Electronic Leak Detection in Naphill
Find out what’s going on with the flat roof membrane before you decide what to do next. We carry out electronic leak detection in Naphill, with photographs and a clear written report.
- Leaks through a covered membrane
- Leaks showing away from the breach
- Holes left by work on the roof
How electronic leak detection works in Naphill
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 aren’t part of the report, so your roofer prices the work. Testing again after repairs can confirm the breaches have been dealt with, where the roof still suits the method. You get a report with photographs. If you are worried about leaks showing away from the breach and new roofs to check before paving or planting, a survey will tell you what’s going on, on roof terraces and balconies, single-ply roofs and green roofs alike.
Flat roofs on exposed homes in small places like Naphill take more wind and rain, which is hard on edges, upstands and joins in the covering. Older felt roofs, often around 15–20 years in life, 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.
After the visit, you get a written report with photographs, emailed to you. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

Your questions about electronic leak detection in Naphill
How do I find out if my home in Naphill is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
Do you cover smaller places like Naphill?
Yes, Naphill is covered. We work right across London and South East England, from towns to the smallest villages. Longer journeys are simply planned ahead of time.
Which days do you carry out surveys?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Just tell us the days that suit you.
Can you find leaks on a covered flat roof?
Sometimes. It depends on the build-up and the layers above the membrane and parts may need to be lifted. We will discuss it before we quote.
Will you fly a drone over my roof?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and every flight depends on the airspace and the weather.
How long will testing take?
Testing normally takes a length of time set by the membrane area and the build-up, which we’ll explain when we quote.
Is this an asbestos survey?
No. Asbestos surveys and testing are not part of what we do. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them, and recommend a specialist asbestos surveyor checks them before they’re disturbed.

How the survey changes by roof type
Single-ply membranes
Many offices and units have single-ply roofs. Laps and fixings are where holes frequently appear.
EPDM rubber roofs
Some EPDM membranes conduct electricity which can limit electronic testing. We will tell you if yours is not suitable.
Flat roofs in Naphill
The wider area around Naphill has a long history of building, with Hughenden Manor about 1.5 miles south-east. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first. Thatch survives on some older buildings in Buckinghamshire’s villages. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
The streets around a church such as Church of St Botolph are often among the oldest in a place, and if your house is among the older ones 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. If you let a flat or house near Saunderton station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. For businesses in and around places like Eden, the flat roofs over shops and commercial units are worth checking before a leak, not after.
Naphill is about 3 miles north-west of High Wycombe, in Buckinghamshire. Wherever you are in Naphill, we can carry out electronic leak detection at your property, on a weekday, Saturday or Sunday. Naphill is one of the towns and villages in Buckinghamshire where we work for electronic leak detection. You can also see our page for Reading.
We survey roofs across HP14 for electronic leak detection and the streets around it. Whether your property is on Christopher Close, Main Road and Purssells Meadow or a nearby road, we can help. If you’re just outside Naphill, we cover Walter's Ash (1 mile north-west), Lower North Dean (1 mile north-east), Hughenden Valley (1 mile east), Upper North Dean (1 mile north) and Downley (1 mile south). Larger places within reach include Aylesbury (11 miles north), High Wycombe (3 miles south-east), Chesham (8 miles north-east), Marlow (6 miles south), Amersham (8 miles east) and Beaconsfield (7 miles south-east).
What’s near Naphill

What affects the price in Naphill
Every roof is different, so prices are confirmed before booking. These are the things that affect it:
- Building height and the viewpoints available
- The roof’s overall size
- Whether it is a home or a commercial building
- How many separate roofs there are, such as extensions, dormers and garages
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You’ll know the price for your roof before booking.
Helping us price your survey
These details help when you get in touch:
- The property’s address and postcode
- When you need the report by
- Photos of the roof, taken safely from ground level or a window
- Any marks or damp showing indoors
Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, ring 07833 053749 or email us with the address and the days you’d prefer.
What happens on the day
We photograph the roof as we go, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available. A typical visit takes more time on a big roof than a small one, with the construction of the roof playing a part too. Cottages and farmhouses around Naphill often have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can be seen safely, and anything we cannot see is noted.
- 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.
Before the survey
- Note where any stains or damp appear
- Have any paperwork from past roof work to hand
- Clear the way to the loft hatch
Arrange a survey
To book a survey, call 07833 053749 or email us with the address and what you’d like to know about the roof. We will confirm the price before booking.
Advice
What we can’t see
This is not a RICS building survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Fixing the holes we find
- Moisture spread under the membrane
- Roofs whose membrane or build-up is not suitable
If you’re not sure which survey you need, phone 07833 053749 or email us and we will give you a straight answer before booking. What our survey covers.
Roof types and parts we check
- Commercial flat roofs
- Roof terraces and balconies
- Liquid-applied waterproofing
- Green roofs
- Single-ply roofs
- Flat roof membranes
What happens if roof problems are left?
Repeated call-outs for the same leak add up. A clear record of where the breaches are helps break that cycle. For older village homes like those around Naphill, the right replacement materials are not always easy to find quickly. That is one more reason to find defects before they become urgent.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.

Tips that help
Small things make a difference, both for the survey and for the roof itself. Our tips:
- Test new membranes before covering them
- Do not leave water getting in
- Make sure trades protect the waterproofing
- Note where leaks show inside and when
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.
