Your questions about electronic leak detection in West Liss
Do you carry out roof surveys in West Liss?
Yes. We survey roofs across London and South East England, and West Liss is part of that. You can call 07833 053749 or email us with the address and some details.
Is West Liss within the area you cover?
Yes, West Liss is on our map. A small place gets exactly the same survey as a big one.
Does someone need to be in?
Not necessarily. If we only need the outside, we can agree that ahead of time, but the loft and any rooms with damp need someone to let us in.
How much does electronic leak detection cost?
Electronic leak detection is quoted for your roof, because the method depends on the roof. The price depends on the roof’s size and build-up. To get a quote, ring 07833 053749 or use the contact form.
What will the report tell me?
It explains what we saw, what it means and what we’d suggest, backed by photographs. Anything we couldn’t see safely is noted too.
Does the report include photos?
Yes. Photographs are taken throughout the survey, and they go into the written report alongside our recommendations.
Is this an asbestos survey?
No. Our report may flag materials that could contain asbestos, but confirming it is a job for a specialist asbestos surveyor. It may be present in buildings built or refurbished before 2000.
Electronic leak detection in West Liss
ELD finds breaches in the membrane, not every cause of water getting in. Water coming through walls, copings, rooflights or plumbing won’t show on the test. If the evidence points elsewhere, we will say so. The test shows breaches in the membrane, not water coming through masonry or around frames. The report makes clear what was and wasn’t tested. You’ll also know what to check next. Common reasons to book are leaks showing away from the breach and waterproofing to test before it’s covered, across roof terraces and balconies, green roofs and single-ply roofs.
In a small place like West Liss, a flat roof can stand in the open, so edges, upstands and laps take a beating. 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. Exposed edges are normally the first part of a flat roof to go.
Every survey ends with a written report, with photos, sent by email. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

Flat roofs in West Liss
A number of Hampshire villages keep thatched roofs on their older buildings. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. Before planning roof work on an older home, find out whether it’s listed or in a conservation area. Changes that affect a listed building’s special interest need listed building consent, and councils can also use Article 4 directions to control changes in conservation areas.
Landlords with a home close to Liss station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak. The streets around a church such as Church of St Mary are frequently among the oldest in a place, and if your home is one of the older ones nearby, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. For site and facilities teams at buildings like Liss Infant School, a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail.

What we do, step by step
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. In total, it takes as long as needed for the roof’s area and construction, which we set out in the quote. Somewhere as small as West Liss, access is often the only tricky part. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
- You let us know about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photos shows where each breach is.
Preparing for the visit
- Tell us about any leaks, stains or damp patches you know of
- Make sure pets are kept safely away
- Leave side gates unlocked
Book a survey
Photos help, if you have them. Take them safely from the ground or a window, and please don’t climb up for a closer look. To get started, ring 07833 053749 or email us.
Advice
Landlords, agents and block managers in West Liss
An agent can book and manage the survey for a landlord, with the report sent to whoever needs it. Access is agreed with the tenant beforehand.
Businesses and commercial landlords can book us too. Bigger roofs take more time.
How the survey changes by roof type
Bituminous membranes
ELD is often possible on bituminous membranes though the layers below matter.
Green and ballasted roofs
Parts of the covering may have to come up. We discuss this before quoting.
Useful tips for West Liss property owners
Here are a few things we’d tell any owner, before and after a survey:
- Stay off the flat roof unless needed
- Check new waterproofing before handover
- Act on new leaks promptly
- Note where leaks show inside and when
If water has been getting in, insulation under the membrane may be wet. That’s something to discuss with your roofer, and moisture readings can help.
Don’t leave a flat roof leak running. Water under a membrane can spread.
How we price electronic leak detection
When we price a survey, we consider:
- The number of roofs, including extensions and garages
- How tall the building is and how easy the roof is to see
- Whether thermal imaging or a drone is needed
- Features like valleys, chimneys, dormers and parapets
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You’ll know the figure before booking.
Getting in touch
The more you let us know, the easier it is to price the survey. When you contact us, let us know:
- Pictures from the garden or a window, if you have them
- Where the property is, with the postcode
- What’s prompted the survey
- How the loft is reached, if there is one
Booking is simple: just ring 07833 053749 or use the contact form, let us know about the property and we’ll explain which survey suits. The price is agreed up front.
What electronic leak detection doesn’t cover
A survey is a careful look at the flat roof membrane, but it can’t do everything. The main limits are:
- Fixing the holes we find
- Parts of the roof covered by fixed equipment
- Moisture spread under the membrane
