Electronic leak detection in Underriver

Not every flat roof suits electronic testing. Some membranes conduct electricity themselves and some roofs don’t have a suitable layer beneath the membrane. If your roof isn’t suitable, we’ll tell you before any testing. Telling us what you know about the roof’s membrane and layers helps, including drawings, specifications or the roofer’s paperwork. It avoids arranging a test that can’t give results. We survey single-ply roofs, green roofs and roof terraces and balconies, and the problems we’re asked to look at most are patched roofs that still leak and breaches hidden under paving or planting.

Some older homes in villages like Underriver 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. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.

Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

Common questions in Underriver

Will you come out to Underriver?

Yes, Underriver is on our map. A small place gets exactly the same survey as a big one.

Does a conservation area affect roof work in Underriver?

The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.

Do I have to be there for the survey?

If the survey includes the loft or the inside of the building, someone needs to let us in. We will talk about access when you book.

How do I book a survey in Underriver?

To book, ring 07833 053749 or use the contact form and tell us the address and what you’d like to know. We will confirm the price and find a day that suits.

How much time does ELD need?

It depends on the size of the roof and its build-up. We’ll give you an idea when we quote.

What happens after the survey?

You will receive the report by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.

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.

What we are asked to look at in Underriver

Flat roof membranes can be punctured by foot traffic, dropped tools or debris. Some are too small to see, but still let water through.

Problems we come across often include:

  • New roofs to check before paving or planting
  • Gaps at membrane joints
  • Patched roofs that still leak
  • Leaks under green or ballasted roofs

Landlords with a home close to Hildenborough station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

What a good roof survey covers

  • Carrying out the repair work
  • Parts of the roof covered by fixed equipment
  • How wet the insulation is

If you are not sure which survey you need, call 07833 053749 or send us an email and we’ll give you a straight answer. What our survey covers.

What this survey covers

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

Why it’s worth a survey now in Underriver

Patching where you think the leak is often misses it. ELD shows the actual breach points. Around Underriver, older homes often have old roof timbers, and water through a failed covering can rot timber if it is left.

The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.

Electronic leak detection around Underriver

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. Oast houses and timber-framed Wealden hall houses are part of the county’s older buildings too. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops. Knole House, about 1.6 miles north-west, is one of the historic houses in the wider area around Underriver. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.

Anyone responsible for a site like Sevenoaks Preparatory School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. For an older house near a landmark like Church of St Margaret, the joins between later flat roofs and the old walls are where problems usually start.

The survey, step by step

We work from the outside in: outside views come first, then the loft space if there’s safe access. In total, it takes as long as needed for the membrane area and the build-up, which we set out in the quote. Somewhere as small as Underriver, access is often the only tricky part. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.

  1. First, we confirm which roof areas are included.
  2. We get the roof ready for testing.
  3. Testing runs across the agreed area.
  4. We mark the breach locations in our records.
  5. The report is sent for your roofer to act on.

Before the survey

  • Move anything stored under the loft hatch
  • Buyers: confirm access with the estate agent or seller
  • Jot down any questions you want answered

Arrange a survey

Booking is simple: just ring 07833 053749 or email us and give us a few details about the property and we will suggest the right survey. We confirm the price before anything is booked.
