Electronic Leak Detection in Cadnam
Electronic leak detection to pinpoint holes in flat roof membranes across Cadnam, with drones and thermal imaging where they help. Get in touch for a price.
- Leaks that return after repairs
- Leaking laps in the waterproofing
- Leaks through a flat roof with no obvious cause
Tips from our surveys
Here are a few things we’d tell any owner:
- Get leaks traced quickly
- Don’t keep patching the same spot
- Ask contractors to protect the membrane
- Consider ELD before paving or planting goes on
Wet insulation may need attention after a leak. Your roofer can advise on that, and moisture readings can help.
Do not leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
About our electronic leak detection in Cadnam
Electronic leak detection works on many flat roof membranes, on homes, blocks and commercial buildings. It helps trace a leak you already have or to test a new membrane before it’s covered. We quote for each roof based on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays, depending on the weather. Tell us about your roof to find out more. If you’ve noticed holes around roof penetrations and new roofs to check before paving or planting, a survey will tell you what’s going on, on green roofs, roof terraces and balconies and liquid-applied waterproofing alike.
In a small place like Cadnam, 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. Rubber and GRP last longer, though trims and joints still need a look. On an exposed roof, the edges tend to go first.
Nothing in the report is left vague: where something needs attention, it says so plainly, and where it can wait, that is said too.

Your questions about electronic leak detection in Cadnam
Will you come out to Cadnam?
We do. Villages and rural addresses get the same survey as a town house.
Is my home in Cadnam listed or in a conservation area?
We can’t confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Will I get photos?
Yes, plenty. Pictures sit next to the findings they show, so you can see what we mean.
Do you carry out surveys on Saturdays and Sundays?
Surveys can be booked for any day of the week: weekdays, Saturdays and Sundays. Tell us which days suit you when booking.
Can every flat roof be tested?
That depends on the roof’s membrane and layers. Share any details you have and we will confirm suitability.
What does electronic leak detection do?
It uses an electrical current to find breaches in a flat roof membrane. The current only gets through where the membrane is breached, which shows us where the hole is.
I live in a flat. Can you survey the roof?
Yes, if the freeholder or managing agent agrees access. We look at the parts we are given access to, and the report makes that clear.
Should I look at the roof myself first?
What you can’t do safely is get up close. Roofs are fragile and slippery, and falls from height are serious. That part is for a survey.
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Don’t go up yourself.
What affects the cost of electronic leak detection
When we price a survey, we consider:
- Chimneys, valleys, parapets and other details
- Extra roofs, like extensions, dormers or garages
- The size of the roof
- Any need for thermal images or a drone flight
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the price for your roof before booking.
Booking your survey
Here’s what helps us most when you contact us:
- The reason for the survey, such as buying, a leak or storm damage
- When you need the report by
- The kind of building and roof involved
- The property’s address and postcode
You can call us seven days a week. For a price or to book, ring 07833 053749 or email us.
How it works
When we arrive, we start by asking what you’ve noticed and what you’d like to know. After that, we check everything we can see safely. The survey normally takes a length of time set by the membrane area and the build-up, which we set out in the quote. Cottages and farmhouses around Cadnam often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints, and anything we cannot see is noted.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
How to prepare
- Have any questions written down, so nothing gets missed
- Dig out any old roof reports or invoices
- Tell us about parking before the day
How to book
We survey roofs on any day of the week. To arrange a day that suits you, call 07833 053749 or send us an email with the address and the days you’d prefer.
Related advice
What happens if roof problems are left?
A visual inspection can miss tiny holes. Electronic testing can find breaches you cannot see by eye, on suitable membranes. In a place like Cadnam, a barn or garage roof left to fail puts whatever is inside at risk. It’s worth including them in a survey before a winter does the damage.

Flat roofs in Cadnam
Cadnam lies within about 5 miles of the sea, and being near the sea means more wind and salt than a roof inland would face. Salt in the air is hard on metal flashings and fixings, and wind catches any loose edge on a flat roof. Historic houses like Landford Manor, about 4.6 miles north-west, show how far back building in the area around Cadnam goes. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material.
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. If you own a rental within reach of Ashurst New Forest station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

- Gaps at membrane joints

For site and facilities teams at buildings like Bartley Church of England Junior School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
