Electronic leak detection in Farncombe: what you get

Not every flat roof suits electronic testing. Certain membranes conduct electricity and some roofs do not have a suitable layer beneath the membrane. If your roof isn’t suitable, we’ll tell you at the start. Telling us what you know about the roof’s membrane and layers helps, including drawings, specifications or the roofer’s paperwork. It saves a wasted visit. If you are worried about holes around roof penetrations and repairs that haven’t stopped the leak, a survey will tell you what’s going on.

Outbuildings, garden rooms and garages in places like Farncombe often have flat roofs of their own. They’re easy to forget, but water through a garage roof can spoil whatever is stored inside. It is worth mentioning them when booking, so the visit can include them, along with the main flat roof. Smaller roofs use the same coverings as bigger ones, from felt to rubber and GRP, and age in the same way.

It is not only a list of defects. It explains what we found, why it matters and what we recommend.

Local flat roofs in Farncombe

With Loseley Park about 1.2 miles north, Farncombe sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area. Older houses across Surrey often have handmade clay tiles, and many have tile-hanging. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.

If you live in an older home near St John the Evangelist Church, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. Take a building like Farncombe Church of England Infant School: a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.

Farncombe is about 4 miles south-west of Guildford, in Surrey. We carry out electronic leak detection in Farncombe for houses, flats, blocks and commercial buildings, with a written report and photographs every time. Across Surrey, we cover Farncombe.

Common questions in Farncombe

Will you come out to Farncombe?

We do. A small place gets exactly the same survey as a big one.

Do you cover Farncombe?

Yes. We survey roofs across London and the South East, and Farncombe is part of that. Just call 07833 053749 or send us an email and let us know about the property.

Can you give me structural calculations?

No. We point out what can be seen, like sagging or deflection, but we’re not structural engineers and don’t carry out calculations. If we think you need an engineer, the report says so.

Can you inspect my roof with a drone?

Yes, where it is applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.

What’s the price of ELD?

Electronic leak detection is quoted for your roof, because the method depends on the roof. Size, build-up and access all affect the price. To get a quote, call 07833 053749 or use the contact form.

Is the repair part of the test?

No, the test finds the breaches and your roofer repairs them. The report gives your roofer the locations.

Can you survey at the weekend?

We carry out surveys on weekdays and at weekends. To find a day that suits you, ring 07833 053749 or email us.

What you can safely check yourself

During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can point to a blockage or a sagging run.

After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, which helps when we check the roof.

Why it is worth a survey now in Farncombe

Testing a new membrane before it’s covered is easier than tracing a leak later. Covered roofs are harder to test. With lower homes, common in places like Farncombe, there is little between a roof defect and the ceiling, so a small leak can mark a ceiling within a few storms. Catching the cause first saves redecorating as well.

The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.

Before and after the survey

A little preparation and a few simple habits help. Some pointers:

  • Don’t leave water getting in
  • Consider ELD before paving or planting goes on
  • Make sure trades protect the waterproofing
  • Keep a note of leaks after rain

Once repairs are made, the roof can be tested again if you want to check them, where the roof still suits the method.

Check contractors protect the waterproofing when they work up there. Check the roof after they’ve finished.

The survey, step by step

We photograph the roof as we go, so the report shows exactly what we saw. We take close-ups from wherever is safe. Most surveys take more time on a big roof than a small one, with the construction of the roof playing a part too. Being in a smaller place like Farncombe doesn’t change how the visit works: we look from the ground, from windows, from the loft and from the roof where it’s safe. Point out any stains, cracks or loose pieces you’ve spotted.

  1. You let us know 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. We test the roof and locate any breaches.
  5. You get a report with photos of each breach.

Preparing for the visit

  • Have any questions written down, so nothing gets missed
  • If you’re buying, check with the agent that we can get in
  • Move anything stored under the loft hatch

Advice

What this survey can’t tell you

Some things can’t be seen without opening up the roof, so a survey has limits:

  • Fixing the holes we find
  • Build-ups without a suitable layer below
  • Sections we can’t safely access

Not sure which survey suits your roof? You can ring 07833 053749 or use the contact form and we’ll tell you before you book. The full list of what we check.

Roofs we survey in Farncombe

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

Signs you need electronic leak detection in Farncombe

Holes in a membrane frequently come from feet, tools or debris. Some are too small to see, but still let water through.

A survey makes sense if you’ve noticed:

  • Waterproofing to test before it’s covered
  • Leaks through a flat roof with no obvious cause
  • Holes left by work on the roof
  • Failed seams and laps

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

Choosing a roof surveyor

  • Will the report include photos?
  • Whether the price includes VAT
  • Their report turnaround times
  • How they’ll see the roof: from the ground, the loft, the roof or by drone
