Electronic leak detection near Great Notley

Electronic leak detection in Great Notley: what you get

ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small electrical current which can only get through the membrane at a breach. That lets us locate holes that are too small to see, so your roofer can repair them. The results come in a report with photos. Typical surveys look at failed seams and laps and repairs that haven’t stopped the leak, across roof terraces and balconies, liquid-applied waterproofing and commercial flat roofs.

In a smaller place like Great Notley, some flat roofs sit in the open, so wind catches loose edges and trims. Sun on a flat roof also ages felt and bitumen. Splits, blisters and lifting edges are what to look out for, along with water that sits after rain. Standing water that lingers for days after rain is another sign worth watching for.

We write the report in plain English, so you do not need to be a roofer to follow it. Photos show what each point refers to.

What we’re asked to look at in Great Notley

New membranes can have defects from installation. ELD on a new roof can show holes before they cause leaks.

Common reasons to book include:

  • Leaks through a covered membrane
  • Stains far from any visible defect
  • Leaks at pipes, outlets or fixings
  • Waterproofing to test before it is covered

For landlords with property near Braintree station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

Before you book any roof surveyor

  • Their insurance cover
  • What happens after the report arrives
  • Do they have a CAA Flyer ID and Operator ID for drone work?
  • Will the report include photos?

What to expect from a roof survey

The survey, step by step

Safety comes first on every visit. We inspect what can be seen safely, and if part of the roof can’t be seen, the report says so. Most visits take longer on a large roof than a small one, with the construction of the roof playing a part too. For a survey in Great Notley, we agree the time, the access and parking before the day. Visits can be on weekdays, Saturdays or Sundays. If there are outbuildings or garages you want looked at, mention them.

  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. You receive the results to pass to your roofer.

Before the survey

  • Make a note of anything you’d like us to look at
  • Check we can get to the back of the property
  • Point out any leaks or damp patches

How to book

Getting a price is simple: just phone 07833 053749 or send us an email, tell us about the property and we’ll explain which survey suits. We confirm the price before anything is booked.

Great Notley: your questions answered

Will you come out to Great Notley?

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

Do you cover Great Notley?

Yes, Great Notley is within the area we cover. Our area covers London and the South East. Just phone 07833 053749 or use the contact form and let us know about the property, and we’ll talk through which survey suits.

Does ELD work under paving or planting?

It can be possible, depending on the roof. What sits on the membrane affects the method, so we check the build-up first.

Does the report include photographs?

Yes. Photographs are taken throughout the survey, and the report uses them to show each finding alongside our recommendations.

Do you look in the roof space?

Where it’s relevant to the survey and there is safe access, yes. A clear path to the hatch helps, and if the loft cannot be reached safely, the report says so.

How long does electronic leak detection take?

Testing usually takes a time that depends on the roof’s area and construction, which we’ll explain when we quote.

Is it a structural engineer’s report?

No. We note visible signs like sagging or deflection, but we do not carry out calculations or give an engineer’s opinion. If we think you need an engineer, the report says so.

Can I check my roof myself?

It’s useful to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us as you book, as it helps us focus the survey.

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

What we look for on each type of roof

Liquid-applied waterproofing

What lies under a liquid coating decides if ELD will work.

EPDM rubber roofs

Some EPDM membranes conduct electricity, which can rule out some methods. We’ll say if the test will not work.

Before and after the survey

Most of what helps is simple and safe from ground level. Our suggestions:

  • Limit access to the roof
  • Avoid repeated repairs without finding the cause
  • Test new membranes before covering them
  • Use boards when working on the roof

Where the evidence points to walls, copings or rooflights, we’ll note it, with a suggestion of what to check next.

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

Flat and commercial roofs around Great Notley

Older buildings in Essex often have clay tiles and weatherboarding, with post-war and more recent estates making up much of the newer housing. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. 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.

For an older house near a landmark such as The Church in Great Notley, flat-roofed rear additions and dormers added over the years are worth checking. If you look after a building such as White Court School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
