Electronic leak detection in Bernards Heath: what you get
Water can travel under a flat roof membrane before it shows inside. So the stain inside rarely sits under the hole. ELD tests the waterproofing directly and locates the breach. We test and report, and the repair is for your roofer. On a suitable roof, it takes the guesswork out of finding the hole. The results then follow in a written report with photos. We survey flat roof membranes, commercial flat roofs and single-ply roofs, and common reasons people get in touch are breaches around outlets and penetrations and new membranes needing a check before handover.
Around a smaller place like Bernards Heath, flat roofs usually cover extensions, garages and dormers. Even a small flat roof can let lots of water into the room below. What it is covered in, and how well it was laid, decides what it needs. Ponding, splits and lifting edges are the signs to look for from a window.
The report works through the roof section by section, from the coverings down to the gutters, with a note and a photo for each point. It records what’s sound as well as what is not.

Tips from our surveys
There’s plenty you can do without going near the roof. Here’s what helps most:
- Clear flat roof outlets regularly
- Keep a note of leaks after rain
- Do not leave water getting in
- Tell us about the membrane and build-up if you know it
Where the evidence points to walls, copings or rooflights, we will note it, with a suggestion of what to check next.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.
Roof by roof
Bituminous membranes
Many flat roofs use bitumen-based membranes. The build-up decides which method will work.
Green and ballasted roofs
Parts of the covering may have to come up. We discuss this before quoting.
Flat roofs in Bernards Heath
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. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. Bernards Heath has a number of hotels within about a mile and a half, and like offices and blocks, hotels often sit under flat roofs. If you look after one, a leak through a flat roof can put a room out of use.
If yours is one of the older homes in the streets near Church of St Saviour, the flat roofs on later extensions tend to wear out long before the main roof. Take a building like Garden Fields Junior Mixed and Infant School: a large flat roof with lots of outlets and rooflights has many places where a membrane can fail. For hotels and guest houses around Bernards Heath, a roof problem found early is far less disruptive than one found by a guest, so it pays to find faults before guests do.

What we do, step by step
Once we’ve finished looking, we write up our findings as a photo-illustrated written report, sent to you by email. On timing, most surveys take longer on a large roof than a small one, and the build-up of the roof makes a difference too. Being in a smaller place like Bernards Heath doesn’t change how the visit works: we look from ground level, from windows, from the loft and from the roof where it is safe. It helps to show us anything you’ve already noticed.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Preparing for the visit
- Tell us about parking before the day
- Make a note of anything you’d like us to look at
- Gather any invoices or paperwork from past roof work

Related advice
What a survey costs
The price reflects the time and kit the roof needs. The main factors are:
- Building height and the viewpoints available
- How many separate roofs there are, such as extensions, dormers and garages
- The roof’s overall size
- The use of thermal imaging or a drone
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before booking.
Booking your survey
You do not need to know any roofing terms. It’s enough to let us know:
- The type of building and roof, such as pitched or flat
- The reason for the survey, such as buying, a leak or storm damage
- The address and postcode of the property
- Access details, such as a loft hatch or a shared roof
We survey roofs seven days a week. To find a date that works for you, ring 07833 053749 or send us an email.

Bernards Heath: your questions answered
Will you come out to Bernards Heath?
Yes, we do. We cover the whole of London and South East England, from towns to the smallest villages. The journey is planned ahead, so it helps to know about access.
How do I find out if my home in Bernards Heath is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you take photos of the roof?
Yes. Photographs are taken throughout the survey, and they go into the written report.
Can you find leaks on a covered flat roof?
On some roofs, yes. Covered roofs limit the methods we can use, so we check the build-up first.
Is this a RICS survey?
No. We’re experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you will need a RICS survey as well.
How does ELD work?
A sound membrane blocks the test current, so wherever there is a hole, it passes through. That lets us find breaches that are too small to see.
Will you check the loft?
Normally, if there’s one and it can be reached safely. The loft space can show things the outside cannot, like damp timbers, staining or daylight.
Why act early in Bernards Heath
A visual inspection can miss tiny holes. ELD picks up breaches a visual check might miss where the roof suits it. In an older home around Bernards Heath, water from a roof defect can get into timber and plaster, and that is a much bigger job than the original defect.
To find out what your survey will cost, phone 07833 053749 or drop us an email with the address and a few details. We will confirm the figure before booking.
