EPDM rubber roofs
ELD on EPDM depends on the product and the layers. We check this first.
Electronic leak detection in Sparsholt
Not every flat roof suits electronic testing. Certain membranes conduct electricity and some roofs do not have a suitable layer beneath the membrane. If your roof isn’t suitable, we will 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 single-ply roofs, commercial flat roofs and green roofs, and the problems we’re asked to look at most are punctures from foot traffic or tools and leaks that return after repairs.
In a small place like Sparsholt, a flat roof can stand in the open, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, typically 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 written report with photos, emailed to you. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

What else we do in Sparsholt
Why get it checked now?
Testing a new membrane before it is covered is easier than tracing a leak later. Once layers are added, finding a breach is harder. In a small place like Sparsholt, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Questions from Sparsholt
Is Sparsholt in the area you cover?
Yes. We cover the whole of London and South East England, and Sparsholt is part of that. You can call 07833 053749 or use the contact form with the address and a few details, and we will talk through which survey suits.
Will you come out to Sparsholt?
Yes, smaller places are covered as well as towns. We cover the whole of London and South East England. Just mention lanes, gates or anything else about the route when you book.
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 will not work, we’ll say so at the start.
How many surveys have you done?
More than 5,000 surveys over 20+ years, across London and South East England.
Does someone need to be in?
That depends on the survey. For inside areas and the roof space, someone has to give us access.
What do I do with the report?
We email you the written report with photos and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Will you walk on the roof?
Only if it’s safe. We inspect what can be seen safely: from the ground, from windows, from inside the loft space, from the roof where it is safe and by drone where applicable. Anything we can’t see is noted in the report.
Common roof problems in Sparsholt
Holes in a membrane often come from feet, tools or debris. Many are tiny, but still let water through.
A survey makes sense if you’ve noticed:
- Patched roofs that still leak
- Damage from equipment installers
- A flat roof leak that cannot be traced
- Stains far from any visible defect
For site and facilities teams at buildings like Sparsholt Church of England Primary School, a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail.

Practical tips
A survey works best with a little help from you, before and after. Some tips:
- Use boards when working on the roof
- Test new membranes before covering them
- Avoid repeated repairs without finding the cause
- Tell us about the membrane and build-up if you know it
If water has been getting in, insulation under the membrane may be wet. Your roofer can advise on that and other checks can help judge it.
Consider testing a new membrane before it’s covered. Finding breaches is simpler at that stage.
How it works
We photograph the roof as we go, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available, including by drone where it is applicable and the weather allows. Most surveys take as long as needed for the membrane area and the build-up, and we’ll give you a guide when quoting. Somewhere like Sparsholt needs a little journey planning: let us know about lanes, gates and parking. On the day, we inspect what can safely be seen, inside and out.
- First, you tell us about the roof build-up and where water is showing.
- We check that the membrane and build-up suit electronic leak detection.
- We pick the low-voltage or high-voltage method that suits the roof.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photos in a report for your roofer.
Preparing for the visit
- If the roof is shared, arrange access with whoever manages the building
- Jot down any questions you want answered
- Check pets are kept safely away

Electronic leak detection around Sparsholt
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. In either case, a change of roofing material may need consent. A number of Hampshire villages keep thatched roofs on their older buildings. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For an older house near a landmark such as Church of St Stephen, 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 Winchester station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
