About our electronic leak detection in Wallington
Electronic leak detection works on many flat roof membranes over offices, units, blocks of flats and homes. It helps trace a leak you already have or check a new membrane before handover. We quote for each roof based on its size and build-up. We can test on weekdays and at weekends, depending on the weather. Just ask about your roof. If you’re worried about breaches hidden under paving or planting and leaking laps in the waterproofing, we can find out what’s behind it, whatever the roof.
Some older homes in villages like Wallington are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
Nothing in the report is left vague: where something needs attention, it says so plainly.

Flat roofs in Wallington
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Historic houses such as Hinxworth Place, about 4.9 miles north-west, show how far back building in the area around Wallington goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.
For landlords with property near Ashwell & Morden station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. If yours is one of the older homes in the streets near Church of St Mary, flat-roofed rear additions and dormers added over the years are worth checking.
Wallington is about 5 miles east of Letchworth, in Hertfordshire. Whether the building in Wallington is a house, a flat or a commercial unit, the roof can be surveyed. Our area takes in places right across Hertfordshire. There is also a page for Milton Keynes.

A roof problem in a let property affects your tenants as well as the building. A survey helps you spot issues early and plan the work.

What you can safely check yourself
Your own check is a good start, but it is not a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight.
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Useful tips for Wallington property owners
These tips come from what we see on roofs every week:
- Record dates and spots where water appears
- Stay off the flat roof unless needed
- Find the breach before more patching
- Keep outlets clear of debris
Once repairs are made, the roof can be tested again if you want to check them, where the roof still suits the method.
Clear flat roof outlets regularly. Water that sits on the roof finds breaches faster.
Questions from Wallington
Is Wallington within the area you cover?
Yes, we do. We work right across London and South East England, from towns to the smallest villages. The journey is planned ahead, so it’s useful to know about access.
Is Wallington in the area you cover?
We do. The survey and report are the same in Wallington as anywhere else, and visits run on weekdays and weekends.
Can you tell me if my roof has asbestos?
No. We do not carry out asbestos surveys or testing. We flag materials that could contain asbestos, like cement sheets or soffits on pre-2000 buildings and suggest a specialist asbestos surveyor checks them before any work.
What’s the price of ELD?
Each roof is quoted on its size and build-up. Send us details of the roof. Just ring 07833 053749 or email us for a quote.
I live in a flat. Can you survey the roof?
Yes. Shared roofs just need a little more planning, with the building owner or managing agent. Mention it when you get in touch and we’ll explain what’s needed.
Are you structural engineers?
No. We’re experienced roof surveyors, and visible signs like sagging are noted, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
How long will testing take?
The roof’s size and build-up decide how long it takes. You’ll know roughly how long before we start.
How the survey changes by roof type
Liquid-applied waterproofing
Testing a liquid-applied roof depends on what’s beneath the coating.
Single-ply membranes
Single-ply can be punctured by tools or fixings. ELD can locate them.
How the survey works
Every roof is different; as a rough guide, the survey takes more time on a big roof than a small one, with the construction of the roof playing a part too. If you have questions on the day, just ask. Older roofs in small places like Wallington can have low, tight loft spaces, so it helps to know whether there’s a loft hatch and how easy it is to reach. We only go where it’s safe.
- First, you let us know about the roof build-up and where water is showing.
- We confirm whether the roof is suitable for electronic testing.
- 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.
Before we arrive
- Have keys ready for side gates, garages or roof access doors
- Show us where any leaks or stains appear
- If you are buying, let the agent know when we’re coming

What affects the cost of electronic leak detection
Prices vary from roof to roof, and it comes down to:
- The shape of the roof and its details
- If the survey needs thermal imaging or a drone
- How many separate roofs there are, like extensions, dormers and garages
- Building height and the viewpoints available
Every price we give includes 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.
