Electronic leak detection in Little Wymondley, Hertfordshire
Find out what’s going on with the flat roof membrane before you decide what to do next. We carry out electronic leak detection in Little Wymondley.
- Stains far from any visible defect
- Leaks through a covered membrane
- A flat roof leak that can’t be traced
How electronic leak detection works in Little Wymondley
Roofs covered with paving, ballast or planting need more thought. What sits on the membrane can affect which method will work, and some may need lifting. We’ll discuss it with you when we quote. Any details of the build-up help, as they show what lies beneath the surface. We will tell you if the roof cannot be tested. Common reasons to book are stains far from any visible defect and punctures from foot traffic or tools, on flat roof membranes, roof terraces and balconies and single-ply roofs.
Somewhere as small as Little Wymondley, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. We simply plan the journey and access beforehand. If there are outbuildings or garages with flat roofs, mention them when booking.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. That way, it’s clear what was covered and what wasn’t, and what we’d suggest next.

Common roof problems in Little Wymondley
Work on the roof can damage a membrane. Fixings, equipment and foot traffic can leave small holes.
A survey makes sense if you’ve noticed:
- A flat roof leak that cannot be traced
- Leaks showing away from the breach
- Punctures from foot traffic or tools
- Leaks under green or ballasted roofs
If you live in an older home near Church of St Mary the Virgin, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
What to check before booking
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- How long they’ve been surveying roofs
- What exactly goes into their report
- Whether the price includes VAT
What happens if roof problems are left?
Some breaches are too small to see. ELD picks up breaches a visual check might miss where the roof suits it. Where a roof is exposed, as many are in small places like Little Wymondley, driving rain gets into any weakness, and damp in older walls is slow to dry out.

How the survey works
The visit has one job: to see as much of the flat roof membrane as can be seen safely and record it clearly. Notes and photos go into the written report. The visit typically takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Older roofs in small places like Little Wymondley can have low, tight loft spaces, so it is useful to know whether there is a loft hatch and how easy it is to reach. We only go where it’s safe.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- 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 the survey
- Find any records of previous roof work
- If it isn’t your property yet, arrange access through the agent
- Make a note of anything you’d like us to look at
Booking a survey
We survey roofs seven days a week. To arrange a day that suits you, call 07833 053749 or send us an email with the address and the days you’d prefer.

Common questions in Little Wymondley
Do you cover smaller places like Little Wymondley?
Yes, Little Wymondley is on our map. A small place gets exactly the same survey as a big one.
Is my home in Little Wymondley listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Does someone need to be in?
Someone needs to let us in if we are looking inside or in the loft. We’ll talk about access as you book.
Will you photograph what you find?
Yes. Photos are taken throughout the survey, and they go into the written report.
Can you survey at the weekend?
Surveys run on any day of the week. To arrange a date, phone 07833 053749 or drop us an email.
Can you inspect my roof with a drone?
Yes, where it is applicable. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and every flight depends on the airspace and the weather.
Do you look in the loft space?
If there is a loft and safe access to it, yes. From inside, the underside of the roof frequently shows damp, staining or daylight that can’t be seen from outside.
DIY checks: what’s safe
Keep a simple record: dates of leaks, photos from the ground and any work done on the roof. Share it with us when you book.
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That is where a survey comes in.
Tips from our surveys
You don’t need to be a roofer to help. What helps most:
- Clear flat roof outlets regularly
- Don’t leave water getting in
- Check new waterproofing before handover
- Keep a note of leaks after rain
The report records each breach location with photos. Pass it to your roofer to repair the breach points.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.

What else we do in Little Wymondley
Flat roofs in Little Wymondley
With Knebworth House about 4.2 miles south, Little Wymondley sits in an area with a long building history. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If you own a rental within reach of Hitchin station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. If you look after a building like Wymondley Junior Mixed and Infant School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
