How electronic leak detection works in Bishop's Stortford
Electronic leak detection works on many flat roof membranes, on homes, blocks and commercial buildings. It helps trace a leak you already have or to test a new membrane before it is covered. Each roof is quoted on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays when conditions allow. Just ask about your roof. We are frequently asked to look into punctures from foot traffic or tools and failed seams and laps, on roof terraces and balconies, green roofs and flat roof membranes.
In a town like Bishop's Stortford, flat roofs are common on rear extensions, garages, porches and dormers. Older ones are frequently felt, which often lasts around 15–20 years, while newer ones may be EPDM rubber or GRP fibreglass. The usual warning signs are standing water, splits and edges coming away. Water that sits for days after rain is frequently the first sign a flat roof needs attention.
Where we cannot see part of the flat roof membrane, the report says so. You’ll know exactly what was inspected and what wasn’t, and what we’d suggest next.

FAQs for Bishop's Stortford
Is my home in Bishop's Stortford listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Is there anything to prepare before you come to Bishop's Stortford?
Clear the way to the loft hatch if there is one, and tell us about any leaks, stains or past repairs. Let us know about parking and access in Bishop's Stortford too.
Will you go up on the roof?
Only when it is safe. Some roofs are too steep or fragile to walk on safely. Safe viewpoints, the loft and a drone where it applies let us see the rest.
How is ELD priced?
We quote electronic leak detection for each roof, as the method and time depend on the roof. The price depends on the roof’s size and build-up. To get a quote, phone 07833 053749 or drop us an email.
How do you choose the testing method?
The method is chosen to suit the roof. Low-voltage testing normally needs a wet surface and high-voltage methods need the membrane dry and exposed.
Can you find leaks on a covered flat roof?
In some cases. The layers on top and the build-up below decide it and parts may need to be lifted. We talk this through first.
What’s the best way to book?
To book, ring 07833 053749 or use the contact form with the address, the type of property and what’s prompted the survey. We’ll confirm the price and find a day that suits.
What electronic leak detection looks like in Bishop's Stortford
About 3.6 miles west lies Much Hadham Palace, a reminder of how long the area around Bishop's Stortford has been built on. Older homes in the wider area frequently have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
Take an older house close to Church of St Michael: any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. Landlords with a home close to Bishops Stortford station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak. For site and facilities teams at buildings such as St Michael's Church of England Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

Tips from our surveys
Here are a few things we’d tell any owner:
- Act on new leaks promptly
- Do not keep patching the same spot
- Don’t let outlets block
- Tell us about the membrane and build-up if you know it
If we think the leak is not coming through the membrane, the report says so, so other causes can be checked.
Limit foot traffic on flat roofs. Feet and dropped tools are a common cause of holes.
What we can’t see
Our survey isn’t a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Carrying out the repair work
- The extent of water in the insulation
- Build-ups without a suitable layer below
If you are not sure which survey you need, call 07833 053749 or drop us an email and we’ll give you a straight answer before you book. The full list of what we check.
What we check
- Green roofs
- Commercial flat roofs
- Liquid-applied waterproofing
- Roof terraces and balconies
- Flat roof membranes
- Single-ply roofs
What affects the cost of electronic leak detection
To price your survey, we check:
- How complicated the roof is, with its valleys, chimneys and parapets
- Height and safe access
- If the survey needs thermal imaging or a drone
- Roof area
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before booking.
What we need to know
You do not need to know any roofing terms. It is enough to tell us:
- Your postcode, so we can check access and travel
- Any stains, drips or damp patches you’ve seen indoors
- Any deadline, such as an exchange date
- The style of property, from a terrace to a block
A quick phone call is normally the easiest start: call 07833 053749 or email us. The price is agreed before a date is set.
How the survey works
The visit has one job: to look at the flat roof membrane as closely as is safe and record what we find. Notes and photographs go into the written report. The visit usually takes longer on a large roof than a small one, with the construction of the roof playing a part too. Most visits in a town like Bishop's Stortford start at the front of the house and work round to the back. The back garden is often where extensions, dormers and rear slopes are best seen. Then, if it can be reached safely, we look in the loft.
- You tell us about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Preparing for the visit
- Check pets are kept safely away
- Jot down any questions you want answered
- Let us know about parking near the property

Advice
Why get it checked now?
Leaks left running can wet the insulation and deck. Finding the breach sooner limits that. In a family home in Bishop's Stortford, a small roof fault lets water into places you cannot see, such as the loft insulation, the top of a wall or the roof timbers. By the time it shows inside, the job has grown.
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You will know the exact price before booking.

Checking the roof from ground level
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That’s where a survey comes in, using safe viewpoints and a drone where applicable.
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
