About our electronic leak detection in Hartley
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It works with an electrical current which can only get through the membrane at a breach. That lets us locate holes that are too small to see, so your roofer can repair them. The results come in a report with photos. If you’ve noticed failed seams and laps and leaks showing away from the breach, we can find out what’s behind it, whatever the roof.
In a smaller place like Hartley, some flat roofs sit in the open, so wind catches loose edges and trims. Felt and bitumen also age in strong sun. Splits, blisters and lifting edges are what to look out for, along with water that sits after rain. Standing water that lingers for days after rain is another sign worth watching for.
We keep jargon out of it: if work is needed, the report says so clearly, and where it can wait, that’s said too.

What we’re asked to look at in Hartley
New membranes can have defects from installation. Testing before the roof is covered or handed over helps find them.
We’re often asked to look at:
- Leaks showing away from the breach
- A flat roof leak that cannot be traced
- New membranes needing a check before handover
- Breaches hidden under paving or planting
Shop and office owners around Bluewater may find that a flat roof over a business is out of sight and out of mind until it leaks.

Why get it checked now?
Opening up a roof to hunt for a leak is disruptive. Electronic testing finds the hole first so your roofer knows where to work. Around Hartley, leaves and moss in gutters lead to overflowing water and damp walls, particularly where trees overhang. Dealing with the cause is simple; drying out a wall is not.
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 it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
Why us?

Electronic leak detection in Hartley: local notes
Historic houses such as Cobham College, about 3.9 miles east, show how far back building in the area around Hartley goes. 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. 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. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
Take a building like Hartley Primary Academy: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. For landlords with property near Longfield station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

If there are outbuildings or garages you want looked at, mention them.

Your questions about electronic leak detection in Hartley
How do I find out if my home in Hartley is listed?
We can’t confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Is Hartley within the area you cover?
Yes, we do. We cover the whole of London and South East England, from towns to the smallest villages. Longer journeys are simply planned in advance.
How long will testing take?
Testing typically takes more time on a big roof than a small one, and the build-up of the roof makes a difference too.
What does the report include?
It sets out what we found, why it matters and what we recommend, backed by photos. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
Do you use drones?
Where it helps and it is safe, yes. Flights depend on the weather on the day and airspace rules, and we check for restrictions near airports before flying. We’re a CAA-registered drone operator.
Do I need to be at home?
If the survey includes the loft or the inside of the building, someone needs to let us in. We will talk about access when booking.
How do you choose the testing method?
We choose the method that suits the roof. You will know which method we plan to use before we start.
Checking the roof from the ground
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, as it helps a surveyor trace the cause.
What you can’t do safely is get up close. Roofs are fragile and slippery, and falls from height are serious. That is where a survey comes in, using safe viewpoints and a drone where it applies.
