What happens on the day
On the day, we start by asking what you’ve noticed and what you’d like to know. We then inspect everything that can safely be seen, from the ground, from windows, in the loft space and by drone where applicable. The survey usually takes a time that depends on the membrane area and the build-up, which we set out in the quote. For a visit in Edgware, parking and access are the things to plan: let us know about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at what can be seen safely from the ground, windows, the loft and, where it is safe, the roof itself.
- We agree the area to be tested.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Preparing for the visit
- Clear the way to the loft hatch
- Buyers: confirm access with the estate agent or seller
- Have any questions written down, so nothing gets missed
Getting a price
Every survey is priced before it is booked, so you know the cost up front. Electronic leak detection is quoted for your roof, because the method depends on the roof. To book, phone 07833 053749 or send us an email.

Electronic leak detection for homes and businesses in Edgware
We carry out electronic leak detection on flat roofs in Edgware and across London and South East England. Testing typically takes a length of time set by the size of the roof and how it’s built, which we’ll explain when we quote. Every roof is quoted on its size and build-up. The results come in a written report with photos. We’re often asked to look into a flat roof leak that can’t be traced and holes left by work on the roof, on liquid-applied waterproofing, green roofs and flat roof membranes.
Commercial and residential blocks across London frequently have big flat roofs with plant, rooflights and access walkways. Every penetration and upstand is a place where a membrane can fail. For a building in Edgware, 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.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

Electronic leak detection around Edgware
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. If your home in Edgware is one of them, bay roofs, hips and later dormers each have their own details. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. About 3.9 miles south-west lies Headstone Manor, a reminder of how long the area around Edgware has been built on. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area.
If you own a rental within reach of Mill Hill Broadway station, the flat roof over a let home is worth a look before it becomes a tenant complaint. For a London address like Edgware, it helps to know about controlled parking before the day. For site and facilities teams at buildings like Beit Shvidler Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

DIY checks: what’s safe
A DIY look is useful, but it is not a survey. From ground level, valleys, flashings and the backs of chimneys are frequently out of sight, and those are details a survey looks at closely.
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
How we price electronic leak detection
Prices vary from roof to roof, for these reasons:
- Height and safe access
- If the survey needs thermal imaging or a drone
- The size of the roof
- Extensions, dormers and garages with roofs of their own
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before booking.
Getting in touch
The more you tell us, the easier it is to price the survey. When you contact us, it’s useful to mention:
- What made you get in touch
- Anything about access we should know
- Where water is showing inside, if it is
- Your timetable, like an exchange date
A quick phone call is typically the easiest start: phone 07833 053749 or send us an email, and we’ll ask about the building and what you need. You’ll have a price before anything is arranged.
What happens if roof problems are left?
Not every leak is in the membrane. ELD helps rule the membrane in or out so attention can go to the right place. In a London terrace or conversion, a roof defect rarely stays your problem alone: 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, call 07833 053749 or drop us an email and let us know about the roof. The price is agreed before a date is set.

Edgware questions
Is Edgware in the area you cover?
Yes, Edgware is within the area we cover. We work right across London and the South East. Just ring 07833 053749 or send us an email and tell us about the property.
Is my home in Edgware 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. The answer matters most when a change of material is on the cards.
What do I do with the report?
You will receive the report by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Is this a RICS survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof and can sit alongside a RICS survey.
Can you find leaks on a covered flat roof?
In some cases. It depends on the build-up and the layers above the membrane, and some may need lifting. We’ll discuss it before we quote.
Do you use drones?
Yes, where it’s applicable. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and every flight depends on the airspace and the weather.
Which days do you carry out surveys?
We survey on any day from Monday to Sunday, during the day. Just say which days work for you.
