office or commercial unit, for instance near Fremlin Walk, a flat roof over a business is out of sight and out of mind until it leaks. If you live in an older home near Methodist Church Including Sunday School, flat-roofed rear additions and dormers added over the years are worth checking. Take a building like St Peter's Church of England Primary School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

How the survey works
You don’t need to do much on the day. Show us any stains, drips or problem areas you know about, and we will get on with the inspection. The survey itself takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Older roofs in small places like Forstal can have low, tight loft spaces, so it is useful to know whether there is a loft hatch and how easy it is to reach. We only go where it’s safe.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photographs shows where each breach is.
Preparing for the visit
- Jot down any questions you want answered
- Make sure we can get to the back of the property
- Point out any leaks or damp patches
How to book
If you have photos of the roof, send them over. Pictures from the ground or a window are fine. To get started, call 07833 053749 or email us.
