Electronic leak detection for homes and businesses in Stonehill Green
Roofs covered with paving, ballast or planting need more thought. The layers on top can limit the methods we can use, and some may need lifting. We’ll discuss it with you when we quote. Any details of the build-up help, as they show what lies beneath the surface. We’ll tell you if the roof cannot be tested. If you’ve noticed damage from equipment installers and leaks through a flat roof with no obvious cause, a survey will tell you what’s going on, whatever the roof.
Somewhere as small as Stonehill Green, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them when you book.
The report records the flat roof membrane as we found it on the day. It’s useful right away, and a good reference for later, for example when you want to check whether anything has changed.

What we’re asked to look at in Stonehill Green
Joints and laps in a membrane can fail over time. Small openings at laps can leak long before anyone notices.
Common reasons to book include:
- Leaks at pipes, outlets or fixings
- Water coming in under a flat roof
- Punctures from foot traffic or tools
- Leaking laps in the waterproofing
If your house is among the older ones in the streets near St Peter, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
What to check before booking
- What happens after the report arrives
- Their track record with similar roofs
- What they will not be able to tell you
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
Practical tips
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Act on new leaks promptly
- Keep a note of leaks after rain
- Check new waterproofing before handover
- Share any drawings of the roof
If anything in the report isn’t clear, ask us. We can talk you through the findings.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.
Flat and commercial roofs around Stonehill Green
The wider area around Stonehill Green has a long history of building, with Hall Place and Gardens about 2.4 miles north. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material. Across Kent, older roofs are frequently 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 on extensions, dormers, garages and business units are found alongside them almost everywhere.
Landlords with a home close to Swanley station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round. Anyone responsible for a site like Hextable School will know that a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.

Stonehill Green: your questions answered
Is Stonehill Green within the area you cover?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Do you cover Stonehill Green?
Yes, Stonehill Green is one of the places we work. The survey and report are the same in Stonehill Green as anywhere else.
Will you repair the leak?
No. We test the membrane and report. The report shows where each breach is for your roofer to repair.
Is it a structural engineer’s report?
No. Visible signs like deflection or sagging are recorded, but we don’t provide calculations or an engineer’s opinion. If one is needed, the report says so.
How much time does ELD need?
Testing normally takes longer on a large roof than a small one, with the construction of the roof playing a part too.
Does electronic leak detection work on all membranes?
It depends on the membrane and the build-up. Let us know what you know about the roof and we will confirm suitability.
Does the report include photos?
Yes. Photos are taken throughout the survey, and the report uses them to show each finding.
What we cannot see
Every survey has limits, and it’s better to know them up front. Bear these in mind:
- Sections we can’t safely access
- Moisture spread under the membrane
- Roofs whose membrane or build-up is not suitable

How it works
Expect us to ask a few questions before we start, like when any problem began and what work has been done before. Then the inspection itself takes as long as needed for the membrane area and the build-up, which we’ll explain when we quote. Somewhere like Stonehill Green needs a little journey planning: let us know about lanes, gates and parking. The roof is looked at from the ground, from windows, from the loft where there is safe access and from the roof where it is safe.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Before the survey
- Let us know where we can park nearby
- Leave side gates unlocked
- Agree roof access with the managing agent if it’s shared

Advice
Should I look at the roof myself first?
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.
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
What we look for on each type of roof
Liquid-applied waterproofing
What lies under a liquid coating decides if ELD will work.
Inverted and paved roofs
Paving and terraces cover the membrane. Whether it can be tested depends on the build-up.
