Flat roof survey in Clapham, Greater London
Find out what’s going on with the flat roof before you spend money on it. Flat roof surveys in Clapham, with photos and a clear written report.
- Loose or cracked edge trims
- Outlets that hold water back
- Gaps at upstands and abutments
When to book a survey in Clapham
Ponding keeps the covering wet and wears it faster. Blocked outlets, poor falls and a sagging deck are the usual causes. Where trees are close by, leaves and silt can block an outlet within a single autumn.
It is worth booking a survey if you’ve seen:
- Signs of deflection in the roof deck
- Leaks around rooflights
- Raised blisters across the surface
- Splits and cracks in the covering
If you own a rental within reach of Clapham High Street station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Choosing a roof surveyor
- Their drone registration, if they fly one
- Are they insured for the work?
- What’s outside the scope of the survey
- Whether the loft is part of the inspection
How a flat roof survey works in Clapham
A Basic Survey, from £150, covers a visual inspection, a condition report, photos and written recommendations. The Standard Survey, from £250, adds moisture detection and a structural check. Moisture readings are useful on flat roofs, where water can spread under the covering before it shows inside. Bigger commercial roofs are priced on their size and access. If you’re worried about blocked or damaged outlets and leaks around rooflights, a survey will tell you what’s going on, whatever the roof.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in Clapham, the roof above may belong to the building rather than one flat.
The report doesn’t just list problems. For each finding, it explains what it is, why it matters and what we’d recommend.

What else we do in Clapham
Why act early in Clapham
Ponding seldom gets better on its own. Most frequently it means blocked outlets, poor falls or a deck that is dipping, and every wet spell adds to the wear. Knowing the cause early gives you more choice over what to do. In Clapham, as across London, an overflowing gutter soaks the wall below. A small blockage left for a few winters becomes a damp problem.
Our price is from £150, including VAT. What you pay depends on the size and height of the roof, how it can be seen safely and which survey you book.
Why book with us
- Drones and thermal imaging where it applies
- Visits on any day of the week
- Photographs and a written report every time

Flat roofs in Clapham
Within a mile and a half or so of Clapham there are several hotels, and hotels, like offices and blocks of flats, often have flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use. Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Next to the main roofs there’s normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If you run a hotel or guest house in or near Clapham, a roof problem can mean rooms out of use, so it is worth knowing the roof’s condition. If you run a business near Harrods, outlets and upstands on commercial flat roofs are the places to check before trouble starts.

- When you need the report by
- The property’s address and postcode
Booking is simple: just call 07833 053749 or send us an email and give us some details about the property and we will suggest the right survey. The price is agreed up front.
What we look for on each type of roof
GRP fibreglass
A GRP fibreglass roof is a hard, resin-bonded surface over a timber deck. We look for cracks at board joints, around trims and at upstands.
Felt and built-up roofs
The edges and upstands of a felt roof are normally where trouble starts. Every upstand and edge is looked at, with photos of any that have lifted or cracked.
Your questions about flat roof surveys in Clapham
Is parking a problem for a survey in Clapham?
It depends on the street. If Clapham has controlled parking where you are, a visitor permit is the easiest answer.
Does a conservation area affect roof work in Clapham?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Can you survey a flat roof on an office or unit?
Yes. We survey flat roofs on offices, shops, industrial units and blocks of flats. We quote bigger roofs on their size and how they’re reached, so phone 07833 053749 or email us with the address.
How long will you be at the property?
Expect it to take about one to two hours for most houses, with bigger or more complicated roofs taking longer. You’ll then get the report by email.
What does ponding on a flat roof mean?
Standing water a day or two after rain normally needs attention. The cause may be the outlets, the falls or the deck. We check each of these and record what we find.
I live in a flat. Can you survey the roof?
Yes, if the building owner or managing agent agrees access. On a shared roof we can only inspect the parts we are allowed to reach, and the report makes that clear.

What happens on the day
We photograph the roof as we go, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available. A typical visit takes about one to two hours for a house, with bigger or more complicated roofs taking longer. For a visit in Clapham, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at whatever is safely visible from the ground, windows, the loft and, where it is safe, the roof itself.
- You tell us about the roof, its covering if you know it, and any leaks.
- We look at the roof from wherever it can be seen safely.
- We check and photograph the covering, the falls, the upstands, the outlets, the trims and any rooflights.
- Where there’s safe access, we look at the ceilings and spaces below for signs of water.
- The findings are written up with photographs and recommendations and emailed to you.
How to prepare
- Make a note of anything you’d like us to look at
- Make sure pets are kept safely away
- For flats, make sure roof access has been agreed
