Useful tips for New Denham property owners
A few practical points come up again and again on our surveys. They apply to most roofs:
- Never climb onto the roof to look at a chimney
- Find out whether changes to a stack need permission
- Note any damp on chimney breasts and when it appears
- Book a sweep for flues that are in use
If the report recommends a structural engineer, a sweep or a Gas Safe registered engineer, it will say why. That helps you brief them.
Keep an eye on chimney breasts for new damp patches. The sooner damp is spotted, the easier the cause is to find.
How a chimney survey works in New Denham
Each stack is looked at from the safest viewpoints available: from the ground, from windows and vantage points, and from the loft where there’s access. With our Premium Survey, a drone inspection is included where it applies. Where part of a stack can’t be seen, the report says so. Every defect we find is photographed and described in plain words. We survey chimney breasts, shared and party-wall stacks and lead flashings, and the problems we’re asked to look at most are mortar washing out of the joints and a chimney out of line.
In a small place like New Denham, many roofs stand in the open, so ridges, chimney stacks, flashings and gutters work hard. Older walls take a long time to dry once water gets in. A roof report shows what needs attention first. Lead flashings and old chimney stacks are often where weather gets in first.
After the visit, you get a written report with photos, emailed to you. It sets out the condition of the chimney stack, any defects and our written recommendations.

How the survey changes by roof type
Brick stacks
Many older stacks were built with lime mortar. We note where repairs should match the original mortar.
Rendered stacks
Cracked render can let water in and trap it behind. We record any cracking and where it is.
Signs you need a chimney survey in New Denham
Aerials and dishes are frequently fixed to stacks. Their weight and the wind on them can loosen bricks and pointing. Any fixings on the stack are checked and recorded.
Here are some of the things we see often:
- Bricks with flaking faces
- Mortar washing out of the joints
- Unused flues sealed without airflow
- Damaged chimney pots and cowls
For landlords with property near Denham station, knowing the condition of the roof, chimneys and gutters helps you plan work rather than react to complaints.
What to check before booking
- Whether they hold professional indemnity and public liability insurance
- Will they check the loft as well as the outside?
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Their track record with similar roofs
What happens on the day
We check the roof from outside and, where it is relevant and there is safe access, from inside the loft space too. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. All in, the survey usually takes roughly 1–2 hours at a house, as part of a look at the roof around the stack. In a hamlet or village like New Denham, a postcode doesn’t always lead to the right gate, so a few directions are welcome. The visit itself is the same as anywhere else.
- You tell us whether any stacks are shared, unused or leaning.
- The flashings and the roof around each chimney are inspected.
- The top of each stack is checked for cracked flaunching and loose pots.
- Any lean, spalling or worn pointing is recorded.
- You receive a written report setting out what needs attention first.
How to prepare
- Gather any invoices or paperwork from past roof work
- If it isn’t your property yet, arrange access through the agent
- Tell us where we can park nearby

Chimney surveys around New Denham
With Ickenham Hall about 2.1 miles east, New Denham sits in an area with a long building history. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first. Some villages in Buckinghamshire still have thatched roofs. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Knowing the covering helps explain which parts of a roof are likely to need work first.
If yours is one of the older homes in the streets near St Francis, its chimney, valleys and lead work are likely to be the parts that need attention first. Take a building like Hermitage Primary School: large buildings have long gutter runs and big roofs that need checking like any other.

Your questions about chimney surveys in New Denham
I let a flat near Denham station. Can you check the roof?
Yes, that is 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 New Denham listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Do you inspect shared chimneys?
Yes. Shared stacks are common on terraced and semi-detached houses. We record the stack as far as we can see it and flag anything on the neighbour’s side.
How many surveys have you done?
We have completed more than 5,000 surveys, across 20+ years of surveying roofs, with 98% customer satisfaction.
What if it rains on the day?
It depends on the weather and the survey. In strong wind or heavy rain, a drone can’t fly and access may not be safe, so we’d move the date with you.
Can you survey a shared roof?
Yes, as long as access is agreed. Roofs over flats are frequently shared, so we need permission from whoever owns or manages the building. We can only inspect what we’re given access to.
Should a redundant chimney be removed?
An unused stack still needs to stay weathertight and ventilated. Capping without airflow can lead to damp. Our survey records its condition and how it’s capped, so you can decide with a builder what to do.
