Flat roof surveys for homes and businesses in Chelsea
Flat roofs deal with rain in a very different way from pitched ones. Water lies on the surface for longer, so a small split or a blocked outlet can soon lead to a leak. The surface, the falls, the upstands and the trims are all looked at closely, and we note any sign that the deck below has got wet. The aim is to find problems before they show up as a stain on a ceiling. Common reasons to book are damaged trims at the roof edge and blistering in felt or asphalt, on GRP fibreglass, upstands and outlets and felt flat roofs.
Offices, shops and blocks of flats across London frequently have large flat roofs with plant, rooflights and walkways. Every penetration and upstand is a place where a membrane can fail. For a building in Chelsea, access is agreed with whoever manages the roof before the visit. Plant bases, rooflights and cable entries are all places where water can get in.
What you get is a clear record of the flat roof on the day we saw it. That makes it useful now and a handy reference later, such as when you want to compare after future work.

Tips from our surveys
Getting the most from a flat roof survey starts before we arrive and carries on afterwards. Tips:
- Watch the ceilings below the flat roof for stains
- Keep people off the roof unless they need to be there
- Make sure new fixings through the roof are properly sealed
- Clear roof outlets and gutters each autumn
Many people send the report to two or three roofers for quotes. Because everyone is pricing the same findings, the quotes are easier to compare. You stay in control of who does the work and when.
Check the roof from a window after a downpour. Water still lying a day or two later is worth getting looked at.

How the survey works
When we arrive, we start by asking what you’ve noticed and what you need to know. We then inspect everything that can be seen safely. The survey typically takes about one to two hours for a house; commercial roofs usually need 3–4 hours. From the street, a London terrace typically shows only its front slope or parapet, so a visit in Chelsea moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, let us know who can let us into the shared parts.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- We check the rooms or spaces under the roof for staining where there is access.
- The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
- We record every defect with a photo and its likely cause.
- You get a report setting out the condition and our recommendations, in order of urgency.
Preparing for the visit
- Have any paperwork from past roof work to hand
- If you are buying, let the agent know when we are coming
- Check the loft hatch can be reached

Checking the roof from ground level
A lot can be seen from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, as it helps a surveyor trace the cause.
Honest limits
This isn’t a RICS building survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Testing older roof sheets for asbestos
- The condition of the deck or insulation hidden under the covering
- An exact number of years the roof has left
Not sure which survey suits your roof? You can phone 07833 053749 or use the contact form and we’ll tell you before you book. What a survey covers and doesn’t.
Roof types and parts we check
- Single-ply membranes
- EPDM rubber
- GRP fibreglass
- Mastic asphalt

Common questions in Chelsea
Can parking be tricky for a visit in Chelsea?
Sometimes, yes. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well, and a driveway is even better.
Is my home in Chelsea listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Are you insured?
Our cover is professional indemnity plus public liability, and details are available on request.
Do you survey commercial flat roofs?
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 please ring 07833 053749 or drop us an email with the details.
What’s the best way to book?
To book, ring 07833 053749 or email us with the address, the type of property and what’s prompted the survey. We will confirm the price and agree a day with you.
How many years has my flat roof got left?
A precise figure isn’t something we give, because it depends on upkeep, weather and how the roof was laid. We describe the condition and say which work is urgent and which can wait.
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, while outside access can be discussed when you book.
Prices for flat roof surveys in Chelsea
The price reflects the time and kit the roof needs. That comes down to:
- Whether thermal imaging or a drone is needed
- Which survey package you book
- The type of building, from a house to a block or an office
- How tall the building is and how easy the roof is to see
We offer three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, with VAT included. What your roof costs depends on its size, access and what you want to find out.
What to tell us when you get in touch
We’ll usually ask about:
- Photos of the roof, taken safely from the ground or a window
- Your timetable, like an exchange date
- The style of property, from a terrace to a block
- Access details, like a loft hatch or a shared roof
Most bookings start with a short call: call 07833 053749 or send us an email. You’ll have a price before anything is arranged.
Why get it checked now?
A small split in a flat roof is normally a modest job when it’s found early. Leave it, and water can get into the insulation and deck, which can turn a patch into a replacement. Surveying it now tells you where you stand. London’s older roofs often have bitumen felt underlay or none at all, so a slipped slate can soon mean water inside. Left unchecked, water soaks into timber and plaster and the damage spreads.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Our price is from £150, including VAT.

Flat roofs in Chelsea
About 0.4 miles south-west lies Carlyle's House, a reminder of how long the area around Chelsea has been built on. If your home is one of 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. Many homes in inner London are Victorian and Edwardian terraces, frequently with Welsh slate roofs. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
For businesses in and around places such as Harrods, flat roofs over shops and units are easy to forget until water comes through a ceiling. If you run a hotel or guest house in or near Chelsea, a roof problem can mean rooms out of use, so it is worth knowing the roof’s condition. For site and facilities teams at buildings like Oratory Roman Catholic Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
