Upton Grey Electronic Leak Detection
Electronic leak detection to pinpoint holes in flat roof membranes for Upton Grey, from an experienced roof surveyor. Every survey comes with a written report and photographs.
- Water coming in under a flat roof
- New membranes needing a check before handover
- Leaks under green or ballasted roofs
How the survey changes by roof type
EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but punctures and seam failures still happen.
Inverted and paved roofs
Paving and terraces cover the membrane. Whether it can be tested depends on the build-up.
How electronic leak detection works in Upton Grey
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small electrical current which can only get through the membrane at a breach. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. The results come in a report with photos. If you’re worried about stains far from any visible defect and punctures from foot traffic or tools, we can find out what’s behind it, whatever the roof.
In a small place like Upton Grey, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Older felt roofs, frequently around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are usually the first part of a flat roof to go.
Nothing in the report is left vague: if work is needed, the report says so clearly.

Electronic leak detection in Upton Grey: local notes
Before planning roof work on an older home, find out whether it’s listed or in a conservation area. Changes that affect a listed building’s special interest need listed building consent, and councils can also use Article 4 directions to control changes in conservation areas. 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. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
If you own a rental within reach of Hook station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. Take an older house close to 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.

How it works
We work from the outside in: outside views come first, then the loft space if there is safe access. In total, it takes as long as needed for the membrane area and the build-up, and we’ll give you a guide when quoting. Somewhere like Upton Grey needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. The roof is looked at from the ground, from windows, from the loft where there’s safe access and from the roof where it is safe.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
Before we arrive
- Make a note of anything you’d like us to look at
- Tell us where we can park nearby
- Tell us about any leaks, stains or damp patches you know of

What happens if roof problems are left?
Water trapped under a membrane can soak insulation and decking. Finding the breach sooner limits that. Outbuildings and barns around Upton Grey are easy to forget, but a failed roof there can spoil what’s stored inside. It’s worth including them in a survey before a winter does the damage.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before you book.

Common questions in Upton Grey
Do you carry out roof surveys in Upton Grey?
Yes. We survey roofs across London and the South East, and Upton Grey is part of that. Just ring 07833 053749 or email us and let us know about the property, and we’ll talk through which survey suits.
Do you cover smaller places like Upton Grey?
Yes, Upton Grey is on our map. A small place gets exactly the same survey as a big one.
Does this replace a RICS home survey?
No. We check the roof, not the whole building, so it’s not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
How much time does ELD need?
Testing normally takes more time on a big roof than a small one, with the construction of the roof playing a part too.
What does the report include?
It explains what we saw, what it means and what we’d suggest, with photos throughout. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
Does ELD include fixing the breach?
No, our part is finding the breaches. Your roofer uses the report to target the repair.
What if it rains on the day?
It depends on the weather and the survey. High wind or heavy rain can make access unsafe and ground a drone, and we’d agree another day.
What this survey can’t tell you
It is useful to know what a survey won’t do before you book:
- Roofs whose membrane or build-up is not suitable
- Fixing the holes we find
- Water entering through details rather than the membrane

Helping us price your survey

What you can safely check yourself
A lot can be seen from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
Look up at the roof after a storm, from the ground: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
