How electronic leak detection works in Hazelwood
Our ELD report shows where each breach was found, with photos. Your roofer can then repair those points instead of hunting for the leak. Repair costs are not part of the report, so your roofer prices the work. Testing again after repairs can confirm the breaches have been dealt with if the build-up allows. You get a written report with photos. We survey flat roof membranes, roof terraces and balconies and single-ply roofs, and people most often book us about punctures from foot traffic or tools and damp inside with no sign on the roof.
Some older homes in villages like Hazelwood 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. Listed building consent is needed for changes that affect a listed building’s special interest.
Most points in the report come with a picture, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

Before and after the survey
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Limit access to the roof
- Check new waterproofing before handover
- Ask contractors to protect the membrane
- Share any drawings of the roof
Questions about the results are welcome. We can talk you through the findings.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.

Buyers’ agents can book surveys on behalf of their clients. Reports are emailed, so they’re easy to pass on, photographs included.
Letting agents can arrange access with tenants. Surveys run seven days a week, which helps when tenants work during the week.
What happens if roof problems are left?
Repairs in the wrong place leave the leak in place. Testing shows where the membrane is actually breached. Around Hazelwood, older homes frequently have old roof timbers, where water from a failed roof can cause rot if it’s left.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before you book.

How the survey changes by roof type
Liquid-applied waterproofing
Liquid waterproofing has no laps, but can still have thin spots or holes. Suitability for ELD depends on the system.
Single-ply membranes
Some single-ply membranes suit electronic testing well, depending on the type and build-up.
Flat and commercial roofs around Hazelwood
The wider area around Hazelwood has a long history of building, with Down House about 1 mile west. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, 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. 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.
For site and facilities teams at buildings like Downe Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. If you live in an older home near St Mary's Church, the joins between later flat roofs and the old walls are where problems normally start. If you own a rental within reach of Chelsfield station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

What we do, step by step
When we arrive, we start by asking what you’ve noticed and what you need to know. After that, we look at everything we can see safely, from the ground, from windows, in the roof space and by drone where applicable. Most surveys take more time on a big roof than a small one, with the construction of the roof playing a part too. Around Hazelwood, older homes can have small or awkward roof spaces, so it helps to know whether there is a loft hatch and how easy it is to reach. Only areas that can be reached safely are inspected.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.

Advice
Your questions about electronic leak detection in Hazelwood
Is Hazelwood in the area you cover?

Is Hazelwood within the area you cover?
Yes, Hazelwood is covered. We work right across London and the South East, from towns to the smallest villages. Longer journeys are simply planned in advance.
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.

Surveys run on any day of the week. To arrange a date, phone 07833 053749 or use the contact form.
How fast do I get the report?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline when booking.
Can every flat roof be tested?
It depends on the membrane and the build-up. Let us know what you know about the roof and we will check whether ELD will work.
Will I get photos?
Yes. The report includes photos of what we found.
What this survey can’t tell you
Without opening up the roof, some things stay hidden, and that sets some limits:
- Sections we can’t safely access
- Water entering through details rather than the membrane
- Fixing the holes we find
