Electronic leak detection in Borehamwood

Liquid-applied waterproofing

Testing a liquid-applied roof depends on what’s beneath the coating.

Inverted and paved roofs

If the build-up rules out ELD, we will say so.

Electronic leak detection for homes and businesses in Borehamwood

Green roofs, ballasted roofs and roofs under paving are harder to test. The layers on top can limit the methods we can use and parts may need to be lifted. We talk this through before we quote. Drawings or details of the roof’s layers are useful because they show what’s under the surface. We will tell you if the roof can’t be tested. If you’ve noticed gaps at membrane joints and leaks through a flat roof with no obvious cause, we can find out what’s behind it.

In a town like Borehamwood, plenty of shops, schools and business units have flat roofs. They’re easy to forget until water comes through a ceiling tile. A survey, or electronic testing where the membrane suits it, shows what’s going on. Let us know who manages the building so access to the roof can be arranged.

Most points in the report come with a picture, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

What electronic leak detection doesn’t cover

A survey is a proper look at the flat roof membrane, but it can’t do everything. Its limits include:

  • Sections we cannot safely access
  • Water entering through details rather than the membrane
  • Repairing the breaches (that is for your roofer)

If you are not sure which survey you need, phone 07833 053749 or send us an email and we will give you a straight answer before booking. What a survey covers and doesn’t.

Roof types and parts we check

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

Electronic leak detection in Borehamwood: local notes

With Wyllyotts Manor about 4.3 miles north-east, Borehamwood sits in an area with a long building history. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Next to the main roofs there is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit.

If you look after a building such as St Teresa Catholic Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. If your home is one of the older ones in the streets near All Saints church, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear.

Borehamwood is about 5 miles east of Watford, in Hertfordshire. We carry out electronic leak detection in Borehamwood for houses, flats, blocks and commercial buildings, with a written report and photographs every time.

What happens on the day

We photograph the roof as we go, so the report shows exactly what we saw. We take close-ups from wherever is safe, including by drone where it’s applicable and the weather allows. A typical visit takes a time that depends on the size of the roof and how it’s built, and we’ll give you a guide when quoting. For a home in Borehamwood, the main things we need are a way into the loft, a route to the back garden and somewhere to park. If you won’t be there yourself, let us know who will let us in.

  1. We ask about the roof, its age, its membrane and where leaks appear inside.
  2. We check that the membrane and build-up suit electronic leak detection.
  3. The testing method is chosen to suit the membrane and build-up.
  4. We test the membrane and find where current is passing through it.
  5. The breaches are recorded with photos in a report for your roofer.

Before we arrive

  • For flats, make sure roof access has been agreed
  • Keep pets in another room
  • If it is not your property yet, arrange access through the agent

Getting a price

A quick phone call is normally the easiest start: call 07833 053749 or send us an email and we will ask a few questions about the roof. The price is agreed before a date is set.

FAQs for Borehamwood

Is Borehamwood in the area you cover?

Yes. We work right across London and South East England, and Borehamwood is part of that. You can ring 07833 053749 or use the contact form with the address and some details, and we’ll talk through which survey suits.

What do I need to do before a survey in Borehamwood?

Mostly, it is about access: the loft hatch, any locked gates and where to park in Borehamwood. Let us know about known leaks or past repairs as well.

Will I get photos?

Yes, every report has them. Each finding is shown in a picture where possible.

Do you need to get into the loft?

If there’s a loft and safe access to it, yes. From inside, the underside of the roof often shows damp, staining or daylight that can’t be seen from outside.

Which method do you use?

The roof decides the method. We will explain why when we quote.

Do you survey roofs on blocks of flats?

Yes, once access has been agreed. The roof of a block or converted house is frequently shared, so we need permission from whoever owns or manages the building. We inspect only the parts we’re allowed to reach.

Is this a RICS survey?

No. We check the roof, not the whole building, so it’s not a RICS Level 2 or Level 3 survey. Many buyers have both.

Why it is worth a survey now in Borehamwood

Opening up a roof to hunt for a leak is disruptive. ELD aims to locate the breach first, so the repair can be targeted. Once water reaches the loft insulation in a home in Borehamwood, it loses much of its value and is slow to dry. That’s an extra cost on top of the roof work itself.

Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before you book.

Why book us in Borehamwood

  • A sub-250g drone, flown with a CAA Flyer ID and Operator ID
  • Thermal imaging and drones used where they help
  • 20+ years’ experience
  • Plain-English reports with photos

How we price electronic leak detection

We confirm the exact price before booking. These are the things that affect it:

  • How tall the building is and how easy the roof is to see
  • Chimneys, valleys, parapets and other details
  • How many separate roofs there are, such as extensions, dormers and garages
  • The type of building, from a house to a block or an office

The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.

What to let us know when you get in touch

A little information up front helps. Please include:

  • Pictures from the garden or a window, if you have them
  • Your postcode, so we can check access and travel
  • What kind of property and roof it is
  • Where any leaks, stains or damp patches show inside

If you are buying, it’s useful to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just ring 07833 053749 or use the contact form when you are ready.

Common roof problems in Borehamwood

Other trades on the roof can puncture the waterproofing. Engineers fitting equipment, solar panels or aerials may leave damage behind.

Most people get in touch after spotting something like this:

  • Holes left by work on the roof
  • A flat roof leak that can’t be traced
  • Leaks showing away from the breach
  • New roofs to check before paving or planting

If you own a rental within reach of Elstree & Borehamwood station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

Before you book any roof surveyor
