Electronic leak detection in Twyford, Hampshire
Electronic leak detection to pinpoint holes in flat roof membranes in Twyford, with drones and thermal imaging where they help. Call or email for a price.
- Leaks at pipes, outlets or fixings
- Gaps at membrane joints
- Leaks showing away from the breach
The survey, step by step
We will ask a few questions first, about the roof’s history, any leaks and past repairs. The inspection then takes a length of time set by the roof’s area and construction, which we set out in the quote. Older rural homes like those around Twyford 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.
- You tell us about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Preparing for the visit
- If it isn’t your property yet, arrange access through the agent
- Let us know where we can park nearby
- Have keys ready for side gates, garages or roof access doors
Booking a survey
Getting a price is simple: just phone 07833 053749 or send us an email, let us know about the property and we’ll explain which survey suits. The price is agreed up front.
Advice
Electronic leak detection in Twyford: what you get
Some flat roofs can’t be tested electronically. Some membranes conduct electricity themselves and some roofs don’t have a suitable layer beneath the membrane. If your roof is not suitable, we’ll tell you at the start. Any details you have about the membrane and build-up help us decide, such as drawings or specifications. It avoids arranging a test that cannot give results. We survey flat roof membranes, commercial flat roofs and single-ply roofs, and people most often book us about leaks under green or ballasted roofs and gaps at membrane joints.
In a small place like Twyford, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Older felt roofs, often around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are usually the first part of a flat roof to go.
Where we can’t see part of the flat roof membrane, the report says so. You’ll know exactly what was inspected and what wasn’t.

Different roofs, different checks
Inverted and paved roofs
On inverted roofs, insulation sits above the membrane and that changes how testing works.
EPDM rubber roofs
ELD on EPDM depends on the product and the layers. We look at this first.
Landlords, agents and block managers in Twyford
Businesses and commercial landlords can book us too. Bigger roofs take more time, and they’re priced for the size.
Managing agents and residents’ management companies use roof surveys to plan maintenance. The report sets out what needs attention now and what can wait, which helps when budgeting.

What else we do in Twyford
When to book a survey in Twyford
Flat roof membranes can be punctured by foot traffic, dropped tools or debris. Many are tiny but water still finds them.
A survey can pick up problems like:
- Holes left by work on the roof
- Patched roofs that still leak
- Leaks through a flat roof with no obvious cause
- Breaches around outlets and penetrations
For an older house near a landmark such as Church of St Mary, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
Choosing a roof surveyor
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- Will the report include photos?
- Their drone registration, if they fly one
- What they will not be able to tell you
Tips that help
Some practical points come up on survey after survey. They apply to most roofs:
- Don’t leave water getting in
- Clear flat roof outlets regularly
- Check new waterproofing before handover
- Avoid repeated repairs without finding the cause
Keep the report with the roof’s records. It shows the condition of the membrane on that date.
Consider testing a new membrane before it’s covered. Finding breaches is simpler at that stage.
Twyford: your questions answered
How do I find out if my home in Twyford is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do you cover smaller places like Twyford?
We do. A small place gets exactly the same survey as a big one.
Do you climb onto every roof?
Only when it is safe. Safety comes first, and fragile or steep roofs cannot always be walked on. We use safe viewpoints, the loft space and a drone where applicable.
How is ELD priced?
We quote for each roof individually. Let us know about the roof and where it leaks, and call 07833 053749 or email us for a quote.
What’s the best way to book?
Simply call 07833 053749 or use the contact form. After a few questions, we confirm the price and fix a day.
Is the repair part of the test?
No. ELD is testing only. You get the breach locations with photos for your roofer to repair.
Does electronic leak detection work on all membranes?
Not every roof is suitable. Certain membranes are conductive and some roofs lack the layer the test needs. If your roof won’t work, we will say so at the start.
What we cannot see
This is not a RICS building survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Fixing the holes we find
- The extent of water in the insulation
- Parts of the roof covered by fixed equipment
If in doubt, phone 07833 053749 or use the contact form and we’ll point you to the right survey. What our survey covers.
What this survey covers
- Green roofs
- Single-ply roofs

Flat and commercial roofs around Twyford
Thatch survives on some older buildings in Hampshire’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 normally a flat roof somewhere, whether on an extension, a garage or a commercial unit. An older home may be listed, or stand in a conservation area. Historic England’s list shows listed buildings, and the council can say whether a street is in a conservation area. Re-roofing in different materials may need permission there.
For site and facilities teams at buildings such as Twyford St Mary's Church of England Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. For landlords with property near Shawford station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
