About our electronic leak detection in Chalfont St Peter
Our ELD testing covers flat roofs in Chalfont St Peter and the rest of London and the South East. Testing usually takes more time on a big roof than a small one, with the construction of the roof playing a part too. Electronic leak detection is quoted for your roof, because the method depends on the roof. The results come in a written report with photos. Typical surveys look at leaks at pipes, outlets or fixings and leaks under green or ballasted roofs, on roof terraces and balconies, commercial flat roofs and liquid-applied waterproofing.
Around Chalfont St Peter, many homes have a garden room, garage or outbuilding with a flat roof. They’re easy to forget, but water through a garage roof can spoil whatever is stored inside. If you want them looked at too, mention them when you book. Smaller roofs use the same coverings as bigger ones, from felt to rubber and GRP, and age in the same way.
Findings are set out part by part, from the coverings down to the gutters, each with a short note and a photo. It records what’s sound as well as what isn’t.

Practical tips
You do not need to be a roofer to help. Here’s what helps most:
- Keep foot traffic on flat roofs to a minimum
- Note where leaks show inside and when
- Find the breach before more patching
- Let us know about the membrane and build-up if you know it
If water has been getting in, insulation under the membrane may be wet. That’s something to discuss with your roofer and other checks can help judge it.
Act on leaks quickly. Water under a membrane can spread.
What we do, step by step
Every roof is different, but as a rough guide the survey takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. You are welcome to ask questions while we are there. In a smaller place like Chalfont St Peter, as anywhere, the forecast plays a part: drone flights and thermal imaging need the right conditions, while a look from ground level and the loft can go ahead in most weather.
- You tell us about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photos shows where each breach is.
Preparing for the visit
- Leave side gates unlocked
- Jot down any questions you want answered
- Dig out any old roof reports or invoices
Getting a price
A quick phone call is typically the easiest start: call 07833 053749 or use the contact form, and we’ll ask about the building and what you need. The price is agreed before a date is set.
Advice
What electronic leak detection looks like in Chalfont St Peter
Historic houses such as Chenies Manor House, about 4.8 miles north, show how far back building in the area around Chalfont St Peter goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area. Some villages in Buckinghamshire still have thatched roofs. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Next to the main roofs there’s normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If you look after a building such as Chalfont St Peter CofE Academy, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. If your home is one of the older ones in the streets near Parish Church of St Peter, flat-roofed rear additions and dormers added over the years are worth checking.

When to book a survey in Chalfont St Peter
Work on the roof can damage a membrane. Fixings, equipment and foot traffic can leave small holes.
These are some of the problems a survey can pick up:
- New membranes needing a check before handover
- A flat roof leak that cannot be traced
- Failed seams and laps
- Holes left by work on the roof
If you own a rental within reach of Gerrards Cross station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

What affects the cost of electronic leak detection
What a survey costs depends on the time and equipment it needs. That comes down to:
- Height and safe access
- How complicated the roof is, with its valleys, chimneys and parapets
- House, block, shop or office
- Any need for thermal images or a drone flight
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.
Getting in touch
There is no need for technical words. Just tell us:
- Anything about access we should know
- Where water is showing inside, if it is
- What kind of property and roof it is
- What’s prompted the survey
Every survey is priced before it’s booked, so you know where you stand. Electronic leak detection is quoted for your roof, because the method depends on the roof. To book, phone 07833 053749 or drop us an email.
