Electronic leak detection in Cricklewood
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small electrical current that passes through the membrane only where there is a breach. That lets us locate holes that are too small to see, so your roofer can repair them. You get a written report with photos of each breach found. We survey commercial flat roofs, roof terraces and balconies and flat roof membranes, and people most often book us about gaps at membrane joints and leaks through a covered membrane.
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 Cricklewood, the flat roof is frequently a shared part of the building.
We write the report in plain English, so you don’t need to be a roofer to follow it. Each point is backed by a photo where possible, and recommendations are put with the most urgent first where relevant.

Your questions about electronic leak detection in Cricklewood
Do you carry out roof surveys in Cricklewood?
Yes, Cricklewood is within the area we cover. We work right across London and the South East. Just phone 07833 053749 or drop us an email and let us know about the property, and we’ll talk through which survey suits.
How do I find out if my home in Cricklewood 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.
How do I book a survey in Cricklewood?
Simply phone 07833 053749 or email us with the address. After a few questions, we confirm the price and fix a day, weekday or weekend.
Can you inspect my roof with a drone?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
How many surveys have you done?
We have more than 20 years’ experience and have completed over 5,000 surveys across London and South East England.
Can you survey at the weekend?
We survey seven days a week: weekdays, Saturdays and Sundays. Let us know which days suit you as you book.
How quickly is the report sent?
Report times are set by the package. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. Mention any deadline as you book.
Different roofs, different checks
Green and ballasted roofs
Parts of the covering may have to come up. We discuss this before quoting.
Single-ply membranes
Many offices and units have single-ply roofs. Laps and fixings are where holes frequently appear.
What we’re asked to look at in Cricklewood
Repeated leaks after repairs suggest the real breach hasn’t been found. Electronic testing helps pinpoint it.
These are some of the problems a survey can pick up:
- Breaches around outlets and penetrations
- Leaks through a covered membrane
- Water coming in under a flat roof
- Stains far from any visible defect
Cricklewood is in London, so parking needs planning: a visitor permit or a nearby bay makes the day easier.
Before you book anyone
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Are they insured for the work?
- How long the report takes to arrive
- Whether you can ask questions once you have the report
Flat roofs in Cricklewood
Outer London has a good many 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. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. About 1.7 miles east lies Fenton House, a reminder of how long the area around Cricklewood has been built on. 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.
If your home is one of the older ones in the streets near St Gabriel's Church, flat-roofed rear additions and dormers added over the years are worth checking. For landlords with property near Cricklewood station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Cricklewood is about 1 mile north-west of Kilburn, in Greater London. In Cricklewood, as across Greater London, every roof gets the same careful survey. Cricklewood is one of the places in Greater London where we work for electronic leak detection. We also survey roofs in London.

What we cannot see
No survey can tell you everything, and we’d rather be clear about that before booking. Bear these in mind:
- Areas we cannot reach or that cannot be tested
- The extent of water in the insulation
- Leaks from plumbing or windows

Roof problems in a rented home affect tenants as well as the building. A survey shows what needs attention, so you can plan the work with less disruption.
The survey, step by step
It is useful to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. It helps us focus on what matters most to you. The visit typically takes more time on a big roof than a small one, with the construction of the roof playing a part too. Surveys in Cricklewood can be booked for any day of the week. It helps if you can point us to a visitor permit or a nearby bay. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
