Electronic leak detection in Halstead: what you get
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small electrical current that passes through the membrane only where there’s a breach. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. You get a report with photographs of each breach found. If you’ve noticed new membranes needing a check before handover and punctures from foot traffic or tools, we can find out what’s behind it, whatever the roof.
Flat roofs on exposed homes in small places like Halstead take more wind and rain, so edges, upstands and laps take a beating. Older felt roofs, frequently around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are typically the first part of a flat roof to go.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

What electronic leak detection looks like in Halstead
Historic houses such as Lullingstone Castle, about 3.2 miles north-east, show how far back building in the area around Halstead goes. 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 a listed home or one in a conservation area may need consent for changes of material. Handmade clay tiles, including Kent peg tiles hung on pegs through two holes, are typical of older Kent buildings. You’ll also find oast houses and timber-framed Wealden hall houses among the county’s older buildings. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
If you let a flat or house near Knockholt station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. The streets around a church such as St Margaret's Church are frequently among the oldest in a place, and if your home is one of the older ones nearby, the flat roofs on later extensions tend to wear out long before the main roof. For site and facilities teams at buildings such as Halstead Community Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Halstead is about 4 miles south of Orpington, in Kent. Whether the building in Halstead is a house, a flat or a commercial unit, we can survey the roof on a weekday or at the weekend. Halstead is one of the towns and villages in Kent we cover. Our London page covers surveys nearby.

DIY checks: what’s safe
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.
Your own check is a good start, but it is not a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground.
The survey, step by step
You don’t need to do much on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we will get on with the inspection. The survey itself takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Older rural homes like those around Halstead can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- The roof is assessed to see if electronic testing will work on it.
- 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.
Before the survey
- If you are buying, let the agent know when we’re coming
- Let us know where we can park nearby
- Gather any invoices or paperwork from past roof work
Book a survey

Your questions about electronic leak detection in Halstead
Do you carry out roof surveys in Halstead?
Yes, Halstead is one of the places we work. The survey and report are the same in Halstead as anywhere else, and visits run on weekdays and weekends.
Will you come out to Halstead?
Yes, smaller places are covered as well as towns. Our area covers London and the South East. Just mention lanes, gates or anything else about the route when booking.
Does someone need to be in?
Someone needs to let us in if we’re looking inside or in the loft. Access is agreed with you when you book.
What’s in the survey report?
It sets out what we found, why it matters and what we recommend, with photographs throughout. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
Do you look in the loft space?
Where it’s relevant to the survey and there is safe access, yes. Please clear anything stored under the hatch.
Can you give me structural calculations?
No. Visible signs such as deflection or sagging are recorded, but we don’t provide calculations or an engineer’s opinion. If one is needed, the report says so.
Does the weather affect the survey?
Light rain does not typically stop a survey, and it can even help show where water is getting in. Strong wind or heavy rain can stop drone flights and make roof access unsafe, so we’ll agree a new date if the weather is not suitable.
How the survey changes by roof type
Green and ballasted roofs
Some layers may need lifting for testing. We explain what’s needed when we quote.
Single-ply membranes
Many offices and units have single-ply roofs. Laps and fixings are where holes often appear.
Practical tips
You don’t need to be a roofer to help. What helps most:
- Use boards when working on the roof
- Don’t let outlets block
- Note where leaks show inside and when
- Find the breach before more patching
If water has been getting in, insulation under the membrane may be wet. That’s something to discuss with your roofer and other checks can help judge it.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
