A survey is a close look at the flat roof membrane, but it can’t do everything. The main limits are:
- How wet the insulation is
- Sections we can’t safely access
- Some conductive membranes

How electronic leak detection works in Chaldon
Not every flat roof suits electronic testing. Certain membranes conduct electricity and some roofs don’t have a suitable layer beneath the membrane. If your roof is not suitable, we’ll tell you at the start. Any details you have about the membrane and build-up help us decide, such as drawings or specifications. It saves a wasted visit. Typical surveys look at stains far from any visible defect and leaks at pipes, outlets or fixings, on single-ply roofs, liquid-applied waterproofing and green roofs.
Somewhere as small as Chaldon, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: outlets, upstands, edges and the covering itself. We simply plan the journey and access ahead of time. If there are outbuildings or garages with flat roofs, mention them as you book.
Nothing in the report is left vague: if work is needed, the report says so clearly.

Useful tips for Chaldon property owners
Nothing here needs a ladder. Our suggestions:
- Tell us about the membrane and build-up if you know it
- Check new waterproofing before handover
- Limit access to the roof
- Keep outlets clear of debris
If we think the leak is not coming through the membrane, the report says so, so other causes can be checked.
Limit foot traffic on flat roofs. Feet and dropped tools are a common cause of holes.
Chaldon questions
Is my home in Chaldon listed or in a conservation area?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
Is Chaldon within the area you cover?
Yes. Chaldon 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 you book.
What does electronic leak detection do?
A sound membrane blocks the test current, but a hole lets it through. That’s how we locate breaches you can’t see.
Can you test a green or ballasted roof?
In some cases. The layers on top and the build-up below decide it, and some may need lifting. We will discuss it before we quote.
Is my roof suitable for ELD?
Not every roof is suitable. Some membranes conduct electricity and some roofs lack the layer the test needs. We’ll tell you if yours is not suitable before testing.
What’s the best way to book?
To book, phone 07833 053749 or email us with the address, the type of property and what’s prompted the survey. We will confirm the price and agree a day with you.
How soon will I get the report?
Report times are set by the package. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. If you have a deadline, such as an exchange date, tell us when you book.
What happens on the day
There is not much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll take it from there. The survey itself takes longer on a large roof than a small one, with the construction of the roof playing a part too. For a village or hamlet like Chaldon, the journey is planned beforehand: tell us about narrow lanes, gates, long drives and where we can park. The roof is looked at from the ground, from windows, from the loft where there’s safe access and from the roof where it is safe.
- 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 photographs shows where each breach is.
Before we arrive
- Show us where any leaks or stains appear
- Make sure we can get to the back of the property
- If you’re buying, check with the agent that we can get in
Arrange a survey
Photos help, if you have them. Take them safely from ground level or a window, and please don’t climb up for a closer look. To get started, ring 07833 053749 or drop us an email.
Related advice
Flat roofs in Chaldon
Listing and conservation areas can both shape what roof work is allowed on an older home. The council is the place to check, along with Historic England’s list. 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. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
The streets around a church such as Church of St Peter and St Paul are frequently among the oldest in a place, and if your house is among 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. If you own a rental within reach of Caterham station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. Anyone responsible for a site like St Peter and St Paul CofE Infant School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

What we look for on each type of roof
Bituminous membranes
Bituminous roofs often have laps and old repairs that can leak. Testing depends on the roof.
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer, but can still have thin spots or holes. Whether ELD works depends on the coating and build-up.
Rented homes, blocks and businesses
We also survey roofs for businesses and commercial landlords, including offices, shops and units. Bigger roofs take more time, so they’re priced to suit.
Surveys can also be booked by buyers’ agents acting for a client. Reports are emailed, so they’re easy to pass on, photographs included.
What affects the price in Chaldon
To price your survey, we check:
- Whether it is a home or a commercial building
- The shape of the roof and its details
- Extra roofs, like extensions, dormers or garages
- The roof’s overall size
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You will know the figure before booking.
Helping us price your survey
There is no need for technical words. It’s enough to let us know:
- Access details, such as a loft hatch or a shared roof
- What kind of property and roof it is
- Your timetable, such as an exchange date
- Photos of the roof, taken safely from the ground or a window
