Electronic Leak Detection in Stotfold
A careful look at the flat roof membrane at your property in Stotfold, and put it all in a written report with photos.
- Leaks that return after repairs
- Holes around roof penetrations
- Damage from equipment installers
Before and after the survey
A survey works best with a little help from you, before and after. Some tips:
- Clear flat roof outlets regularly
- Stay off the flat roof unless needed
- Use boards when working on the roof
- Avoid repeated repairs without finding the cause
If anything in the report isn’t clear, ask us. We will explain what was found and what it means.
Don’t leave a flat roof leak running. Water under a membrane can spread.
Electronic leak detection for homes and businesses in Stotfold
Electronic testing locates holes in the waterproofing, not every cause of water getting in. Water coming through walls, copings, rooflights or plumbing will not show on the test. If the evidence points elsewhere, we’ll say so. The test shows breaches in the membrane, not water coming through masonry or around frames. The report makes clear what was and wasn’t tested. We will point you to the likely next step. Typical surveys look at a flat roof leak that can’t be traced and leaks at pipes, outlets or fixings, across single-ply roofs, roof terraces and balconies and green roofs.
Outbuildings, garden rooms and garages in places like Stotfold often have flat roofs of their own. They’re easy to forget, but water through a garage roof can spoil whatever is stored inside. 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.
It isn’t only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

How the survey changes by roof type
Liquid-applied waterproofing
Pinholes in a coating can let water through. ELD can help locate them on suitable roofs.
EPDM rubber roofs
ELD on EPDM depends on the product and the layers. We check this first.
What electronic leak detection looks like in Stotfold
Historic houses such as Hinxworth Place, about 2.4 miles north-east, show how far back building in the area around Stotfold goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, 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. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If you let a flat or house near Arlesey station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. For an older house near a landmark such as Church of St Mary the Virgin, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

What happens if roof problems are left?
Some breaches are too small to see. ELD picks up breaches a visual check might miss, on suitable membranes. With lower homes, common in places like Stotfold, there is little between a roof defect and the ceiling, so water can show inside quickly once it gets past the covering. Catching the cause first saves redecorating as well.
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You will know the price for the job before you book.

FAQs for Stotfold
Do you cover Stotfold?
Yes, Stotfold is one of the places we work. The survey and report are the same in Stotfold as anywhere else, and visits run on weekdays and weekends.
Is my home in Stotfold listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Does the report include photographs?
Yes. The report includes photos of what we found.
How long does electronic leak detection take?
It normally takes longer on a large roof than a small one, and the build-up of the roof makes a difference too.
Is the repair part of the test?
No. We test the membrane and report. The report shows where each breach is for your roofer to repair.
Can every flat roof be tested?
It depends on the membrane and the build-up. Let us know what you know about the roof and we will confirm suitability.
Do you climb onto every roof?
Only when it is safe. Safety comes first, and fragile or steep roofs can’t always be walked on. Safe viewpoints, the loft and a drone where it applies let us see the rest, and the report records anything we couldn’t see.
What affects the price in Stotfold
A few things affect what a survey costs:
- The size of the roof
- Whether it is a home or a commercial building
- How many separate roofs there are, such as extensions, dormers and garages
- Features like valleys, chimneys, dormers and parapets
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You will know the figure before booking.
Booking your survey
If you can, have these to hand when you get in touch:
- Access details, like a loft hatch or a shared roof
- Where water is showing inside, if it is
- Any photos you have, taken from the ground or a window
- The kind of building and roof involved
Our phone lines are open seven days a week. To book or ask a question, phone 07833 053749 or send us an email.
What we’re asked to look at in Stotfold
Joints and laps in a membrane can fail over time. A gap that’s hard to see can let water in for months before it shows.
Here are some of the things we see frequently:
- Repairs that haven’t stopped the leak
- Holes left by work on the roof
- Leaks at pipes, outlets or fixings
- Waterproofing to test before it’s covered
If you look after a building like Roecroft Lower School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Before you book any roof surveyor

- Their report turnaround times

The survey, step by step
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. The inspection then takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Parking around Stotfold is usually easier than in a town centre, but mention lanes, gates or long drives. Low roofs on bungalows can often be seen well from ground level, and the loft shows the rest, while taller roofs may need other vantage points or the drone where it applies.
- We start with what you know about the roof and the leak.
- 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.
- A report with photos shows where each breach is.
Preparing for the visit
- If you’re buying, let the agent know when we’re coming
- Find any records of previous roof work
- For flats, make sure roof access has been agreed
