About our electronic leak detection in Potters Bar
ELD can be carried out in more than one way. Low-voltage methods normally need a wet roof surface, while high-voltage testing needs a dry, exposed membrane. The right method depends on the membrane and the build-up of the roof and we explain which we’ll use. If neither method suits your roof, we will tell you before any testing starts. If you’re worried about damage from equipment installers and a flat roof leak that can’t be traced, a survey will tell you what’s going on.
Houses around a town like Potters Bar often have a flat roof somewhere, over an extension, garage, porch or dormer. Many are felt, and newer ones may be EPDM rubber or GRP. The usual warning signs are standing water, splits and edges coming away. Water that sits for days after rain is often the first sign a flat roof needs attention.
The report does not just list problems. For each finding, it explains what it is, why it matters and what we’d recommend.

Potters Bar: your questions answered
Is Potters Bar in the area you cover?
Yes, Potters Bar is one of the places we work. The survey and report are the same in Potters Bar as anywhere else.
What do I need to do before a survey in Potters Bar?
The main thing is access, inside and out, plus somewhere to park in Potters Bar. Tell us about known leaks or past repairs as well.
What insurance do you have?
Every survey is covered by professional indemnity and public liability insurance, and details are available on request.
How soon will I get the report?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline as you book.
Is it the same as a RICS Level 2 or Level 3 survey?
No. This is a survey of the roof only, so it’s not a RICS Level 2 or Level 3 survey. Many buyers have both.
Will you photograph what you find?
Yes, every report has them. Each finding is shown in a picture where possible.
Can you inspect my roof with a drone?
Yes, where it’s applicable. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.
How the survey works
We do not take risks to get a closer look. We inspect everything that’s safely in view, 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, with the construction of the roof playing a part too. A survey in Potters Bar needs access inside and out, including the loft hatch and any rooms with damp. If there is a side gate or a rear garden, let us know how to reach it. Weekday and weekend visits are available.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photos shows where each breach is.
Preparing for the visit
- Make sure the loft hatch can be reached
- Leave side gates unlocked
- Make a note of anything you’d like us to look at

Advice
How we price electronic leak detection
Every roof is different, so prices are confirmed before booking. This is what makes a difference:
- The shape of the roof and its details
- The height of the building and how the roof can safely be seen
- Whether thermal imaging or a drone is needed
- The size of the roof
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You’ll know the price for your roof before you book.

Leave it or get it looked at?
Not every leak is in the membrane. Testing shows whether the membrane is breached, so other causes can be checked. On homes in Potters Bar, the joint between an extension and the house is where a slow leak tends to start. A few wet winters later, it can mean new plaster and decorating as well as roof work.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before booking.
Why book with us
- An independent view of the roof
- Two decades and more of roof surveys
- Every finding written up with photos
- Visits on any day of the week

Flat roofs in Potters Bar
With Wyllyotts Manor about 0.4 miles west, Potters Bar sits in an area with a long building history. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, 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 normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If you let a flat or house near Potters Bar station, the flat roof over a let home is worth a look before it becomes a tenant complaint. If you run a business near Spires Shopping Centre, the flat roofs over shops and commercial units are worth checking before a leak, not after. For an older house near a landmark such as St. Mary's Church, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
