About our electronic leak detection in Brockham
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small electrical current that passes through the membrane only where there’s a breach. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. The results come in a report with photos. We are frequently asked to look into leaks at pipes, outlets or fixings and damage from equipment installers, on single-ply roofs, green roofs and liquid-applied waterproofing.
Older buildings in small places like Brockham may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you are planning work, check with the council first. Knowing the roof’s condition is the starting point. Listed building consent is needed for changes that affect a listed building’s special interest.
The report does not just list problems. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

Tips from our surveys
Here are a few things we’d tell any owner:
- Tell us about the membrane and build-up if you know it
- Limit access to the roof
- Keep a note of leaks after rain
- Keep outlets clear of debris
File the report with your roof paperwork. It shows the condition of the membrane on that date.
Consider testing a new membrane before it is covered. Finding breaches is simpler at that stage.

What happens on the day
Photographs are taken throughout the visit, so the report shows exactly what we saw. We take close-ups from wherever is safe. A typical visit takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. In a small place like Brockham, access is typically the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- We agree the area to be tested.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
How to prepare
- Make sure pets are kept safely away
- Agree roof access with the managing agent if it’s shared
- Note where any stains or damp appear

Electronic leak detection in Brockham: local notes
Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. Horsham stone slab roofs survive on some old buildings in Surrey. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. About 4.2 miles west lies Polesden Lacey, a reminder of how long the area around Brockham has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area.
If your house is among the older ones in the streets near Christ Church, the joins between later flat roofs and the old walls are where problems typically start. If you own a rental within reach of Betchworth station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. Anyone responsible for a site like North Downs Primary School will know that a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.
Brockham is about 2 miles east of Dorking, in Surrey. Whether the building in Brockham is a house, a flat or a commercial unit, we can survey the roof. Our Surrey coverage includes Brockham and the places around it. For surveys nearby, see our Crawley page.
Surveys in RH3 are booked the same way as anywhere else. Whether your property is on Holly Close, Nutwood Avenue and Kiln Lane or anywhere close by, we can survey it. If you’re just outside Brockham, we cover Betchworth (1 mile north-east), Strood Green (1 mile south), Box Hill (1 mile north), Buckland (1 mile east) and Bunce Common (2 miles south). We also work in nearby towns such as Guildford (13 miles west), Woking (14 miles north-west), Epsom (7 miles north), Horley (6 miles south-east), Redhill (5 miles east) and Ewell (8 miles north).
Landmarks near Brockham
In Brockham, that means homes and buildings near The Ashcombe School, Pippbrook House and Inn on The Green and the streets around them. The closest station to Brockham is Betchworth station, about 1.1 miles north-east. Other landmarks nearby include Reigate Priory Museum (3.3 miles east) and Headley Court (3.9 miles north). Green spaces nearby include Reigate Heath and Box Hill.
What happens if roof problems are left?
Leaks left running can wet the insulation and deck. Finding the breach sooner limits that. Matching old materials, such as handmade tiles or stone slates, can take time to source. That is one more reason to find defects before they become urgent.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Why us?
- We hold a CAA Flyer ID and Operator ID

Common questions in Brockham
Is Brockham in the area you cover?
We do. Every survey there gets the same written report with photos.
Is my home in Brockham listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
How do I arrange electronic leak detection in Brockham?
Simply ring 07833 053749 or email us with the address. We will ask a few questions, confirm the price and agree a date.
Do you take photos of the roof?
Yes, plenty. Each finding is shown in a picture where possible, which makes the report easy to follow.
Does someone need to be in?
Not necessarily. An outside-only look can be arranged beforehand, but anything inside needs someone there to give access.
Is this a RICS survey?
No. We check the roof, not the whole building, so it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
Do you survey on Saturdays and Sundays?
Visits run seven days a week in the daytime, which suits people who work during the week. Just say which days work for you.
Different roofs, different checks
Liquid-applied waterproofing
What lies under a liquid coating decides if ELD will work.
Single-ply membranes
Some single-ply membranes suit electronic testing well, depending on the type and build-up.
What affects the cost of electronic leak detection
Prices always include VAT. What changes the price is:
- Features like valleys, chimneys, dormers and parapets
- The type of building, from a house to a block or an office
- Any need for thermal images or a drone flight
- The number of roofs, including extensions and garages
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before booking.
Booking your survey
Here’s what helps us most when you contact us:
- Your timetable, such as an exchange date
- Whether there’s a loft hatch, a shared roof or tricky access
- Where the property is, with the postcode
- Photos of the roof, taken safely from ground level or a window
Getting a price is simple: just call 07833 053749 or use the contact form, tell us about the property and we will recommend the right survey. We confirm the price before anything is booked.
What electronic leak detection does not cover
Without opening up the roof, some things stay hidden, and that sets some limits:
- Parts of the roof covered by fixed equipment
- Fixing the holes we find
- How wet the insulation is
