How electronic leak detection works in Cranmore
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small electrical current that passes through the membrane only where there is a breach. It can find holes too small to spot by eye so your roofer knows exactly where to repair. You get a written report with photos of each breach found. We survey green roofs, roof terraces and balconies and single-ply roofs, and the problems we are asked to look at most are damage from equipment installers and leaks that return after repairs.
In a village or hamlet like Cranmore, flat roofs are usually on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: outlets, upstands, edges and the covering itself. We simply plan the journey and access in advance. Garages and outbuildings are easy to forget, so mention any you want included when you book.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. You will know exactly what was inspected and what wasn’t.

Tips from our surveys
Over many surveys, some simple habits stand out:
- Share any drawings of the roof
- Check new waterproofing before handover
- Keep foot traffic on flat roofs to a minimum
- Find the breach before more patching
File the report with your roof paperwork. It shows the condition of the membrane on that date.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.
What else we do in Cranmore
How we price electronic leak detection
The price reflects the time and kit the roof needs. That comes down to:
- Building height and the viewpoints available
- The roof’s overall size
- The shape of the roof and its details
- Extra roofs, like extensions, dormers or garages
For a price for your roof in Cranmore, phone 07833 053749 or drop us an email with the address and some details. The price is agreed before a date is set.
Helping us price your survey
When you call or email, these details help:
- Anything about access we should know
- The property’s address and postcode
- Pictures of the roof from a safe spot, if you have them
- What made you get in touch
We confirm the price for your roof before you book, so you know where you stand. We quote electronic leak detection for each roof, as the method and time depend on the roof. For a price for your roof, call 07833 053749 or use the contact form.
Checking the roof from ground level
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it.
Your own check is a good start, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are frequently out of sight, and those are details a survey looks at closely.
Roof by roof
EPDM rubber roofs
ELD on EPDM depends on the product and the layers. We check this first.
Liquid-applied waterproofing
What lies under a liquid coating decides if ELD will work.
Common questions in Cranmore
Is Cranmore within the area you cover?
Yes, we do. We survey roofs across London and South East England, and smaller places are part of that. The journey is planned ahead, so it is useful to know about access.
Does being near the coast affect roofs in Cranmore?
Generally, yes: wind and salt air take more of a toll near the sea. Ridges, verges, flashings and fixings are where it usually shows.
Do you need to get into the loft?
If there’s a loft and safe access to it, yes. The roof space can show things the outside can’t, like damp timbers, staining or daylight.
Is this an asbestos survey?
No. We can flag materials that might contain asbestos, but only a specialist asbestos surveyor can confirm it. It may be present in buildings built or refurbished before 2000.
What do I do with the report?
The report comes by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Does ELD include fixing the breach?
No, our part is finding the breaches. Your roofer uses the report to target the repair.
Can you survey at the weekend?
Visits run seven days a week in the daytime. Let us know your preferred days when you book.
Why get it checked now?
Some breaches are too small to see. Electronic testing can find breaches you cannot see by eye, on suitable membranes. For an older or listed building in a place like Cranmore, repairs may need matching materials and consent, so leaving a defect until it’s urgent leaves less time to plan.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You will know the figure before booking.

What electronic leak detection looks like in Cranmore
The coast is about 1 mile or less from Cranmore, so there is more wind and more salt in the air than further inland. Wind can catch loose edges and trims on a flat roof, and salt air is hard on metal trims, flashings and fixings. About 3.4 miles south-east lies Swainston Manor, a reminder of how long the area around Cranmore has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs.
Landlords with a home close to Lymington Pier station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round. Anyone responsible for a site like Shalfleet Church of England Primary School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Cranmore is about 6 miles south-east of Lymington, in the Isle of Wight. Cranmore is part of the area we cover and the surrounding area across London and South East England. Cranmore is one of the places in the Isle of Wight where we work. We also survey roofs in Southampton.

The survey, step by step
On the day, we begin with a quick chat about the roof and anything that’s worrying you. We then inspect everything that can be seen safely. Most surveys take longer on a large roof than a small one, and the build-up of the roof makes a difference too. Somewhere like Cranmore needs a little journey planning: let us know about lanes, gates and parking. 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 agree the area to be tested.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Before the survey
- Keep pets out of the way during the survey
- Make a note of anything you’d like us to look at
- Agree roof access with the managing agent if it is shared
