Electronic leak detection in Swift's Green: what you get
There are different ELD methods. Low-voltage testing is normally done with the surface wet and high-voltage methods need the membrane dry and exposed. The right method depends on the membrane and the build-up of the roof, and we’ll explain our choice. If neither method suits your roof, we will tell you at the outset. Common reasons to book are leaks showing away from the breach and water coming in under a flat roof, across flat roof membranes, roof terraces and balconies and green roofs.
Some older homes in villages like Swift's Green are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

Different roofs, different checks
Bituminous membranes
Many flat roofs use bitumen-based membranes. The build-up decides which method will work.
EPDM rubber roofs
Certain rubber membranes are conductive which can limit electronic testing. We’ll say if the test will not work.
How the survey works
Every visit follows the same pattern: we listen to what’s been worrying you, inspect the roof from each safe vantage point, photograph what we find and record our findings for the written report. It typically takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Older rural homes like those around Swift's Green 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, and anything we can’t see is noted.
- We start by finding out what the roof is made of and where it leaks.
- The roof is assessed to see if electronic testing will work on it.
- We pick the low-voltage or high-voltage method that suits the roof.
- We test the membrane and find where current is passing through it.
- You get a report showing where each breach is, for your roofer to repair.
Before we arrive
- Mention any parking restrictions on your street
- Keep pets inside or away from the areas we’re looking at
- Point out any leaks or damp patches

Tips that help
A few practical points come up again and again on our surveys. They apply to most roofs:
- Test new membranes before covering them
- Share any drawings of the roof
- Make sure trades protect the waterproofing
- Record dates and spots where water appears
The report records each breach location with photos. Pass it to your roofer to repair the breach points.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.
Questions from Swift's Green
Is Swift's Green in the area you cover?
Yes. Our area covers London and the South East, and Swift's Green is part of that. You can ring 07833 053749 or use the contact form with the address and a few details, and we will talk through which survey suits.
Is my home in Swift's Green listed or in a conservation area?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Is it a structural engineer’s report?
No. We are experienced roof surveyors, and visible signs like sagging are noted, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
How long have you been surveying roofs?
We have more than 20 years’ experience and have completed over 5,000 surveys.
Are you insured?
We’re covered by professional indemnity and public liability insurance, for every survey we carry out.
Will you check the loft?
Yes, where the survey calls for it and there’s safe access. We look for staining, damp, daylight and signs of movement.
When does the report arrive?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. Each one is emailed.
Checking the roof from ground level
A DIY look is useful, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are frequently out of sight, and those are details a survey looks at closely.
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
Local flat roofs in Swift's Green
Handmade clay tiles, including Kent peg tiles hung on pegs through two holes, are typical of older Kent buildings. Kent’s older buildings take in oast houses and timber-framed Wealden hall houses as well. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops. There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material, so check with the council.
Landlords with a home close to Headcorn station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.

How we price electronic leak detection
We confirm the price for the job before you book. This is what makes a difference:
- Whether thermal imaging or a drone is needed
- Extensions, dormers and garages with roofs of their own
- Whether it is a home or a commercial building
- How tall the building is and how easy the roof is to see
The cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
