About our electronic leak detection in Bush Hill
Electronic leak detection works on many flat roof membranes, 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. Tell us about your roof to find out more. If you’re worried about leaks through a flat roof with no obvious cause and failed seams and laps, we can find out what’s behind it.
Offices, shops and blocks of flats across London often have large flat roofs with plant, rooflights and walkways. Each pipe, upstand and fixing through the covering is a possible weak point. For a building in Bush Hill, access is agreed with whoever manages the roof before the visit. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
What you get is a clear record of the flat roof membrane on the day we saw it. That makes it useful now and a handy reference later.

How the survey changes by roof type
Bituminous membranes
Older felt roofs often have seams and patches that can leak. We test where the roof suits it.
Green and ballasted roofs
Testing before planting or ballast goes on is simpler.
FAQs for Bush Hill
Is parking a problem for a survey in Bush Hill?
Sometimes, yes. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well.
Do you carry out roof surveys in Bush Hill?
Yes. We work right across London and South East England, and Bush Hill is part of that. You can phone 07833 053749 or drop us an email with the address and some details, and we’ll talk through which survey suits.
How long does electronic leak detection take?
It depends on the size of the roof and its build-up. We’ll give you an idea when we quote.
Will you repair the leak?
No. ELD is testing only. The report shows where each breach is so your roofer can fix them.
What do I do with the report?
We email you the written report with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
What does electronic leak detection do?
A sound membrane blocks the test current, so wherever there is a hole, it passes through. That lets us find breaches that are too small to see.
Does the weather affect the survey?
Some surveys depend on the weather more than others. Drones cannot fly safely in strong wind or heavy rain, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. If the conditions are not right, we will talk to you about another date.
What affects the cost of electronic leak detection
All our prices include VAT. What changes the price is:
- The number of roofs, including extensions and garages
- The use of thermal imaging or a drone
- Commercial roofs and larger buildings
- The roof’s overall size
The cost of a survey depends on the roof: 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
When you call or email, these details help:
- Whether there is a loft hatch, a shared roof or tricky access
- What’s prompted the survey
- The type of building and roof, such as pitched or flat
- Any stains, drips or damp patches you’ve seen indoors
You can call us seven days a week, including Saturdays and Sundays. For a price or to book, phone 07833 053749 or send us an email.
How it works
After the inspection, everything we found is written up as a photo-illustrated written report, emailed to you. On timing, it typically takes more time on a big roof than a small one, with the construction of the roof playing a part too. Many London properties are flats or terraces with no side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. If the building has a managing agent or access rules, let us know as you book.
- First, you tell us about the roof build-up and where water is showing.
- We confirm whether the roof is suitable for electronic testing.
- The method depends on the membrane and what sits above and below it.
- The roof is tested and any breaches are located.
- The breaches are recorded with photos in a report for your roofer.
Before the survey
- If you are buying, check with the agent that we can get in
- Let us know about parking near the property
- Make sure the loft hatch can be reached

Why get it checked now?
Opening up a roof to hunt for a leak is disruptive. ELD aims to locate the breach first, so the repair can be targeted. In Bush Hill, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: failed flashings and blocked valley gutters can send water into more than one home. Finding it early keeps the work smaller.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before you book.
Why us?
- Weekday and weekend surveys
- A sub-250g drone, flown with a CAA Flyer ID and Operator ID
- Over 5,000 surveys carried out
- Two decades and more of roof surveys

Checking the roof from ground level
It is useful to keep a record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry.
Look up at the roof after a storm, from ground level: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Do not go up yourself.
Flat and commercial roofs around Bush Hill
Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. Historic houses such as Forty Hall, about 2.1 miles north, show how far back building in the area around Bush Hill goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
If you look after a shop, office or commercial unit, for example near Edmonton Green Shopping Centre, flat roofs over shops and units are easy to forget until water comes through a ceiling. For a London address like Bush Hill, it is useful to know about controlled parking before the day. For an older house near a landmark like Grange Park Methodist Church, the joins between later flat roofs and the old walls are where problems typically start.
