About our electronic leak detection in Steventon
We carry out electronic leak detection on flat roofs in Steventon and across London and South East England. Testing typically takes a time that depends on the size of the roof and how it’s built, which we’ll explain when we quote. Every roof is quoted on its size and build-up. You get a photo-illustrated written report. We’re often asked to look into patched roofs that still leak and stains far from any visible defect, across liquid-applied waterproofing, green roofs and flat roof membranes.
Flat roofs on exposed homes in small places like Steventon take more wind and rain, so edges, upstands and laps take a beating. Felt roofs, which frequently last around 15–20 years, usually show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
After the visit, you get a photo-illustrated written report, sent by email. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

Do you need electronic leak detection in Steventon?
New membranes can have defects from installation. Testing before the roof is covered or handed over helps find them.
Most people get in touch when they’ve noticed something like this:
- Leaks under green or ballasted roofs
- Repairs that haven’t stopped the leak
- Leaking laps in the waterproofing
- Damp inside with no sign on the roof
Landlords with a home close to Didcot Parkway station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.

FAQs for Steventon
Do you cover Steventon?
Yes, Steventon is within the area we cover. Our area covers London and the South East. Just phone 07833 053749 or email us and tell us about the property.
Does a conservation area affect roof work in Steventon?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
What’s in the survey report?
It sets out what we found, why it matters and what we recommend, with photos throughout. It also says if any part of the roof couldn’t be seen safely.
Is the repair part of the test?
No, our part is finding the breaches. Your roofer uses the report to target the repair.
How long will testing take?
The roof’s size and build-up decide how long it takes. You’ll know roughly how long before we start.
Will you walk on the roof?
Not unless it is safe. Most of what we need can be seen from safe viewpoints, the loft and, where applicable, a drone, and anything out of sight is recorded in the report.
Are you structural engineers?
No. We’re roof surveyors, not structural engineers, and it does not include calculations. We will recommend an engineer if we see signs that call for one.
What happens on the day
We look at the roof from outside and, where it’s relevant and there is safe access, from inside the loft space too. In the loft, the signs we look for are staining, damp, daylight and sagging. The whole visit usually takes more time on a big roof than a small one, with the construction of the roof playing a part too. Older rural homes like those around Steventon can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can be seen safely.
- 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.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Preparing for the visit
- If it is not your property yet, arrange access through the agent
- Find any records of previous roof work
- Let us know about any leaks, stains or damp patches you know of
How to book
Most bookings start with a short call: call 07833 053749 or drop us an email and we’ll ask a few questions about the roof. You will have a price before anything is arranged.
Advice
Practical tips
Small things make a difference, both for the survey and for the roof itself. Some pointers:
- Avoid repeated repairs without finding the cause
- Keep a note of leaks after rain
- Get leaks traced quickly
- Check new waterproofing before handover
The report records each breach location with photos. Pass it to your roofer to repair the breach points.
Limit foot traffic on flat roofs. Feet and dropped tools are a common cause of holes.
Flat roofs in Steventon
Older buildings may be listed or sit in a conservation area. Historic England’s list shows listed buildings, and the council can say whether a street is in a conservation area. In either case, a change of roofing material may need consent. Cotswold stone slates are found on older buildings in west Oxfordshire, and thatch survives in some of the county’s villages. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
Take an older house close to Church of St Michael and All Angels: later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. If you look after a building like St Michael's Church of England Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Should I look at the roof myself first?
You can learn a lot from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please don’t climb up for a closer look.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
What we look for on each type of roof
Single-ply membranes
Punctures from foot traffic and equipment are common on single-ply roofs. Testing helps find them.
Liquid-applied waterproofing
Liquid waterproofing has no laps, but can still have thin spots or holes. Suitability for ELD depends on the system.
