Electronic leak detection in Canewdon: what you get
ELD suits many waterproofing membranes on flat roofs over offices, units, blocks of flats and homes. It helps trace a leak you already have or to test a new membrane before it’s covered. 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. We survey single-ply roofs, flat roof membranes and liquid-applied waterproofing, and the problems we’re asked to look at most are water coming in under a flat roof and holes left by work on the roof.
Some older homes in villages like Canewdon are 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. 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.
It is not only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

Should I look at the roof myself first?
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
The survey, step by step
On the day, we start by asking what you’ve noticed and what you need to know. We then inspect everything that can be seen safely. The survey normally takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. For a village or hamlet like Canewdon, the journey is planned ahead of time: let us know about lanes, gates and parking. 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.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
How to prepare
- Note where any stains or damp appear
- Agree roof access with the managing agent if it’s shared
- Let us know about parking before the day
Booking a survey
If you’re buying, it helps to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just call 07833 053749 or use the contact form when you’re ready.

Electronic leak detection in Canewdon: local notes
England has around 10,000 conservation areas and about 500,000 listed buildings. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material, so the council is the place to ask. In Essex, older buildings are often clay-tiled, many with weatherboarding, while many towns grew with post-war and newer estates. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For an older house near a landmark like Church of St Nicholas, the joins between later flat roofs and the old walls are where problems normally start. If you look after a building like King Edmund School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. Landlords with a home close to Althorne station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.

Tips from our surveys
A little preparation and a few simple habits help. Some pointers:
- Do not leave water getting in
- Keep outlets clear of debris
- Tell us about the membrane and build-up if you know it
- Record dates and spots where water appears
You receive a report showing where each breach was found, with photographs. Pass it to your roofer to repair the breach points.
Act on leaks quickly. Water under a membrane can spread.
Your questions about electronic leak detection in Canewdon
Do you cover Canewdon?
We do. The survey and report are the same in Canewdon as anywhere else, and visits run on weekdays and weekends.
How do I find out if my home in Canewdon is listed?
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.
What does electronic leak detection do?
ELD passes a small electrical current across the roof to locate holes in the membrane. The current only gets through where the membrane is breached so we can pinpoint it.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We look at the roof, not the whole building, and it isn’t a RICS Level 2 or Level 3 survey. Many buyers have both.
Do you climb onto every roof?
Only where it’s safe to do so. We inspect everything that’s safely in view: from ground level, from windows, from inside the roof space, from the roof where it’s safe and by drone where it applies. The report says if anything couldn’t be seen.
What will the report tell me?
It sets out what we found, why it matters and what we recommend, with photographs throughout. Anything we couldn’t see safely is noted too.
Are you insured?
Professional indemnity and public liability insurance cover our surveys. If you need details for a managing agent or a building owner, just ask.

Why it’s worth a survey now in Canewdon
Chasing a leak again and again is frustrating. A clear record of where the breaches are helps break that cycle. Older and listed buildings around Canewdon may need consent and matching materials for repairs, so a defect found early gives time to plan the work properly.
The cost of a survey depends on the roof: 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 book with us
- Surveys on weekdays, Saturdays and Sundays
- Drone and thermal imaging surveys available
- An independent view of the roof
- 20+ years’ experience

Landlord and commercial surveys in Canewdon
Shared roofs need a little more planning: we need access agreed with the freeholder or managing agent. Tell us about it when booking and we’ll plan the visit with that in mind.
We survey roofs for letting agents and landlords as well as householders. A written report with photos gives you a clear record of the flat roof membrane.
What electronic leak detection doesn’t cover
Some things cannot be seen without opening up the roof, so a survey has limits:
- Build-ups without a suitable layer below
- Parts of the roof covered by fixed equipment
- Leaks from plumbing or windows
