How electronic leak detection works in Westbourne
Our ELD testing covers flat roofs in Westbourne and the rest of London and the South East. A visit typically takes longer on a large roof than a small one, with the construction of the roof playing a part too. Every roof is quoted on its size and build-up. The results come in a written report with photos. If you are worried about stains far from any visible defect and failed seams and laps, a survey will tell you what’s going on, whatever the roof.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Each pipe, upstand and fixing through the covering is a possible weak point. In Westbourne, roof access is agreed with the building manager or owner beforehand. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
After the visit, you get a report with photographs, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

What this survey can’t tell you
Some things cannot be seen without opening up the roof, so a survey has limits:
- Parts of the roof covered by fixed equipment
- Some conductive membranes
- Leaks from plumbing or windows
If in doubt, ring 07833 053749 or send us an email and we will point you to the right survey before you book. The full list of what we check.

Prices for electronic leak detection in Westbourne
The price reflects the time and kit the roof needs. That comes down to:
- The type of building, from a house to a block or an office
- The roof’s overall size
- Extensions, dormers and garages with roofs of their own
- The height of the building and how the roof can be seen safely
To find out what your survey will cost, phone 07833 053749 or email us with the address and some details. The price is agreed before a date is set.
Getting in touch
Before you get in touch, it’s useful to have:
- Pictures from the garden or a window, if you have them
- When you need the report by
- Where the property is, with the postcode
- Where any leaks, stains or damp patches show inside
Most bookings start with a short call: phone 07833 053749 or drop us an email and we will ask a few questions about the roof. You’ll have a price before anything is arranged.
How the survey changes by roof type
Bituminous membranes
Bitumen roofs can often be tested electronically though the layers below matter.
Single-ply membranes
ELD often works on single-ply membranes but it depends on the product and layers.
What happens on the day
Every roof is different, but as a rough guide the survey takes a time that depends on the size of the roof and how it’s built, which we set out in the quote. If you have questions on the day, just ask. Surveys in Westbourne can be booked for any day of the week. London parking is often by permit or pay-and-display, so it helps to know what’s near you, and to clear a path to the loft hatch. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- You let us know about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
How to prepare
- Keep pets inside or away from the areas we’re looking at
- Make a note of anything you’d like us to look at
- Let us know about parking near the property

Checking the roof from ground level
During heavy rain, look at the gutters from the ground or a window. Overflowing water can point to a blockage or a sagging run.
Your own check is a good start, but it is not a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
Why act early in Westbourne
Some flat roof leaks come from walls or details. Testing shows whether the membrane is breached so attention can go to the right place. Any roof job in Westbourne means planning around parking, neighbours and access. Knowing what’s needed early gives you time to plan it calmly, rather than in a rush after a leak.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before booking.
Why book with us
- Photos and a written report every time
- Covered by professional indemnity and public liability insurance
- Weekday and weekend surveys
- 5,000+ surveys completed
Electronic leak detection around Westbourne
Historic houses such as Kensington Palace, about 0.8 miles south-east, show how far back building in the area around Westbourne goes. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material. Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. If your home in Westbourne is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Next to the main roofs there is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit.
Landlords with a home close to London Paddington station may find that the flat roof over a let home is worth a look before it becomes a tenant complaint. For hotels and guest houses around Westbourne, a roof problem found early is far less disruptive than one found by a guest, so it is worth knowing the roof’s condition. If you run a business near Kensington Arcade, a flat roof over a business is out of sight and out of mind until it leaks.

Westbourne questions
Can parking be tricky for a visit in Westbourne?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Is my home in Westbourne listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
What do I do with the report?
We email you the written report with photographs and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Does the weather affect the survey?
It can, depending on the survey. Drones can’t fly safely in strong wind or heavy rain, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. We’ll rearrange with you if the weather isn’t right.
Can every flat roof be tested?
Not every roof is suitable. Certain membranes are conductive, and some build-ups lack a suitable layer below. If your roof won’t work, we will say so before testing.
Which days do you carry out surveys?
Surveys run seven days a week. To find a day that suits you, ring 07833 053749 or email us.
How quickly is the report sent?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. Each one is emailed, ready to forward.
