Electronic leak detection in Upper North Dean
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It helps trace a leak you already have or check a new membrane before handover. We quote for each roof based on its size and build-up. We can test on weekdays and at weekends when conditions allow. Let us know about your roof to find out more. We survey green roofs, single-ply roofs and liquid-applied waterproofing, and people most frequently book us about leaks through a covered membrane and patched roofs that still leak.
Somewhere as small as Upper North Dean, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them when you book.
The report is written in plain words, so it makes sense without any roofing background. Photographs show what each point refers to.

Common roof problems in Upper North Dean
If a flat roof keeps leaking after patching, the hole may be elsewhere. Electronic testing helps pinpoint it.
These are some of the problems a survey can pick up:
- Repairs that haven’t stopped the leak
- New roofs to check before paving or planting
- Gaps at membrane joints
- A flat roof leak that cannot be traced
If you own a rental within reach of Saunderton station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Choosing a roof surveyor
- Their report turnaround times
- How they plan to inspect the roof safely
- How long they’ve been surveying roofs
- Their insurance cover
Before and after the survey
Most of what helps is simple and safe from the ground. A few suggestions:
- Don’t keep patching the same spot
- Ask contractors to protect the membrane
- Record dates and spots where water appears
- Clear flat roof outlets regularly
Keep the report with the roof’s records. It shows the condition of the membrane on that date.
Act on leaks quickly. Water under a membrane can spread.
Rented homes, blocks and businesses
Letting agents often book on a landlord’s behalf, with the report sent to whoever needs it. Access is agreed with the tenant in advance.
Where a roof is shared: we need access agreed with the freeholder or managing agent. Mention it when you contact us and we will plan the visit with that in mind.
Upper North Dean questions
Do you carry out roof surveys in Upper North Dean?
Yes, Upper North Dean is within the area we cover. We cover the whole of London and South East England. Just phone 07833 053749 or use the contact form and let us know about the property.
Does a conservation area affect roof work in Upper North Dean?
We can’t confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material.
Does the weather affect the survey?
Light rain is normally fine; heavy rain and wind are different. In strong wind or a downpour, a drone cannot fly and access may not be safe, and we’d agree another day.
How do I arrange electronic leak detection in Upper North Dean?
To arrange a survey, ring 07833 053749 or send us an email and let us know the address and what you want to find out. We’ll confirm the price and find a day that suits.
What does the report include?
You get our findings in writing, part by part, with photos, and ends with what we recommend. The most urgent items are made clear.
Can you find leaks on a covered flat roof?
It can be possible, depending on the roof. What sits on the membrane affects the method so we check the roof first.
Do you carry professional indemnity insurance?
Our surveys are covered by professional indemnity and public liability insurance. Ask if you need details for a managing agent or building owner.
What this survey can’t tell you
Some things can’t be seen without opening up the roof, so a survey has limits:
- Fixing the holes we find
- Water entering through details rather than the membrane
- Some conductive membranes

Flat and commercial roofs around Upper North Dean
About 2.4 miles south lies Hughenden Manor, a reminder of how long the area around Upper North Dean has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area. A number of Buckinghamshire villages keep thatched roofs on their older buildings. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
The streets around a church such as Speen Church (Baptist) are often among the oldest in a place, and if you own one of the older houses nearby, flat-roofed rear additions and dormers added over the years are worth checking. For site and facilities teams at buildings such as Speen CofE VA School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

- The roof is assessed to see if electronic testing will work on it.
- We pick the low-voltage or high-voltage method that suits the roof.
