Electronic leak detection for homes and businesses in Barnes Cray
Some flat roofs can’t be tested electronically. Certain membranes conduct electricity, and some build-ups lack the layer the test needs below the membrane. If your roof isn’t suitable, we will tell you at the start. Telling us what you know about the roof’s membrane and layers helps, such as drawings or specifications. It saves a wasted visit. We’re frequently asked to look into a flat roof leak that can’t be traced and waterproofing to test before it’s covered, across liquid-applied waterproofing, commercial flat roofs and single-ply roofs.
Flat roofs in smaller places like Barnes Cray can be more exposed, particularly where nothing shelters them, where wind can catch loose edges and trims. Felt and bitumen also age in strong sun. Splits, blisters and lifting edges are what to look out for, along with water that sits after rain. Standing water that lingers for days after rain is another sign worth watching for.
The report is written in plain words, so it makes sense without any roofing background. Each point is backed by a photograph where possible, and recommendations are put with the most urgent first where relevant.

What we look for on each type of roof
Single-ply membranes
Many offices and units have single-ply roofs. Laps and fixings are where holes often appear.
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing, which affects testing.
Local flat roofs in Barnes Cray
Across Kent, older roofs are often handmade clay or peg tiles, and tile-hanging on upper walls is a familiar sight. You’ll also find oast houses and timber-framed Wealden hall houses among the county’s older buildings. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. About 1.7 miles south-west lies Hall Place and Gardens, a reminder of how long the area around Barnes Cray has been built on. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first.
For site and facilities teams at buildings such as Haberdashers' Aske's Crayford Academy, a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail. If you let a flat or house near Slade Green station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. If you run a business near Broadway Shopping Centre, outlets and upstands on commercial flat roofs are the places to check before trouble starts.

Barnes Cray: your questions answered
How do I find out if my home in Barnes Cray is listed?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Do you cover smaller places like Barnes Cray?
Yes, we do. We survey roofs across London and South East England, from towns to the smallest villages. The journey is planned ahead, so it helps to know about access.
Can every flat roof be tested?
That depends on the roof’s membrane and layers. Share any details you have and we will check whether ELD will work.
Will you walk on the roof?
Only when it’s safe. Safe viewpoints, the loft space and a drone where applicable cover most of what’s needed.
Do you survey on Saturdays and Sundays?
We carry out surveys on weekdays and at weekends. To find a day that suits you, ring 07833 053749 or email us.
Can you test a green or ballasted roof?
On some roofs, yes. Covered roofs limit the methods we can use so we check the roof first.
Is it a structural engineer’s report?
No. Our survey is not a structural engineer’s report. If we see signs that need an engineer’s opinion, we will recommend one.

What happens on the day
You don’t need to do much on the day. Show us any stains, drips or problem areas you know about, and we’ll take it from there. The survey itself takes longer on a large roof than a small one, with the construction of the roof playing a part too. With a bit of garden around a house, as there frequently is around Barnes Cray, the roof can be viewed from several angles. Mention any side of the property we can’t get to. Inside, the loft is checked where it can be reached safely.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Before we arrive
- Unlock side gates and any roof access doors
- Let us know about parking before the day
- If it is not your property yet, arrange access through the agent

Advice
Before and after the survey
A little preparation and a few simple habits help, both for the survey and for the roof itself. Some pointers:
- Test new membranes before covering them
- Do not let outlets block
- Find the breach before more patching
- Check trades protect the waterproofing
Questions about the results are welcome. We’ll explain what was found and what it means.
Check contractors protect the waterproofing when fitting equipment. Have the roof looked at after other work.
Should I look at the roof myself first?
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. Do not go up yourself.
Keep a simple record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry and it will help the survey.
Rented homes, blocks and businesses
Landlords and letting agents in Barnes Cray book surveys as well as householders. The report gives you a dated record of the flat roof membrane, with photos.
Letting agents can arrange access with tenants. Surveys run on weekdays and at weekends, which helps when tenants work during the week.
Why it is worth a survey now in Barnes Cray
Patching where you think the leak is frequently misses it. ELD shows the actual breach points. In an older home around Barnes Cray, water from a roof defect can get into timber and plaster, and that’s a much bigger job than the original defect.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before booking.
