Sandown Electronic Leak Detection
Know where you stand with the flat roof membrane before you spend money on it. We carry out electronic leak detection in Sandown, with photos and a clear written report.
- Stains far from any visible defect
- Leaks at pipes, outlets or fixings
- Repairs that haven’t stopped the leak
Why get it checked now?
Water trapped under a membrane can soak insulation and decking. Locating it early helps limit the damage. In a smaller place like Sandown, wherever a roof is exposed, a loose ridge or flashing does not stay loose for long. Each storm lifts it a little further, and water follows.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.
Why choose Independent Roof Survey in Sandown

Electronic leak detection for homes and businesses in Sandown
Some flat roofs cannot be tested electronically. Certain membranes conduct electricity and some roofs don’t have a suitable layer beneath 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, including drawings, specifications or the roofer’s paperwork. It avoids arranging a test that can’t give results. We survey commercial flat roofs, single-ply roofs and flat roof membranes, and the problems we are asked to look at most are leaks through a covered membrane and a flat roof leak that can’t be traced.
Around Sandown, many homes have a garden room, garage or outbuilding with a flat roof. They’re rarely looked at until something gets wet. It’s worth mentioning them as you book, so the visit can include them. Smaller roofs use the same coverings as bigger ones, from felt to rubber and GRP, and age in the same way.
It isn’t only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend.

Your questions about electronic leak detection in Sandown
Does a conservation area affect roof work in Sandown?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Is the coastal weather around Sandown hard on roofs?
Yes, coastal weather is harder on roofs: there is more wind, and more salt in the air. Exposed details such as ridges, verges, flashings and metal fixings are the ones to watch, and Sandown is within about 1 mile of the coast.
Does ELD work under paving or planting?
It can be possible, depending on the roof. Covered roofs limit the methods we can use so we check the roof first.
Is my roof suitable for ELD?
Not every roof is suitable. Certain membranes are conductive and some roofs lack the layer the test needs. We will tell you if yours is not suitable at the start.
How long have you been surveying roofs?
Over 20 years and more than 5,000 surveys, across London and South East England.
What insurance do you have?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
Do you use low-voltage or high-voltage testing?
The roof decides the method. You will know which method we plan to use before we start.
Practical tips
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Tips:
- Test new membranes before covering them
- Clear flat roof outlets regularly
- Ask contractors to protect the membrane
- Find the breach before more patching
If water has been getting in, insulation under the membrane may be wet. That is something to discuss with your roofer and other checks can help judge it.
Don’t leave a flat roof leak running. Water under a membrane can spread.
Local flat roofs in Sandown
Sandown is within about 1 mile of the coast, 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. The wider area around Sandown has a long history of building, with Morton Manor about 1.5 miles north-east. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
If you let a flat or house near Sandown station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. Take an older house close to Christ Church: flat-roofed rear additions and dormers added over the years are worth checking.

When to book a survey in Sandown
Other trades on the roof can puncture the waterproofing. Engineers fitting equipment, solar panels or aerials may leave damage behind.
Common reasons to book include:
- Leaks at pipes, outlets or fixings
- Holes left by work on the roof
- Patched roofs that still leak
- Leaks under green or ballasted roofs
Hotels and guest houses near Sandown can’t easily close rooms for a leak, so it pays to find faults before guests do.
Choosing a roof surveyor
- How soon the report will arrive
- How they plan to inspect the roof safely
- Whether VAT is added on top
- What exactly goes into their report
Rented homes, blocks and businesses
Letting agents can arrange access with tenants. Surveys run on weekdays, Saturdays and Sundays, which helps when tenants work during the week.
Roof problems in a rented home affect tenants as well as the building. A survey shows what needs attention, so you can plan the work.
DIY checks: what’s safe
During heavy rain, look at the gutters from the ground or a window. Overflowing water can point to a blockage or a sagging run.
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
How the survey works
There is not much for you to do on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we will get on with the inspection. The survey itself takes as long as needed for the roof’s area and construction, which we’ll explain when we quote. A visit to a smaller place like Sandown is no different on the day: outside, inside and from any safe vantage point, in that order. It’s useful to show us anything you’ve already noticed.
- We agree the area to be tested.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
How to prepare
- Find any records of previous roof work
- Buyers: confirm access with the estate agent or seller
- Make a note of anything you’d like us to look at
