Electronic leak detection near Roydon

About our electronic leak detection in Roydon

Some flat roofs cannot be tested electronically. Certain membranes conduct electricity and some roofs don’t have a suitable layer beneath the membrane. We’ll say if ELD will not work on your roof at the start. Telling us what you know about the roof’s membrane and layers helps, like drawings or specifications. It saves a wasted visit. We are frequently asked to look into water coming in under a flat roof and breaches hidden under paving or planting, across single-ply roofs, roof terraces and balconies and liquid-applied waterproofing.

In a small place like Roydon, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Older felt roofs, often around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are typically the first part of a flat roof to go.

The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

DIY checks: what’s safe

A DIY look is useful, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground, and those are details a survey looks at closely.

After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.

Tips from our surveys

From years of surveys, a few habits stand out:

  • Limit access to the roof
  • Record dates and spots where water appears
  • Ask contractors to protect the membrane
  • Find the breach before more patching

If water has been getting in, insulation under the membrane may be wet. That is something to discuss with your roofer and other checks can help judge it.

Clear flat roof outlets regularly. Water that sits on the roof finds breaches faster.

Common questions in Roydon

Is Roydon within the area you cover?

Yes, smaller places are covered as well as towns. We survey roofs across London and the South East. Just mention lanes, gates or anything else about the route when booking.

Does a conservation area affect roof work in Roydon?

Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.

Can you survey in bad weather?

Some surveys depend on the weather more than others. Drone flights need calm, dry weather, and thermal imaging works best after a sunny day, with a dry roof and little wind. We will rearrange with you if the weather isn’t right.

Is my roof suitable for ELD?

It depends on the membrane and the build-up. Let us know what you know about the roof and we will check whether ELD will work.

What does electronic leak detection do?

ELD passes a small electrical current across the roof to locate holes in the membrane. The current only gets through where the membrane is breached, which shows us where the hole is.

How many surveys have you done?

We have more than 20 years’ experience and have completed over 5,000 surveys.

Which days do you carry out surveys?

Visits run seven days a week in the daytime. Let us know your preferred days as you book.

When to book a survey in Roydon

Roofs covered with paving, ballast or planting hide the membrane. ELD can work on some covered roofs though it depends on the layers.

It’s worth booking a survey if you’ve seen:

  • New membranes needing a check before handover
  • Damage from equipment installers
  • Leaks through a flat roof with no obvious cause
  • Repairs that haven’t stopped the leak

If you let a flat or house near Roydon station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

What to check before booking

  • Whether they hold professional indemnity and public liability insurance
  • Is there a chance to talk the report through?
  • Which parts of the roof they’ll actually see
  • What experience they bring

What a roof survey includes

How we price electronic leak detection

Not every roof costs the same to survey, and it comes down to:

  • The size of the roof
  • Chimneys, valleys, parapets and other details
  • Building height and the viewpoints available
  • Extra roofs, like extensions, dormers or garages

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.

Helping us price your survey

Before you get in touch, it helps to have:

  • Where the property is, with the postcode
  • The type of building and roof, such as pitched or flat
  • Pictures of the roof from a safe spot, if you have them
  • Any stains, drips or damp patches you’ve seen indoors

Every survey is priced before it’s booked, so you know where you stand. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, phone 07833 053749 or use the contact form.

Landlord and commercial surveys in Roydon

If you own several properties, you can book surveys for several addresses. To discuss a number of properties, call 07833 053749 or drop us an email.

Businesses and commercial landlords can book us too. Bigger roofs take more time, and they’re priced for the size.

Flat and commercial roofs around Roydon

Older buildings may be listed or sit in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. In either case, a change of roofing material may need consent. Clay tiles and timber weatherboarding mark out many of the older buildings in Essex, with post-war and more recent estates making up much of the newer housing. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.

If you look after a building such as Roydon Primary School, a large flat roof with lots of outlets and rooflights has many places where a membrane can fail. Take an older house close to St Peter's Church: the joins between later flat roofs and the old walls are where problems normally start.

What happens on the day

The visit usually starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. In total, it takes a time that depends on the membrane area and the build-up, and we’ll give you a guide when quoting. In a hamlet or village like Roydon, a postcode does not always lead to the right gate, so a few directions are welcome. After that, the survey runs as it would anywhere.

  1. We start by finding out what the roof is made of and where it leaks.
  2. We check that the membrane and build-up suit electronic leak detection.
  3. The method depends on the membrane and what sits above and below it.
  4. Testing runs across the roof to locate breaches in the membrane.
  5. You get a report showing where each breach is, for your roofer to repair.

Preparing for the visit

  • Keep pets in another room
  • Mention any parking restrictions on your street
  • Move anything stored under the loft hatch
