Electronic leak detection for homes and businesses in Cottonworth
Some flat roofs cannot be tested electronically. Some membranes conduct electricity themselves, and some build-ups lack the layer the test needs below the membrane. We’ll say if ELD will not work on your roof at the start. Telling us what you know about the roof’s membrane and layers helps, including drawings, specifications or the roofer’s paperwork. It avoids arranging a test that can’t give results. If you’re worried about new roofs to check before paving or planting and leaks at pipes, outlets or fixings, a survey will tell you what’s going on, on flat roof membranes, green roofs and single-ply roofs alike.
Flat roofs on exposed homes in small places like Cottonworth take more wind and rain, 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.
The report records the flat roof membrane as we found it on the day. That makes it useful now and a handy reference later.

For landlords and managing agents

Your questions about electronic leak detection in Cottonworth
Do you cover smaller places like Cottonworth?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Is my home in Cottonworth listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you carry professional indemnity insurance?
We’re covered by professional indemnity and public liability insurance, for every survey we carry out.
Which days do you carry out surveys?
Surveys can be booked for any day of the week: weekdays, Saturdays and Sundays. Just tell us the days that suit you.
Can every flat roof be tested?
Not every roof is suitable. Some membranes conduct electricity and some roofs lack the layer the test needs. We’ll tell you if yours is not suitable before testing.
Can you inspect my roof with a drone?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and every flight depends on the airspace and the weather.
Can you test a green or ballasted roof?
Sometimes. The layers on top and the build-up below decide it, and some may need lifting. We talk this through first.
Local flat roofs in Cottonworth
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. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. England has around 10,000 conservation areas and about 500,000 listed buildings. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material, so the council is the place to ask.
If you let a flat or house near Andover station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. The streets around a church like Church of St Mary the Less are often among the oldest in a place, and if your house is among the older ones nearby, flat-roofed rear additions and dormers added over the years are worth checking.

What a survey costs
Not every roof costs the same to survey, for these reasons:
- The type of building, from a house to a block or an office
- Height and safe access
- The use of thermal imaging or a drone
- The number of roofs, including extensions and garages
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
Getting in touch
These details help when you get in touch:
- When you need the report by
- Pictures of the roof from a safe spot, if you have them
- Anything about access we should know
- Any stains, drips or damp patches you’ve seen indoors
A quick phone call is usually the easiest start: phone 07833 053749 or drop us an email and we will ask a few questions about the roof. You will have a price before anything is arranged.
What we do, step by step
There isn’t much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll take it from there. A typical survey takes as long as needed for the size of the roof and how it’s built, and we’ll give you a guide when quoting. Somewhere as small as Cottonworth, access is frequently the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
How to prepare
- Keep pets out of the way during the survey
- For flats, check roof access has been agreed
- If you’re buying, check with the agent that we can get in
Arrange a survey
Booking is simple: just ring 07833 053749 or use the contact form and give us a few details about the property and we will suggest the right survey. We confirm the price before anything is booked.

Useful tips for Cottonworth property owners
From years of surveys, a few habits stand out:
- Keep a note of leaks after rain
- Keep foot traffic on flat roofs to a minimum
- Get leaks traced quickly
- Keep outlets clear of debris
Wet insulation may need attention after a leak. That is something to discuss with your roofer and other checks can help judge it.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.

Bituminous membranes
Bituminous roofs often have laps and old repairs that can leak. Testing depends on the roof.
