About our electronic leak detection in Copnor
Roofs covered with paving, ballast or planting need more thought. What sits on the membrane can affect which method will work, and some may need lifting. We talk this through before we quote. Drawings or details of the roof’s layers are useful because they show what’s under the surface. If testing isn’t possible, we’ll say so. We survey flat roof membranes, green roofs and roof terraces and balconies, and common reasons people get in touch are leaking laps in the waterproofing and leaks at pipes, outlets or fixings.
In smaller places like Copnor, flat roofs are mostly on extensions, garages, porches and dormers. They’re small, but a leak over a kitchen extension can do a lot of harm. What it’s covered in, and how well it was laid, decides what it needs. From an upstairs window, look for standing water, splits and edges coming away.
We write the report in plain English, so it makes sense without any roofing background. Each point is backed by a photograph where possible.

How we price electronic leak detection
Several things affect the price of a survey:
- How many separate roofs there are, such as extensions, dormers and garages
- The use of thermal imaging or a drone
- The shape of the roof and its details
- How big the roof is
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Booking your survey
The more you tell us, the easier it is to price the survey. When you contact us, tell us:
- Any marks or damp showing indoors
- How the loft is reached, if there is one
- The property’s address and postcode
- What’s prompted the survey
Our phone lines are open seven days a week. For a price or to book, call 07833 053749 or send us an email.
Electronic leak detection in Copnor: local notes
The coast is about 1 mile or less from Copnor, 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 buildings in Hampshire’s villages. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If you run a business near The Bridge Shopping Centre, the flat roofs over shops and commercial units are worth checking before a leak, not after. Take an older house close to Church of St Alban: any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
Copnor is about 1 mile east of Portsmouth, in Portsmouth. If you’re in Copnor, booking works exactly as it does anywhere else: a call or an email, a price, then a date. Copnor is one of the towns and villages in Portsmouth where we work.

What happens on the day
Safety comes first on every visit. Everything that can be seen safely is inspected, and anything we can’t see is noted in the report. The survey usually takes a time that depends on the size of the roof and how it’s built, which we’ll explain when we quote. A visit to a smaller place like Copnor is no different on the day: outside, inside and from any safe vantage point, in that order. It helps to show us anything you’ve already noticed.
- First, you let us know about the roof build-up and where water is showing.
- We confirm whether the roof is suitable for electronic testing.
- The method depends on the membrane and what sits above and below it.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
Preparing for the visit
- Let us know about parking near the property
- Have any questions written down, so nothing gets missed
- Leave side gates unlocked
Booking a survey
Getting a price is simple: just phone 07833 053749 or email us and give us some details about the property and we’ll explain which survey suits. The price is agreed up front.

When to book a survey in Copnor
Work on the roof can damage a membrane. Fixings, equipment and foot traffic can leave small holes.
People normally book a survey after spotting something like this:
- Breaches hidden under paving or planting
- Damp inside with no sign on the roof
- Holes around roof penetrations
- Leaks that return after repairs
Anyone responsible for a site like Westover Primary School will know that schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.
Before you book anyone
- Which limits apply to the survey
- Their insurance cover
- How long the report takes to arrive
- How much experience they have with roofs like yours
What this survey cannot tell you
It is useful to know what a survey will not do before booking:
- Moisture spread under the membrane
- Leaks from walls, copings or rooflights
- Repairing the breaches (that’s for your roofer)
If in doubt, phone 07833 053749 or use the contact form and we will recommend the right survey before booking. What our survey covers.
Roofs we survey in Copnor
- Flat roof membranes
- Single-ply roofs
- Green roofs
- Liquid-applied waterproofing
- Commercial flat roofs
- Roof terraces and balconies
What you can safely check yourself
A DIY look is useful, but it is not a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight.
A lot can be seen from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please do not climb up for a closer look.
Copnor: your questions answered
Is my home in Copnor listed or in a conservation area?
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.
Will you come out to Copnor?
Yes, smaller places are covered as well as towns. We survey roofs across London and South East England. Just mention lanes, gates or anything else about the route as you book.
Do you need to get into the loft?
Typically, if there is one and it can be reached safely. From inside, the underside of the roof frequently shows damp, staining or daylight that cannot be seen from outside.
What does the report include?
It sets out what we found, why it matters and what we recommend, with photographs throughout. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
Can you give me structural calculations?
No. Our survey is not a structural engineer’s report, and it doesn’t include calculations. If we see signs that need an engineer’s opinion, we’ll recommend one.
Does the report include photographs?
Yes, plenty. Pictures sit next to the findings they show, which makes the report easy to follow.
Is it the same as a RICS Level 2 or Level 3 survey?
No. This is a survey of the roof only, so it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
Tips that help
There’s plenty you can do without going near the roof. Here’s what helps most:
- Share any drawings of the roof
- Consider ELD before paving or planting goes on
- Make sure trades protect the waterproofing
- Avoid repeated repairs without finding the cause
If anything in the report is not clear, ask us. We can talk you through the findings.
Don’t leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
