About our electronic leak detection in Neasden
Green roofs, ballasted roofs and roofs under paving are harder to test. 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, as they show what lies beneath the surface. We’ll tell you if the roof can’t be tested. Typical surveys look at damp inside with no sign on the roof and breaches around outlets and penetrations, on green roofs, single-ply roofs and flat roof membranes.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a block or conversion in Neasden, the flat roof is often a shared part of the building.
Most points in the report come with a picture, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

Electronic leak detection in Neasden: local notes
There are several hotels within about a mile and a half of Neasden, and like offices and blocks, hotels often sit under flat roofs. If you look after one, a leak through a flat roof can put a room out of use. About 2.9 miles east lies Fenton House, a reminder of how long the area around Neasden has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area.
If you run a business near London Designer Outlet, a flat roof over a business is out of sight and out of mind until it leaks. If you look after a building such as Northview Junior and Infant School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

The survey, step by step
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. A typical visit takes a time that depends on the roof’s area and construction, which we’ll explain when we quote. London terraces rarely offer a view of the whole roof from one spot, so in Neasden we work round the house, using the street, the windows, the loft and any safe vantage point behind it. Shared stairs or a basement flat? Tell us who holds the keys.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Preparing for the visit
- Find any records of previous roof work
- If it is not your property yet, arrange access through the agent
- Mention any parking restrictions on your street

Common questions in Neasden
How do I find out if my home in Neasden is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. 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.
Will parking be an issue for a roof survey in Neasden?
Typically it is manageable with a little notice. Let us know the parking rules on your street and we will work around them.
How quickly is the report sent?
It depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. Reports are sent by email.
How is ELD priced?
Electronic leak detection is quoted for your roof, because the method depends on the roof. Size, build-up and access all affect the price. To get a quote, call 07833 053749 or email us.
Will you fly a drone over my roof?
Where it helps and the rules allow, yes. 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.
Do you survey roofs on blocks of flats?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we are allowed to reach.
Can you survey at the weekend?
We carry out surveys seven days a week. To find a day that suits you, phone 07833 053749 or send us an email.
Prices for electronic leak detection in Neasden
What a survey costs depends on the time and equipment it needs. That comes down to:
- How many separate roofs there are, like extensions, dormers and garages
- Chimneys, valleys, parapets and other details
- The height of the building and how the roof can be seen safely
- Any need for thermal images or a drone flight
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You will know the figure before booking.
What we need to know
These details help when you contact us:
- The address and postcode of the property
- Pictures of the roof from a safe spot, if you have them
- The kind of building and roof involved
- Access details, such as a loft hatch or a shared roof
For a price for electronic leak detection in Neasden, phone 07833 053749 or email us. A few details about the property and the roof help us price the survey accurately.

When to book a survey in Neasden
On a flat roof, water spreads under the waterproofing. The leak may show some distance from where water gets in, so tracing it by eye is difficult.
A survey makes sense if you’ve noticed:
- Leaks that return after repairs
- Punctures from foot traffic or tools
- Waterproofing to test before it is covered
- Damp inside with no sign on the roof
Take an older house close to St Catherine's Church Neasden with St Paul: later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear.
Choosing a roof surveyor
- Whether the loft is part of the inspection
- Will the report include photos?
- Is VAT included in the price?
- What follow-up you get after the report
Tips that help
These tips come from what we see on roofs every week:
- Don’t let outlets block
- Have roof specifications to hand
- Limit access to the roof
- Act on new leaks promptly
File the report with your roof paperwork. It’s a dated record of the membrane’s condition.
Act on leaks quickly. Water under a membrane can spread.
For landlords and managing agents
With a portfolio of properties, surveys can be booked for more than one address. To arrange surveys for several addresses, phone 07833 053749 or send us an email with the addresses.
We also survey roofs for businesses and commercial landlords, including offices, shops and units. Larger roofs take longer, and they’re priced for the size.
