Electronic leak detection in Great Sampford: what you get
Roofs covered with paving, ballast or planting need more thought. What sits on the membrane can affect which method will work, and some may need lifting. We’ll discuss it with you when we quote. Any details of the build-up help because they show what’s under the surface. We’ll tell you if the roof can’t be tested. We survey liquid-applied waterproofing, flat roof membranes and commercial flat roofs, and the problems we’re asked to look at most are a flat roof leak that can’t be traced and waterproofing to test before it’s covered.
In a small place like Great Sampford, 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. Rubber and GRP last longer, though trims and joints still need a look. On an exposed roof, the edges tend to go first.
Every survey ends with a written report, with photographs, emailed to you. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

Why act early in Great Sampford
Some breaches are too small to see. ELD picks up breaches a visual check might miss where the roof suits it. In a small place like Great Sampford, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You’ll know the figure before booking.

FAQs for Great Sampford
Is Great Sampford within the area you cover?
Yes. Great Sampford is within the area we cover, which takes in towns, villages and rural addresses. We work right across London and South East England. Just mention lanes, gates or anything else about the route when you book.
Does a conservation area affect roof work in Great Sampford?
The council and Historic England’s list are the places to check. It is worth checking before planning roof work, as both can affect what’s allowed.
Is this a RICS survey?
No. We check the roof, not the whole building, and it is not a RICS Level 2 or Level 3 survey. Many buyers have both.
Can you survey a shared roof?
Yes, once whoever controls the roof agrees access. We check the parts we are given access to, and the report makes that clear.
Do you use low-voltage or high-voltage testing?
The roof decides the method. You’ll know which method we plan to use before we start.
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 roof first.
How does ELD work?
It uses an electrical current to find breaches in a flat roof membrane. The current only gets through where the membrane is breached so we can pinpoint it.
Honest limits
Before booking, it’s worth knowing what a survey won’t do:
- Carrying out the repair work
- Moisture spread under the membrane
- Some conductive membranes

What we look for on each type of roof
EPDM rubber roofs
Certain rubber membranes are conductive, which can rule out some methods. We’ll tell you if yours isn’t suitable.
Green and ballasted roofs
Some layers may need lifting for testing. We explain what’s needed when we quote.
The survey, step by step
On the day, we begin with a quick chat about the roof and anything that is worrying you. After that, we check everything we can see safely, from ground level, from windows, in the loft space and by drone where applicable. The survey typically takes as long as needed for the membrane area and the build-up, which we’ll explain when we quote. In a small place like Great Sampford, access is normally the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Getting ready for the survey
- Buyers: confirm access with the estate agent or seller
- Leave side gates unlocked

What else we do in Great Sampford
Do you need electronic leak detection in Great Sampford?
Joints and laps in a membrane can fail over time. A gap that’s hard to see can let water in for months before it shows.
Typical things we are asked to look at include:
- Breaches hidden under paving or planting
- Stains far from any visible defect
- Holes around roof penetrations
- Leaks that return after repairs
For an older house near a landmark such as Church of St Michael, the joins between later flat roofs and the old walls are where problems normally start.
Questions to ask before you book
- Is there a chance to talk the report through?
- Are they insured for the work?
- How soon the report will arrive
- Whether any drone flown is registered with the CAA
Electronic leak detection in Great Sampford: local notes
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 fill the gaps in between, on extensions, garages, dormers and business premises. An older home may be listed, or stand in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. Re-roofing in different materials may need permission there.
Anyone responsible for a site like Great Sampford Community Primary School will know that a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.

Tips from our surveys
Here are a few things we’d tell any owner:
- Check new waterproofing before handover
- Share any drawings of the roof
- Don’t leave water getting in
- Keep a note of leaks after rain
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
ELD before paving, ballast or planting goes on is worth considering. It’s easier to find holes before more layers are added.
