Why get it checked now?
Repeated call-outs for the same leak add up. A clear record of where the breaches are helps break that cycle. Older cottages and farmhouses around Walkern can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it’s left.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.

Electronic leak detection for homes and businesses in Walkern
Electronic testing locates holes in the waterproofing but not every way water gets in. Leaks from walls, copings, rooflights or pipes need other checks. If the evidence points elsewhere, we will say so. The test shows breaches in the membrane, not water coming through masonry or around frames. Our report keeps that distinction clear. You’ll also know what to check next. If you’ve noticed damage from equipment installers and new roofs to check before paving or planting, a survey will tell you what’s going on, whatever the roof.
Older buildings in small places like Walkern may be listed or in a conservation area, which can shape what a new flat roof may look like. If you’re planning work, check with the council first. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.
We keep jargon out of it: where something needs attention, it says so plainly.

How it works
On the day, we start by asking what you’ve noticed and what you want to find out. After that, we check everything we can see safely, using the ground, windows, the loft and a drone where applicable. The survey usually takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. In a hamlet or village like Walkern, a postcode does not always lead to the right gate, so a few directions are welcome. The visit itself is the same as anywhere else.
- We agree the area to be tested.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Before the survey
- Agree roof access with the managing agent if it is shared
- If it isn’t your property yet, arrange access through the agent
- Unlock side gates and any roof access doors

Different roofs, different checks
EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but punctures and seam failures still happen.
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer, but can still have thin spots or holes. Suitability for ELD depends on the system.
Checking the roof from ground level
Look up at the roof after a storm, from the ground: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Do not go up yourself.
The one thing to avoid is getting up close. Roofs are fragile and slippery. That is where a survey comes in.
FAQs for Walkern
Will you come out to Walkern?
Yes, Walkern is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Is my home in Walkern listed or in a conservation area?
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, and councils can also use Article 4 directions.
Do I have to be there for the survey?
It depends on what we need to see. For inside areas and the roof space, someone has to give us access; we will agree the details when booking.
What happens next?
The report comes by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Does the report include photos?
Yes. We photograph the roof as we go, and they go into the written report alongside our recommendations.
Can you survey a shared roof?
Yes. A shared roof needs access agreed first, with the freeholder or managing agent. Tell us about it when booking and we’ll plan the survey around it.
How is ELD priced?
We quote for each roof individually. Send us details of the roof. Just call 07833 053749 or send us an email for a quote.

What electronic leak detection looks like in Walkern
Aston Bury, about 2.9 miles south, is one of the historic houses in the wider area around Walkern. 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. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit.
The streets around a church such as Parish Church of St Mary the Virgin are often among the oldest in a place, and if your home is one of the older ones nearby, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear. Take a building like Walkern Primary School: a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail. For landlords with property near Stevenage station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

Tips that help
A survey works best with a little help from you, before and after. Some tips:
- Don’t leave water getting in
- Stay off the flat roof unless needed
- Avoid repeated repairs without finding the cause
- Test new membranes before covering them
The report records each breach location with photos. Your roofer uses it to carry out repairs.
Consider testing a new membrane before it’s covered. Finding breaches is simpler at that stage.
