Electronic leak detection in Barwick: what you get
You get a report showing the location of each breach, with photographs. It tells your roofer exactly where to repair rather than guessing. Repair costs aren’t part of the report; that is for your roofer to price. 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. If you’ve noticed repairs that haven’t stopped the leak and holes left by work on the roof, a survey will tell you what’s going on.
Flat roofs on exposed homes in small places like Barwick take more wind and rain, so edges, upstands and laps take a beating. Older felt roofs, often around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. On an exposed roof, the edges tend to go first.
The report works through the roof section by section, from the coverings down to the gutters. It records what’s sound as well as what isn’t.

Barwick: your questions answered
Do you cover smaller places like Barwick?
Yes. Barwick is within the area we cover, which takes in towns, villages and rural addresses. We survey roofs across London and South East England. Let us know about access, parking and anything unusual about getting there as you book.
Is my home in Barwick listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Is my roof suitable for ELD?
ELD doesn’t suit every roof. Certain membranes are conductive, and some build-ups lack a suitable layer below. If your roof won’t work, we will say so at the start.
Can you tell me if my roof has asbestos?
No. Our report may flag materials that could contain asbestos, but confirming it is a job for a specialist asbestos surveyor. It may be present in buildings built or refurbished before 2000.
What’s the best way to book?
Simply ring 07833 053749 or use the contact form. We’ll ask a few questions, confirm the price and agree a date.
Does ELD include fixing the breach?
No, the test finds the breaches and your roofer repairs them. The report gives your roofer the locations.
What is electronic leak detection?
The waterproofing membrane normally stops an electrical current, so wherever there is a hole, it passes through. That lets us find breaches that are too small to see.
Why get it checked now?
Cutting open a flat roof to find a leak can cause more damage. Electronic testing finds the hole first, so the repair can be targeted. Older cottages and farmhouses around Barwick can have roof timbers that have been there a very long time, and water through a failed covering can rot timber if it’s left.

What we do, step by step
We work from the outside in: outside views come first, then the loft space if there’s safe access. All told, expect longer on a large roof than a small one, and the build-up of the roof makes a difference too. Older roofs in small places like Barwick can have low, tight loft spaces, so let us know about the loft hatch and any ladder. We only go where it is safe.
- You tell us about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
Before we arrive
- Let us know about any leaks, stains or damp patches you know of
- Find any records of previous roof work
- Leave a clear route to the loft
Arrange a survey
A quick phone call is usually the easiest start: phone 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.

Flat and commercial roofs around Barwick
The wider area around Barwick has a long history of building, with Much Hadham Palace about 2.9 miles east. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If you own a rental within reach of Ware station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

Should I look at the roof myself first?
Look up at the roof after a storm, from the ground: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
Your own check is a good start, but it isn’t a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
What a survey costs
What a survey costs depends on the time and equipment it needs. That comes down to:
- If the survey needs thermal imaging or a drone
- Height and safe access
- How big the roof is
- The type of building, from a house to a block or an office
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before booking.
Helping us price your survey
To price your survey accurately, we’ll ask about:
- What’s prompted the survey
- Your timetable, such as an exchange date
- Whether there is a loft hatch, a shared roof or tricky access
- The kind of building and roof involved
Booking is simple: just ring 07833 053749 or email us and give us some details about the property and we’ll explain which survey suits. We confirm the price before anything is booked.
Rented homes, blocks and businesses
Any of our surveys can be booked by landlords, agents and building managers in Barwick. To discuss a property or a block, phone 07833 053749 or use the contact form.
Where a roof is shared: we need access agreed with whoever owns or manages the building. Mention it when you contact us and we will plan the visit with that in mind.
What we are asked to look at in Barwick
New membranes can have defects from installation. ELD on a new roof can show holes before they cause leaks.
People typically book a survey after spotting something like this:
- Punctures from foot traffic or tools
- New membranes needing a check before handover
- Leaks through a flat roof with no obvious cause
- Holes around roof penetrations
For an older house near a landmark such as St Mary's, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
Questions to ask before you book
- Whether the loft is part of the inspection
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Their insurance cover
- Whether the price includes VAT
