Electronic leak detection in Chapmore End, Hertfordshire
Wondering about the flat roof membrane at a property in Chapmore End? We carry out electronic leak detection in Chapmore End and across Hertfordshire, with plain-English findings.
- Breaches around outlets and penetrations
- Punctures from foot traffic or tools
- Waterproofing to test before it is covered
Roof by roof
Inverted and paved roofs
If the build-up rules out ELD, we’ll say so.
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer, but can still have thin spots or holes. Suitability for ELD depends on the system.
How electronic leak detection works in Chapmore End
ELD suits many waterproofing membranes on flat roofs over offices, units, blocks of flats and homes. It helps trace a leak you already have or to test a new membrane before it is covered. Each roof is quoted on its size and build-up. We can test on weekdays and at weekends, depending on the weather. Tell us about your roof to find out more. Common reasons to book are water coming in under a flat roof and leaks showing away from the breach, on green roofs, roof terraces and balconies and liquid-applied waterproofing.
Flat roofs on exposed homes in small places like Chapmore End take more wind and rain, so edges, upstands and laps take a beating. Older felt roofs, frequently around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are normally the first part of a flat roof to go.
Every survey ends with a written report, with photographs, emailed to you. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

What this survey can’t tell you
Some things can’t be seen without opening up the roof, and that sets some limits:
- Water entering through details rather than the membrane
- Some conductive membranes
- Moisture spread under the membrane

Flat and commercial roofs around Chapmore End
About 4.9 miles north-west lies Aston Bury, a reminder of how long the area around Chapmore End has been built on. 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 the council can say whether a home is in a conservation area. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If you look after a building like Tonwell St Mary's Church of England Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. Landlords with a home close to Hertford East station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.

What a survey costs
Not every roof costs the same to survey, and it comes down to:
- The use of thermal imaging or a drone
- Whether it’s a home or a commercial building
- Extra roofs, like extensions, dormers or garages
- The height of the building and how the roof can be seen safely
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before booking.
Getting in touch
These details help when you get in touch:
- Where any leaks, stains or damp patches show inside
- Photos of the roof, taken safely from the ground or a window
- How the loft is reached, if there is one
- What made you get in touch
We confirm the price for the job before you book, so you know the cost up front. Electronic leak detection is quoted for your roof, because the method depends on the roof. To book, phone 07833 053749 or send us an email.
Common questions in Chapmore End
Does a conservation area affect roof work in Chapmore End?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do you cover Chapmore End?
Yes, Chapmore End is within the area we cover. We cover the whole of London and South East England. You can phone 07833 053749 or use the contact form with the address and some details.
Which method do you use?
The method is chosen to suit the roof. Low-voltage testing typically needs a wet surface and high-voltage methods need the membrane dry and exposed.
Can you find leaks on a covered flat roof?
It can be possible, depending on the roof. What sits on the membrane affects the method so we look at the roof first.
Is it the same as a RICS Level 2 or Level 3 survey?
No. This is a survey of the roof only, and it isn’t a RICS Level 2 or Level 3 survey. Many buyers have both.
Do you use drones?
Yes, where it’s applicable. Whether we can fly on the day depends on the weather and the airspace rules, including flight restriction zones near airports. We’re a CAA-registered drone operator.
Can every flat roof be tested?
That depends on the roof’s membrane and layers. Share any details you have and we will confirm suitability.
What we do, step by step
We photograph the roof as we go, so you can see in the report what we found and where. We take close-ups from wherever is safe, including by drone where it is applicable and the weather allows. Most surveys take a length of time set by the roof’s area and construction, which we’ll explain when we quote. Older roofs in small places like Chapmore End can have low, tight loft spaces, so it helps to know whether there is a loft hatch and how easy it is to reach. We only go where it is safe.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
How to prepare
- Clear the way to the loft hatch
- Have any paperwork from past roof work to hand
- Have any questions written down, so nothing gets missed
Booking a survey

Related advice
Leave it or get it looked at?
Some breaches are too small to see. Electronic testing can find breaches you cannot see by eye where the roof suits it. Older cottages and farmhouses around Chapmore End can have roof timbers that have been there a very long time, where water from a failed roof can cause rot 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 safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.

Should I look at the roof myself first?
What you can’t do safely is get up close. Roofs are fragile and slippery. That is where a survey comes in, using safe viewpoints and a drone where applicable.
Your own check is a good start, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are frequently out of sight.
