How electronic leak detection works in South Darenth
Electronic testing locates holes in the waterproofing but not every way water gets in. Water coming through walls, copings, rooflights or plumbing will not 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. Our report keeps that distinction clear. You’ll also know what to check next. If you’ve noticed leaks showing away from the breach and leaks at pipes, outlets or fixings, we can find out what’s behind it, on commercial flat roofs, green roofs and single-ply roofs alike.
In a small place like South Darenth, a flat roof can stand in the open, so edges, upstands and laps take a beating. Older felt roofs, frequently around 15–20 years in life, 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.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

FAQs for South Darenth
Does a conservation area affect roof work in South Darenth?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Do you cover smaller places like South Darenth?
Yes, smaller places are covered as well as towns. We cover the whole of London and South East England. Let us know about access, parking and anything unusual about getting there when booking.
Can every flat roof be tested?
Not every roof is suitable. Certain membranes are conductive and some roofs lack the layer the test needs. If your roof won’t work, we will say so before testing.
Are you structural engineers?
No. We note visible signs such as sagging or deflection, but we do not carry out calculations or give an engineer’s opinion. If we think you need an engineer, the report says so.
Will I get photos?
Yes. Photographs are part of every report, so you can see exactly what each finding refers to.
How long have you been surveying roofs?
We’ve completed more than 5,000 surveys, over more than 20 years, and 98% of clients are satisfied.
Will you walk on the roof?
Only when it’s safe. Most of what we need can be seen from safe viewpoints, the loft and, where it applies, a drone.
Rented homes, blocks and businesses
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan.
Roof problems in a rented home affect tenants as well as the building. A survey shows what needs attention, so you can plan the work with less disruption.
Practical tips
You don’t need to be a roofer to help. Here’s what helps most:
- Don’t keep patching the same spot
- Ask contractors to protect the membrane
- Stay off the flat roof unless needed
- Check new waterproofing before handover
File the report with your roof paperwork. It is a dated record of the membrane’s condition.
ELD before paving, ballast or planting goes on is worth considering. It’s easier to find holes before more layers are added.

What a survey costs
To price your survey, we look at:
- How many separate roofs there are, such as extensions, dormers and garages
- The height of the building and how the roof can safely be seen
- The size of the roof
- How complicated the roof is, with its valleys, chimneys and parapets
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You’ll know the figure before booking.
What we need to know
When you call or email, these details help:
- Access details, such as a loft hatch or a shared roof
- When you need the report by
- The type of building and roof, like pitched or flat
- Your postcode, so we can check access and travel
To arrange a survey, phone 07833 053749 or email us and tell us the address and what’s prompted the survey. We’ll confirm the price before booking.
Should I look at the roof myself first?
Look up at the roof after a storm, from the ground: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.
Why get it checked now?
Opening up a roof to hunt for a leak is disruptive. Electronic testing finds the hole first, so the repair can be targeted. Where a roof is exposed, as many are in small places like South Darenth, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.

Electronic leak detection in South Darenth: local notes
Older houses across Kent frequently have handmade clay or peg tiles, and many have tile-hung walls. Oast houses and timber-framed Wealden hall houses are part of the county’s older buildings too. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Historic houses such as Lullingstone Castle, about 3.9 miles south-west, show how far back building in the area around South Darenth goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
If you look after a building such as Horton Kirby Church of England Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If you run a business near Bluewater, the flat roofs over shops and commercial units are worth checking before a leak, not after. For landlords with property near Farningham Road station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

What happens on the day
The visit has one job: 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 normally takes as long as needed for the roof’s area and construction, which we’ll explain when we quote. Older roofs in small places like South Darenth can have low, tight loft spaces, so let us know about the loft hatch and any ladder. We only go where it is safe.
- We start with what you know about the roof and the leak.
