Electronic leak detection for homes and businesses in Great Wymondley
Our ELD testing covers flat roofs in Great Wymondley and the rest of London and the South East. A visit typically takes as long as needed for the membrane area and the build-up, which we set out in the quote. Every roof is quoted on its size and build-up. You get a written report with photos. If you’ve noticed leaking laps in the waterproofing and breaches around outlets and penetrations, a survey will tell you what’s going on, whatever the roof.
Some older homes in villages like Great Wymondley are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
The report records the flat roof membrane as we found it on the day. It is useful right away, and a good reference for later.

Flat and commercial roofs around Great Wymondley
The wider area around Great Wymondley has a long history of building, with Knebworth House about 4.9 miles south. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area. 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. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
The streets around a church such as Church of St Mary the Virgin are often among the oldest in a place, and if your home is one of the older ones nearby, the joins between later flat roofs and the old walls are where problems usually start.

What affects the price in Great Wymondley
Every roof is different, so prices are confirmed before you book. This is what makes a difference:
- Extensions, dormers and garages with roofs of their own
- If the survey needs thermal imaging or a drone
- How tall the building is and how easy the roof is to see
- How big the roof is
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before you book.

Great Wymondley: your questions answered
Do you cover Great Wymondley?
Yes. We work right across London and the South East, and Great Wymondley is part of that. You can call 07833 053749 or send us an email with the address and a few details, and we’ll talk through which survey suits.
Will you come out to Great Wymondley?
Yes, Great Wymondley is covered. We survey roofs across London and the South East, and smaller places are part of that. The journey is planned ahead, so it is useful to know about access.
Does the report include photographs?
Yes. We photograph the roof as we go, and the report uses them to show each finding.
Can you find leaks on a covered flat roof?
It can be possible, depending on the roof. Covered roofs limit the methods we can use, so we check the build-up first.
When does the report arrive?
That depends on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. Reports are sent by email.
How long have you been surveying roofs?
We have completed more than 5,000 surveys, over more than 20 years, and 98% of customers are satisfied.
Can you survey a shared roof?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we’re allowed to reach, and the report makes that clear.
Tips from our surveys
A little preparation and a few simple habits help. Our tips:
- Keep outlets clear of debris
- Check new waterproofing before handover
- Keep foot traffic on flat roofs to a minimum
- Check trades protect the waterproofing
You receive a report showing where each breach was found, with photos. Your roofer uses it to carry out repairs.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
Why get it checked now?
Some flat roof leaks come from walls or details. Testing shows whether the membrane is breached so attention can go to the right place. Around Great Wymondley, older homes often have old roof timbers, and water through a failed covering can rot timber if it’s left.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
Why book with us
- A sub-250g drone, flown with a CAA Flyer ID and Operator ID
- Insured for professional indemnity and public liability
