Swan Bottom: your questions answered
Is Swan Bottom in the area you cover?
Yes, Swan Bottom is within the area we cover. We work right across London and the South East. You can call 07833 053749 or use the contact form with the address and some details.
How do I find out if my home in Swan Bottom is listed?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material.
Does someone need to be in?
That depends on the survey. For inside areas and the roof space, someone has to give us access; we’ll agree the details when you book.
Will you definitely find the leak?
Not always, and we’ll be honest about that. Water can travel a long way, and some leaks only show in particular storms. If we cannot be sure, the report ranks the possible sources.
Do you carry out surveys on Saturdays and Sundays?
Visits run seven days a week in the daytime, which suits people who work during the week. Just say which days work for you.
How experienced are you?
More than 5,000 surveys over 20+ years.
Does this replace a RICS home survey?
No. Our survey looks at the roof, not the whole building. If you need a full building survey, you will need a RICS survey as well.
How a roof leak investigation works in Swan Bottom
On a flat roof, water can travel a long way under the covering. Splits, blisters, failed laps, worn upstands and blocked outlets are common causes. Standing water puts extra pressure on every weak point. We check the roof surface and the ceiling below to narrow it down. Leaks under flat extension, garage and dormer roofs are common. Felt often lasts around 15 to 20 years, so age is part of the picture. We survey valleys and parapet gutters, the roof space and rooflights and dormers, and the problems we are asked to look at most are damp patches next to the stack and water marks that spread in wet weather.
For a small place like Swan Bottom, the inspection is the same as anywhere: the journey and access are just planned in advance. It is useful to know where the water appears, in what weather, and what you’ve seen outside, plus any earlier repairs. Photos of the stain and of the roof from outside are helpful too.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

Checking the roof from the ground
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
Signs you need a roof leak investigation in Swan Bottom
Every flat roof covering has a working life. Felt frequently lasts around 15 to 20 years, and as it ages it splits, blisters and opens at the laps. Upstands and outlets are common weak points.
It is worth booking a survey if you’ve seen:
- Wet patches on loft insulation
- A leak that comes and goes with the weather
- Wet patches high on an inside wall
- Condensation that looks like a leak
Anyone responsible for a site like Lee Common Church of England School will know that tracing a leak on a big roof starts with where the water appears and works back.
What to check before booking
- What exactly goes into their report
- Is there a chance to talk the report through?
- What experience they bring
- What insurance they carry
What this survey cannot tell you
In fairness, a roof survey has limits:
- What’s under the covering or behind the plaster
- Carrying out the fix
- Plumbing leaks that look like roof leaks

Roof by roof
Slate and tile slopes
‘Nail fatigue’ is a common cause of slipped slates. One slipped slate can be enough to cause a leak.
Flat roof upstands and outlets
Flat roof water can travel under the covering before it shows. Where conditions allow, moisture readings and thermal imaging help narrow it down.
Before and after the survey
These tips come from what we see on roofs every week:
- Keep water away from lights and sockets
- Do not climb onto the roof to look
- Write down the wind direction and rain when it leaks
- Check the loft is accessible
Standard includes a follow-up consultation to talk the findings through, and Premium includes an in-person consultation. It’s a chance to ask about anything in the report.
Have flashings and flat roofs looked at every few years. Flashings, valleys and flat roof details are frequent weak points, and catching wear early keeps water out.
Wind, rain and roofs in Swan Bottom
Historic houses such as Cholesbury Manor House, about 2.1 miles north-east, show how far back building in the area around Swan Bottom goes. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. A number of Buckinghamshire villages keep thatched roofs on their older buildings. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. The covering and its details give the first clues when tracing where water is coming from.
If you let a flat or house near Great Missenden station, a tenant living with a leak needs the cause found, not just the stain painted over. If you own one of the older houses in the streets near Parish Church of St John the Baptist, the leak may come from a chimney, a valley or tired lead rather than the covering itself.

How the survey works
Every roof is different, but as a rough guide the survey takes roughly 1–2 hours, more where the leak is intermittent or the roof is large. You are welcome to ask questions while we’re there. In a hamlet or village like Swan Bottom, a postcode does not always lead to the right gate, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- You let us know where the water shows and when it appears.
- We look at the stain, the ceiling and the loft above it.
- Likely entry points outside are checked, from flashings and valleys to gutters and outlets.
- Where it helps, we take moisture readings and use thermal imaging.
- Your report sets out where the water is most likely getting in, with photos and recommendations.
Preparing for the visit
- Let us know about parking near the property
- Check the loft hatch can be reached
- For a flat or shared roof, check access with whoever owns or manages the building
