Electronic leak detection for homes and businesses in Chelsham
Not every flat roof suits electronic testing. Certain membranes conduct electricity, and some build-ups lack the layer the test needs below the membrane. We’ll say if ELD will not work on your roof at the start. Telling us what you know about the roof’s membrane and layers helps, including drawings, specifications or the roofer’s paperwork. It saves a wasted visit. If you’ve noticed damage from equipment installers and repairs that haven’t stopped the leak, we can find out what’s behind it, whatever the roof.
Older buildings in small places like Chelsham 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.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

Common questions in Chelsham
Is Chelsham within the area you cover?
Yes, smaller places are covered as well as towns. Our area covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
How do I find out if my home in Chelsham is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you carry professional indemnity insurance?
We hold professional indemnity and public liability insurance, for every survey we carry out.
What happens next?
You receive the written report by email, with photos and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Which days do you carry out surveys?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Let us know which days suit you when you book.
Will I get photos?
Yes. Photographs are taken throughout the survey, and the report uses them to show each finding.
Are you structural engineers?
No. We are experienced roof surveyors, and visible signs like sagging are noted, but we don’t provide calculations or an engineer’s opinion. If one is needed, the report says so.

What else we do in Chelsham
Checking the roof from the ground
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it.
Electronic leak detection in Chelsham: local notes
Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit. Addington Palace, about 3 miles north, is one of the historic houses in the wider area around Chelsham. If your house is among the older ones, expect a mix of original materials and later repairs on the roof.
Anyone responsible for a site like Warlingham Village Primary School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. For landlords with property near Woldingham station, the flat roof over a let home is worth a look before it becomes a tenant complaint. The streets around a church such as Church of St Mary the Virgin are frequently among the oldest in a place, and if your home is one of the older ones nearby, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
Chelsham is about 3 miles north-east of Caterham, in Surrey. From houses to flats and shops in Chelsham, the roof can be surveyed. Across Surrey, we cover Chelsham and the places around it. Our London page covers surveys nearby.

What happens on the day
The visit usually 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 longer on a large roof than a small one, with the construction of the roof playing a part too. Somewhere as small as Chelsham, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- You tell us about the roof and where water is showing.
- 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 photos shows where each breach is.
How to prepare

- Have any questions written down, so nothing gets missed

EPDM rubber roofs
EPDM rubber roofs often last 30–50 years, but can still be punctured.
Inverted and paved roofs
If the build-up rules out ELD, we will say so.
When you need someone else
Without opening up the roof, some things stay hidden, so a survey has limits:
- Moisture spread under the membrane
- Some conductive membranes
- Leaks from plumbing or windows
