Your questions about electronic leak detection in Osea Island
Is the coastal weather around Osea Island hard on roofs?
Places near the sea get more wind and more salt in the air than inland, and both are hard on roofs. Salt is hard on nails, clips and metal flashings, while strong wind lifts anything already loose.
How do I find out if my home in Osea Island is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
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. We will talk about access when booking.
How is ELD priced?
We quote for each roof individually. Send us details of the roof, and ring 07833 053749 or email us for a quote.
Will you check the loft?
If it’s needed and safe to reach, yes. Inside, we look for damp, staining, gaps and sagging.
Do you carry professional indemnity insurance?
Professional indemnity and public liability insurance cover our surveys. If you need details for a managing agent or a building owner, just ask.
How does ELD work?
A sound membrane blocks the test current, so wherever there is a hole, it passes through. That lets us find breaches that are too small to see.
Electronic leak detection in Osea Island: what you get
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small 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 written report with photos of each breach found. If you’ve noticed repairs that haven’t stopped the leak and breaches around outlets and penetrations, a survey will tell you what’s going on, whatever the roof.
Older buildings in small places like Osea Island may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you are planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Listed building consent is needed for changes that affect a listed building’s special interest.
Every survey ends with a written report, with photos, emailed to you. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

What a survey costs
To price your survey, we look at:
- Features like valleys, chimneys, dormers and parapets
- Height and safe access
- The roof’s overall size
- Any need for thermal images or a drone flight
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.
What to let us know when you contact us
Getting the details right at the start saves time. It helps to include:
- Pictures from the garden or a window, if you have them
- Any stains, drips or damp patches you’ve seen indoors
- The style of property, from a terrace to a block
- Why you want a survey: buying, a leak, a storm or new work
If you’re buying, it helps to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just ring 07833 053749 or email us when you are ready.
Checking the roof from the ground
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.
You can learn a lot 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 we do, step by step
Before we start, tell us why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. It helps us focus on what matters most to you. The visit usually takes a time that depends on the membrane area and the build-up, which we set out in the quote. In a hamlet or village like Osea Island, a postcode does not always lead to the right gate, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Preparing for the visit
- Make sure pets are kept safely away
- Show us where any leaks or stains appear
- Jot down any questions you want answered
Book a survey
Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, ring 07833 053749 or email us.
Advice
Rented homes, blocks and businesses
We also survey roofs for businesses and commercial landlords. Larger roofs take longer, so they’re priced to suit.
Letting agents and landlords in Osea Island book surveys as well as householders. The report gives you a dated record of the flat roof membrane, with photos, useful for planning maintenance.
Tips that help
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Keep foot traffic on flat roofs to a minimum
- Test new membranes before covering them
- Don’t keep patching the same spot
- Make sure trades protect the waterproofing
Where the evidence points to walls, copings or rooflights, we’ll note it, so other causes can be checked.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.
Electronic leak detection in Osea Island: local notes
The coast is about 2 miles or less from Osea Island, where sea air brings more salt and stronger wind than inland. Coastal wind works at the edges of flat roofs, and salt air wears metal trims and fixings. If your home is older, it’s worth knowing whether it is 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.
Around Osea Island, as everywhere, small roof faults are simplest to sort before they let water in. Wherever the property is around Osea Island, the approach is the same: a careful look and a clear explanation.

What happens if roof problems are left?
Repeated call-outs for the same leak add up. A report showing the breach points gives your roofer a clear target. Where a roof is exposed, as many are in small places like Osea Island, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You’ll know the figure before booking.
