Electronic leak detection in Widford

Electronic leak detection around Widford

Much Hadham Palace, about 2.6 miles north, is one of the historic houses in the wider area around Widford. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Next to the main roofs there’s normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.

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

Electronic leak detection in Widford: what you get

Our ELD report shows where each breach was found with photos. It tells your roofer exactly where to repair instead of hunting for the leak. Repair costs are not part of the report, so your roofer prices the work. Testing again after repairs can confirm the breaches have been dealt with if the build-up allows. Results come in a written report with photos. Common reasons to book are leaks under green or ballasted roofs and repairs that haven’t stopped the leak, on flat roof membranes, roof terraces and balconies and single-ply roofs.

In a village or hamlet like Widford, flat roofs are usually on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them when booking.

Where we cannot see part of the flat roof membrane, the report says so. You’ll know exactly what was inspected and what wasn’t, and what we’d suggest next.

How we price electronic leak detection

Prices vary from roof to roof, for these reasons:

  • Chimneys, valleys, parapets and other details
  • Building height and the viewpoints available
  • Any need for thermal images or a drone flight
  • Roof area

Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the exact price before booking.

What we need to know

When you call or email, these details help:

  • Access details, such as a loft hatch or a shared roof
  • What made you get in touch
  • When you need the report by
  • Pictures of the roof from a safe spot, if you have them

To book a survey, phone 07833 053749 or email us with the address and what you’d like to know about the roof. You’ll know the price before anything is booked.

Why it is worth a survey now in Widford

Water trapped under a membrane can soak insulation and decking. Finding the breach sooner limits that. Around Widford, older homes often have old roof timbers, where water from a failed roof can cause rot if it’s left.

Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You will know the figure before booking.

Why book with us

  • Professional indemnity and public liability insurance
  • Over 20 years’ experience
  • 5,000+ roofs surveyed

Useful tips for Widford property owners

Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Tips:

  • Ask contractors to protect the membrane
  • Do not let outlets block
  • Act on new leaks promptly
  • Keep a note of leaks after rain

If we think the leak is not coming through the membrane, the report says so, with a suggestion of what to check next.

Limit foot traffic on flat roofs. Feet and dropped tools are a common cause of holes.

Signs you need electronic leak detection in Widford

Holes in a membrane often come from feet, tools or debris. Many are tiny but water still finds them.

A survey makes sense if you’ve noticed:

  • Gaps at membrane joints
  • Repairs that haven’t stopped the leak
  • Leaks through a covered membrane
  • Water coming in under a flat roof

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

Choosing a roof surveyor

  • What the report includes, and whether it has photos
  • Their report turnaround times
  • Their drone registration, if they fly one
  • Will they check the loft as well as the outside?

What to expect from a roof survey

What happens on the day

Where it is relevant and can be reached safely, the roof space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging. All in, the survey usually takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. In a hamlet or village like Widford, a postcode does not always lead to the right gate, so a few directions are welcome. The visit itself is the same as anywhere else.

  1. First, we confirm which roof areas are included.
  2. The surface is prepared for the chosen method.
  3. We work across the roof with the test equipment.
  4. Each breach found is located and recorded.
  5. You receive the results to pass to your roofer.

Getting ready for the survey

  • Clear the way to the loft hatch
  • Have keys ready for side gates, garages or roof access doors
  • Dig out any old roof reports or invoices

Arrange a survey

If you have photos of the roof, send them over. Take them safely from ground level or a window. To get started, call 07833 053749 or drop us an email.

Advice

Questions from Widford

Do you cover smaller places like Widford?

Yes. Widford is within the area we cover, which takes in towns, villages and rural addresses. Our area covers London and the South East. Let us know about access, parking and anything unusual about getting there as you book.

Does a conservation area affect roof work in Widford?

Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.

How does ELD work?

ELD passes a small electrical current across the roof to locate holes in the membrane. A breach lets the current through so we can pinpoint it.

Is my roof suitable for ELD?

ELD does not suit every roof. Some membranes conduct electricity and some roofs lack the layer the test needs. If your roof won’t work, we will say so at the start.

I live in a flat. Can you survey the roof?

Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we are allowed to reach.

Do you look in the loft space?

If the survey needs it and the roof space can be reached safely, yes. Please clear anything stored under the hatch, and if the loft cannot be reached safely, the report says so.

Will you repair the leak?

No, the test finds the breaches and your roofer repairs them. Your roofer uses the report to target the repair.

Checking the roof from ground level

Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.

A lot can be seen from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please don’t climb up for a closer look.
