Electronic leak detection around Arnos Grove
About 2.6 miles south-east lies Bruce Castle, a reminder of how long the area around Arnos Grove has been built on. Older homes in the wider area often 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 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. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops.
For an older house near a landmark such as Syro-Malabar Catholic Church of London, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. If you look after a shop, office or commercial unit, for instance near The Mall Wood Green, the flat roofs over shops and commercial units are worth checking before a leak, not after. For a London address like Arnos Grove, it helps to know about controlled parking before the day.

Electronic leak detection in Arnos Grove: what you get
Our ELD testing covers flat roofs in Arnos Grove and the rest of London and the South East. A visit normally 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 survey flat roof membranes, liquid-applied waterproofing and commercial flat roofs, and the problems we are asked to look at most are punctures from foot traffic or tools and repairs that haven’t stopped the leak.
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 Arnos Grove, the flat roof is often a shared part of the building.
After the visit, you get a written report with photos, emailed to you. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

Different roofs, different checks
Bituminous membranes
Bituminous roofs frequently have laps and old repairs that can leak. Testing depends on the roof.
Green and ballasted roofs
Testing before planting or ballast goes on is simpler.
Checking the roof from ground level
Your own check is a good start, but it isn’t a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level.
What you can’t do safely is get up close. Roofs are fragile and slippery. That’s where a survey comes in, using safe viewpoints and a drone where applicable.
How it works
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. All told, expect a length of time set by the size of the roof and how it’s built, which we set out in the quote. London terraces rarely offer a view of the whole roof from one spot, so a visit in Arnos Grove moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, tell us who can let us into the shared parts.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Getting ready for the survey
- Have keys ready for side gates, garages or roof access doors
- Gather any invoices or paperwork from past roof work
- Move anything stored under the loft hatch

Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, ring 07833 053749 or drop us an email.
Advice
What electronic leak detection doesn’t cover
Every survey has limits, and we’d rather be clear about that before you book. Bear these in mind:
- Build-ups without a suitable layer below
- Leaks from plumbing or windows
- The extent of water in the insulation
If in doubt, phone 07833 053749 or send us an email and we’ll point you to the right survey. What our survey covers.
Roofs we survey in Arnos Grove
- Green roofs
- Flat roof membranes
- Commercial flat roofs
- Liquid-applied waterproofing
- Single-ply roofs
- Roof terraces and balconies
Why it’s worth a survey now in Arnos Grove
Water trapped under a membrane can soak insulation and decking. Locating it early helps limit the damage. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. When the stain finally shows, the damage underneath is frequently older than it looks.
To find out what your survey will cost, phone 07833 053749 or email us and let us know about the roof. We’ll confirm the figure before booking.
Why us?
- PI and public liability insurance
- Drones and thermal imaging where it applies

Common questions in Arnos Grove
Is parking a problem for a survey in Arnos Grove?
It rarely stops a survey, but it is worth planning. Let us know what parking is available nearby, and the visit is planned around it.
How do I find out if my home in Arnos Grove is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. 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 you walk on the 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.
What’s the best way to book?
Simply call 07833 053749 or email us. We will ask a few questions, confirm the price and agree a date.
Is it a structural engineer’s report?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but we do not provide calculations or an engineer’s opinion. If one is needed, the report says so.
Is the repair part of the test?
No, our part is finding the breaches. Your roofer uses the report to target the repair.
Is this an asbestos survey?
No. Asbestos surveys and testing are not part of what we do. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings.
Before and after the survey
From years of surveys, a few habits stand out as worth the effort:
- Tell us about the membrane and build-up if you know it
- Note where leaks show inside and when
- Keep foot traffic on flat roofs to a minimum
- Use boards when working on the roof
If anything in the report isn’t clear, ask us. We can talk you through the findings.
Check contractors protect the waterproofing when fitting equipment. Have the roof looked at after other work.
