Electronic leak detection in Great Berry
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small 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 photos of each breach found. If you are worried about damage from equipment installers and gaps at membrane joints, we can find out what’s behind it, on commercial flat roofs, roof terraces and balconies and single-ply roofs alike.
In a smaller place like Great Berry, some flat roofs sit in the open, where wind can catch loose edges and trims. Sun on a flat roof also ages felt and bitumen. The signs are splits, blisters and edges coming away, along with water that sits after rain. A flat roof that still holds water days after rain is also worth a closer look.
We write the report in plain English, so it makes sense without any roofing background. Each point is backed by a photo where possible, and recommendations are put with the most urgent first where relevant.

Roof by roof
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Testing may still be possible, depending on the build-up.
Single-ply membranes
Single-ply can be punctured by tools or fixings. ELD can locate them.

What else we do in Great Berry
Rented homes, blocks and businesses
We also survey roofs for businesses and commercial landlords, from shops and offices to industrial units. Larger roofs take longer, and they’re priced for the size.
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. Recommendations are set out by urgency where it matters, which helps with budgets and planning.
How it works
After the inspection, everything we found is written up in a report with photographs. As for time on site, it normally takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. With a bit of garden around a house, as there frequently is around Great Berry, the roof can be viewed from several angles. Let us know if any side is fenced off or hard to reach. Inside, the loft is looked at where it can be reached safely.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Getting ready for the survey
- If it is not your property yet, arrange access through the agent
- Move anything stored under the loft hatch
- Unlock side gates and any roof access doors
Booking a survey
We survey roofs on weekdays and at weekends. To arrange a day that suits you, ring 07833 053749 or email us.
Advice
Useful tips for Great Berry property owners
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Keep outlets clear of debris
- Note where leaks show inside and when
- Stay off the flat roof unless needed
- Do not keep patching the same spot
If anything in the report is not clear, ask us. We will explain what was found and what it means.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
When you need someone else
Every survey has limits, and it is better to know them up front. Bear these in mind:
- Sections we cannot safely access
- Build-ups without a suitable layer below
- Carrying out the repair work

Your questions about electronic leak detection in Great Berry
How do I find out if my home in Great Berry 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.
Do you cover smaller places like Great Berry?
Yes, smaller places are covered as well as towns. We survey roofs across London and South East England. Just mention lanes, gates or anything else about the route when you book.
How is ELD priced?
We quote electronic leak detection for each roof, as the method and time depend on the roof. Size, build-up and access all affect the price. To get a quote, call 07833 053749 or use the contact form.
Do I have to be there for the survey?
That depends on the survey. Inside the building and in the loft, we need someone to let us in, while outside access can be discussed when you book.
Can you test a green or ballasted roof?
In some cases. It depends on the build-up and the layers above the membrane, and some may need lifting. We talk this through first.
Will you check the loft?
If the survey needs it and the loft space can be reached safely, yes. A clear path to the hatch helps, and if the loft cannot be reached safely, the report says so.
Can you survey at the weekend?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Just say which days work for you.
Electronic leak detection around Great Berry
Great Berry lies within about 5 miles of the sea, so there is more wind and more salt in the air than further inland. Wind can catch loose edges and trims on a flat roof, and salt air is hard on metal trims, flashings and fixings. Weatherboarded walls and clay tile roofs are typical of older Essex buildings, alongside a good many post-war and newer estates. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
The streets around a church like St John are often among the oldest in a place, and if yours is one of the older homes nearby, flat-roofed rear additions and dormers added over the years are worth checking. For site and facilities teams at buildings such as Great Berry Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

When to book a survey in Great Berry
Water travels under flat roof membranes. The stain inside can be far from the hole, so tracing it by eye is difficult.
Typical things we are asked to look at include:
- Breaches around outlets and penetrations
- Damp inside with no sign on the roof
- Leaks through a covered membrane
- Gaps at membrane joints
If you own a rental within reach of Laindon station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Questions to ask before you book
- Whether the loft space is looked at, where there is one
- How much experience they have with roofs like yours
- What follow-up you get after the report
- Whether you get a written report with photos
