How electronic leak detection works in Monks Orchard
Our ELD testing covers flat roofs in Monks Orchard and the rest of London and the South East. A visit usually takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Every roof is quoted on its size and build-up. You get a photo-illustrated written report. Common reasons to book are new roofs to check before paving or planting and leaks through a flat roof with no obvious cause, across commercial flat roofs, roof terraces and balconies and single-ply roofs.
Offices, shops and blocks of flats across London often have large flat roofs with plant, rooflights and walkways. Each pipe, upstand and fixing through the covering is a possible weak point. For a building in Monks Orchard, access is agreed with whoever manages the roof ahead of the visit. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
The report is written in plain words, so you do not need to be a roofer to follow it. Each point is backed by a photo where possible, with the urgent items made clear.

What you can safely check yourself
You can learn a lot from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
It’s useful to keep a record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry.
Why get it checked now?
Not every leak is in the membrane. ELD helps rule the membrane in or out, so other causes can be checked. In Monks Orchard, as across London, an overflowing gutter soaks the wall below, which can lead to damp inside. A blocked outlet ignored for a winter or two can mean damp walls inside.
To find out what your survey will cost, ring 07833 053749 or email us with the address and a few details. We will confirm the figure before booking.

Electronic leak detection in Monks Orchard: local notes
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. The wider area around Monks Orchard has a long history of building, with Addington Palace about 1.8 miles south. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years.
If you own one of the older houses in the streets near St George The Martyr Church, flat-roofed rear additions and dormers added over the years are worth checking. Landlords with a home close to Elmers End station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.

FAQs for Monks Orchard
Do you carry out roof surveys in Monks Orchard?
Yes. Our area covers London and South East England, and Monks Orchard is part of that. You can phone 07833 053749 or send us an email with the address and a few details.
How do I find out if my home in Monks Orchard is listed?
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. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Is my roof suitable for ELD?
It depends on the membrane and the build-up. Share any details you have and we will confirm suitability.
Is the repair part of the test?
No. We test the membrane and report. The report shows where each breach is so your roofer can fix them.
What if it rains on the day?
It can, depending on the survey. Drone flights need calm, dry weather, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. If the conditions aren’t right, we will talk to you about another date.
Can you give me structural calculations?
No. Our survey isn’t a structural engineer’s report, and it does not include calculations. We’ll recommend an engineer if we see signs that call for one.
What happens next?
You receive the written report by email, with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
When to book a survey in Monks Orchard
When the membrane is buried, holes can’t be seen at all. Electronic methods can help on some of these roofs though it depends on the layers.
Signs worth acting on include:
- Gaps at membrane joints
- Water coming in under a flat roof
- Holes left by work on the roof
- Damp inside with no sign on the roof
Parking in Monks Orchard, as in most of London, takes a little planning: let us know about permits, visitor bays or off-street space as you book, as a space near the door can’t be promised.
Choosing a roof surveyor
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- What exactly goes into their report
- Whether the loft is part of the inspection
- What they will not be able to tell you
How the survey works
There isn’t much for you to do on the day. Show us any stains, drips or problem areas you know about, and we’ll take it from there. A typical survey takes a length of time set by the size of the roof and how it’s built, which we’ll explain when we quote. Many London properties are flats or terraces with no side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. Mention any building rules, key holders or managing agents when you book.
- We start by finding out what the roof is made of and where it leaks.
- The roof is assessed to see if electronic testing will work on it.
- We pick the low-voltage or high-voltage method that suits the roof.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
How to prepare
- Agree roof access with the managing agent if it is shared
- If you are buying, let the agent know when we are coming
- Jot down any questions you want answered
How to book
Every survey is priced before it is booked, so you know where you stand. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, phone 07833 053749 or drop us an email.
Advice
Honest limits
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Build-ups without a suitable layer below
- Carrying out the repair work
- Moisture spread under the membrane
