Electronic leak detection in Keeper's Corner from an independent, experienced roof surveyor. More than 20 years and over 5,000 surveys across London and South East England.

Do you need electronic leak detection in Keeper's Corner?
Repeated leaks after repairs suggest the real breach hasn’t been found. ELD can locate the breach more precisely.
Here are some of the things we see often:
- Leaks at pipes, outlets or fixings
- Failed seams and laps
- Repairs that haven’t stopped the leak
- Holes left by work on the roof
Anyone responsible for a site like Copthorne CofE Junior School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

About our electronic leak detection in Keeper's Corner
Electronic leak detection works on many flat roof membranes, on homes, blocks and commercial buildings. It can be used to trace an existing leak or check a new membrane before handover. We quote for each roof based on its size and build-up. We can test on weekdays and at weekends when conditions allow. Just ask about your roof. If you are worried about new roofs to check before paving or planting and breaches hidden under paving or planting, a survey will tell you what’s going on, whatever the roof.
Older buildings in small places like Keeper's Corner may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Finding out what state the roof is in gives you the facts to plan with. Listed building consent is needed for changes that affect a listed building’s special interest.
We write the report in plain English, so it makes sense without any roofing background. Each point is backed by a photograph where possible, and recommendations are put with the most urgent first where relevant.

Your questions about electronic leak detection in Keeper's Corner
Do you cover Keeper's Corner?
We do. Every survey there gets the same written report with photographs.
Does a conservation area affect roof work in Keeper's Corner?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
How experienced are you?
Over 20 years and more than 5,000 surveys.
How do you choose the testing method?
It depends on the membrane and the build-up. Low-voltage testing typically needs a wet surface and high-voltage methods need the membrane dry and exposed.
Do you survey on Saturdays and Sundays?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Tell us which days suit you when you book.
Can you survey in bad weather?
Light rain doesn’t normally stop a survey. Heavy rain or strong wind can ground a drone and make the roof unsafe, so if conditions are not right we will arrange another day with you.
What happens next?
We email you the written report with photos and recommendations. It is yours to share with a seller, insurer, roofer or managing agent, whichever applies.
When you need someone else
No survey can tell you everything, and it is better to know them up front. Keep these in mind:
- Repairing the breaches (that is for your roofer)
- Build-ups without a suitable layer below
- Leaks from plumbing or windows

Tips from our surveys
There is plenty you can do without going near the roof. Here’s what helps most:
- Ask contractors to protect the membrane
- Test new membranes before covering them
- Note where leaks show inside and when
- Tell us about the membrane and build-up if you know it
Where the evidence points to walls, copings or rooflights, we will note it, so other causes can be checked.
Act on leaks quickly. Water under a membrane can spread.
Flat and commercial roofs around Keeper's Corner
In Surrey, older roofs are often handmade clay tile, with tile-hanging on many upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Next to the main roofs there’s normally a flat roof somewhere, whether on an extension, a garage or a commercial unit. With Saint Hill Manor about 4.8 miles south-east, Keeper's Corner 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.
The streets around a church like Church of St Bartholomew are often among the oldest in a place, and if your home is one of the older ones nearby, flat-roofed rear additions and dormers added over the years are worth checking. If you own a rental within reach of Gatwick Airport station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

What affects the cost of electronic leak detection
Several things affect the price of a survey:
- The use of thermal imaging or a drone
- The height of the building and how the roof can safely be seen
- Commercial roofs and larger buildings
- How many separate roofs there are, such as extensions, dormers and garages
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before you book.
What to let us know when you get in touch
When you call or email, these details help:
- Anything about access we should know
- Pictures from the garden or a window, if you have them
- Any stains, drips or damp patches you’ve seen indoors
- The kind of building and roof involved
If you have photos of the roof, send them over. Pictures from the ground or a window are fine. To send them or to book, phone 07833 053749 or drop us an email.
What we do, step by step
Photos are taken throughout the visit, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available. A typical visit takes more time on a big roof than a small one, with the construction of the roof playing a part too. Around Keeper's Corner, older homes can have small or awkward roof spaces, so it helps to know whether there’s a loft hatch and how easy it is to reach. We only go where it is safe.
- We start by finding out what the roof is made of and where it leaks.
- We check that the membrane and build-up suit electronic leak detection.
- We pick the low-voltage or high-voltage method that suits the roof.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photos in a report for your roofer.
Before the survey
- Leave a clear route to the loft
- If the roof is shared, arrange access with whoever manages the building
- Let us know about parking before the day
