Electronic leak detection for homes and businesses in Kenton
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small electrical current which can only get through the membrane at a breach. It can find holes too small to spot by eye, so your roofer can repair them. The results come in a report with photos. Common reasons to book are damage from equipment installers and repairs that haven’t stopped the leak, on roof terraces and balconies, single-ply roofs and green roofs.
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 Kenton, 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.
The report does not just list problems. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

Common questions in Kenton
Is parking a problem for a survey in Kenton?
Parking in Kenton, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when booking.
Do you cover Kenton?
Yes, Kenton is one of the places we work. Every survey there gets the same written report with photographs.
What is electronic leak detection?
A sound membrane blocks the test current, but a hole lets it through. That lets us find breaches that are too small to see.
Which days do you carry out surveys?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Tell us which days suit you as you book.
Can you survey in bad weather?
It depends on the weather and the survey. High wind or heavy rain can make access unsafe and ground a drone, so we’d move the date with you.
When does the report arrive?
Each package has its own report time. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. If you have a deadline, such as an exchange date, tell us when you book.
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.
Different roofs, different checks
Green and ballasted roofs
Green roofs and ballasted roofs cover the waterproofing. Testing may still be possible but it depends on the layers.
Bituminous membranes
Older felt roofs frequently have seams and patches that can leak. We test where the roof suits it.
What happens if roof problems are left?
Not every leak is in the membrane. Testing shows whether the membrane is breached, so other causes can be checked. Blocked gutters and hoppers on London houses overflow and soak brickwork. A small blockage left for a few winters becomes a damp problem.
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the price for the job before booking.

Landlords, agents and block managers in Kenton
If the property is let, the agent or a tenant can let us in, at a time agreed in advance. We survey seven days a week, which helps when tenants work during the week.
With a portfolio of properties, surveys can be booked for more than one address. To arrange surveys for several addresses, ring 07833 053749 or send us an email with the addresses.
Flat and commercial roofs around Kenton
About 2.2 miles west lies Headstone Manor, a reminder of how long the area around Kenton 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 plenty 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. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For an older house near a landmark such as Church of St Mary, flat-roofed rear additions and dormers added over the years are worth checking. For landlords with property near Kenton station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. If you look after a shop, office or commercial unit, for instance near St. Anns, the flat roofs over shops and commercial units are worth checking before a leak, not after.

Useful tips for Kenton property owners
Some practical points come up on survey after survey. They apply to most roofs:
- Avoid repeated repairs without finding the cause
- Ask contractors to protect the membrane
- Get leaks traced quickly
- Check new waterproofing before handover
Wet insulation may need attention after a leak. That is something to discuss with your roofer and other checks can help judge it.
Don’t leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.

What we cannot see
Without opening up the roof, some things stay hidden, and that sets some limits:
- How wet the insulation is
- Parts of the roof covered by fixed equipment
- Roofs whose membrane or build-up isn’t suitable

- Commercial flat roofs

- Liquid-applied waterproofing
- Roof terraces and balconies
- Flat roof membranes
How it works
We don’t take risks to get a closer look. Everything that can be seen safely is inspected, and anything we can’t see is noted in the report. The survey usually takes more time on a big roof than a small one, with the construction of the roof playing a part too. In Kenton, visits are available on weekdays and at weekends. London parking is often by permit or pay-and-display, so it’s useful to know what’s near you. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- We start by finding out what the roof is made of and where it leaks.
- The roof is assessed to see if electronic testing will work on it.
- The method depends on the membrane and what sits above and below it.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photographs in a report for your roofer.
How to prepare
- Keep pets inside or away from the areas we’re looking at
- For flats, make sure roof access has been agreed
- Clear the way to the loft hatch
