Electronic leak detection in Thorley, Isle of Wight
Electronic leak detection to pinpoint holes in flat roof membranes for Thorley, from an experienced roof surveyor. You get a clear written report with photos.
- Leaks showing away from the breach
- Leaks through a flat roof with no obvious cause
- Repairs that haven’t stopped the leak
What we are asked to look at in Thorley
A breach can be left during installation. Testing before the roof is covered or handed over helps find them.
Common reasons to book include:
- Leaking laps in the waterproofing
- Water coming in under a flat roof
- Leaks showing away from the breach
- Damage from equipment installers
Take an older house close to St. Swithin's Church: the flat roofs on later extensions tend to wear out long before the main roof.
What to check before booking
- How soon the report will arrive
- What exactly goes into their report
- Are they insured for the work?
- Whether VAT is added on top
How electronic leak detection works in Thorley
Not every flat roof suits electronic testing. Some membranes conduct electricity themselves, and some build-ups lack the layer the test needs below the membrane. We’ll say if ELD will not work on your roof at the start. Any details you have about the membrane and build-up help us decide, like drawings or specifications. It avoids arranging a test that can’t give results. Typical surveys look at new roofs to check before paving or planting and punctures from foot traffic or tools, on flat roof membranes, roof terraces and balconies and single-ply roofs.
Somewhere as small as Thorley, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them as you book.
After the visit, you get a photo-illustrated written report, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

Checking the roof from ground level
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That part is for a survey.
A lot can be seen from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
What happens if roof problems are left?
Not every leak is in the membrane. Testing shows whether the membrane is breached so attention can go to the right place. Matching old materials, like handmade tiles or stone slates, can take time to source. Spotting a problem early leaves room to find them.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
What you get with us

Questions from Thorley
Do roofs near the sea, like those around Thorley, take more of a battering?
Near the coast, roofs face more wind and more salt than further inland. Salt corrodes metal fixings and flashings, and wind lifts loose slates, tiles and ridge pieces.
Will you come out to Thorley?
Yes, Thorley is covered. We survey roofs across London and South East England, from towns to the smallest villages. The journey is planned ahead, so it helps to know about access.
What is electronic leak detection?
ELD passes a small electrical current across the roof to locate holes in the membrane. The current only gets through where the membrane is breached, which shows us where the hole is.
Do I have to be there for the survey?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you when booking.
Does ELD include fixing the breach?
No. We test the membrane and report. You get the breach locations with photos so your roofer can fix them.
Can you tell me if my roof has asbestos?
No. Our report may flag materials that could contain asbestos, but only a specialist asbestos surveyor can confirm it. It may be present in buildings built or refurbished before 2000.
Which days do you carry out surveys?
We survey seven days a week: Monday to Friday, Saturdays and Sundays. Tell us which days suit you when booking.
Prices for electronic leak detection in Thorley
When we price a survey, we consider:
- House, block, shop or office
- How many separate roofs there are, like extensions, dormers and garages
- Whether thermal imaging or a drone is needed
- Chimneys, valleys, parapets and other details
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You’ll know the figure before booking.
What to tell us when you get in touch
Getting the details right at the start saves time. Please include:
- Where any leaks, stains or damp patches show inside
- How the loft is reached, if there is one
- What made you get in touch
- The style of property, from a terrace to a block
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. Otherwise, simply call 07833 053749 or drop us an email whenever suits you.
What else we do in Thorley
What happens on the day
When we arrive, we start by asking what you’ve noticed and what you need to know. We then inspect everything that can be seen safely. Most surveys take a length of time set by the membrane area and the build-up, and we’ll give you a guide when quoting. Older roofs in small places like Thorley can have low, tight loft spaces, so it helps to know whether there is a loft hatch and how easy it is to reach. We only go where it’s safe.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photos shows where each breach is.
Before the survey
- Let us know about parking near the property
- Leave side gates unlocked
- Have any questions written down, so nothing gets missed
How to book
Photos help, if you have them. Take them safely from ground level or a window. To send them or to book, phone 07833 053749 or use the contact form.

Local flat roofs in Thorley
Thorley lies within about 2 miles of the sea, and places near the sea get more salt in the air and more wind than inland. Salt in the air is hard on metal flashings and fixings, and wind catches any loose edge on a flat roof. About 3.7 miles south-east lies Mottistone Manor, a reminder of how long the area around Thorley has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first.
Landlords with a home close to Lymington Pier station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
