How a flat roof survey works in Westerham
Ponding is frequently the first sign that something on a flat roof isn’t right. It can mean the falls were never right, an outlet is blocked or the deck has started to sag. We record where water sits, check the outlets and look for dips that suggest deflection. If the deck itself looks like a structural concern, we will recommend a structural engineer. We survey mastic asphalt, GRP fibreglass and EPDM rubber, and the problems we are asked to look at most are ponding water that doesn’t drain away and failed seals around rooflight kerbs.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, each with its own weak points. In Westerham, as anywhere in London, the right approach depends on what the roof is made of. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
The report is written in plain words, so you don’t need to be a roofer to follow it. Each point is backed by a photograph where possible.

DIY checks: what’s safe
During heavy rain, look at the gutters from ground level or a window. Overflowing water can point to a blockage or a sagging run.
The one thing to avoid is getting up close. Roofs are fragile and slippery, and a fall can be serious. That’s where a survey comes in, using safe viewpoints and a drone where it applies.
Surveys for landlords and agents in Westerham
If you own several properties, surveys can be booked for more than one address. To discuss a number of properties, call 07833 053749 or send us an email with the addresses.
Surveys can also be booked by buyers’ agents acting for a client. The report is emailed, so it can go straight to your client, photographs included.
What we look for on each type of roof
EPDM rubber
An EPDM rubber roof is normally one large sheet, bonded to the deck. We check the laps, the edges, the corners and any punctures.
Rooflights and upstands
Rooflights, lanterns and upstands are where many flat roof leaks begin. We check the seals and the covering around each one.

Why act early in Westerham
If you are buying, find out about the flat roof before you exchange. After that, the cost of any work is yours. A report gives you facts to put to the seller or agent. Blocked gutters and hoppers on London houses overflow and soak brickwork. A blocked outlet ignored for a winter or two can mean damp walls inside.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. Our price is from £150, including VAT.
What you get with us

Local flat roofs in Westerham
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. The wider area around Westerham has a long history of building, with Quebec House about 0.2 miles south-east. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first.
If yours is one of the older homes in the streets near Church of St Mary the Virgin, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. Westerham is in London, so parking needs planning: a visitor permit or a nearby bay makes the day easier. Landlords with a home close to Hurst Green station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Westerham is about 5 miles west of Sevenoaks, in Greater London. Whether the building in Westerham is a house, a flat or a commercial unit, we can survey the roof. Westerham is one of the places in Greater London where we work. For surveys nearby, see our Crawley page.

What affects the cost of flat roof surveys
What a survey costs depends on the time and equipment it needs. The main factors are:
- The use of thermal imaging or a drone
- Roof area
- Commercial roofs and larger buildings
- The package you choose: Basic, Standard or Premium
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You will know the figure before booking.
Getting in touch
To price your survey accurately, we will ask about:
- Where any leaks, stains or damp patches show inside
- The property’s address and postcode
- What made you get in touch
- Pictures of the roof from a safe spot, if you have them
Not sure which survey you need? The easiest way is to ring 07833 053749 or send us an email and describe the roof and why you want it surveyed. We’ll explain the options and the price.
Common questions in Westerham
Is Westerham in the area you cover?
Yes, Westerham is one of the places we work. The survey and report are the same in Westerham as anywhere else, and visits run on weekdays and weekends.
Does a conservation area affect roof work in Westerham?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do I need to be at home?
It depends on what we need to see. For inside areas and the loft space, someone has to give us access, while outside access can be discussed when you book.
Which days do you carry out surveys?
Surveys run on weekdays, Saturdays and Sundays. To arrange a date, ring 07833 053749 or email us.
How do I arrange a flat roof survey in Westerham?
Simply ring 07833 053749 or drop us an email with the address. We will ask a few questions, confirm the price and agree a date, weekday or weekend.
Is a flat roof survey the same as a building survey?
No. It’s a closer look at the flat roof, not a survey of the whole property. It complements a RICS home survey rather than replacing it, and structural calculations need a structural engineer.
Does the report include photos?
Yes, plenty. Each finding is shown in a picture where possible, which makes the report easy to follow.
How the survey works
A survey visit follows a simple order: we hear what you’ve seen, look at the roof from every safe viewpoint, photograph what we find and make notes for the report. Most visits take an hour or two for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. In a London conversion, the way into the loft space is often from a communal landing or the top flat. Where that’s the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Westerham runs like any other.
- We start with the address and, on larger roofs, the roof area and access.
- Inside, we look for signs of water under the roof where we can reach.
- The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
- We record every defect with a photo and its likely cause.
- The report explains the condition and recommends what to do first.
Before we arrive
- Agree roof access with the managing agent if it’s shared
- Note where any stains or damp appear
- Jot down any questions you want answered
