Electronic leak detection in Kevington: what you get
You get a report showing the location of each breach, with photographs. Your roofer can then repair those points rather than guessing. Repair costs aren’t part of the report; that is for your roofer to price. A retest after repairs can check the work if the build-up allows. You get a report with photos. We survey liquid-applied waterproofing, roof terraces and balconies and flat roof membranes, and common reasons people get in touch are leaking laps in the waterproofing and waterproofing to test before it’s covered.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a converted house in Kevington, the roof above may belong to the building rather than one flat.
After the visit, you get a photo-illustrated written report, emailed to you. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

Surveys for landlords and agents in Kevington
Shared roofs need a little more planning: we need access agreed with whoever owns or manages the building. Tell us about it as you book and we will plan the visit with that in mind.
Businesses and commercial landlords can book us too. Larger roofs take longer, so they’re priced to suit.
What we do, step by step
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes a time that depends on the size of the roof and how it’s built, which we set out in the quote. You are welcome to ask questions while we are there. From the street, a London terrace normally shows only its front slope or parapet, so a visit in Kevington moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, let us know who can let us into the shared parts.
- First, you tell us 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.
- The breaches are recorded with photographs in a report for your roofer.
How to prepare
- Dig out any old roof reports or invoices
- Check the loft hatch can be reached
- Keep pets out of the way during the survey

Your questions about electronic leak detection in Kevington
Is Kevington in the area you cover?
We do. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Does a conservation area affect roof work in Kevington?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
Are you structural engineers?
No. We point out what can be seen, like sagging or deflection, but we are not structural engineers and don’t carry out calculations. If we think you need an engineer, the report says so.
Can you survey a shared roof?
Yes. A shared roof needs access agreed first. Let us know about it when booking and we will explain what’s needed.
How do I arrange electronic leak detection in Kevington?
Just call 07833 053749 or drop us an email with the address. After a few questions, we confirm the price and fix a day, weekday or weekend.
How is ELD priced?

How long does electronic leak detection take?
The roof’s size and build-up decide how long it takes. You will know roughly how long before we start.
Flat and commercial roofs around Kevington
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. 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 a good many flat ones, over rear extensions, dormers, garages and shops. Lullingstone Castle, about 3.2 miles south-east, is one of the historic houses in the wider area around Kevington. 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 the council can say whether a home is in a conservation area.
Parking in Kevington, as in most of London, takes a little planning: let us know about parking bays, permits or a driveway when you book. If you look after a building like Manor Oak Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. For an older house near a landmark such as Unity Church, the flat roofs on later extensions tend to wear out long before the main roof.

What happens if roof problems are left?
Opening up a roof to hunt for a leak is disruptive. Electronic testing finds the hole first so your roofer knows where to work. 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.
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the price for your survey before booking.
