Flat Roof Survey in South Hampstead
Flat roof surveys across South Hampstead, with over 20 years’ experience behind it. Every survey ends with a written report and photos.
- A sagging deck under the covering
- Water getting in at rooflights
- Failed upstands where the roof meets a wall
What happens on the day
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. In total, it takes about 1–2 hours for a house, rising to roughly 3–4 hours on a commercial building. London terraces rarely offer a view of the whole roof from one spot, so a visit in South Hampstead moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, tell us who can let us into the shared parts.
- 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.
- We view the roof from safe positions and never walk 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

Advice
About our flat roof survey in South Hampstead
Our flat roof survey checks the waterproof covering and every detail around it, from edges and upstands to outlets and rooflights. We cover felt, mastic asphalt, EPDM rubber, GRP fibreglass and single-ply roofs. We survey extension, garage and dormer roofs as well as bigger roofs on flats, offices and units. You get a report with photos and our recommendations. Typical surveys look at damaged trims at the roof edge and splits, cracks and crazing, across single-ply membranes, EPDM rubber and felt flat roofs.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Every penetration and upstand is a place where a membrane can fail. In South Hampstead, roof access is agreed with the building manager or owner beforehand. Plant bases, rooflights and cable entries are all places where water can get in.
How fast the report arrives depends on the package: the Basic Survey within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey on the same day.

Common roof problems in South Hampstead
Buyers frequently book after their home survey suggests a closer look at a flat roof. Building owners and managing agents book to plan maintenance, or before a sale or a new lease. Either way, you get a clear record of the roof, with photographs.
Things that often lead to a survey include:
- A sagging deck under the covering
- Gaps at upstands and abutments
- Standing water left after rain
- Outlets that hold water back
Hotels and guest houses near South Hampstead cannot easily close rooms for a leak, so it’s worth knowing the roof’s condition.
Choosing a roof surveyor
- What follow-up you get after the report
- Whether the roof space is looked at, where there is one
- What insurance they carry
- Their report turnaround times
What this survey can’t tell you
It’s a careful look at the flat roof, not the whole story. The main limits are:
- The condition of the deck or insulation hidden under the covering
- Whether the deck or joists are strong enough
- Whether old sheeting or boards contain asbestos
If you’re not sure which survey you need, phone 07833 053749 or send us an email and we’ll give you a straight answer. The full list of what we check.
What we check
- Upstands and outlets
- Felt flat roofs
- Single-ply membranes
- GRP fibreglass
- EPDM rubber
- Mastic asphalt
Roof by roof
Single-ply membranes
On single-ply roofs, the welds between sheets are the key detail. We look at seams, corners and the joints around outlets and upstands.
Rooflights and upstands
The joins around rooflights and at upstands are common leak points. We check the seals and the covering around each one.
Should I look at the roof myself first?
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry, as it helps us focus the survey.
Flat and commercial roofs around South Hampstead
Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. 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. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Within a mile and a half or so of South Hampstead there are several hotels. If you look after one, a leak through a flat roof can put a room out of use.
Anyone responsible for a site like The UCL Academy will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. Shop and office owners around O2 Centre may find that the flat roofs over shops and commercial units are worth checking before a leak, not after.

FAQs for South Hampstead
Can you look at the flat roof of a hotel or office near South Hampstead?
Yes, commercial flat roofs are part of what we cover. For a bigger roof, you’ll get a quote based on the building, and roof access is agreed with you ahead of the visit.
Does a conservation area affect roof work in South Hampstead?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
Do you survey roofs on blocks of flats?
Yes, as long as access is agreed. The roof of a block or converted house is frequently shared, so we need permission from the freeholder or managing agent. We can only inspect what we’re given access to.
How long have you been surveying roofs?
Over 20 years and more than 5,000 surveys.
Is it a structural engineer’s report?
No. Our survey isn’t a structural engineer’s report. We will recommend an engineer if we see signs that call for one.
Which days do you carry out surveys?
We survey seven days a week: weekdays, Saturdays and Sundays. Just let us know the days that suit you.
Do you carry professional indemnity insurance?
We hold professional indemnity and public liability insurance.
