Common questions in Lewknor
Do you cover Lewknor?
Yes, Lewknor is one of the places we work. Every survey there gets the same written report with photos.
Does a conservation area affect roof work in Lewknor?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
How long does electronic leak detection take?
It usually takes more time on a big roof than a small one, with the construction of the roof playing a part too.
I live in a flat. Can you survey the roof?
Yes, if the freeholder or managing agent agrees access. We check the parts we are given access to.
Do I need to be at home?
Not necessarily. If we only need the outside, we can agree that in advance, but the loft and any rooms with damp need someone to let us in.
Do you take photos of the roof?
Yes, every report has them. Pictures sit next to the findings they show.
What happens next?
We email you the written report with photos and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Electronic leak detection in Lewknor: what you get
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It works with an electrical current which can only get through the membrane at a breach. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. You get a written report with photos of each breach found. We survey roof terraces and balconies, flat roof membranes and single-ply roofs, and common reasons people get in touch are stains far from any visible defect and a flat roof leak that can’t be traced.
Some older homes in villages like Lewknor are listed or in a conservation area, which can shape what a new flat roof may look like. If you are planning work, check with the council first. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.
We write the report in plain English, so you do not need to be a roofer to follow it. Each point is backed by a photo where possible, and recommendations are put in order of urgency where relevant.

Why get it checked now?
Testing a new membrane before it is covered is easier than tracing a leak later. Covered roofs are harder to test. Outbuildings and barns around Lewknor are easy to forget, but a failed roof there can spoil what’s stored inside. It’s worth including them in a survey before a winter does the damage.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before booking.
Why choose Independent Roof Survey in Lewknor
- 20+ years’ experience
- A sub-250g drone, flown with a CAA Flyer ID and Operator ID
- An independent view of the roof
- Surveys seven days a week

When to book a survey in Lewknor
When the membrane is buried, holes can’t be seen at all. ELD can work on some covered roofs though it depends on the layers.
Common reasons to book include:
- New roofs to check before paving or planting
- Leaks through a covered membrane
- Leaking laps in the waterproofing
- Damp inside with no sign on the roof
If you look after a building such as Lewknor Church of England Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
Before you book anyone
- What experience they bring
- Whether you can ask questions once you have the report
- Their insurance cover
- Whether the inside of the roof is included
DIY checks: what’s safe
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, as it helps a surveyor trace the cause.
How the survey works
Before we start, let us know why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. The visit normally takes longer on a large roof than a small one, with the construction of the roof playing a part too. Somewhere like Lewknor needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. On the day, we inspect everything that’s safely in view, inside and out.
- First, you tell us about the roof build-up and where water is showing.
- We check that the membrane and build-up suit electronic leak detection.
- The method depends on the membrane and what sits above and below it.
- We test the membrane and find where current is passing through it.
- We send a report with photos of each breach so your roofer can repair it.
Before the survey
- Dig out any old roof reports or invoices
- Keep pets inside or away from the areas we’re looking at
- Make a note of anything you’d like us to look at

What electronic leak detection looks like in Lewknor
Older buildings in west Oxfordshire often have Cotswold stone slate roofs, and some Oxfordshire villages still have thatch. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. About 1.6 miles north-west lies Adwell House, a reminder of how long the area around Lewknor has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area.
The streets around a church such as Church of St Margaret are often among the oldest in a place, and if you own one of the older houses nearby, the joins between later flat roofs and the old walls are where problems usually start.
