Electronic leak detection in Long Sutton
ELD suits many waterproofing membranes on flat roofs over offices, units, blocks of flats and homes. It can be used to trace an existing leak or check a new membrane before handover. 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 new membranes needing a check before handover and leaks through a flat roof with no obvious cause, we can find out what’s behind it.
Somewhere as small as Long Sutton, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. We simply plan the journey and access in advance. If there are outbuildings or garages with flat roofs, mention them when booking.
The report does not just list problems. For each finding, it explains what it is, why it matters and what we’d recommend.

Why act early in Long Sutton
Leaks left running can wet the insulation and deck. Locating it early helps limit the damage. Older cottages and farmhouses around Long Sutton can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it’s left.

The survey, step by step
Photos are taken throughout the visit, so you can see in the report what we found and where. We take close-ups from wherever is safe. Most surveys take more time on a big roof than a small one, and the build-up of the roof makes a difference too. Around Long Sutton, older homes can have small or awkward roof spaces, so it helps to know whether there’s a loft hatch and how easy it is to reach. We only go where it’s safe.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We confirm whether the roof is suitable for electronic testing.
- We pick the low-voltage or high-voltage method that suits the roof.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
Before we arrive
- If it is not your property yet, arrange access through the agent
- Make a note of anything you’d like us to look at
- Leave a clear route to the loft

Electronic leak detection around Long Sutton
Some Hampshire villages still have thatched roofs. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. If your home is older, it’s worth knowing whether it is listed or in a conservation area before planning roof work. Listed building consent covers changes to a listed building’s special interest, and an Article 4 direction can bring extra controls in a conservation area.
For landlords with property near Bentley (Hampshire) station, the flat roof over a let home is worth a look before it becomes a tenant complaint. If your house is among the older ones in the streets near Church of All Saints, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

Do you need electronic leak detection in Long Sutton?
Water travels under flat roof membranes. The leak may show some distance from where water gets in, so tracing it by eye is difficult.
Problems we come across often include:
- Waterproofing to test before it’s covered
- Leaks showing away from the breach
- Punctures from foot traffic or tools
- Breaches around outlets and penetrations
If you look after a building such as Long Sutton Church of England Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Before booking any roof surveyor

- How much experience they have with roofs like yours
Tips from our surveys
You do not need to be a roofer to help. What helps most:
- Limit access to the roof
- Let us know about the membrane and build-up if you know it
- Clear flat roof outlets regularly
- Find the breach before more patching
File the report with your roof paperwork. It shows the condition of the membrane on that date.
Don’t leave a flat roof leak running. Water under a membrane can spread.
Should I look at the roof myself first?
A lot can be seen from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please don’t climb up for a closer look.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, as it helps a surveyor trace the cause.
How the survey changes by roof type
Liquid-applied waterproofing
Small holes in liquid waterproofing may leak. Where the roof suits it, testing can find them.
Inverted and paved roofs
On inverted roofs, insulation sits above the membrane and that changes how testing works.
Your questions about electronic leak detection in Long Sutton
Will you come out to Long Sutton?
Yes, Long Sutton is covered. We work right across London and South East England, and smaller places are part of that. Longer journeys are simply planned in advance.
Does a conservation area affect roof work in Long Sutton?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
How much time does ELD need?
It typically takes longer on a large roof than a small one, with the construction of the roof playing a part too.
How much does electronic leak detection cost?
We quote electronic leak detection for each roof, as the method and time depend on the roof. The price depends on the roof’s size and build-up. To get a quote, ring 07833 053749 or email us.
Does the weather affect the survey?
Some surveys depend on the weather more than others. Drone flights need calm, dry weather, and thermal imaging works best after a sunny day, with a dry roof and little wind. If the conditions are not right, we will talk to you about another date.
Can every flat roof be tested?
ELD doesn’t suit every roof. Some membranes conduct electricity, and some build-ups lack a suitable layer below. If your roof will not work, we will say so at the start.
Do you carry professional indemnity insurance?
We hold professional indemnity and public liability insurance.
