About our electronic leak detection in West Heath
Roofs covered with paving, ballast or planting need more thought. What sits on the membrane can affect which method will work and parts may need to be lifted. We talk this through before we quote. Any details of the build-up help because they show what’s under the surface. We will tell you if the roof cannot be tested. If you’ve noticed new roofs to check before paving or planting and failed seams and laps, we can find out what’s behind it, on single-ply roofs, green roofs and roof terraces and balconies alike.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, each with its own weak points. Which one is on a roof in West Heath shapes how it’s checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
The report is written in plain words, so it makes sense without any roofing background. Each point is backed by a photograph where possible.

Why it is worth a survey now in West Heath
Patching where you think the leak is often misses it. ELD shows the actual breach points. In West Heath, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Finding it early keeps the work smaller.
To find out what your survey will cost, phone 07833 053749 or send us an email and tell us about the roof. The price is agreed before a date is set.

What we do, 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, using the ground, windows, the loft and a drone where it applies. Most surveys take as long as needed for the size of the roof and how it’s built, and we’ll give you a guide when quoting. From the street, a London terrace normally shows only its front slope or parapet, so a visit in West Heath moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, tell us who can let us into the shared parts.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We confirm whether the roof is suitable for electronic testing.
- We pick the low-voltage or high-voltage method that suits the roof.
- Testing runs across the roof to locate breaches in the membrane.
- The breaches are recorded with photos in a report for your roofer.
Before we arrive
- If the roof is shared, arrange access with whoever manages the building
- Clear the way to the loft hatch
- Make sure we can get to the back of the property
How to book
Booking is simple: just phone 07833 053749 or email us and give us some details about the property and we will point you to the right survey. We confirm the price before anything is booked.

Electronic leak detection around West Heath
About 1.5 miles south lies Danson House, a reminder of how long the area around West Heath has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. If your home in West Heath is one of them, bay roofs, hips and later dormers each have their own details. Next to the main roofs there’s normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.
The streets around a church such as St Andrew's are often among the oldest in a place, and if yours is one of the older homes nearby, the joins between later flat roofs and the old walls are where problems normally start. For site and facilities teams at buildings such as Hillsgrove Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
West Heath is about 1 mile north-east of Welling, in Greater London. West Heath is part of the area we cover across London and South East England. West Heath is one of the places in Greater London we cover for electronic leak detection. We also survey roofs in London.

West Heath: your questions answered
Is West Heath in the area you cover?
We do. The survey and report are the same in West Heath as anywhere else, and visits run on weekdays and weekends.
Can parking be tricky for a visit in West Heath?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Is this a RICS survey?
No. Our survey looks at the roof, not the whole building. If you need a full building survey, you’ll need a RICS survey as well.
How do I arrange electronic leak detection in West Heath?
Simply ring 07833 053749 or use the contact form. After a few questions, we confirm the price and fix a day.
How long will testing take?
It normally takes as long as needed for the roof’s area and construction, which we set out in the quote.
What insurance do you have?
Every survey is covered by professional indemnity and public liability insurance.
Do you use drones?
Yes, where it is applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.
What we are asked to look at in West Heath
Work on the roof can damage a membrane. Engineers fitting equipment, solar panels or aerials may leave damage behind.
Problems we come across often include:
- Leaks that return after repairs
- Punctures from foot traffic or tools
- Leaks at pipes, outlets or fixings
- Waterproofing to test before it’s covered
If you look after a shop, office or commercial unit, for example near Broadway Shopping Centre, outlets and upstands on commercial flat roofs are the places to check before trouble starts.
Choosing a roof surveyor
- Whether the price includes VAT
- Whether they hold professional indemnity and public liability insurance
- What’s outside the scope of the survey
- When you will get the report
How the survey changes by roof type
Green and ballasted roofs
Parts of the covering may have to come up. We discuss this before quoting.
Single-ply membranes
Single-ply can be punctured by tools or fixings. ELD can locate them.
Tips that help
Over many surveys, some simple habits stand out as worth the effort:
- Consider ELD before paving or planting goes on
- Do not leave water getting in
- Use boards when working on the roof
- Avoid repeated repairs without finding the cause
If we think the leak is not coming through the membrane, the report says so, with a suggestion of what to check next.
Keep outlets and gutters on flat roofs clear. Water that sits on the roof finds breaches faster.
