How a roof survey works in Keston
There is no single reason to have a roof surveyed. Some have seen a mark on a ceiling or bits of tile in the garden, while others just want to know where they stand. Whatever the reason, the survey works the same way: we inspect carefully and explain what we see in writing. We survey on weekdays and at weekends, so finding a time is rarely difficult. We survey lead flashings, natural slate and chimney stacks, and the problems we are asked to look at most are flashings that have come away from the wall and ponding, splits or blisters on flat roofs.
Many London terraces have a butterfly roof, with two slopes meeting in a central valley gutter that drains to the rear. Hidden behind the parapet, that gutter can block or split without anyone seeing it. For a house in Keston with this kind of roof, the hidden gutter is one of the first things to check.
What you get is a clear record of the roof on the day we saw it. It is useful right away, and a good reference for later.

Should I look at the roof myself first?
Your own check is a good start, but it isn’t a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.
You can learn a lot from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
What a roof survey doesn’t cover
Some things can’t be seen without opening up the roof, so a survey has limits:
- Walls, floors and services below the roof
- A structural engineer’s report
- How the roof will behave in every kind of weather
If you’re not sure which survey you need, phone 07833 053749 or email us and we’ll give you a straight answer. What a survey covers and doesn’t.
Roof types and parts we check

When to book a survey in Keston
Some damage starts inside the loft space. A badly ventilated loft collects condensation, wetting timbers and insulation. It is frequently mistaken for a leak, and it needs a different fix.
Typical things we are asked to look at include:
- Gutters that overflow in heavy rain
- Cracked mortar along the ridge
- Valley linings that have cracked or split
- Leaning or weathered chimney stacks
Living close to South Park is pleasant, but mature trees mean leaves in gutters and valleys each autumn.

FAQs for Keston
Will parking be an issue for a roof survey in Keston?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Are there drone restrictions around Keston?
That depends on where the roof is and on the weather. Keston is about 2 miles from Biggin Hill Airport, so the Drone Safety Map is checked for restrictions around it before we fly. Across London there are restriction zones around Heathrow, London City and London Heliport, plus restricted areas over Hyde Park, the City of London and the Isle of Dogs. Each address is checked against all of them before the drone goes up. The flight also waits for calm, dry weather.
Can you check whether my roof contains asbestos?
No. We do not carry out asbestos surveys or testing. Where materials might contain it, we say so in the report and recommend a specialist asbestos surveyor checks them before they’re disturbed.
Do you survey on Saturdays and Sundays?
Visits run seven days a week in the daytime. Let us know your preferred days when you book.
Is your survey a structural engineer’s report?
No. Where we see something that needs a structural engineer, the report says so. We do not provide structural calculations.
How soon is the report ready?
It depends on the package: within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium. It is emailed to you.
Does someone need to be in?
That depends on the survey. Inside the building and in the loft, we need someone to let us in.
How the survey changes by roof type
Clay plain and peg tiles
Tile-hanging on walls and dormer cheeks is checked as part of the roof where it is relevant. Gaps in tile-hanging let water reach the wall behind.
Natural slate
Inside the roof space, we check what’s under the slates. There may be old felt underlay, or none at all on very old roofs, and we note its condition.
What a roof survey looks like in Keston
Biggin Hill Airport is about 2 miles from Keston. Where the drone is part of the survey, the Drone Safety Map is checked for restrictions first. With Down House about 2.2 miles south-east, Keston sits in an area with a long building history. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead.
If you let a flat or house near Hayes (Kent) station, knowing the condition of the roof, chimneys and gutters helps you plan work rather than react to complaints. Anyone responsible for a site like Keston Church of England Primary School will know that its roofs, gutters and any chimneys need the same checks as a house’s, just on a bigger scale.

Helping us price your survey
To price your survey accurately, we will ask about:
- Where water is showing inside, if it is
- Where the property is, with the postcode
- Pictures from the garden or a window, if you have them
- The style of property, from a terrace to a block
If you have photos of the roof, send them over. Take them safely from ground level or a window; never climb up to get a better view. To send them or to book, ring 07833 053749 or use the contact form.
The survey, step by step
When we arrive, we begin with a quick chat about the roof and anything that’s worrying you. We then inspect everything that can safely be seen, from the ground, from windows, in the roof space and by drone where applicable. Most surveys take roughly 1–2 hours for an ordinary house roof, and longer if there are extensions, dormers or several chimneys. In a London area like Keston, the main things to sort out are parking and access: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. On the day, the roof is looked at from ground level, from windows, from inside the roof space and from the roof where it is safe.
- We help you choose a Basic, Standard or Premium Survey.
- We arrive at the agreed time and talk through any concerns.
- Coverings, ridges, hips, valleys, flashings, chimneys and gutters are inspected and photographed.
- Extra checks are carried out where your package includes them.
- The report is emailed with findings and recommendations.
Before the survey
- Buyers: confirm access with the estate agent or seller
- For a flat or shared roof, check access with the freeholder or managing agent
- Gather any invoices or paperwork from past roof work
