Electronic leak detection in Southgate, Greater London
Find out the condition of the flat roof membrane at your property in Southgate. Visits run on weekdays and weekends, in the daytime.
- Leaks showing away from the breach
- Leaks at pipes, outlets or fixings
- Failed seams and laps
What happens on the day
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes a length of time set by the roof’s area and construction, and we’ll give you a guide when quoting. If you have questions on the day, just ask. In a London area like Southgate, the main things to sort out are parking and access: let us know about parking, the floor the property is on, any shared entrance and loft access. We then look at everything that’s safely in view from ground level, windows, the loft and, where it is safe, the roof itself.
- First, you let us know about the roof build-up and where water is showing.
- We check that the membrane and build-up suit electronic leak detection.
- We pick the low-voltage or high-voltage method that suits the roof.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
How to prepare
- Clear the way to the loft hatch
- Jot down any questions you want answered
- Make sure pets are kept safely away

Electronic leak detection in Southgate: what you get
Some flat roofs can’t be tested electronically. Some membranes conduct electricity themselves and some roofs don’t have a suitable layer beneath the membrane. We will say if ELD will not work on your roof before any testing. Telling us what you know about the roof’s membrane and layers helps, such as drawings or specifications. It avoids arranging a test that can’t give results. We survey roof terraces and balconies, liquid-applied waterproofing and green roofs, and the problems we’re asked to look at most are water coming in under a flat roof and holes left by work on the roof.
Offices, shops and blocks of flats across London often have large flat roofs with plant, rooflights and walkways. Every penetration and upstand is a place where a membrane can fail. In Southgate, roof access is agreed with the building manager or owner beforehand. Plant bases, rooflights and cable entries are all places where water can get in.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

Why it’s worth a survey now in Southgate
Leaks left running can wet the insulation and deck. Finding the breach sooner limits that. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. 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 you book.
Why choose Independent Roof Survey in Southgate
- Drones and thermal imaging where it applies
- A written report with photographs
- Independent findings on the roof’s condition
- Covered by professional indemnity and public liability insurance
DIY checks: what’s safe
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. Don’t go up yourself.
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
When you need someone else
It helps to know what a survey won’t do before booking:
- Moisture spread under the membrane
- Roofs whose membrane or build-up isn’t suitable
- Repairing the breaches (that is for your roofer)
If in doubt, ring 07833 053749 or send us an email and we’ll recommend the right survey before you book. What our survey covers.
Roof types and parts we check
- Liquid-applied waterproofing
- Roof terraces and balconies
- Green roofs
- Commercial flat roofs
- Flat roof membranes
- Single-ply roofs
What affects the price in Southgate
We confirm the price for your survey before you book. This is what makes a difference:
- The type of building, from a house to a block or an office
- The roof’s overall size
- If the survey needs thermal imaging or a drone
- How many separate roofs there are, such as extensions, dormers and garages
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
What to tell us when you get in touch
There is no need for technical words. Just tell us:
- Where any leaks, stains or damp patches show inside
- Dates you’re working to, such as exchange
- The style of property, from a terrace to a block
- Photos of the roof, taken safely from the ground or a window
Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, ring 07833 053749 or use the contact form with the address and the days you’d prefer.

What else we do in Southgate
Flat and commercial roofs around Southgate
Bruce Castle, about 3.2 miles south-east, is one of the historic houses in the wider area around Southgate. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material. Outer London has plenty 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. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
For landlords with property near New Southgate station, the flat roof over a let home is worth a look before it becomes a tenant complaint. Take a building like Ashmole Primary School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. Controlled parking zones are common in London, so mention any permit rules for Southgate, along with any off-street space.

Common questions in Southgate
How do I find out if my home in Southgate is listed?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
Is Southgate in the area you cover?
Yes, Southgate is within the area we cover. We work right across London and the South East. Just call 07833 053749 or email us and let us know about the property.
Does ELD include fixing the breach?
No. ELD is testing only. You get the breach locations with photos so your roofer can fix them.
How do I arrange electronic leak detection in Southgate?
It is easiest to call 07833 053749 or send us an email. Tell us the address and a little about the roof, and we’ll suggest the right survey. Surveys run on weekdays, Saturdays and Sundays.
Do you survey roofs on blocks of flats?
Yes. Shared roofs just need a little more planning, with the building owner or managing agent. Tell us about it when booking and we will explain what’s needed.
Does ELD work under paving or planting?
Sometimes. It depends on the build-up and the layers above the membrane and parts may need to be lifted. We will discuss it before we quote.
Do you climb onto every roof?
Not always. Some roofs are too steep or fragile to walk on safely. Safe viewpoints, the loft and a drone where it applies let us see the rest, and the report records anything we couldn’t see.
