Kemsing roofs and the weather
Older houses across Kent often have handmade clay or peg tiles, and many have tile-hung walls. Oast houses and timber-framed Wealden hall houses are part of the county’s older buildings too. Different coverings let water in at different points, which shapes where the search starts. With Knole House about 2.8 miles south, Kemsing sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.
Homes near green spaces like Kemsing Down can get more leaves in their gutters in autumn. For an older house near a landmark such as Church of St Mary, old mortar, worn lead and slipped slates are the usual suspects when water gets in. Landlords with a home close to Otford station may find that a tenant living with a leak needs the cause found, not just the stain painted over.

About our roof leak investigation in Kemsing
Water is good at hiding where it gets in. Water often travels along timbers or underlay before it finds a way down, so the stain on your ceiling is seldom right under the hole. Our leak investigation traces it back. Patching the spot above the stain often misses the real cause. Tracing the route first means any work can be aimed at the right place. If you’re worried about damp patches next to the stack and leaks below a flat extension roof, we can find out what’s behind it, whatever the roof.
In a smaller place like Kemsing, some roofs face open ground, where driving rain gets into any gap at a ridge, verge or flashing. A leak that only appears in certain weather often points to an exposed detail. Let us know when it happens when you get in touch. Gutters and downpipes on the exposed side are worth a look as well.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

What we do, step by step
We do not take risks to get a closer look. We inspect everything that’s safely in view, and anything we cannot see is noted in the report. The survey normally takes roughly 1–2 hours at most homes, with bigger or more complicated roofs taking longer. A visit to a smaller place like Kemsing is no different on the day: outside, inside and from any safe vantage point, in that order. Point out any stains, cracks or loose pieces you’ve spotted.
- We start with what you’ve seen: where the stain is and when it gets worse.
- Inside, we check the damp area and the loft space above it.
- Outside, we check every likely route in.
- We use moisture detection, and thermal imaging where it’s useful.
- You receive a written report with photos showing the likely source and what needs attention.
Getting ready for the survey
- If the roof is shared, arrange access with whoever manages the building
- Note where any stains or damp appear
- Have any questions written down, so nothing gets missed

Kemsing: your questions answered
Is my home in Kemsing listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it is worth checking before planning any.
Do you carry out roof surveys in Kemsing?
Yes, Kemsing is one of the places we work. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Why is the stain in a different place from the leak?
Water rarely drops straight down. It can follow a timber or the underlay a long way first, so the entry point is frequently well away from the mark. That’s why we trace the route rather than patching above the stain.
Do you look in the roof space?
Where it is relevant to the survey and there is safe access, yes. A clear path to the hatch helps.
Are you structural engineers?
No. We point out what can be seen, like sagging or deflection, but we’re not structural engineers and do not carry out calculations. Where an engineer is needed, we say so in the report.
Do you test for asbestos?
No. Our report may flag materials that could contain asbestos, but only a specialist asbestos surveyor can confirm it. Buildings built or refurbished before 2000 may contain it.
Will you go up on the roof?
Not always. Safety comes first, and fragile or steep roofs cannot always be walked on. Safe viewpoints, the loft and a drone where applicable let us see the rest.
Tips that help
There’s plenty you can do without going near the roof. What helps most:
- Have an electrician check any wet fittings
- Clear the loft hatch so we can get in
- Check whether pipes or tanks run near the stain
- Let us know what has already been tried
Keep the report after the work is done. If water appears again, it shows what was found before, which makes the next step quicker.
Don’t block the vents at the eaves. Air movement keeps condensation down, which is often mistaken for a leak. Make sure insulation does not block airflow at the eaves.
Why act early in Kemsing
Water damage grows the longer it is left. Wet timbers start to decay, plaster softens and insulation stops working. Finding the source early keeps the damage down. Blocked gutters on homes around Kemsing overflow and soak walls, particularly where trees overhang. Dealing with the cause is simple; drying out a wall is not.
The Premium Survey includes thermal imaging and drone inspection where it applies, which starts from £400, including VAT. We can help you choose the package that fits what you want to find out.

How the survey changes by roof type
Parapet and box gutters
Some older terraces have a butterfly roof with a valley gutter in the middle. Problems there often show in the rooms on the top floor.
Chimney stacks
Water that gets in at the top can show up lower down. Unused flues with open pots can let rain straight in.
What affects the cost of roof leak investigations
To price your survey, we look at:
- Features like valleys, chimneys, dormers and parapets
- Extra roofs, like extensions, dormers or garages
- Whether it is a home or a commercial building
- The use of thermal imaging or a drone
There are three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, with VAT included. The price for your roof depends on its size, access and what you want to find out.

These details help when you get in touch:
- Any photos you have, taken from ground level or a window
