Electronic Leak Detection in Betsham
Electronic leak detection to pinpoint holes in flat roof membranes in Betsham. We have completed more than 5,000 surveys across London and the South East.
- Leaking laps in the waterproofing
- Repairs that haven’t stopped the leak
- A flat roof leak that can’t be traced
About our electronic leak detection in Betsham
There are different ELD methods. Low-voltage testing is usually done with the surface wet, while high-voltage testing needs a dry, exposed membrane. Which one suits depends on the membrane and the layers of the roof and we explain which we will use. We’ll say if your roof doesn’t suit either method before any testing starts. Common reasons to book are breaches hidden under paving or planting and punctures from foot traffic or tools, across roof terraces and balconies, single-ply roofs and liquid-applied waterproofing.
Older buildings in small places like Betsham may be listed or in a conservation area, which can shape what a new flat roof may look like. If you are planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
Nothing in the report is left vague: if work is needed, the report says so clearly.

Useful tips for Betsham property owners
A little preparation and a few simple habits help. Our tips:
- Ask contractors to protect the membrane
- Don’t let outlets block
- Don’t leave water getting in
- Don’t keep patching the same spot
File the report with your roof paperwork. It shows the condition of the membrane on that date.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.
How the survey changes by roof type
Green and ballasted roofs
Parts of the covering may have to come up. We discuss this before quoting.
EPDM rubber roofs
Whether an EPDM roof can be tested depends on the membrane and build-up. We check before we quote.
Flat roofs in Betsham
Betsham lies within about 4 miles of the sea, and being near the sea means more wind and salt than a roof inland would face. Wind can catch loose edges and trims on a flat roof, and salt air is hard on metal trims, flashings and fixings. With Cobham College about 4.4 miles south-east, Betsham 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 the council can say whether a home is in a conservation area.
For landlords with property near Longfield station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. Anyone responsible for a site like Sedley's Church of England Voluntary Aided Primary School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

Leave it or get it looked at?
Leaks left running can wet the insulation and deck. Locating it early helps limit the damage. Matching old materials, like handmade tiles or stone slates, can take time to source. Spotting a problem early leaves room to find them.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You will know the figure before booking.

Betsham: your questions answered
Is the coastal weather around Betsham hard on roofs?
Places near the sea get more wind and more salt in the air than inland, and both are hard on roofs. Salt is hard on nails, clips and metal flashings, while strong wind lifts anything already loose.
Does a conservation area affect roof work in Betsham?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
What’s the best way to book?
It is easiest to phone 07833 053749 or drop us an email. Let us know the address and a little about the roof, and we will take it from there. We survey on weekdays and at weekends.
How soon will I get the report?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. Each one is emailed.
Do I need to be at home?
Not always. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
What’s in the survey report?
It explains what we saw, what it means and what we’d suggest, with photographs throughout. It also says if any part of the roof couldn’t be seen safely.
Can you survey a shared roof?
Yes, if whoever owns or manages the building agrees access. On a shared roof we can only inspect the parts we’re allowed to reach, and the report makes that clear.
How the survey works
The visit typically starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. In total, it takes more time on a big roof than a small one, with the construction of the roof playing a part too. Somewhere like Betsham needs a little journey planning: let us know about narrow lanes, gates, long drives and where we can park. On the day, we inspect what can safely be seen, inside and out.
- You tell us about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photos shows where each breach is.
Getting ready for the survey
- Agree roof access with the managing agent if it is shared
- Leave side gates unlocked
- If you are buying, let the agent know when we are coming
Getting a price
Photos help, if you have them. Pictures from the ground or a window are fine. To send them or to book, phone 07833 053749 or send us an email.
Advice
Do you need electronic leak detection in Betsham?
New membranes can have defects from installation. ELD on a new roof can show holes before they cause leaks.
We are frequently asked to look at:
- Water coming in under a flat roof
- Repairs that haven’t stopped the leak
- Stains far from any visible defect
- Waterproofing to test before it’s covered
If you look after a shop, office or commercial unit, for example near Bluewater, a flat roof over a business is out of sight and out of mind until it leaks.
Questions to ask before booking
- Their track record with similar roofs
- What happens after the report arrives
- Whether the roof space is looked at, where there is one
- Will the report include photos?
