What we do, step by step
The aim of the visit is simple: to look at the flat roof membrane as closely as is safe and record what we find. Everything we note and photograph goes into the written report. It typically takes a length of time set by the membrane area and the build-up, which we’ll explain when we quote. In a small place like Roe End, access is normally the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- 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.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Before we arrive

Electronic leak detection for homes and businesses in Roe End
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It works with an electrical current that passes through the membrane only where there is a breach. It can find holes too small to spot by eye so your roofer knows exactly where to repair. You get a written report with photographs of each breach found. We survey roof terraces and balconies, single-ply roofs and flat roof membranes, and common reasons people get in touch are leaks through a covered membrane and leaks that return after repairs.
Flat roofs on exposed homes in small places like Roe End take more wind and rain, which is hard on edges, upstands and joins in the covering. Older felt roofs, often around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are normally the first part of a flat roof to go.
The report does not just list problems. It explains what we found, why it matters and what we recommend, so you can plan your next steps.

Why get it checked now?
Repeated call-outs for the same leak add up. A report showing the breach points gives your roofer a clear target. In a small place like Roe End, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

FAQs for Roe End
Is Roe End in the area you cover?
Yes, Roe End is within the area we cover. We cover the whole of London and South East England. You can call 07833 053749 or email us with the address and a few details.
Do you cover smaller places like Roe End?
Yes. Roe End is within the area we cover, which takes in towns, villages and rural addresses. Our area covers London and the South East. Let us know about access, parking and anything unusual about getting there as you book.
Does electronic leak detection work on all membranes?
ELD doesn’t suit every roof. Certain membranes are conductive and some roofs lack the layer the test needs. If your roof won’t work, we’ll say so before testing.
Will I get photos?
Yes. We photograph the roof as we go, and they go into the written report alongside our recommendations.
Will you fly a drone over my roof?
Yes, where it is applicable. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.
Do you look in the loft space?
Yes, where the survey calls for it and there’s safe access. We look for staining, damp, daylight and signs of movement, as far as the space allows.
What happens after the survey?
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.
Electronic leak detection in Roe End: local notes
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, and flat-roofed additions turn up almost everywhere. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. Listing and conservation areas can both shape what roof work is allowed on an older home. Your council and Historic England’s list will tell you where you stand.
Take an older house close to Markyate Methodist Church: the joins between later flat roofs and the old walls are where problems typically start. Anyone responsible for a site like Markyate Village School and Nursery will know that a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.

Joints and laps in a membrane can fail over time. A gap that’s hard to see can let water in for months before it shows.
Typical things we’re asked to look at include:
- Leaks under green or ballasted roofs
- Stains far from any visible defect
- Leaking laps in the waterproofing
- New membranes needing a check before handover
Landlords with a home close to Luton station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing, which affects testing.
Bituminous membranes
Bitumen roofs can often be tested electronically though the layers below matter.
