Electronic leak detection for Knave's Ash homes and businesses

Electronic leak detection for homes and businesses in Knave's Ash

You get a report showing the location of each breach, with photos. Your roofer can then repair those points instead of hunting for the leak. We don’t estimate repair costs, so your roofer prices the work. A retest after repairs can check the work, where the roof still suits the method. Results come in a written report with photos. If you are worried about water coming in under a flat roof and stains far from any visible defect, a survey will tell you what’s going on, on single-ply roofs, flat roof membranes and liquid-applied waterproofing alike.

Somewhere as small as Knave's Ash, 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.

Nothing in the report is left vague: if work is needed, the report says so clearly, and where it can wait, that is said too.

Your questions about electronic leak detection in Knave's Ash

Is my home in Knave's Ash listed or in a conservation area?

We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.

Does being near the coast affect roofs in Knave's Ash?

Near the coast, roofs face more wind and more salt than further inland. Salt is hard on nails, clips and metal flashings, while strong wind lifts anything already loose.

Can you find leaks on a covered flat roof?

In some cases. The layers on top and the build-up below decide it, and some may need lifting. We talk this through first.

Will you walk on the 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.

Can you survey a shared roof?

Yes. A shared roof needs access agreed first, with the freeholder or managing agent. Mention it when you get in touch and we will explain what’s needed.

What is electronic leak detection?

It uses an electrical current to find breaches in a flat roof membrane. A breach lets the current through, which shows us where the hole is.

Do you cover Knave's Ash?

Yes. Knave's Ash is part of the area we cover, and the service is the same as everywhere else we work.

What we do, step by step

We check the roof from outside and, where it’s relevant and there’s safe access, from inside the loft space too. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. All in, the survey typically takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Somewhere like Knave's Ash needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. On the day, we inspect what can safely be seen, inside and out.

  1. First, you let us know about the roof build-up and where water is showing.
  2. The roof is assessed to see if electronic testing will work on it.
  3. The method depends on the membrane and what sits above and below it.
  4. The roof is tested and any breaches are located.
  5. You get a report showing where each breach is, for your roofer to repair.

How to prepare

  • Clear the way to the loft hatch
  • Gather any invoices or paperwork from past roof work
  • Mention any parking restrictions on your street

Roof by roof

Bituminous membranes

Bitumen roofs can frequently be tested electronically though the layers below matter.

EPDM rubber roofs

Some EPDM membranes conduct electricity which can limit electronic testing. We’ll tell you if yours is not suitable.

When to book a survey in Knave's Ash

Water travels under flat roof membranes. The leak may show some distance from where water gets in, so tracing it by eye is difficult.

People usually book a survey after spotting something like this:

  • New membranes needing a check before handover
  • Patched roofs that still leak
  • Breaches hidden under paving or planting
  • Breaches around outlets and penetrations

For an older house near a landmark such as Church of the Holy Cross, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

Before you book any roof surveyor

  • Whether you can ask questions once you have the report
  • How they plan to inspect the roof safely
  • What they will not be able to tell you
  • Whether the loft is part of the inspection

What a roof survey includes

What electronic leak detection doesn’t cover

Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:

  • Roofs whose membrane or build-up isn’t suitable
  • Carrying out the repair work
  • Leaks from plumbing or windows

If you are not sure which survey you need, call 07833 053749 or drop us an email and we will give you a straight answer before you book. What our survey covers.

Roofs we survey in Knave's Ash

  • Flat roof membranes
  • Liquid-applied waterproofing
  • Green roofs
  • Roof terraces and balconies
  • Commercial flat roofs
  • Single-ply roofs

What happens if roof problems are left?

ELD before paving, ballast or planting goes on is simpler. Covered roofs are harder to test. In a place like Knave's Ash, a barn or garage roof left to fail puts whatever is inside at risk. A quick look before winter can save a lot.

Electronic leak detection in Knave's Ash: local notes

Knave's Ash is within about 3 miles of the coast, and being near the sea means more wind and salt than a roof inland would face. Salt in the air is hard on metal flashings and fixings, and wind catches any loose edge on a flat roof. Many older homes in Kent have handmade clay tiles, including Kent peg tiles held by pegs through two holes, and tile-hanging on their upper walls. Kent’s older buildings take in oast houses and timber-framed Wealden hall houses as well. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.

Take a building like Hoath Primary School: a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail. If you let a flat or house near Herne Bay station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

Knave's Ash is about 2 miles south of Herne Bay, in Kent. Wherever you are in Knave's Ash, we can come and survey your property. Knave's Ash is one of the places in Kent we cover for electronic leak detection.

Practical tips

Here are a few things we’d tell any owner:

  • Keep a note of leaks after rain
  • Stay off the flat roof unless needed
  • Consider ELD before paving or planting goes on
  • Do not let outlets block

Wet insulation may need attention after a leak. That is something to discuss with your roofer and other checks can help judge it.

Keep outlets and gutters on flat roofs clear. Standing water puts more pressure on any weak point.
