Warsash Electronic Leak Detection
A careful look at the flat roof membrane at your property in Warsash, with photos and a written report.
- Holes around roof penetrations
- New membranes needing a check before handover
- Leaking laps in the waterproofing
Roof by roof
Liquid-applied waterproofing
Pinholes in a coating can let water through. Where the roof suits it, testing can find them.
Green and ballasted roofs
Green roofs and ballasted roofs cover the waterproofing. Some methods can work through these layers, depending on the build-up.
Electronic leak detection in Warsash
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It works with an electrical current which can only get through the membrane at a breach. It can find holes too small to spot by eye so your roofer knows exactly where to repair. The results come in a report with photos. If you’re worried about damp inside with no sign on the roof and breaches hidden under paving or planting, a survey will tell you what’s going on.
Around Warsash, many homes have a garden room, garage or outbuilding with a flat roof. 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 as you book, 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.
We write the report in plain English, so it makes sense without any roofing background. Photographs show what each point refers to, with the urgent items made clear.

Why get it checked now?
Testing a new membrane before it is covered is easier than tracing a leak later. Once layers are added, finding a breach is harder. Homes in smaller places like Warsash can face more weather, so a loose ridge or verge soon lets rain in. Wind gets under it and lifts more.

Electronic leak detection in Warsash: local notes
Warsash lies within about 2 miles of the sea, where sea air brings more salt and stronger wind than inland. On a flat roof near the sea, edge trims and upstands take the brunt of the wind, and metal parts corrode faster. If your home is older, it’s worth knowing whether it’s 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.
Take a building like Hook-With-Warsash Church of England Academy: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. For an older house near a landmark such as Church of St Mary, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear.

How we price electronic leak detection
What a survey costs depends on the time and equipment it needs. The main factors are:
- Features like valleys, chimneys, dormers and parapets
- Extensions, dormers and garages with roofs of their own
- Building height and the viewpoints available
- The roof’s overall size
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You will know the exact price before booking.

Do you need electronic leak detection in Warsash?
Water travels under flat roof membranes. The leak may show some distance from where water gets in which makes it hard to find by looking.
Most people get in touch when they’ve noticed something like this:
- Stains far from any visible defect
- Water coming in under a flat roof
- Leaks under green or ballasted roofs
- Punctures from foot traffic or tools
For landlords with property near Swanwick station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Questions to ask before booking
- Are they insured for the work?
- Is there a chance to talk the report through?
- Whether VAT is added on top
- What’s outside the scope of the survey
Other services in Warsash
Checking the roof from the ground
What you cannot do safely is get up close. Roofs are fragile and slippery. That’s where a survey comes in.
A DIY look is useful, but it isn’t a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground.
FAQs for Warsash
Is the coastal weather around Warsash hard on roofs?
Yes, coastal weather is harder on roofs: there’s more wind, and more salt in the air. Exposed details such as ridges, verges, flashings and metal fixings are the ones to watch, and Warsash is within about 2 miles of the coast.
Is my home in Warsash listed or in a conservation area?
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?
Each roof is quoted on its size and build-up. Tell us about the roof and where it leaks. Just ring 07833 053749 or drop us an email for a quote.
Are you insured?
Our surveys are covered by professional indemnity and public liability insurance. Ask if you need details for a managing agent or building owner.
Is this an asbestos survey?
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.
Can you survey a shared roof?
Yes, as long as access is agreed. The roof of a block or converted house is often shared, so whoever owns or manages the building needs to agree access. We can only inspect what we’re given access to.
Is Warsash in your area?
Yes. We cover Warsash and the rest of Hampshire. To book, ring 07833 053749 or use the contact form.
The survey, step by step
The visit has one job: to see as much of the flat roof membrane as can safely be seen and record it clearly. Everything we note and photograph goes into the written report. The visit usually takes a length of time set by the roof’s area and construction, which we’ll explain when we quote. A visit to a smaller place like Warsash is no different on the day: outside, inside and from any safe vantage point, in that order. Point out any stains, cracks or loose pieces you’ve spotted.
- First, you let us know about the roof build-up and where water is showing.
- We check that the membrane and build-up suit electronic leak detection.
- We pick the low-voltage or high-voltage method that suits the roof.
- Testing runs across the roof to locate breaches in the membrane.
- The breaches are recorded with photos in a report for your roofer.
Before we arrive
- Have any paperwork from past roof work to hand
- Check we can get to the back of the property
- Note where any stains or damp appear
