About our chimney survey in Merstham
A chimney survey is about the outside of the stack and the roof around it. It isn’t a flue inspection, a sweep or a gas safety check. For the flue itself, you’ll need a sweep or, for gas appliances, a Gas Safe registered engineer. If something we see points to the flue, we’ll say so. We survey lead flashings, shared and party-wall stacks and flaunching, and the problems we are asked to look at most are cracked or missing flaunching and flashings pulling away from the stack.
Older buildings in small places like Merstham may be listed or in a conservation area. That can affect what materials can be used when work is done, so check with the council before planning anything. A roof report helps you plan work with that in mind. Older materials such as clay tiles, slate and stone are often matched when work is done.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

Landlords, agents and block managers in Merstham
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work with less disruption.
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait, which helps with budgets and planning.
Before and after the survey
You don’t need to be a roofer to help. Here’s what helps most:
- Note any damp on chimney breasts and when it appears
- Remove aerials or dishes from the stack if they’re no longer needed
- Book a sweep for flues that are in use
- Ask for ventilated caps on redundant stacks
Questions about the findings are always welcome. Standard Surveys come with a follow-up consultation, and Premium Surveys with an in-person one.
Make sure fixings on the stack are sound, and moved if they’re working it loose. Removing unused fixings takes strain off the brickwork.
Roof by roof
Lead flashings
Some older stacks have mortar fillets instead of lead. They crack with age, and we check them too.
Brick stacks
Spalled bricks, where the face has flaked off, are a sign of water and frost. Any spalling is noted with photos.
Signs you need a chimney survey in Merstham
Years of fires can affect the mortar inside a stack. Flue gases and damp can break down the mortar, sometimes more on one side than the other, which is one reason stacks start to lean.
Here are some of the things we see often:
- Disused chimneys trapping moisture
- A stack that appears to lean
- Flaunching that has broken away
- Staining on walls around the chimney
If you look after a shop, office or commercial unit, for example near The Belfry, a written record of the roof’s condition helps you plan maintenance rather than react to leaks.
Choosing a roof surveyor
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Will the report include photos?
- Will they check the loft as well as the outside?
- How long the report takes to arrive
The survey, step by step
After the inspection, everything we found is written up as a report with photos, sent to you by email. As for time on site, most surveys take between one and two hours at a house, as part of a look at the roof around the stack. Somewhere like Merstham needs a little journey planning: let us know about lanes, gates and parking. The roof is looked at from the ground, from windows, from the loft where there’s safe access and from the roof where it’s safe.
- First we talk through the stacks, their history and any problems.
- We check every stack from wherever it can be seen safely.
- Pots, cowls, flaunching, pointing and flashings are checked and photographed.
- We look for damp on chimney breasts and in the roof space.
- The report, with photographs and recommendations, is emailed to you.
Before the survey
- If it isn’t your property yet, arrange access through the agent
- Keep pets in another room
- Make sure we can get to the back of the property

Related advice
What happens if roof problems are left?
Most people never get a careful look at their chimney stacks. Defects tend to go unseen until there’s a stain. Surveying the stack now can catch problems first. Where a roof is exposed, as many are in small places like Merstham, driving rain gets into any weakness, and damp in older walls is slow to dry out.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You’ll know the figure before booking.

What a chimney survey looks like in Merstham
Handmade clay tiles and tile-hung walls are typical of Surrey’s older houses. Horsham stone slab roofs survive on some old buildings in Surrey. Whatever the covering, it is often the fixings, flashings, valleys and gutters that give out first. Listing and conservation areas can both shape what roof work is allowed on an older home. Your council and Historic England’s list will tell you where you stand.
Trees in and around Nutfield Marshes shed leaves that can end up in nearby gutters, and an overflowing gutter soon means a wet wall. If you let a flat or house near Merstham station, knowing the condition of the roof, chimneys and gutters helps you plan work rather than react to complaints.

Common questions in Merstham
Do you survey roofs for landlords with property near Merstham station?
Yes, that’s a common request. Let us know whether a tenant or an agent will let us in, and the report can go straight to you or your agent.
Is my home in Merstham listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do I need to be at home?
Not always. If we only need the outside, we can agree that ahead of time, but the loft and any rooms with damp need someone to let us in.
What’s the best way to book?
The quickest way is to call 07833 053749 or email us. Give us the address and a few details about the roof. We survey on weekdays and at weekends.
Why is my chimney breast damp?
There are a few common causes: water getting in at the top, through the brickwork or at the flashings, or moisture trapped in a stack with no ventilation. We check each one and note the most likely cause.
Is it a structural engineer’s report?
No. We are roof surveyors, not structural engineers, and it doesn’t include calculations. If we see signs that need an engineer’s opinion, we will recommend one.
Will you walk on the roof?
Only when it is safe. Safety comes first, and fragile or steep roofs can’t always be walked on. We use safe viewpoints, the loft space and a drone where applicable.
