Independent roof leak investigations in Cadnam. More than 5,000 surveys completed across London and South East England.

- Drips from nail tips in a cold loft
Common roof problems in Cadnam
Flashings are one of the commonest sources of roof leaks. Lead or mortar closes the gap wherever a roof meets a wall, chimney or dormer. When lead lifts or splits, or a mortar fillet cracks, rain runs straight in, frequently well away from where it shows.
A survey can pick up problems like:
- Ceiling stains that grow after rain
- Water that shows only in certain storms
- Damp on a chimney breast
- Condensation that looks like a leak
If your home is one of the older ones in the streets near Church of St Mary, water on an older roof tends to find its way in at the lead, the valleys or the chimney.
Questions to ask before booking
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- Will the report include photos?
- Whether you can ask questions once you have the report
- Whether the price includes VAT
How a roof leak investigation works in Cadnam
Water is good at hiding where it gets in. Water often travels along timbers or underlay before it finds a way down, so a ceiling stain is rarely directly below the cause. Our leak investigation traces it back, one likely route at a time. Patching the spot above the stain often misses the real cause. Finding the route first lets the repair go where it is needed. We survey chimney stacks, slate and tile slopes and the roof space, and common reasons people get in touch are stains around a skylight and water marks that spread in wet weather.
In a village or hamlet like Cadnam, older cottages and farmhouses often have roofs that have been patched over many years. That makes it hard to tell new damage from old wear, and the difference matters, particularly to an insurer. The report says what was seen and what it points to. Older walls and timbers hold water for a long time, so it’s worth finding the cause soon.
After the visit, you get a report with photos, sent by email. It sets out the condition of the leaking roof, any defects and our written recommendations.

DIY checks: what’s safe
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it.
Your own check is a good start, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight.
Leaks and storm damage in Cadnam
Cadnam lies within about 5 miles of the sea, where sea air brings more salt and stronger wind than inland. In a coastal gale, rain is driven sideways into laps, verges and flashings. Thatch survives on some older buildings in Hampshire’s villages. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Different coverings let water in at different points, which shapes where the search starts.
With Landford Manor about 4.6 miles north-west, the area around Cadnam has a long history. On older roofs nearby, leaks frequently trace back to lead flashings, valleys and gutters. Anyone responsible for a site like Bartley Church of England Junior School will know that tracing a leak on a big roof starts with where the water appears and works back.
Cadnam is about 3 miles west of Totton, in Hampshire. In Cadnam, as across Hampshire, every roof gets the same careful survey. Cadnam is one of the towns and villages in Hampshire where we work for roof leak investigations. Southampton is in our area too.

Tips from our surveys
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Check whether pipes or tanks run near the stain
- Don’t climb onto the roof to look
- Have an electrician check any wet fittings
- Photograph the stain each time it appears
Once the work is done, hold on to the report. If water appears again, it shows what was found before, which makes the next step quicker.
After a downpour, look in the roof space with a torch, keeping to boarded areas. Look for drips, damp patches and stains on timbers. Photograph anything new.
Common questions in Cadnam
Will you come out to Cadnam?
Yes. Cadnam is within the area we cover, which takes in towns, villages and rural addresses. We survey roofs across London and the South East. Just mention lanes, gates or anything else about the route as you book.
Does being near the coast affect roofs in Cadnam?
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.
What happens next?
You’ll receive the report by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
How long does a roof leak investigation take?
Allow an hour or two, more where the leak is intermittent or the roof is large. We will confirm what to expect when we arrange the visit.
Do you need to get into the loft?
Yes, where the survey calls for it and there’s safe access. Inside, we look for damp, staining, gaps and sagging.
Is it a leak or condensation?
The two can look alike. Drips from nail tips, damp underlay over a wide area and poor loft ventilation point towards condensation. We look at the pattern, take moisture readings and tell you which is more likely.
Does the report include photos?
Yes, every report has them. Each finding is shown in a picture where possible, so you can see what we mean.
How we price roof leak investigations

- If the survey needs thermal imaging or a drone
- Extra roofs, like extensions, dormers or garages
- Features like valleys, chimneys, dormers and parapets

Booking your survey
If you can, have these to hand when you contact us:
- Any photos you have, taken from ground level or a window
- What’s prompted the survey
- Whether there is a loft hatch, a shared roof or tricky access
- Your postcode, so we can check access and travel
We survey roofs seven days a week. To find a date that works for you, phone 07833 053749 or email us with the address and the days you’d prefer.
What happens if roof problems are left?
Damp in a ceiling or loft can lead to mould. Once mould takes hold, it’s harder to clear. Finding the leak comes first. Older and listed buildings around Cadnam may need consent and matching materials for repairs, so a defect found early gives time to plan the work properly.
A Basic Survey starts from £150, including VAT. The Standard Survey starts from £250 and the Premium Survey from £400. We confirm the price for your survey before booking.

What we do, step by step
Safety comes first on every visit. Everything that can be seen safely is inspected, and anything we cannot see is noted in the report. Most visits take about 1–2 hours for a house, and about three to four hours for a commercial roof. Somewhere like Cadnam needs a little journey planning: let us know about narrow lanes, gates, long drives and where we can park. The roof is looked at from the ground, from windows, from the loft where there is safe access and from the roof where it’s safe.
- You get in touch with details of the leak and any photos.
- The visit starts indoors, at the stain and in the loft.
- Outside, we check every likely route in.
- Moisture readings and thermal imaging are used where they help.
- You receive a written report with photos showing the likely source and what needs attention.
Before we arrive
- Have any paperwork from past roof work to hand
- Mention any parking restrictions on your street
- Agree roof access with the managing agent if it’s shared
