Electronic leak detection in Colwell
Some flat roofs can’t be tested electronically. Some membranes conduct electricity themselves, and some build-ups lack the layer the test needs below the membrane. If your roof is not suitable, we’ll tell you before any testing. 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 cannot give results. If you are worried about damage from equipment installers and new roofs to check before paving or planting, a survey will tell you what’s going on, on single-ply roofs, liquid-applied waterproofing and flat roof membranes alike.
In a small place like Colwell, a flat roof can stand in the open, so edges, upstands and laps take a beating. Felt roofs, which frequently last around 15–20 years, typically show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
We keep jargon out of it: where something needs attention, it says so plainly.

Do you need electronic leak detection in Colwell?
Water travels under flat roof membranes. The leak may show some distance from where water gets in which makes it hard to find by looking.
Problems we come across often include:
- Holes left by work on the roof
- Leaks that return after repairs
- Damp inside with no sign on the roof
- Holes around roof penetrations
Take a building like All Saints Church of England Primary School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Colwell: your questions answered
How do I find out if my home in Colwell is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Do roofs near the sea, like those around Colwell, take more of a battering?
It can do. Colwell is within about 1 mile of the sea, and coastal roofs tend to see faster wear on metal parts and more wind lifting loose pieces.
Can you survey at the weekend?
Visits run seven days a week in the daytime, which suits people who work during the week. Let us know your preferred days when booking.
Will you photograph what you find?
Yes, plenty. Pictures sit next to the findings they show, so you can see what we mean.
How do you choose the testing method?
The method is chosen to suit the roof. Low-voltage testing typically needs a wet surface and high-voltage methods need the membrane dry and exposed.
Do you test for asbestos?
No. Asbestos surveys and testing aren’t part of what we do. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings and suggest a specialist asbestos surveyor checks them before any work.
What is electronic leak detection?
A sound membrane blocks the test current, but a hole lets it through. That is how we locate breaches you cannot see.
What affects the cost of electronic leak detection
We confirm the price for your roof before you book. This is what makes a difference:
- How many separate roofs there are, such as extensions, dormers and garages
- Any need for thermal images or a drone flight
- How complicated the roof is, with its valleys, chimneys and parapets
- The size of the roof
To find out what your survey will cost, ring 07833 053749 or use the contact form with the address and a few details. The price is agreed before a date is set.
Booking your survey
If you can, have these to hand when you get in touch:
- The type of building and roof, such as pitched or flat
- Where water is showing inside, if it is
- Your postcode, so we can check access and travel
- The reason for the survey, such as buying, a leak or storm damage
Photos help, if you have them. Pictures from ground level or a window are fine. To get started, ring 07833 053749 or send us an email.
What we look for on each type of roof
Liquid-applied waterproofing
Testing a liquid-applied roof depends on what’s beneath the coating.
Single-ply membranes
Punctures from foot traffic and equipment are common on single-ply roofs. Testing helps find them.
The survey, step by step
Every visit follows the same pattern: we listen to what’s been worrying you, look at the roof from every safe viewpoint, take photographs as we go and record our findings for the written report. It typically takes as long as needed for the roof’s area and construction, and we’ll give you a guide when quoting. Cottages and farmhouses around Colwell frequently have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints, and anything we cannot see is noted.
- We start by finding out what the roof is made of and where it leaks.
- We check that the membrane and build-up suit electronic leak detection.
- The testing method is chosen to suit the membrane and build-up.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photos in a report for your roofer.
Preparing for the visit
- Point out any leaks or damp patches
- Buyers: confirm access with the estate agent or seller
- Gather any invoices or paperwork from past roof work
Getting a price
Booking is simple: just call 07833 053749 or email us and give us a few details about the property and we will explain which survey suits. We confirm the price before anything is booked.
Advice
What electronic leak detection doesn’t cover
In fairness, a roof survey has limits:
- Water entering through details rather than the membrane
- Repairing the breaches (that’s for your roofer)
- Some conductive membranes
If in doubt, phone 07833 053749 or use the contact form and we will recommend the right survey. What a survey covers and does not.

Local flat roofs in Colwell
Colwell lies within about 1 mile of the sea, and being near the sea means more wind and salt than a roof inland would face. On a flat roof near the sea, edge trims and upstands take the brunt of the wind, and metal parts corrode faster. Thatch survives on some older Isle of Wight buildings, and sea air and wind reach every part of the island. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If you live in an older home near Christ Church, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. Landlords with a home close to Lymington Pier station may find that the flat roof over a let home is worth a look before it becomes a tenant complaint.
