Electronic leak detection for homes and businesses in Sheet Hill
Our ELD testing covers flat roofs in Sheet Hill and the rest of London and South East England. A visit normally takes longer on a large roof than a small one, with the construction of the roof playing a part too. Electronic leak detection is quoted for your roof, because the method depends on the roof. The results come in a written report with photos. If you’ve noticed holes left by work on the roof and failed seams and laps, a survey will tell you what’s going on, on flat roof membranes, single-ply roofs and green roofs alike.
In a small place like Sheet Hill, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. 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 normally the first part of a flat roof to go.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

Flat roofs in Sheet Hill
Older houses across Kent frequently have handmade clay or peg tiles, and many have tile-hung walls. Kent’s older buildings take in oast houses and timber-framed Wealden hall houses as well. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. About 1.3 miles east lies Old Soar Manor, a reminder of how long the area around Sheet Hill 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 the council can say whether a home is in a conservation area.
For landlords with property near Borough Green & Wrotham station, 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 Plaxtol Primary School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

Should I look at the roof myself first?
Your own check is a good start, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight.
The one thing to avoid is getting up close. Roofs are fragile and slippery. That’s where a survey comes in, using safe viewpoints and a drone where it applies.
How it works
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. Then the inspection itself takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. In a small place like Sheet Hill, access is usually the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- We agree the area to be tested.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
How to prepare
- Jot down any questions you want answered
- Let us know about parking near the property
- Buyers: confirm access with the estate agent or seller

Advice
Sheet Hill questions
How do I find out if my home in Sheet Hill is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Is Sheet Hill in the area you cover?
Yes. We cover the whole of London and South East England, and Sheet Hill is part of that. You can phone 07833 053749 or send us an email with the address and a few details, and we will talk through which survey suits.
Can you survey at the weekend?
Surveys run on weekdays and at weekends. To find a day that suits you, phone 07833 053749 or drop us an email.
How does ELD work?
It uses an electrical current to find breaches in a flat roof membrane. The current only gets through where the membrane is breached so we can pinpoint it.
Can you survey a shared roof?
Yes, if whoever owns or manages the building agrees access. We look at the parts we are given access to, and the report makes that clear.
Do you use low-voltage or high-voltage testing?
The roof decides the method. You will know which method we plan to use before we start.
Do you climb onto every roof?
Only when it’s safe. Some roofs are too steep or fragile to walk on safely. We use safe viewpoints, the roof space and a drone where applicable.
What electronic leak detection doesn’t cover
A survey is a proper look at the flat roof membrane, but it can’t do everything. The main limits are:
- Roofs whose membrane or build-up is not suitable
- Areas we can’t reach or that cannot be tested
- Moisture spread under the membrane
Not sure which survey suits your roof? You can phone 07833 053749 or send us an email and we’ll tell you before you book. What a survey covers and does not.
What this survey covers
- Green roofs
- Flat roof membranes
- Liquid-applied waterproofing
- Single-ply roofs
- Commercial flat roofs
- Roof terraces and balconies
Signs you need electronic leak detection in Sheet Hill
A breach can be left during installation. ELD on a new roof can show holes before they cause leaks.
Signs worth acting on include:
- New roofs to check before paving or planting
- Patched roofs that still leak
- Water coming in under a flat roof
- Punctures from foot traffic or tools
For an older house near a landmark such as Plaxtol Church, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
Choosing a roof surveyor
- What exactly goes into their report
- When you will get the report
- Whether the loft is part of the inspection
- Is there a chance to talk the report through?
Tips that help
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Some tips:
- Let us know about the membrane and build-up if you know it
- Test new membranes before covering them
- Note where leaks show inside and when
- Don’t leave water getting in
You receive a report showing where each breach was found, with photos. Your roofer uses it to carry out repairs.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.
What affects the cost of electronic leak detection
Prices always include VAT. What changes the price is:
- Any need for thermal images or a drone flight
- The shape of the roof and its details
- House, block, shop or office
- How big the roof is
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
What to tell us when you get in touch
Getting the details right at the start saves time. It’s useful to include:
- What’s prompted the survey
- Photos of the roof, taken safely from the ground or a window
- Any deadline, like an exchange date
- The address and postcode of the property
Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, call 07833 053749 or drop us an email.
