About our flat roof survey in Chelsea Harbour
A flat roof leak often travels before it shows on the ceiling. It may start at a split, a lifted seam or a failed upstand well away from the damp patch. Our survey covers the whole roof, not just the part above the mark, with photographs of anything that could be letting water in. Whoever carries out the work then has a clear starting point. We survey mastic asphalt, felt flat roofs and upstands and outlets, and people most frequently book us about a sagging deck under the covering and cracked or split membrane.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, and each fails in its own way. Which one is on a roof in Chelsea Harbour shapes how it is checked. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
Where we cannot see part of the flat roof, the report says so. You will know exactly what was inspected and what wasn’t, and what we’d suggest next.

Roof by roof
Single-ply membranes
Single-ply PVC and TPO membranes are common on commercial roofs and newer buildings. We check the welded laps, the edges, the fixings and any punctures.
Felt and built-up roofs
The edges and upstands of a felt roof are normally where trouble starts. We check each one and photograph any that have split or pulled away.
Can I check my roof myself?
Keep a simple record: dates of leaks, photos from ground level and any work done on the roof. Share it with us when you book.
A lot can be seen from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please do not climb up for a closer look.
Flat roofs in Chelsea Harbour
About 0.8 miles north-east lies Carlyle's House, a reminder of how long the area around Chelsea Harbour has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Chelsea Harbour has a number of hotels within about a mile and a half, 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.
Anyone responsible for a site like Chelsea Academy will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. If you look after a shop, office or commercial unit, for instance near Southside Wandsworth, a flat roof over a business is out of sight and out of mind until it leaks. Hotels and guest houses near Chelsea Harbour can’t easily close rooms for a leak, so it is worth knowing the roof’s condition.
Chelsea Harbour is about 2 miles south-east of Kensington, in Greater London.

How the survey works
The visit typically starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. All told, expect about one to two hours at most homes, with bigger or more complicated roofs taking longer. In a London conversion, the way into the roof 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 Chelsea Harbour runs like any other.
- 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’s access.
- The roof is inspected from every safe viewpoint, without walking on fragile surfaces.

Chelsea Harbour questions
Can parking be tricky for a visit in Chelsea Harbour?
It can be, so it helps to let us know about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Does a conservation area affect roof work in Chelsea Harbour?
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. 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.
Is ponding on a flat roof a problem?
Standing water on a flat roof deserves a closer look. It can point to blocked outlets, poor falls or a deck that is sagging, and it wears the covering faster. Our survey notes the ponding and what seems to be causing it.
What happens next?
You will receive the report by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Does a flat roof survey replace a RICS survey?
No. It’s a survey of the flat roof. It is not a RICS Level 2 or 3 home survey or a structural engineer’s report. Many buyers use it alongside a building survey.
Can you test old roof sheets for asbestos?
Asbestos testing is not part of our survey. If we see materials that could contain it, like cement sheets on a building from before 2000, we flag them so a specialist asbestos surveyor can check them.
Can you survey any kind of flat roof?
Felt, asphalt, EPDM, GRP and single-ply roofs are all covered. If you do not know what your roof is, we’ll identify it on the day.
Leave it or get it looked at?
A survey can show whether a whole new roof is needed or whether the problems are in a few places. Sometimes some details are to blame, and sometimes the covering has simply had its day. Our report gives you the evidence to discuss with a roofer. In Chelsea Harbour, as across London, an overflowing gutter soaks the wall below. A blocked outlet ignored for a winter or two can mean damp walls inside.
