About our electronic leak detection in Great Waltham
ELD finds breaches in the membrane but not every way water gets in. Water coming through walls, copings, rooflights or plumbing won’t show on the test. We’ll tell you if we think the leak is coming from somewhere else. It will not show water getting in through brickwork or around frames. Our report keeps that distinction clear. You will also know what to check next. Typical surveys look at breaches hidden under paving or planting and waterproofing to test before it’s covered, across green roofs, roof terraces and balconies and flat roof membranes.
Somewhere as small as Great Waltham, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: outlets, upstands, edges and the covering itself. We simply plan the journey and access beforehand. Garages and outbuildings are easy to forget, so mention any you want included when booking.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

Some single-ply membranes suit electronic testing well but it depends on the product and layers.
Inverted and paved roofs
A terrace or paved roof hides the waterproofing. Suitability depends on the layers.
Great Waltham: your questions answered
Do you cover smaller places like Great Waltham?
Yes, Great Waltham is covered. Our area covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it’s useful to know about access.
How do I find out if my home in Great Waltham is listed?
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.
Can you give me structural calculations?
No. We’re roof surveyors, not structural engineers. We’ll recommend an engineer if we see signs that call for one.
Do you use drones?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and every flight depends on the airspace and the weather.
When does the report arrive?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. All of them come by email.
Are you insured?
Every survey is covered by professional indemnity and public liability insurance, and we can provide details if a managing agent needs them.
What does the report include?
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.
Flat roofs in Great Waltham
If your home is older, it is worth knowing whether it is listed or in a conservation area before planning roof work. Listed building consent covers changes to a listed building’s special interest, and an Article 4 direction can bring extra controls in a conservation area. Clay tiles and timber weatherboarding mark out many of the older buildings in Essex, and a good many post-war and modern estates besides. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If your home is one of the older ones in the streets near Church of SS Mary and Laurence, the flat roofs on later extensions tend to wear out long before the main roof. Anyone responsible for a site like Chelmer Valley High School will know that schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks. If you let a flat or house near Beaulieu Park station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Great Waltham is about 4 miles north of Chelmsford, in Essex. From houses to flats and shops in Great Waltham, we can survey the roof on a weekday or at the weekend. Great Waltham is one of the towns and villages in Essex we cover for electronic leak detection.

The survey, step by step
Before we start, let us know why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. The visit usually takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Cottages and farmhouses around Great Waltham 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 tell us about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photographs shows where each breach is.
Getting ready for the survey
- Note where any stains or damp appear
- Tell us about parking before the day
- Make sure the loft hatch can be reached

Checking the roof from ground level
You can learn a lot from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
Your own check is a good start, but it isn’t a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground.
Useful tips for Great Waltham property owners
A survey works best with a little help from you, before and after. Tips:
- Use boards when working on the roof
- Check new waterproofing before handover
- Share any drawings of the roof
- Keep a note of leaks after rain
File the report with your roof paperwork. It is a dated record of the membrane’s condition.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.

Prices for electronic leak detection in Great Waltham
Not every roof costs the same to survey, for these reasons:
- The use of thermal imaging or a drone
- Features like valleys, chimneys, dormers and parapets
- How tall the building is and how easy the roof is to see
- Extensions, dormers and garages with roofs of their own
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You’ll know the figure before booking.
What we need to know
Before you get in touch, it is useful to have:
- The style of property, from a terrace to a block
- Pictures from the garden or a window, if you have them
- What made you get in touch
- Access details, like a loft hatch or a shared roof
Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. For any other survey, just call 07833 053749 or use the contact form when you are ready.
Why it’s worth a survey now in Great Waltham
Some breaches are too small to see. Electronic testing can find breaches you can’t see by eye, on suitable membranes. In a place like Great Waltham, a barn or garage roof left to fail puts whatever is inside at risk. It’s worth including them in a survey before a winter does the damage.
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the exact price before booking.
