How electronic leak detection works in Tapnage
Our ELD testing covers flat roofs in Tapnage and the rest of London and South East England. Testing typically takes a length of time set by the size of the roof and how it’s built, which we’ll explain when we quote. We quote electronic leak detection for each roof, as the method and time depend on the roof. The results come in a written report with photos. We survey flat roof membranes, liquid-applied waterproofing and commercial flat roofs, and people most frequently book us about leaks through a flat roof with no obvious cause and patched roofs that still leak.
Somewhere as small as Tapnage, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access ahead of time. If there are outbuildings or garages with flat roofs, mention them when booking.
Nothing in the report is left vague: if work is needed, the report says so clearly.

Why it is worth a survey now in Tapnage
Some breaches are too small to see. Electronic testing can find breaches you can’t see by eye, on suitable membranes. In a small place like Tapnage, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You’ll know the exact price before you book.

Tapnage questions
Is the coastal weather around Tapnage hard on roofs?
Frequently, yes. Within about 4 miles of the sea, as Tapnage is, metal fixings wear faster and gales find any loose ridge or slate.
Will you come out to Tapnage?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Does the report include photos?
Yes. Photographs are part of every report, so you can see each point for yourself.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years, across London and South East England.
Can you survey a shared roof?
Yes, if whoever owns or manages the building agrees access. On a shared roof we can only inspect the parts we are allowed to reach.
What do I do with the report?
You receive the written report by email, with photos and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Do I need to be at home?
Not necessarily. If we only need the outside, we can agree that ahead of time, but anything inside needs someone there to give access.
What we do, step by step
Photographs are taken throughout the visit, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available, including by drone where it’s applicable and the weather allows. Most surveys take more time on a big roof than a small one, with the construction of the roof playing a part too. Somewhere like Tapnage needs a little journey planning: let us know about lanes, gates and parking. On the day, we inspect whatever is safely visible, inside and out.
- 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.
Getting ready for the survey
- Let us know about parking near the property
- Point out any leaks or damp patches
- Keep pets inside or away from the areas we’re looking at
How to book
If you are buying, it is useful to book soon after your offer is accepted, so there is time to use the report before exchange. Otherwise, simply ring 07833 053749 or send us an email whenever suits you.
Advice
What we look for on each type of roof
Green and ballasted roofs
Some layers may need lifting for testing. We discuss this before quoting.
Inverted and paved roofs
We will tell you if your inverted or paved roof isn’t suitable.
Prices for electronic leak detection in Tapnage
Prices vary from roof to roof, and it comes down to:
- Roof area
- The number of roofs, including extensions and garages
- Features like valleys, chimneys, dormers and parapets
- House, block, shop or office
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You’ll know the figure before booking.
What to let us know when you get in touch
These details help when you contact us:
- Any deadline, like an exchange date
- Pictures from the garden or a window, if you have them
- The reason for the survey, such as buying, a leak or storm damage
- Where water is showing inside, if it is
Photos help, if you have them. Pictures from the ground or a window are fine, and please do not climb up for a closer look. To send them or to book, phone 07833 053749 or use the contact form.
Before and after the survey
A few practical points come up again and again on our surveys. They apply to most roofs:
- Note where leaks show inside and when
- Keep foot traffic on flat roofs to a minimum
- Share any drawings of the roof
- Act on new leaks promptly
Once repairs are made, the roof can be tested again if you want to check them, where the roof still suits the method.
Limit foot traffic on flat roofs. Many breaches come from foot traffic.
Flat and commercial roofs around Tapnage
Tapnage lies within about 4 miles of the sea, and places near the sea get more salt in the air and more wind than inland. Wind can catch loose edges and trims on a flat roof, and salt air is hard on metal trims, flashings and fixings. A number of Hampshire villages keep thatched roofs on their older buildings. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For site and facilities teams at buildings such as The Henry Cort Community College, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. Shop and office owners around Fareham Shopping Centre may find that the flat roofs over shops and commercial units are worth checking before a leak, not after.
Tapnage is about 3 miles north of Fareham, in Hampshire. Surveys in Tapnage work the same way as everywhere we cover: a careful look at whatever is safely visible, photographs and a clear written report.

When to book a survey in Tapnage
Roofs covered with paving, ballast or planting hide the membrane. ELD can work on some covered roofs, depending on the build-up.
Here are some of the things we see frequently:
- Leaking laps in the waterproofing
- Leaks that return after repairs
- Waterproofing to test before it’s covered
- Leaks through a covered membrane
For landlords with property near Swanwick station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
