Electronic leak detection in Elmdon: what you get
ELD can be carried out in more than one way. Low-voltage methods typically need a wet roof surface, while high-voltage testing needs a dry, exposed membrane. The right method depends on the membrane and the build-up of the roof and we explain which we’ll use. We will say if your roof doesn’t suit either method at the outset. Typical surveys look at stains far from any visible defect and leaks at pipes, outlets or fixings, on commercial flat roofs, liquid-applied waterproofing and single-ply roofs.
Somewhere as small as Elmdon, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included as you book.
What you get is a clear record of the flat roof membrane on the day we saw it. It is useful right away, and a good reference for later, such as when you want to compare after future work.

Elmdon: your questions answered
How do I find out if my home in Elmdon is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Will you come out to Elmdon?
Yes, Elmdon is covered. Our area covers London and South East England, and smaller places are part of that. The journey is planned ahead, so it is useful to know about access.
Does the weather affect the survey?
Light rain is normally fine; heavy rain and wind are different. In high wind or heavy rain, a drone cannot fly and access may not be safe, and we’d agree another day.
What’s in the survey report?
It works through the roof part by part, in writing and with photos, finishing with recommendations. The most urgent items are made clear.
Which method do you use?
The method is chosen to suit the roof. Low-voltage methods are usually carried out on a wet roof and high-voltage methods need the membrane dry and exposed.
How does ELD work?
ELD passes a small electrical current across the roof to locate holes in the membrane. The current only gets through where the membrane is breached, which shows us where the hole is.
How much does electronic leak detection cost?
Each roof is quoted on its size and build-up. Send us details of the roof. Just phone 07833 053749 or drop us an email for a quote.
What you can safely check yourself
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can point to a blockage or a sagging run.
Do you need electronic leak detection in Elmdon?
Other trades on the roof can puncture the waterproofing. Fixings, equipment and foot traffic can leave small holes.
Here are some of the things we see often:
- Leaking laps in the waterproofing
- New roofs to check before paving or planting
- Leaks at pipes, outlets or fixings
- Leaks under green or ballasted roofs
Take an older house close to Church of St Nicholas: flat-roofed rear additions and dormers added over the years are worth checking.
What to check before booking
- How long they’ve been surveying roofs
- Whether they hold professional indemnity and public liability insurance
- Which viewpoints they use to see the roof
- Is there a chance to talk the report through?
How it works
The visit has one job: to look at the flat roof membrane as closely as is safe and record what we find. Notes and photographs go into the written report. The visit normally takes a time that depends on the size of the roof and how it’s built, and we’ll give you a guide when quoting. For a village or hamlet like Elmdon, the journey is planned beforehand: let us know about lanes, gates and parking. The roof is looked at from ground level, from windows, from the loft where there’s safe access and from the roof where it is safe.
- 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.
- You get a report with photos of each breach.
Getting ready for the survey
- Note where any stains or damp appear
- Let us know where we can park nearby
- Agree roof access with the managing agent if it is shared
Getting a price
Most bookings start with a short call: ring 07833 053749 or drop us an email and we will ask a few questions about the roof. You’ll have a price before anything is arranged.

What else we do in Elmdon
Flat and commercial roofs around Elmdon
Weatherboarded walls and clay tile roofs are typical of older Essex buildings, with post-war and more recent estates making up much of the newer housing. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. About 3.9 miles east lies Audley End House, a reminder of how long the area around Elmdon has been built on. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material.
Landlords with a home close to Great Chesterford station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.

Practical tips
A few practical points come up again and again on our surveys. They apply to most roofs:
- Note where leaks show inside and when
- Clear flat roof outlets regularly
- Act on new leaks promptly
- Ask contractors to protect the membrane
After your roofer repairs the breaches, a retest can confirm them if the build-up allows.
Consider testing a new membrane before it’s covered. It is easier to find holes before more layers are added.
