Electronic leak detection for homes and businesses in Alverstone
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It works with an electrical current that passes through the membrane only where there’s a breach. That lets us locate holes that are too small to see, so your roofer can repair them. You get a report with photographs of each breach found. If you are worried about leaking laps in the waterproofing and water coming in under a flat roof, we can find out what’s behind it, on flat roof membranes, green roofs and liquid-applied waterproofing alike.
In a small place like Alverstone, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Felt roofs, which frequently last around 15–20 years, normally show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are usually the first part of a flat roof to go.
Where we can’t see part of the flat roof membrane, the report says so. That way, it’s clear what was covered and what wasn’t, and what we’d suggest next.

What else we do in Alverstone
Why act early in Alverstone
Not every leak is in the membrane. Testing shows whether the membrane is breached, so other causes can be checked. Where a roof is exposed, as many are in small places like Alverstone, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the price for your roof before booking.
Why book with us
- Thermal imaging and drone inspection where they help
- Drone flown under a CAA Flyer ID and Operator ID
- Surveys on weekdays, Saturdays and Sundays
- Satisfaction rate of 98%

How it works
We will ask a few questions first, about the roof’s history, any leaks and past repairs. Then the inspection itself takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. In a small place like Alverstone, access is typically the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
How to prepare
- Tell us where we can park nearby
- For a flat or shared roof, check access with whoever owns or manages the building
- Unlock side gates and any roof access doors
Arrange a survey
A quick phone call is usually the easiest start: phone 07833 053749 or use the contact form and we will ask a few questions about the roof. The price is agreed before a date is set.
Advice
When to book a survey in Alverstone
New membranes can have defects from installation. Testing before the roof is covered or handed over helps find them.
People typically book a survey after spotting one of these:
- Leaks under green or ballasted roofs
- Stains far from any visible defect
- A flat roof leak that cannot be traced
- Leaks that return after repairs
If yours is one of the older homes in the streets near All Saints' Church, the flat roofs on later extensions tend to wear out long before the main roof.
Choosing a roof surveyor
- Will the report include photos?
- What experience they bring
- Is there a chance to talk the report through?
- What they will not be able to tell you
What electronic leak detection looks like in Alverstone
The coast is about 2 miles or less from Alverstone, and places near the sea get more salt in the air and more wind than inland. Wind can catch loose edges and trims on a flat roof, and salt air is hard on metal trims, flashings and fixings. About 1.8 miles west lies Haseley Manor, a reminder of how long the area around Alverstone has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area.
If you let a flat or house near Sandown station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. Anyone responsible for a site like Newchurch Primary School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Prices for electronic leak detection in Alverstone
Every roof is different, so prices are confirmed before you book. This is what makes a difference:
- The roof’s overall size
- How complicated the roof is, with its valleys, chimneys and parapets
- The type of building, from a house to a block or an office
- The use of thermal imaging or a drone
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.
What to let us know when you contact us
We will typically ask about:
- Where the property is, with the postcode
- Your timetable, like an exchange date
- How the loft is reached, if there is one
- Any marks or damp showing indoors
Getting a price is simple: just ring 07833 053749 or drop us an email, let us know about the property and we will suggest the right survey. The price is agreed up front.
Your questions about electronic leak detection in Alverstone
Do you cover smaller places like Alverstone?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Is my home in Alverstone 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.
How many surveys have you done?
We have more than 20 years’ experience and have carried out more than 5,000 surveys.
Can you tell me if my roof has asbestos?
No. We can flag materials that might contain asbestos, but only a specialist asbestos surveyor can confirm it. Buildings built or refurbished before 2000 may contain it.
Which days do you carry out surveys?
Surveys run seven days a week. To arrange a date, phone 07833 053749 or use the contact form.
Does someone need to be in?
It depends on what we need to see. For inside areas and the roof space, someone has to give us access.
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. For a quote, call 07833 053749 or send us an email.
Should I look at the roof myself first?
Your own check is a good start, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are frequently out of sight.
What you cannot do safely is get up close. Roofs are fragile and slippery. That part is for a survey.
