Fields End Electronic Leak Detection
Electronic leak detection across Fields End, with over 20 years’ experience behind it. Every survey ends with a written report and photos.

- Damage from equipment installers
- New membranes needing a check before handover
What we’re asked to look at in Fields End
Water travels under flat roof membranes. The stain inside can be far from the hole which makes it hard to find by looking.
A survey can pick up problems like:
- Gaps at membrane joints
- Leaks showing away from the breach
- Punctures from foot traffic or tools
- Patched roofs that still leak
If you let a flat or house near Hemel Hempstead station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Choosing a roof surveyor
- What they will not be able to tell you
- Whether VAT is added on top
- Whether you can ask questions once you have the report
- When you’ll get the report
Electronic leak detection in Fields End
ELD can be carried out in more than one way. Low-voltage methods usually need a wet roof surface, while high-voltage testing needs a dry, exposed membrane. The right method depends on the membrane and the build-up of the roof, and we will explain our choice. If neither method suits your roof, we’ll tell you at the outset. Common reasons to book are waterproofing to test before it’s covered and leaks under green or ballasted roofs, across green roofs, single-ply roofs and roof terraces and balconies.
In a small place like Fields End, a flat roof can stand in the open, so edges, upstands and laps take a beating. Felt roofs, which frequently last around 15–20 years, normally show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are typically the first part of a flat roof to go.
Nothing in the report is left vague: if work is needed, the report says so clearly, and where it can wait, that is said too.

Why it’s worth a survey now in Fields End
Leaks left running can wet the insulation and deck. Finding the breach sooner limits that. Older and listed buildings around Fields End may need consent and matching materials for repairs, so a defect found early gives time to plan the work properly.
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You’ll know the exact price before booking.

Tips from our surveys
Small things make a difference. Our tips:
- Test new membranes before covering them
- Act on new leaks promptly
- Record dates and spots where water appears
- Ask contractors to protect the membrane
Where the evidence points to walls, copings or rooflights, we’ll note it, with a suggestion of what to check next.
Do not leave a flat roof leak running. Water under a membrane can spread.
What we do, step by step
Safety comes first on every visit. Everything that can safely be seen is inspected, and if part of the roof can’t be seen, the report says so. The survey normally takes 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 Fields End can have low, tight loft spaces, so it helps to know whether there’s a loft hatch and how easy it is to reach. Only areas that can be reached safely are inspected.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Before we arrive
- For flats, make sure roof access has been agreed
- Check the loft hatch can be reached
- Make a note of anything you’d like us to look at

Flat roofs in Fields End
An older home may be listed, or stand in a conservation area. Historic England’s list shows listed buildings, and the council can say whether a street is in a conservation area. Re-roofing in different materials may need permission there. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, and flat-roofed additions turn up almost everywhere. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
The streets around a church like St Alban's Church are often among the oldest in a place, and if you own one of the older houses nearby, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. Take a building like John F Kennedy Catholic School: a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail.

Should I look at the roof myself first?
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
What you can’t do safely is get up close. Roofs are fragile and slippery, and falls from height are serious. That part is for a survey.
Common questions in Fields End
Do you carry out roof surveys in Fields End?
Yes, Fields End is within the area we cover. Our area covers London and the South East. Just ring 07833 053749 or email us and let us know about the property.
Is my home in Fields End listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s 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.
Is my roof suitable for ELD?
It depends on the membrane and the build-up. Tell us what you know about the roof and we’ll check whether ELD will work.
Will you photograph what you find?
Yes. The report includes photographs of what we found.
Does the weather affect the survey?
A survey can usually go ahead in light rain. Heavy rain or strong wind can ground a drone and make the roof unsafe, so if conditions aren’t right we will arrange another day with you.
Is it the same as a RICS Level 2 or Level 3 survey?
No. This is a survey of the roof only, and it is not a RICS Level 2 or Level 3 survey. Many buyers have both.
Is the repair part of the test?
No, our part is finding the breaches. The report gives your roofer the locations.
