Lower Assendon Electronic Leak Detection
Electronic leak detection to pinpoint holes in flat roof membranes for Lower Assendon, from an experienced roof surveyor. Every survey comes with a written report and photos.
- Leaks showing away from the breach
- New membranes needing a check before handover
- Holes around roof penetrations
Can I check my roof myself?
It is useful to keep a record: dates of leaks, photos from the ground and any work done on the roof. Share it with us as you book, as it helps us focus the survey.
A DIY look is useful, but it is not a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
Electronic leak detection in Lower Assendon
Some flat roofs can’t be tested electronically. Certain membranes conduct electricity, and some build-ups lack the layer the test needs below the membrane. We’ll say if ELD will not work on your roof at the start. Telling us what you know about the roof’s membrane and layers helps, including drawings, specifications or the roofer’s paperwork. It avoids arranging a test that can’t give results. Common reasons to book are new roofs to check before paving or planting and leaks under green or ballasted roofs, on commercial flat roofs, liquid-applied waterproofing and single-ply roofs.
In a village or hamlet like Lower Assendon, flat roofs are usually on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: outlets, upstands, edges and the covering itself. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included when booking.
What you get is a clear record of the flat roof membrane on the day we saw it. That makes it useful now and a handy reference later, such as when you want to compare after future work.

What happens if roof problems are left?
Chasing a leak again and again is frustrating. A report showing the breach points gives your roofer a clear target. For an older or listed building in a place like Lower Assendon, repairs may need matching materials and consent, so a defect found early gives time to plan the work properly.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before booking.

What happens on the day
Photos are taken throughout the visit, so the report shows exactly what we saw. We take close-ups from wherever is safe. A typical visit takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Older rural homes like those around Lower Assendon can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints.
- We start by finding out what the roof is made of and where it leaks.
- The roof is assessed to see if electronic testing will work on it.
- The method depends on the membrane and what sits above and below it.

- You get a report showing where each breach is, for your roofer to repair.
How to prepare

These are some of the problems a survey can pick up:
- Failed seams and laps

Electronic leak detection around Lower Assendon
About 1.6 miles south-west lies Greys Court, a reminder of how long the area around Lower Assendon has been built on. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years. West Oxfordshire’s older buildings frequently carry Cotswold stone slates, and a few villages in the county keep their thatch. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
The streets around a church like Church of St Anne are often among the oldest in a place, and if yours is one of the older homes 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. For landlords with property near Henley-On-Thames station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

Lower Assendon questions
Is Lower Assendon in the area you cover?
We do. Every survey there gets the same written report with photographs.
Is Lower Assendon within the area you cover?
Yes, we do. We work right across London and the South East, from towns to the smallest villages. Longer journeys are simply planned beforehand.
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 build-up first.
Can you tell me if my roof has asbestos?
No. Our report may flag materials that could contain asbestos, but confirming it is a job for a specialist asbestos surveyor. Buildings built or refurbished before 2000 may contain it.
Do you take photos of the roof?
Yes. The report includes photos of what we found, so you can see each point for yourself.
Do you climb onto every roof?
Not always. Safety comes first, and fragile or steep roofs can’t always be walked on. We use safe viewpoints, the roof space and a drone where it applies.
How many surveys have you done?
More than 5,000 surveys over 20+ years.
