Electronic leak detection in Cowes, Isle of Wight
Not sure what state the flat roof membrane is in? We carry out electronic leak detection in Cowes and across the Isle of Wight, with plain-English findings.
- Breaches around outlets and penetrations
- Leaks showing away from the breach
- A flat roof leak that can’t be traced
Useful tips for Cowes property owners
A few practical points come up again and again on our surveys. They apply to most roofs:
- Record dates and spots where water appears
- Find the breach before more patching
- Test new membranes before covering them
- Make sure trades protect the waterproofing
If we think the leak isn’t coming through the membrane, the report says so, so other causes can be checked.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.
About our electronic leak detection in Cowes
Green roofs, ballasted roofs and roofs under paving are harder to test. The layers on top can limit the methods we can use, and some may need lifting. We will discuss it with you when we quote. Any details of the build-up help, as they show what lies beneath the surface. If testing isn’t possible, we’ll say so. Typical surveys look at holes left by work on the roof and stains far from any visible defect, across single-ply roofs, flat roof membranes and commercial flat roofs.
In a town like Cowes, flat roofs are common on rear extensions, garages, porches and dormers. Many are felt, and newer ones may be EPDM rubber or GRP. Ponding water, splits along the edges and lifting upstands are the usual warning signs. Standing water days after rain often shows a flat roof needs attention.
The report works through the roof section by section, from the coverings down to the gutters, each with a short note and a photo. It records what’s sound as well as what is not.

What happens if roof problems are left?
Repeated call-outs for the same leak add up. A clear record of where the breaches are helps break that cycle. Around Cowes, water from a roof defect often goes unseen for a while, soaking loft insulation, wall tops and timbers. By the time a stain appears on a ceiling, there is more to put right.
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the price for your roof before booking.

Local flat roofs in Cowes
The coast is about 2 miles or less from Cowes, and places near the sea get more salt in the air and more wind than inland. Coastal wind works at the edges of flat roofs, and salt air wears metal trims and fixings. Thatch survives on some older Isle of Wight buildings, and the whole island is open to sea air and wind. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
Historic houses like Osborne House, about 1.7 miles east, show how far back building around Cowes goes. If your home is older, its flat-roofed extension or dormer may be on its second or third covering. Hotels and guest houses near Cowes cannot easily close rooms for a leak. For an older house near a landmark such as St. Faith's Church, the joins between later flat roofs and the old walls are where problems typically start.
Cowes is about 8 miles south-west of Gosport, in the Isle of Wight. Anywhere in Cowes, we can come and survey your property, on a weekday, Saturday or Sunday.

What we do, step by step
The aim of the visit is simple: to look at the flat roof membrane as closely as is safe and record what we find. Notes and photos go into the written report. It normally takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. A survey in Cowes needs access inside and out, including the loft hatch and any rooms with damp. Mention gates, side passages and anything at the back. Weekday and weekend visits are available.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- 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 photos in a report for your roofer.
Preparing for the visit
- Clear the way to the loft hatch
- Let us know about parking near the property
- Keep pets out of the way during the survey

Prices for electronic leak detection in Cowes
Prices vary from roof to roof, and it comes down to:
- The use of thermal imaging or a drone
- How tall the building is and how easy the roof is to see
- Extra roofs, like extensions, dormers or garages
- Commercial roofs and larger buildings
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You’ll know the figure before booking.
What to tell us when you contact us
These details help when you get in touch:
- Your postcode, so we can check access and travel
- Anything about access we should know
- Any stains, drips or damp patches you’ve seen indoors
- Why you want a survey: buying, a leak, a storm or new work
We survey roofs seven days a week. To arrange a day that suits you, phone 07833 053749 or send us an email.
Honest limits
No survey can tell you everything, and it is better to know them up front. Bear these in mind:
- Moisture spread under the membrane
- Build-ups without a suitable layer below
- Areas we can’t reach or that cannot be tested
If in doubt, call 07833 053749 or email us and we will recommend the right survey. What a survey covers and doesn’t.
What this survey covers
- Green roofs
- Liquid-applied waterproofing
- Flat roof membranes
- Commercial flat roofs
- Roof terraces and balconies
- Single-ply roofs
Can I check my roof myself?
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
What you cannot do safely is get up close. Roofs are fragile and slippery, and a fall can be serious. That’s where a survey comes in, using safe viewpoints and a drone where it applies.
FAQs for Cowes
Does a conservation area affect roof work in Cowes?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Do roofs near the sea, like those around Cowes, take more of a battering?
Frequently, yes. Cowes is within about 2 miles of the sea, and coastal roofs tend to see faster wear on metal parts and more wind lifting loose pieces.
Do you work in Cowes?
Yes. Cowes is part of the area we cover, and the service is the same as everywhere else we work.
How much does electronic leak detection cost?
Each roof is quoted on its size and build-up. Tell us about the roof and where it leaks. Just phone 07833 053749 or send us an email for a quote.
Do you climb onto every roof?
Not always. Safety comes first, and fragile or steep roofs can’t always be walked on. We use safe viewpoints, the roof space and a drone where it applies.
How long will testing take?
The roof’s size and build-up decide how long it takes. We will give you an idea when we quote.
How experienced are you?
We have more than 20 years’ experience and have completed over 5,000 surveys across London and the South East.
