Electronic leak detection in Henham: what you get
Electronic leak detection works on many flat roof membranes over offices, units, blocks of flats and homes. It helps trace a leak you already have or check a new membrane before handover. Each roof is quoted on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays, depending on the weather. Just ask about your roof. Typical surveys look at water coming in under a flat roof and damp inside with no sign on the roof, across commercial flat roofs, single-ply roofs and roof terraces and balconies.
Some older homes in villages like Henham 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. Listed building consent is needed for changes that affect a listed building’s special interest.
Findings are set out part by part, from the coverings down to the gutters, with a note and a photo for each point. It records what’s sound as well as what isn’t.

Electronic leak detection in Henham: local notes
The wider area around Henham has a long history of building, with Horham Hall about 2.7 miles east. 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. Weatherboarded walls and clay tile roofs are typical of older Essex buildings, alongside lots of post-war and newer estates. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
Anyone responsible for a site like Henham and Ugley Primary and Nursery School will know that a large flat roof with lots of outlets and rooflights has many places where a membrane can fail. If you own a rental within reach of Elsenham station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. Take an older house close to 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.
Henham is about 6 miles north-east of Bishop's Stortford, in Essex. Whether the building in Henham is a house, a flat or a commercial unit, the roof can be surveyed on a weekday or at the weekend. Our Essex coverage includes Henham. There’s also a page for Chelmsford.

Why it’s worth a survey now in Henham
Patching where you think the leak is often misses it. ELD shows the actual breach points. Where a roof is exposed, as many are in small places like Henham, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.

Roof by roof
Bituminous membranes
Bitumen roofs can frequently be tested electronically though the layers below matter.
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer, but can still have thin spots or holes. Whether ELD works depends on the coating and build-up.
How the survey works
Every roof is different, but as a rough guide the survey takes more time on a big roof than a small one, with the construction of the roof playing a part too. You’re welcome to ask questions while we’re there. Somewhere as small as Henham, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photos shows where each breach is.
Before the survey
- Have any questions written down, so nothing gets missed
- Keep pets in another room
- If it isn’t your property yet, arrange access through the agent
Book a survey
If you have photos of the roof, send them over. Pictures from the ground or a window are fine. To get started, ring 07833 053749 or email us.

What you can safely check yourself
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, which helps when we check the roof.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
Your questions about electronic leak detection in Henham
Do you carry out roof surveys in Henham?
Yes. We survey roofs across London and the South East, and Henham is part of that. You can ring 07833 053749 or use the contact form with the address and some details, and we’ll talk through which survey suits.
Is my home in Henham listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
How do I arrange electronic leak detection in Henham?
Just call 07833 053749 or send us an email. After a few questions, we confirm the price and fix a day, weekday or weekend.
Will I get photos?
Yes, plenty. Pictures sit next to the findings they show.
Does this replace a RICS home survey?
No. We’re experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you will need a RICS survey as well.
How soon will I get the report?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. Each one is emailed.
What if it rains on the day?
Light rain doesn’t usually stop a survey. Strong wind or heavy rain can stop drone flights and make roof access unsafe, so if conditions are not right we’ll arrange another day with you.
Landlord and commercial surveys in Henham
Where a roof is shared: access has to be agreed with whoever owns or manages the building. Mention it when you contact us and we will plan the survey around it.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, putting the urgent items at the top.
Before and after the survey
These tips come from what we see on roofs every week, before and after a survey:
- Keep foot traffic on flat roofs to a minimum
- Ask contractors to protect the membrane
- Share any drawings of the roof
- Consider ELD before paving or planting goes on
You receive a report showing where each breach was found, with photographs. Your roofer uses it to carry out repairs.
Limit foot traffic on flat roofs. Many breaches come from foot traffic.
