Electronic leak detection around Birchanger
Birchanger has a number of hotels within about a mile and a half, and like offices and blocks, hotels frequently sit under flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For an older house near a landmark such as Church of St Mary, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. If you run a hotel or guest house in or near Birchanger, a roof problem can mean rooms out of use.

How electronic leak detection works in Birchanger
Electronic testing locates holes in the waterproofing, not every cause of water getting in. Water coming through walls, copings, rooflights or plumbing won’t show on the test. If the evidence points elsewhere, we will say so. It will not show water getting in through brickwork or around frames. The report makes clear what was and wasn’t tested. You will also know what to check next. If you’re worried about gaps at membrane joints and damp inside with no sign on the roof, a survey will tell you what’s going on, on roof terraces and balconies, liquid-applied waterproofing and single-ply roofs alike.
In a small place like Birchanger, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, typically show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
The report records the flat roof membrane as we found it on the day. It’s useful straight away, and a good reference for later.

Different roofs, different checks
Liquid-applied waterproofing
Small holes in liquid waterproofing may leak. Where the roof suits it, testing can find them.
Inverted and paved roofs
We’ll tell you if your inverted or paved roof isn’t suitable.
What we’re asked to look at in Birchanger
On a flat roof, water spreads under the waterproofing. The stain inside can be far from the hole which makes it hard to find by looking.
Typical things we are asked to look at include:
- Breaches hidden under paving or planting
- Leaks at pipes, outlets or fixings
- Damage from equipment installers
- New roofs to check before paving or planting
If you let a flat or house near Stansted Mountfitchet station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Birchanger: your questions answered
Is Birchanger within the area you cover?
Yes, we do. Our area covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
How do I find out if my home in Birchanger is listed?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
What does electronic leak detection do?
It uses an electrical current to find breaches in a flat roof membrane. A breach lets the current through, which shows us where the hole is.
Is this an asbestos survey?
No. We can flag materials that might contain asbestos, but only a specialist asbestos surveyor can confirm it. Buildings built or refurbished before 2000 may contain it.
Will you walk on the roof?
Only when it’s safe. Safe viewpoints, the roof space and a drone where it applies cover most of what’s needed, and anything out of sight is recorded in the report.
What will the report tell me?
You get our findings in writing, part by part, with photos, and ends with what we recommend. The most urgent items are made clear.
How long have you been surveying roofs?
Over 5,000 surveys so far, across 20+ years of surveying roofs.
How the survey works
The aim of the visit is simple: to look at the flat roof membrane as closely as is safe and record what we find. Notes and photos go into the written report. The visit typically takes a time that depends on the size of the roof and how it’s built, which we’ll explain when we quote. Somewhere like Birchanger needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. On the day, we inspect whatever is safely visible, inside and out.
- We start by finding out what the roof is made of and where it leaks.
- We confirm whether the roof is suitable for electronic testing.
- The testing method is chosen to suit the membrane and build-up.
- Testing runs across the roof to locate breaches in the membrane.
- You get a report showing where each breach is, for your roofer to repair.
How to prepare
- Let us know about any leaks, stains or damp patches you know of
- If the roof is shared, arrange access with whoever manages the building
- Have any paperwork from past roof work to hand
Getting a price
A quick phone call is usually the easiest start: call 07833 053749 or send us an email. You’ll have a price before anything is arranged.
Advice
DIY checks: what’s safe
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, which helps when we check the roof.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.

Why it’s worth a survey now in Birchanger
ELD before paving, ballast or planting goes on is simpler. Once layers are added, finding a breach is harder. Matching old materials, like handmade tiles or stone slates, can take time to source. Spotting a problem early leaves room to find them.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before booking.

Tips that help
Small things make a difference, both for the survey and for the roof itself. Our tips:
- Don’t let outlets block
- Find the breach before more patching
- Test new membranes before covering them
- Don’t leave water getting in
If anything in the report is not clear, ask us. We can talk you through the findings.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
