Electronic leak detection in Shenley
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small electrical current that passes through the membrane only where there is a breach. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. You get a written report with photos of each breach found. We survey commercial flat roofs, flat roof membranes and roof terraces and balconies, and the problems we are asked to look at most are failed seams and laps and leaks under green or ballasted roofs.
Around Shenley, many homes have a garden room, garage or outbuilding with a flat roof. They’re rarely looked at until something gets wet. It’s worth mentioning them when you book, so the visit can include them, along with the main flat roof. Felt, rubber and GRP coverings on garages and outbuildings age in just the same way as the main roof’s.
The report does not just list problems. It explains what we found, why it matters and what we recommend, so you can plan your next steps.

Electronic leak detection in Shenley: local notes
The wider area around Shenley has a long history of building, with Wyllyotts Manor about 4.1 miles east. 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. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
For site and facilities teams at buildings like Shenley Primary School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. Take an older house close to Church of St Martin: later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear.
Shenley is about 2 miles north of Borehamwood, in Hertfordshire. Shenley gets the same service as everywhere else we work: a careful inspection, photographs and a written report. Our Hertfordshire coverage includes Shenley and the places around it. Our London page covers surveys nearby.

What we are asked to look at in Shenley
Holes in a membrane often come from feet, tools or debris. Many are tiny, but still let water through.
It’s worth booking a survey if you’ve seen:
- Repairs that haven’t stopped the leak
- Damage from equipment installers
- Leaks showing away from the breach
- Leaks through a covered membrane
If you own a rental within reach of Radlett station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
What to check before booking
- Will they check the loft as well as the outside?
- What the report includes, and whether it has photos
- Their track record with similar roofs
- Is there a chance to talk the report through?
Landlord and commercial surveys in Shenley
With a portfolio of properties, you can book surveys for several addresses. To discuss a number of properties, phone 07833 053749 or email us.
Roof problems in a rented home affect tenants as well as the building. A survey shows what needs attention, so you can plan the work around your tenants.
How the survey works
There is not much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll take it from there. A typical survey takes a time that depends on the roof’s area and construction, which we’ll explain when we quote. Homes around Shenley often have gardens on more than one side, which gives us room to step back and see the roof. Let us know if any side is fenced off or hard to reach. Inside, the loft is looked at where it can be reached safely.
- You let us know 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.
- We test the roof and locate any breaches.
- A report with photographs shows where each breach is.
Before the survey
- Check pets are kept safely away
- Make a note of anything you’d like us to look at
- Make sure the loft hatch can be reached
How to book
If you have photos of the roof, send them over. Take them safely from the ground or a window; never climb up to get a better view. To send them or to book, call 07833 053749 or drop us an email.
Advice
What happens if roof problems are left?
Not every leak is in the membrane. Testing shows whether the membrane is breached so attention can go to the right place. In a smaller place like Shenley, wherever a roof is exposed, a loose ridge or flashing does not stay loose for long. Each storm lifts it a little further, and water follows.
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You will know the exact price before you book.
What you get with us
- Drone and thermal imaging surveys available
- We hold a CAA Flyer ID and Operator ID

Your questions about electronic leak detection in Shenley
Do you cover smaller places like Shenley?
Yes, Shenley is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Is Shenley in the area you cover?
Yes. We work right across London and South East England, and Shenley is part of that. Just ring 07833 053749 or email us and let us know about the property.
Will I get photos?
Yes, plenty. Pictures sit next to the findings they show, which makes the report easy to follow.
What insurance do you have?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
Is this a RICS survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof and can sit alongside a RICS survey.
How long will testing take?
It depends on the size of the roof and its build-up. We’ll give you an idea when we quote.
Will you fly a drone over my roof?
Where it helps and it’s safe, yes. Flights depend on the weather on the day and airspace rules, including flight restriction zones near airports. We hold a CAA Flyer ID and Operator ID.
Practical tips
Here are a few things we’d tell any owner:
- Keep a note of leaks after rain
- Share any drawings of the roof
- Check new waterproofing before handover
- Keep foot traffic on flat roofs to a minimum
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. Check the roof after they’ve finished.
