How electronic leak detection works in Hillingdon
Electronic leak detection works on many flat roof membranes over offices, units, blocks of flats and homes. It can be used to trace an existing leak or to test a new membrane before it’s covered. Each roof is quoted on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays, depending on the weather. Just ask about your roof. We survey liquid-applied waterproofing, flat roof membranes and commercial flat roofs, and the problems we are asked to look at most are holes left by work on the roof and leaking laps in the waterproofing.
Offices, shops and blocks of flats across London frequently have large flat roofs with plant, rooflights and walkways. Each pipe, upstand and fixing through the covering is a possible weak point. In Hillingdon, 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.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. You’ll know exactly what was inspected and what wasn’t, and what we’d suggest next.

DIY checks: what’s safe
During heavy rain, look at the gutters from the ground or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
Your own check is a good start, but it isn’t 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.
The survey, step by step
We work from the outside in: outside views come first, then the roof space if there is safe access. All told, expect a time that depends on the membrane area and the build-up, and we’ll give you a guide when quoting. In a London conversion, the way into the roof space is often from a communal landing or the top flat. Where that is the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Hillingdon runs like any other.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Before we arrive
- Show us where any leaks or stains appear
- Have keys ready for side gates, garages or roof access doors
- Keep pets inside or away from the areas we are looking at
Arrange a survey
If you’re buying, it’s useful to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply call 07833 053749 or email us whenever suits you.

FAQs for Hillingdon
Can parking be tricky for a visit in Hillingdon?
It can be, so it is useful to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Do you cover Hillingdon?
Yes, Hillingdon is within the area we cover. We survey roofs across London and the South East. You can phone 07833 053749 or email us with the address and a few details, and we will talk through which survey suits.
How fast do I get the report?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email.
Can you survey a shared roof?
Yes, as long as access is agreed. The roof of a block or converted house is often shared, so we need permission from whoever owns or manages the building. We inspect only the parts we’re allowed to reach.
How many surveys have you done?
We have been surveying roofs for over 20 years and have completed over 5,000 surveys across London and South East England.
Do you use low-voltage or high-voltage testing?
The roof decides the method. You’ll know which method we plan to use before we start.

Electronic leak detection around Hillingdon
Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, frequently with hipped roofs in clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Next to the main roofs there is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. About 1.8 miles north lies Ickenham Hall, a reminder of how long the area around Hillingdon 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.
For a London address like Hillingdon, it helps to know about controlled parking before the day, along with any off-street space. If you live in an older home near Church of St John, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. For landlords with property near West Drayton station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

What happens if roof problems are left?
Water trapped under a membrane can soak insulation and decking. Finding the breach sooner limits that. In Hillingdon, 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.
