Sepham Heath homes and their roofs
With Lullingstone Castle about 3.1 miles north-east, Sepham Heath sits in an area with a long building history. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area. Across Kent, older roofs are frequently handmade clay or peg tiles, and tile-hanging on upper walls is a familiar sight. Oast houses and timber-framed Wealden hall houses are part of the county’s older buildings too. On roofs like these, good slates or tiles can outlast the nails, battens, lead and mortar around them.
For landlords with property near Knockholt station, a dated record of the roof is useful when planning maintenance across a let. For an older house near a landmark such as Otford Lane Mission Church, old fixings, lead flashings and tall chimneys are typical of older roofs.
Sepham Heath is about 3 miles north-west of Sevenoaks, in Kent. We survey roofs in Sepham Heath and the rest of Kent, as part of our work across London and South East England. Across Kent, we cover Sepham Heath and the places around it. There is also a page for London.

Chimney survey in Sepham Heath: what you get
Chimney stacks take more weather than almost any other part of a house. In time, flaunching cracks, mortar washes out and flashings come loose. Water then gets into the stack and can show as damp on a chimney breast or a stain in the loft. We record what we find with photos and recommendations. We survey flaunching, brick chimney stacks and chimney pots and cowls, and the problems we’re asked to look at most are unused flues sealed without airflow and cracked or missing flaunching.
Somewhere as small as Sepham Heath, homes are often older cottages and farmhouses, with outbuildings and some newer houses. Older roofs may be clay tile, slate, stone or thatch, frequently with chimneys that have stood a long time. Each needs checking in its own way, and thatch is a specialist material we report on as far as it can be seen. Chimneys and lead flashings on old roofs frequently need the most attention.
It isn’t only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

Tips that help
A few practical points come up again and again on our surveys. They apply to most roofs:
- Keep the report to compare against at the next survey
- Check with the council before altering a stack in a conservation area or on a listed building
- Photograph damp patches with the date
- Check that disused chimneys can still breathe
If anything in the report is not clear, just ask us. Standard Surveys come with a follow-up consultation, and Premium Surveys with an in-person one.
Check redundant flues are capped with ventilation. Ventilation helps keep the stack dry.
Honest limits
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- The inside of the flue, which needs a sweep or flue specialist
- Areas we can’t view from safe positions
- Conditions inside walls
If in doubt, ring 07833 053749 or send us an email and we will suggest the right survey before booking. What a survey covers and doesn’t.
What this survey covers

- Chimney breasts
- Chimney pots and cowls
- Brick chimney stacks
- Flaunching
- Shared and party-wall stacks
How the survey works
Every roof is different; as a rough guide, the survey takes about 1–2 hours at a house, as part of a look at the roof around the stack. If you have questions on the day, just ask. Rural addresses near Sepham Heath can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- We start by noting which stacks are in use, shared or causing concern.
- We check the roof around each stack, including the flashings.
- The top of each stack is checked for cracked flaunching and loose pots.
- Any lean, spalling or worn pointing is recorded.
- The report explains the condition and which work is most urgent.
Preparing for the visit
- If you are buying, check with the agent that we can get in
- Tell us about any leaks, stains or damp patches you know of
- Jot down any questions you want answered
Arrange a survey
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. For any other survey, just call 07833 053749 or send us an email when you’re ready.

Your questions about chimney surveys in Sepham Heath
Is my home in Sepham Heath listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
I let a flat near Knockholt station. Can you check the roof?
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.
Does this replace a RICS home survey?
No. We’re experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you will need a RICS survey as well.
What do I do with the report?
You’ll receive the report by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
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.
What if it rains on the day?
It can, depending on the survey. Drones cannot fly safely in strong wind or a downpour, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. We will rearrange with you if the weather is not right.
Is a leaning chimney dangerous?
It’s worth having a leaning stack checked. Our survey notes how it looks and the condition of the bricks and joints, and recommend a structural engineer where it may be a structural concern.
How the survey changes by roof type
Chimney pots and cowls
For unused flues, we check whether caps or cowls allow ventilation. Capping without ventilation can trap moisture.
Chimney breasts and the loft
If a chimney breast has been removed below, we note what we can see of the support above. A structural engineer should confirm whether it’s adequate.
Common roof problems in Sepham Heath
Removing a chimney breast inside can leave questions about how the stack is supported. We record what we can see in the loft and outside, and the report recommends a structural engineer if support is a concern.
Here are some of the things we see frequently:
- Cracked or missing flaunching
- Spalled or crumbling bricks
- Staining on walls around the chimney
- Loose, cracked or missing pots
If you live near a park like Polhill Bank, or anywhere with mature trees, autumn leaves can block gutters and valleys, and an overflowing gutter soon means a wet wall.
What to check before booking
- What they won’t be able to tell you
- What exactly goes into their report
- Which viewpoints they use to see the roof
- Whether the price includes VAT
Why act early in Sepham Heath
For a buyer, the best time to learn about a chimney is before exchange. After that, any work is yours to arrange and pay for. Our report gives you facts to raise with the seller or agent. For older village homes like those around Sepham Heath, the right replacement materials aren’t always easy to find quickly. That’s one more reason to find defects before they become urgent.
Prices start from £150, inc. VAT, for a Basic Survey. Standard is from £250 and Premium from £400, both including VAT. We confirm the exact price before booking.
