Electronic leak detection in Liss, Hampshire
Electronic leak detection in Liss, with over 20 years’ experience behind it. Every survey ends with a written report and photographs.

- Leaks through a flat roof with no obvious cause
How electronic leak detection works in Liss
Not every flat roof suits electronic testing. Certain membranes conduct electricity, and some build-ups lack the layer the test needs below the membrane. If your roof is not suitable, we’ll tell you at the start. Any details you have about the membrane and build-up help us decide, such as drawings or specifications. It saves a wasted visit. If you’re worried about punctures from foot traffic or tools and leaks under green or ballasted roofs, we can find out what’s behind it, on commercial flat roofs, green roofs and liquid-applied waterproofing alike.
Outbuildings, garden rooms and garages in places like Liss often have flat roofs of their own. They’re easy to forget, but water through a garage roof can spoil whatever is stored inside. If you want them looked at too, mention them when booking, along with the main flat roof. Smaller roofs use the same coverings as bigger ones, from felt to rubber and GRP, and age in the same way.
It isn’t only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend.

Tips that help
A survey works best with a little help from you, before and after. Some tips:
- Stay off the flat roof unless needed
- Share any drawings of the roof
- Find the breach before more patching
- Clear flat roof outlets regularly
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
Consider testing a new membrane before it is covered. Finding breaches is simpler at that stage.

Your questions about electronic leak detection in Liss
Is Liss in the area you cover?
Yes, Liss is within the area we cover. Our area covers London and South East England. Just call 07833 053749 or send us an email and let us know about the property.
How do I find out if my home in Liss is listed?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
How is ELD priced?
We quote for each roof individually. Send us details of the roof, and call 07833 053749 or send us an email for a quote.
How do I arrange electronic leak detection in Liss?
Just ring 07833 053749 or send us an email. We will ask a few questions, confirm the price and agree a date.
Does electronic leak detection work on all membranes?
ELD doesn’t suit every roof. Some membranes conduct electricity and some roofs lack the layer the test needs. We will tell you if yours isn’t suitable before testing.
Does the weather affect the survey?
It depends on the weather and the survey. Strong wind or a downpour can make access unsafe and ground a drone, so we’d move the date with you.
Will you fly a drone over my roof?
Yes, where it is applicable. Flights depend on the weather on the day and airspace rules, including flight restriction zones near airports. We are a CAA-registered drone operator.
Local flat roofs in Liss
What can be done to an older roof may depend on listing or a conservation area. Your council and Historic England’s list will tell you where you stand. 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. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
For site and facilities teams at buildings like Liss Infant School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If you own one of the older houses in the streets near Church of St Mary, flat-roofed rear additions and dormers added over the years are worth checking. Landlords with a home close to Liss station may find that the flat roof over a let home is worth a look before it becomes a tenant complaint.

What we look for on each type of roof
EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but can still be punctured.
Bituminous membranes
Bituminous roofs frequently have laps and old repairs that can leak. Testing depends on the roof.
Leave it or get it looked at?
Leaks left running can wet the insulation and deck. Finding the breach sooner limits that. Homes in smaller places like Liss can face more weather, so a loose ridge or verge soon lets rain in. Each storm lifts it a little further.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before booking.

Read how roof surveys are priced and two real surveys.
What happens on the day
We photograph the roof as we go, so you can see in the report what we found and where. We take close-ups from wherever is safe. A typical visit takes a time that depends on the membrane area and the build-up, which we set out in the quote. A visit to a smaller place like Liss is no different on the day: we look from the ground, from windows, from the loft and from the roof where it is safe. Point out any stains, cracks or loose pieces you’ve spotted.
- We start by finding out what the roof is made of and where it leaks.
- We check that the membrane and build-up suit electronic leak detection.
- The testing method is chosen to suit the membrane and build-up.
- Testing runs across the roof to locate breaches in the membrane.
- The breaches are recorded with photographs in a report for your roofer.
Before the survey
- Note where any stains or damp appear
- Unlock side gates and any roof access doors
- Keep pets inside or away from the areas we are looking at

What affects the cost of electronic leak detection
What a survey costs depends on the time and equipment it needs. The main factors are:
- Commercial roofs and larger buildings
- Extensions, dormers and garages with roofs of their own
- Whether thermal imaging or a drone is needed
- The shape of the roof and its details
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You’ll know the price for the job before you book.
Getting in touch
To price your survey accurately, we will ask about:
- Any deadline, like an exchange date
- What kind of property and roof it is
- Whether there is a loft hatch, a shared roof or tricky access
- Where water is showing inside, if it is
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, phone 07833 053749 or email us.
