Electronic leak detection for homes and businesses in Westhumble
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It can be used to trace an existing leak or to test a new membrane before it is covered. Each roof is quoted on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays when conditions allow. Just ask about your roof. If you’ve noticed holes around roof penetrations and damage from equipment installers, a survey will tell you what’s going on, on flat roof membranes, green roofs and liquid-applied waterproofing alike.
Flat roofs on exposed homes in small places like Westhumble take more wind and rain, so edges, upstands and laps take a beating. Older felt roofs, frequently around 15–20 years in life, 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 is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

Local flat roofs in Westhumble
There are several hotels within about a mile and a half of Westhumble. If you look after one, a leak through a flat roof can put a room out of use. About 1.8 miles west lies Polesden Lacey, a reminder of how long the area around Westhumble has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
For hotels and guest houses around Westhumble, a roof problem found early is far less disruptive than one found by a guest. Anyone responsible for a site like The Ashcombe School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. If you let a flat or house near Box Hill & Westhumble station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

Leave it or get it looked at?
A visual inspection can miss tiny holes. Electronic testing can find breaches you can’t see by eye, on suitable membranes. In a place like Westhumble, a barn or garage roof left to fail puts whatever is inside at risk. A quick look before winter can save a lot.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before you book.

How we price electronic leak detection
Several things affect the price of a survey:
- How tall the building is and how easy the roof is to see
- The type of building, from a house to a block or an office
- Roof area
- How complicated the roof is, with its valleys, chimneys and parapets
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Helping us price your survey
Before you get in touch, it helps to have:
- Whether there is a loft hatch, a shared roof or tricky access
- The property’s address and postcode
- Photos of the roof, taken safely from ground level or a window
- Your timetable, like an exchange date
If you have photos of the roof, send them over. Take them safely from ground level or a window; never climb up to get a better view. To get started, call 07833 053749 or send us an email.
Tips that help
Over many surveys, some simple habits stand out as worth the effort:
- Share any drawings of the roof
- Check new waterproofing before handover
- Don’t keep patching the same spot
- Don’t leave water getting in
Questions about the results are welcome. We can talk you through the findings.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.

The survey, step by step
Every roof is different; as a rough guide, the survey takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. You’re welcome to ask questions while we are there. Around Westhumble, older homes can have small or awkward roof spaces, so let us know about the loft hatch and any ladder. We only go where it is safe.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- A report with photos shows where each breach is.
Before we arrive
- Keep pets in another room
- Make a note of anything you’d like us to look at
