Chilswell Electronic Leak Detection
We carry out electronic leak detection in Chilswell and the rest of Oxfordshire. We survey on weekdays, Saturdays and Sundays.
- Damp inside with no sign on the roof
- Breaches around outlets and penetrations
- Holes left by work on the roof
Tips from our surveys
These tips come from what we see on roofs every week, before and after a survey:
- Tell us about the membrane and build-up if you know it
- Ask contractors to protect the membrane
- Limit access to the roof
- Keep a note of leaks after rain
Where the evidence points to walls, copings or rooflights, we’ll note it, so other causes can be checked.
Act on leaks quickly. Water under a membrane can spread.
How electronic leak detection works in Chilswell
Not every flat roof suits electronic testing. 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 before any testing. Telling us what you know about the roof’s membrane and layers helps, such as drawings or specifications. It avoids arranging a test that can’t give results. Common reasons to book are holes around roof penetrations and failed seams and laps, on green roofs, liquid-applied waterproofing and roof terraces and balconies.
In a small place like Chilswell, a flat roof can stand in the open, so edges, upstands and laps take a beating. Older felt roofs, often around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. On an exposed roof, the edges tend to go first.
We write the report in plain English, so you don’t need to be a roofer to follow it. Each point is backed by a photograph where possible, with the urgent items made clear.

What a survey costs
To price your survey, we look at:
- Chimneys, valleys, parapets and other details
- If the survey needs thermal imaging or a drone
- How tall the building is and how easy the roof is to see
- House, block, shop or office
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the price for your roof before booking.
Getting in touch
There’s no need for technical words. It is enough to let us know:
- Whether there’s a loft hatch, a shared roof or tricky access
- What made you get in touch
- Any stains, drips or damp patches you’ve seen indoors
- The style of property, from a terrace to a block
A quick phone call is normally the easiest start: phone 07833 053749 or send us an email, and we’ll ask about the building and what you need. You will have a price before anything is arranged.
How the survey works
It helps to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. It helps us focus on what matters most to you. Most visits take 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 Chilswell 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, and anything we cannot see is noted.
- 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.
- We pick the low-voltage or high-voltage method that suits the roof.
- Testing runs across the roof to locate breaches in the membrane.
- You get a report showing where each breach is, for your roofer to repair.
Getting ready for the survey
- Point out any leaks or damp patches
- Leave a clear route to the loft
- Have any questions written down, so nothing gets missed
Booking a survey
Our phone lines are open seven days a week, including Saturdays and Sundays. To book or ask a question, call 07833 053749 or email us.

Flat roofs in Chilswell
West Oxfordshire’s older buildings often carry Cotswold stone slates, and a few villages in the county keep their thatch. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. About 2.6 miles north-east lies Holywell Manor, a reminder of how long the area around Chilswell has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead.
If you own a rental within reach of Oxford station, the flat roof over a let home is worth a look before it becomes a tenant complaint. If you look after a shop, office or commercial unit, for example near Westgate Shopping Centre, outlets and upstands on commercial flat roofs are the places to check before trouble starts.
Chilswell is about 3 miles south-west of Oxford, in Oxfordshire. Chilswell gets the same service as everywhere else we work: a careful inspection, photographs and a written report. Our area takes in places right across Oxfordshire, large and small.

Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work.
If the property is let, the agent or a tenant can let us in. We survey on weekdays and at weekends, which helps when tenants work during the week.
What we’re asked to look at in Chilswell
New membranes can have defects from installation. Testing before the roof is covered or handed over helps find them.
It’s worth booking a survey if you’ve seen:
- Holes around roof penetrations
- Holes left by work on the roof
- Waterproofing to test before it is covered
- Leaks that return after repairs
Anyone responsible for a site like Matthew Arnold School will know that a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.
What to check before booking
- Whether any drone flown is registered with the CAA
- When you’ll get the report
- What follow-up you get after the report
- How long they’ve been surveying roofs
Why it’s worth a survey now in Chilswell
Some flat roof leaks come from walls or details. ELD helps rule the membrane in or out so attention can go to the right place. For an older or listed building in a place like Chilswell, repairs may need matching materials and consent, so a defect found early gives time to plan the work properly.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.

Questions from Chilswell
Do you carry out roof surveys in Chilswell?
Yes, Chilswell is within the area we cover. We survey roofs across London and South East England. Just phone 07833 053749 or send us an email and let us know about the property, and we’ll talk through which survey suits.
Do you cover smaller places like Chilswell?
Yes, smaller places are covered as well as towns. Our area covers London and South East England. Just mention lanes, gates or anything else about the route when booking.
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, and the report records anything we couldn’t see.
How soon will I get the report?
It depends on the package: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. Reports are sent by email.
Will you fly a drone over my roof?
Yes, where it is applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.
Can you give me structural calculations?
No. We’re roof surveyors, not structural engineers, and it does not include calculations. If we see signs that need an engineer’s opinion, we’ll recommend one.
Is this a RICS survey?
No. This is a survey of the roof only, and it isn’t a RICS Level 2 or Level 3 survey. Many buyers have both.
