About our electronic leak detection in Dawesgreen
Water can travel under a flat roof membrane before it shows inside. So the stain inside rarely sits under the hole. ELD tests the waterproofing directly, to find where it has been breached. It is testing only and leave the repair to your roofer. On a suitable roof, it takes the guesswork out of finding the hole. We then send you the results in a written report. If you’re worried about damp inside with no sign on the roof and holes left by work on the roof, we can find out what’s behind it.
In a small place like Dawesgreen, a flat roof can stand in the open, so edges, upstands and laps take a beating. Older felt roofs, often around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. On an exposed roof, the edges tend to go first.
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.

What affects the cost of electronic leak detection
We confirm the exact price before booking. This is what makes a difference:
- Any need for thermal images or a drone flight
- Extensions, dormers and garages with roofs of their own
- The type of building, from a house to a block or an office
- Roof area
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You will know the figure before booking.
Booking your survey
We will typically ask about:
- Photos of the roof, taken safely from ground level or a window
- Where water is showing inside, if it is
- The kind of building and roof involved
- When you need the report by
If you’re buying, it’s useful to book soon after your offer is accepted, so there is time to use the report before exchange. For any other survey, just call 07833 053749 or use the contact form when you are ready.
What electronic leak detection looks like in Dawesgreen
Handmade clay tiles and tile-hung walls are typical of Surrey’s older houses. 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. 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.
Anyone responsible for a site like Burys Court School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. Landlords with a home close to Betchworth station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.

What we’re asked to look at in Dawesgreen
Other trades on the roof can puncture the waterproofing. Engineers fitting equipment, solar panels or aerials may leave damage behind.
These are some of the problems a survey can pick up:
- Failed seams and laps
- Repairs that haven’t stopped the leak
- New membranes needing a check before handover
- Holes left by work on the roof
If you own one of the older houses in the streets near Church of St Bartholomew, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
What to check before booking
- Whether any drone flown is registered with the CAA
- What insurance they carry
- Whether you get a written report with photos
- What happens after the report arrives
How the survey works
We photograph the roof as we go, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available, including by drone where it’s applicable and the weather allows. A typical visit takes more time on a big roof than a small one, with the construction of the roof playing a part too. Somewhere like Dawesgreen needs a little journey planning: let us know 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 is 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.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photos shows where each breach is.
Before the survey
- If the roof is shared, arrange access with whoever manages the building
- Leave side gates unlocked
- Clear the way to the loft hatch

How do I find out if my home in Dawesgreen is listed?
The council and Historic England’s list are the places to check. It is worth checking before planning roof work, as both can affect what’s allowed.
Do you take photos of the roof?
Yes, every report has them. Pictures sit next to the findings they show, which makes the report easy to follow.
What does the report include?
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, so you know exactly what was covered.
Do I need to be at home?
Someone needs to let us in if we’re looking inside or in the loft. Access is agreed with you as you book.
What do I do with the report?
The report comes by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Does ELD work under paving or planting?
On some roofs, yes. What sits on the membrane affects the method, so we check the build-up first.
