Chimney survey in Cosham: what you get
Damp on a chimney breast can have several causes. It might come in at the top, through worn pointing or porous bricks, or where the flashings meet the roof. Moisture trapped inside a stack with no ventilation can also cause damp. Our survey checks each of these and records the likely cause. You then know where to start. We survey shared and party-wall stacks, chimney pots and cowls and lead flashings, and the problems we are asked to look at most are flaunching that has broken away and damp patches on chimney breasts.
Trees around homes in smaller places like Cosham drop leaves, twigs and moss onto roofs and into gutters. Once gutters and outlets block, water spills over and soaks the walls. It is the kind of slow problem a roof report picks up early. Moss on the roof and weeds in the gutter are both easy to spot from ground level.
Every survey ends with a written report, with photos, sent by email. It sets out the condition of the chimney stack, any defects and our written recommendations.

Rented homes, blocks and businesses
Buyers’ agents can book surveys on behalf of their clients. Reports are emailed, so they’re easy to pass on.
Managing agents and residents’ management companies use roof surveys to plan maintenance. The report sets out what needs attention now and what can wait.
What this survey can’t tell you
It’s a careful look at the chimney stack, not the whole story. Its limits include:
- Whether a stack needs rebuilding on structural grounds
- Hidden sides of a shared stack
- Whether a gas appliance or its flue is safe
If in doubt, call 07833 053749 or email us and we will recommend the right survey. The full list of what we check.
What this survey covers
- Shared and party-wall stacks
- Lead flashings
- Chimney pots and cowls
- Brick chimney stacks
- Flaunching
- Chimney breasts
Why it’s worth a survey now in Cosham
A leaning stack should be looked at sooner rather than later. We record its condition and recommend a structural engineer where needed, so you can decide what to do next. In an older home around Cosham, water from a roof defect can get into timber and plaster, which is far harder to put right than the roof fault itself.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You will know the figure before booking.
Why book with us
- 5,000+ surveys completed
- An independent look at the roof
- More than 20 years surveying roofs
- Drone flown under a CAA Flyer ID and Operator ID

Cosham homes and their roofs
Cosham lies within about 1 mile of the sea, and places near the sea get more salt in the air and more wind than inland. Near the sea, metal fixings wear faster and loose pieces on a roof are more likely to lift, and driving rain gets into whatever gap is left. About 4.4 miles east lies Warblington Castle, a reminder of how long the area around Cosham has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material.
If you live near a park like Alexandra Park, or anywhere with mature trees, autumn leaves can block gutters and valleys, and blocked gutters overflow and soak walls. Shop and office owners around Tricorn Centre may find that a written record of the roof’s condition helps you plan maintenance rather than react to leaks. Landlords with a home close to Cosham station may find that knowing the condition of the roof, chimneys and gutters helps you plan work rather than react to complaints.

The survey, step by step
The visit has one job: to look at the chimney stack as closely as is safe and record what we find. Everything we note and photograph goes into the written report. The visit usually takes an hour or two for most homes, a little longer where there are several stacks. In a smaller place like Cosham, parking is seldom the issue; lanes, gates and long drives are worth mentioning. On bungalows and lower roofs, much can be seen from ground level, with the loft showing the underside, while taller roofs may need other vantage points or the drone where it applies.
- First we talk through the stacks, their history and any problems.
- Each stack is inspected from safe positions outside.
- We photograph and record the pots, flaunching, pointing and flashings.
- Inside, the chimney breasts and the loft are checked for damp where there’s access.
- You get a written report with photos and recommendations by email.
Getting ready for the survey
- Make a note of anything you’d like us to look at

What else we do in Cosham
How the survey changes by roof type
Lead flashings
Some older stacks have mortar fillets instead of lead. They crack with age, and we check them too.
Flaunching
Cracked flaunching is one of the most common chimney defects we record. It is normally a modest repair when it is caught early.
What affects the price in Cosham
Several things affect the price of a survey:
- Extensions, dormers and garages with roofs of their own
- Height and safe access
- How big the roof is
- The type of building, from a house to a block or an office
Prices quoted always include VAT, and the written report is part of the package. Prices start from £150, including VAT. Size, height and access decide where your roof falls.
Booking your survey
Here’s what helps us most when you get in touch:
- Any deadline, like an exchange date
- The type of building and roof, such as pitched or flat
- How the loft is reached, if there is one
- Where water is showing inside, if it is

Questions from Cosham
Does a conservation area affect roof work in Cosham?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
Can a landlord with a rental near Cosham station book a roof survey?
Of course. Let us know whether a tenant or an agent will let us in, and the report can go straight to you or your agent.
What will the report tell me?
You get our findings in writing, part by part, with photos. Points are put in order of urgency where relevant.
I live in a flat. Can you survey the roof?
Yes. A shared roof needs access agreed first. Let us know about it when you book and we will plan the survey around it.
What do you check on a chimney?
The whole stack, as far as it can be seen safely: pots, cowls, flaunching, pointing, bricks and flashings. Leaning, unused stacks and damp on chimney breasts are recorded too.
Should a redundant chimney be removed?
There is no single answer. The survey shows its condition and how it’s been capped. In a conservation area or on a listed building, changes may need consent.
Does the report include photographs?
Yes. The report includes photos of what we found, so you can see each point for yourself.
