Electronic leak detection for Kings Langley homes and businesses

Flat and commercial roofs around Kings Langley

Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. Historic houses like High Elms Manor, about 2.5 miles east, show how far back building in the area around Kings Langley goes. 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.

Take an older house close to Church of All Saints: the joins between later flat roofs and the old walls are where problems typically start. If you look after a building such as Kings Langley Primary School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.

About our electronic leak detection in Kings Langley

Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small electrical current that passes through the membrane only where there is a breach. That lets us locate holes that are too small to see, so your roofer can repair them. You get a written report with photos of each breach found. We survey flat roof membranes, roof terraces and balconies and commercial flat roofs, and common reasons people get in touch are stains far from any visible defect and leaks at pipes, outlets or fixings.

Around Kings Langley, many homes have a garden room, garage or outbuilding with a flat roof. They’re easy to forget, but water through a garage roof can spoil whatever is stored inside. It is worth mentioning them as you book, so the visit can include them. Smaller roofs use the same coverings as bigger ones, from felt to rubber and GRP, and age in the same way.

After the visit, you get a written report with photos, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

Kings Langley: your questions answered

Is my home in Kings Langley listed or in a conservation area?

Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.

Do you cover Kings Langley?

Yes, Kings Langley is one of the places we work. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.

How quickly is the report sent?

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.

Do you climb onto every roof?

Only where it’s safe to do so. We check everything that can safely be seen: from ground level, from windows, from inside the roof space, from the roof where it’s safe and by drone where applicable. Anything we can’t see is noted in the report.

How do I book a survey in Kings Langley?

Just call 07833 053749 or email us with the address. After a few questions, we confirm the price and fix a day.

How is ELD priced?

We quote electronic leak detection for each roof, as the method and time depend on the roof. The price depends on the roof’s size and build-up. For a quote, phone 07833 053749 or use the contact form.

Is this an asbestos survey?

No. We do not carry out asbestos surveys or testing. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them, and recommend a specialist asbestos surveyor checks them before they’re disturbed.

Should I look at the roof myself first?

Your own check is a good start, but it is not a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground.

If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.

Do you need electronic leak detection in Kings Langley?

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

Problems we come across frequently include:

  • Failed seams and laps
  • Patched roofs that still leak
  • Holes left by work on the roof
  • Breaches hidden under paving or planting

If you let a flat or house near Kings Langley station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

Before you book any roof surveyor

  • How soon the report will arrive
  • Their insurance cover
  • What happens after the report arrives
  • What the report includes, and whether it has photographs

What’s in a roof survey

For landlords and managing agents

For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait, which helps when budgeting.

Any of our surveys can be booked by landlords, agents and building managers in Kings Langley. To discuss a property or a block, phone 07833 053749 or email us.

Why get it checked now?

Water trapped under a membrane can soak insulation and decking. Finding the breach sooner limits that. On a bungalow or cottage around Kings Langley, the roof sits close to the rooms below, so water can show inside quickly once it gets past the covering. Finding the cause first saves a second job inside.

Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You will know the figure before booking.

How the survey works

The visit normally starts outside and finishes in the loft: outside views come first, then the roof space if there is safe access. In total, it takes more time on a big roof than a small one, with the construction of the roof playing a part too. Parking around Kings Langley is normally easier than in a town centre, but mention lanes, gates or long drives. Low roofs on bungalows can frequently be seen well from ground level, and the loft shows the rest, while taller roofs may need other vantage points or the drone where it applies.

  1. You tell us about the roof and where water is showing.
  2. We check whether the membrane and build-up suit ELD.
  3. The test method is chosen to suit the roof.
  4. The membrane is tested and breaches are found.
  5. You get a report with photos of each breach.

Before we arrive

  • Note where any stains or damp appear
  • Keep pets out of the way during the survey
  • If it is not your property yet, arrange access through the agent

Book a survey

Photos help, if you have them. Take them safely from ground level or a window; never climb up to get a better view. To send them or to book, call 07833 053749 or send us an email.

Advice

Roof by roof

Liquid-applied waterproofing

Liquid-applied coatings form a seamless layer but holes and thin areas can occur. Whether ELD works depends on the coating and build-up.

EPDM rubber roofs

Certain rubber membranes are conductive which can limit electronic testing. We will say if the test will not work.
