Electronic leak detection for homes and businesses in Stotfold Common
ELD finds breaches in the membrane but not every way water gets in. Leaks from walls, copings, rooflights or pipes need other checks. We’ll tell you if we think the leak is coming from somewhere else. The test shows breaches in the membrane, not water coming through masonry or around frames. Our report keeps that distinction clear. You’ll also know what to check next. Typical surveys look at gaps at membrane joints and waterproofing to test before it’s covered, across roof terraces and balconies, liquid-applied waterproofing and flat roof membranes.
Some older homes in villages like Stotfold Common are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you are planning work, check with the council first. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.
We keep jargon out of it: if work is needed, the report says so clearly.

Questions from Stotfold Common
Is my home in Stotfold Common 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.
Do you carry out roof surveys in Stotfold Common?
Yes, Stotfold Common is within the area we cover. We survey roofs across London and the South East. You can ring 07833 053749 or send us an email with the address and a few details, and we’ll talk through which survey suits.
What insurance do you have?
We’re covered by professional indemnity and public liability insurance.
What’s in the report?
It sets out what we found, why it matters and what we recommend, with photographs throughout. Anything we couldn’t see safely is noted too.
How does ELD work?
It uses an electrical current to find breaches in a flat roof membrane. A breach lets the current through so we can pinpoint it.
Do you climb onto every roof?
Only when it is safe. Safe viewpoints, the loft space and a drone where it applies cover most of what’s needed, and the report notes anything we couldn’t see.
What if it rains on the day?
It can, depending on the survey. Drone flights need calm, dry weather, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. If the conditions aren’t right, we’ll talk to you about another date.

Tips from our surveys
A few practical points come up again and again on our surveys. They apply to most roofs:
- Note where leaks show inside and when
- Ask contractors to protect the membrane
- Avoid repeated repairs without finding the cause
- Get leaks traced quickly
File the report with your roof paperwork. It shows the condition of the membrane on that date.
Consider testing a new membrane before it is covered. It is easier to find holes before more layers are added.
Electronic leak detection in Stotfold Common: local notes
Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. About 1.8 miles north-east lies Hinxworth Place, a reminder of how long the area around Stotfold Common has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs.
The streets around a church such as Church of Saint Guthlac are often among the oldest in a place, and if your home is one of the older ones nearby, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. If you look after a building such as St Mary's CofE Academy Stotfold, a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.
Stotfold Common is about 3 miles north of Letchworth, in Hertfordshire.

Roof by roof
EPDM rubber roofs
EPDM rubber roofs often last 30–50 years, but can still be punctured.
Green and ballasted roofs
Testing before planting or ballast goes on is simpler.
What electronic leak detection does not cover
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:
- Moisture spread under the membrane
- Build-ups without a suitable layer below
- Carrying out the repair work

What happens on the day
The visit normally starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. All told, expect a length of time set by the membrane area and the build-up, which we’ll explain when we quote. Cottages and farmhouses around Stotfold Common often have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can safely be seen, and anything we cannot see is noted.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
Getting ready for the survey
- Unlock side gates and any roof access doors
- Point out any leaks or damp patches

Common roof problems in Stotfold Common
Repeated leaks after repairs suggest the real breach hasn’t been found. Electronic testing helps pinpoint it.
Look out for signs like these:
- Repairs that haven’t stopped the leak
- New membranes needing a check before handover
- A flat roof leak that can’t be traced
- Holes left by work on the roof
Landlords with a home close to Arlesey station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.
What to check before booking
- What happens after the report arrives
- Do they have a CAA Flyer ID and Operator ID for drone work?
- How they plan to inspect the roof safely
- Their insurance cover
What happens if roof problems are left?
Some breaches are too small to see. Electronic testing can find breaches you can’t see by eye where the roof suits it. Around Stotfold Common, older homes frequently have old roof timbers, and water through a failed covering can rot timber if it’s left.
