Electronic leak detection for homes and businesses in Berden
Water can travel under a flat roof membrane before it shows inside. That makes leaks hard to trace by eye. Electronic leak detection tests the membrane itself and locates the breach. It’s testing only, and the repair is for your roofer. On suitable roofs, it replaces guesswork with a located breach. We then send you the results in a written report. We survey commercial flat roofs, liquid-applied waterproofing and single-ply roofs, and the problems we are asked to look at most are leaks at pipes, outlets or fixings and leaks that return after repairs.
In a small place like Berden, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, normally show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
Every survey ends with a written report, with photographs, sent by email. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

What we look for on each type of roof
EPDM rubber roofs
ELD on EPDM depends on the product and the layers. We look at this first.
Bituminous membranes
Bituminous felt and modified bitumen membranes are common. Whether ELD suits them depends on the build-up.
Should I look at the roof myself first?
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
For landlords and managing agents
Freeholders and residents’ companies use a roof report to plan and budget.
Landlords, agents and building managers in Berden and across Hertfordshire can book any of our surveys. To discuss a property or a block, phone 07833 053749 or use the contact form.
Flat and commercial roofs around Berden
Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material, so the council is the place to ask.
For an older house near a landmark like St. Nicholas Church, the flat roofs on later extensions tend to wear out long before the main roof. Landlords with a home close to Newport (Essex) station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.

FAQs for Berden
Will you come out to Berden?
Yes, smaller places are covered as well as towns. Our area covers London and the South East. Just mention lanes, gates or anything else about the route as you book.
Is Berden in the area you cover?
Yes, Berden is one of the places we work. The survey and report are the same in Berden as anywhere else, and visits run on weekdays and weekends.
How long will testing take?
It depends on the size of the roof and its build-up. We will give you an idea when we quote.
I live in a flat. Can you survey the roof?
Yes. A shared roof needs access agreed first, with whoever owns or manages the building. Tell us about it when you book and we’ll explain what’s needed.
Can you test a green or ballasted roof?
On some roofs, yes. Covered roofs limit the methods we can use so we look at the roof first.
Are you insured?
Professional indemnity and public liability insurance cover our surveys. If you need details for a managing agent or a building owner, just ask.
Is this a RICS survey?
No. It’s a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof, so it sits alongside a building survey rather than replacing it.

What happens on the day
You don’t need to do much on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we’ll take it from there. The survey itself takes a time that depends on the membrane area and the build-up, and we’ll give you a guide when quoting. In a hamlet or village like Berden, a postcode does not always lead to the right gate, so a few directions are welcome. After that, the survey runs as it would anywhere.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Before we arrive
- Make sure we can get to the back of the property
- Agree roof access with the managing agent if it is shared

Related advice
Why get it checked now?
Repeated call-outs for the same leak add up. A report showing the breach points gives your roofer a clear target. Where a roof is exposed, as many are in small places like Berden, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.
