Electronic leak detection for homes and businesses in South Nutfield
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. It can find holes too small to spot by eye so your roofer knows exactly where to repair. The results come in a report with photos. We’re frequently asked to look into patched roofs that still leak and breaches around outlets and penetrations, on commercial flat roofs, roof terraces and balconies and liquid-applied waterproofing.
In a small place like South Nutfield, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, usually show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
The report records the flat roof membrane as we found it on the day. It’s useful straight away, and a good reference for later.

With a portfolio of properties, surveys can be booked for more than one address. To arrange surveys for several addresses, call 07833 053749 or send us an email with the addresses.
An agent can book and manage the survey for a landlord, and the report can go to both. We agree a time with the tenant beforehand.
Questions from South Nutfield
Is my home in South Nutfield listed or in a conservation area?
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 cover smaller places like South Nutfield?
Yes. South Nutfield is within the area we cover, which takes in towns, villages and rural addresses. We survey roofs across London and the South East. Just mention lanes, gates or anything else about the route when booking.
How much time does ELD need?
The roof’s size and build-up decide how long it takes. You will know roughly how long before we start.
Are you structural engineers?
No. We are roof surveyors, not structural engineers. We’ll recommend an engineer if we see signs that call for one.
Can you test a green or ballasted roof?
Sometimes. It depends on the build-up and the layers above the membrane, and some may need lifting. We talk this through first.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and testing are not part of what we do. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings, and recommend a specialist asbestos surveyor checks them before they’re disturbed.
Will you check the loft?
If it’s needed and safe to reach, yes. Inside, we look for damp, staining, gaps and sagging, as far as the space allows.
When you need someone else
Some things cannot be seen without opening up the roof, and that sets some limits:
- Sections we can’t safely access
- Some conductive membranes
- Moisture spread under the membrane
If in doubt, call 07833 053749 or send us an email and we’ll suggest the right survey before booking. The full list of what we check.

Electronic leak detection in South Nutfield: local notes
In Surrey, older roofs are often handmade clay tile, with tile-hanging on many upper walls. Horsham stone slab roofs survive on some old buildings in Surrey. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. If your home is older, it is worth knowing whether it is listed or in a conservation area before planning roof work. Changes that affect a listed building’s special interest need listed building consent, and councils can also use Article 4 directions to control changes in conservation areas.
For an older house near a landmark like Christ Church, the flat roofs on later extensions tend to wear out long before the main roof. For site and facilities teams at buildings like Nutfield Church CofE Primary School, a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail. If you let a flat or house near Nutfield station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

How the survey works
We’ll ask a few questions first, such as when any problem began and what work has been done before. Then the inspection itself takes a length of time set by the membrane area and the build-up, which we’ll explain when we quote. Cottages and farmhouses around South Nutfield frequently have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints.
- 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.
- The testing method is chosen to suit the membrane and build-up.
- Testing runs across the roof to locate breaches in the membrane.
- The breaches are recorded with photos in a report for your roofer.
Before the survey
- Let us know about parking near the property
- Find any records of previous roof work
- Have keys ready for side gates, garages or roof access doors

Practical tips
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Some tips:
- Check trades protect the waterproofing
- Share any drawings of the roof
- Stay off the flat roof unless needed
- Record dates and spots where water appears
The report records each breach location with photos. Pass it to your roofer to repair the breach points.
Make sure contractors protect the waterproofing when fitting equipment. Check the roof after they’ve finished.
How the survey changes by roof type
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing, which affects testing.
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer but holes and thin areas can occur. Suitability for ELD depends on the system.
Should I look at the roof myself first?
It is useful to keep a record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry, as it helps us focus the survey.
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That is where a survey comes in, using safe viewpoints and a drone where it applies.
