About our electronic leak detection in Hudnall
Not every flat roof suits electronic testing. Certain membranes conduct electricity and some roofs do not have a suitable layer beneath the membrane. If your roof is not suitable, we will tell you before any testing. Any details you have about the membrane and build-up help us decide, including drawings, specifications or the roofer’s paperwork. It saves a wasted visit. We survey commercial flat roofs, roof terraces and balconies and green roofs, and common reasons people get in touch are gaps at membrane joints and breaches around outlets and penetrations.
Flat roofs on exposed homes in small places like Hudnall take more wind and rain, which is hard on edges, upstands and joins in the covering. Older felt roofs, frequently around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are typically the first part of a flat roof to go.
Pictures do a lot of the work in our reports, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

What we look for on each type of roof
Single-ply membranes
ELD often works on single-ply membranes, depending on the type and build-up.
Bituminous membranes
Bituminous felt and modified bitumen membranes are common. The build-up decides which method will work.
The survey, step by step
We don’t take risks to get a closer look. We inspect what can be seen safely, and if part of the roof cannot be seen, the report says so. Most visits take more time on a big roof than a small one, and the build-up of the roof makes a difference too. Older roofs in small places like Hudnall can have low, tight loft spaces, so it is useful to know whether there’s a loft hatch and how easy it is to reach. We only go where it’s safe.
- 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.
- The report is sent for your roofer to act on.
Preparing for the visit
- Have any questions written down, so nothing gets missed
- Show us where any leaks or stains appear
- Gather any invoices or paperwork from past roof work

Useful tips for Hudnall property owners
Here are a few things we’d tell any owner, before and after a survey:
- Do not keep patching the same spot
- Limit access to the roof
- Keep a note of leaks after rain
- Check trades protect the waterproofing
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
Ask trades working on the roof to protect the membrane when fitting equipment. Have the roof looked at after other work.
Hudnall questions
Do you cover smaller places like Hudnall?
Yes, smaller places are covered as well as towns. We work right across London and South East England. Just mention lanes, gates or anything else about the route when you book.
Does a conservation area affect roof work in Hudnall?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
How much does electronic leak detection cost?
Electronic leak detection is quoted for your roof, because the method depends on the roof. The price depends on the roof’s size and build-up. For a quote, ring 07833 053749 or send us an email.
Do you use drones?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.
How experienced are you?
We have more than 20 years’ experience and have carried out more than 5,000 surveys across London and the South East.
How soon will I get the report?
That depends on the survey you book: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. The report is emailed to you.
Can you give me structural calculations?
No. We’re experienced roof surveyors, and visible signs like sagging are noted, but we don’t provide calculations or an engineer’s opinion. If one is needed, the report says so.
Flat and commercial roofs around Hudnall
Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Listing and conservation areas can both shape what roof work is allowed on an older home. The council is the place to check, along with Historic England’s list, before anyone quotes for re-roofing.
If you own a rental within reach of Berkhamsted station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
