Electronic leak detection for homes and businesses in Swerford
Some flat roofs can’t be tested electronically. Some membranes conduct electricity themselves, and some build-ups lack the layer the test needs below the membrane. If your roof isn’t suitable, we’ll tell you before any testing. 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. We survey commercial flat roofs, liquid-applied waterproofing and green roofs, and the problems we’re asked to look at most are leaks through a covered membrane and punctures from foot traffic or tools.
Flat roofs on exposed homes in small places like Swerford take more wind and rain, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, normally 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.
The report records the flat roof membrane as we found it on the day. That makes it useful now and a handy reference later, like when you want to compare after future work.

Why get it checked now?
A visual inspection can miss tiny holes. ELD picks up breaches a visual check might miss where the roof suits it. Older and listed buildings around Swerford may need consent and matching materials for repairs, so a defect found early gives time to plan the work properly.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before booking.

- Photos and a written report every time
- Customer satisfaction of 98%

What happens on the day
We’ll ask a few questions first, about the roof’s history, any leaks and past repairs. Then the inspection itself takes a length of time set by the size of the roof and how it’s built, which we’ll explain when we quote. For a village or hamlet like Swerford, the journey is planned beforehand: let us know about lanes, gates and parking. On the day, we inspect everything that’s safely in view, inside and out.
- You tell us about the roof and where water is showing.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
Before we arrive
- Find any records of previous roof work
- Keep pets out of the way during the survey
- Have keys ready for side gates, garages or roof access doors
How to book
Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. For any other survey, just ring 07833 053749 or drop us an email when you are ready.

Checking the roof from the ground
The one thing to avoid is getting up close. Roofs are fragile and slippery, and falls from height are serious. That’s where a survey comes in.
Keep a simple record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry, as it helps us focus the survey.
Flat and commercial roofs around Swerford
Older buildings in west Oxfordshire often have Cotswold stone slate roofs, and some Oxfordshire villages still have thatch. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops. What can be done to an older roof may depend on listing or a conservation area. The council is the place to check, along with Historic England’s list, before anyone quotes for re-roofing.
If you own one of the older houses in the streets near Church of St Mary, flat-roofed rear additions and dormers added over the years are worth checking. Whatever the street in Swerford, a roof costs least to look after when faults are caught early.

Common questions in Swerford
Do you cover smaller places like Swerford?
We do. A small place gets exactly the same survey as a big one.
Is Swerford in the area you cover?

No. Visible signs such as deflection or sagging are recorded, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.
Do you take photos of the roof?
Yes. We photograph the roof as we go, and they go into the written report.
Does ELD include fixing the breach?
No, the test finds the breaches and your roofer repairs them. Your roofer uses the report to target the repair.
Do you carry professional indemnity insurance?
We’re covered by professional indemnity and public liability insurance.
How fast do I get the report?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline as you book.
What we look for on each type of roof
Bituminous membranes
Bitumen roofs can frequently be tested electronically though the layers below matter.
Single-ply membranes
ELD often works on single-ply membranes but it depends on the product and layers.
Tips from our surveys
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Let us know about the membrane and build-up if you know it
- Check new waterproofing before handover
- Note where leaks show inside and when
- Act on new leaks promptly
The report records each breach location with photos. Pass it to your roofer to repair the breach points.
Make sure contractors protect the waterproofing when fitting equipment. Have the roof looked at after other work.
