About our flat roof survey in Stockwell
Our flat roof survey checks the waterproof covering and every detail around it, from edges and upstands to outlets and rooflights. Felt, asphalt, EPDM, GRP and single-ply PVC or TPO roofs are all part of the work. We survey extension, garage and dormer roofs as well as bigger roofs on flats, offices and units. The findings go into a written report with photos, setting out the defects and what we’d recommend. Common reasons to book are outlets that hold water back and blistering in felt or asphalt, on upstands and outlets, EPDM rubber and mastic asphalt.
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 block or conversion in Stockwell, the flat roof is often a shared part of the building.
Every survey ends with a written report, with photographs, sent by email. It sets out the condition of the flat roof, any defects and our written recommendations.

What happens on the day
We check the roof from outside and, where it is relevant and there’s safe access, from inside the roof space too. In the loft, the signs we look for are staining, damp, daylight and sagging. The whole visit usually takes roughly 1–2 hours for a small flat roof at home, and longer for a large commercial one. Surveys in Stockwell can be booked for any day of the week. It helps if you can point us to a visitor permit or a nearby bay. Upstairs rooms at the back are useful too, as they frequently give the best view of a rear addition.
- We start with the address and, on larger roofs, the roof area and access.
- We check the rooms or spaces under the roof for staining where there’s access.
- 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
- Check we can get to the back of the property
- Gather any invoices or paperwork from past roof work
- Buyers: confirm access with the estate agent or seller

Prices start from £150, including VAT. What you pay depends on the roof’s size, access and the package, so phone 07833 053749 or send us an email with the details.

Flat roof surveys around Stockwell
There are several hotels within about a mile and a half of Stockwell. If you look after one, a leak through a flat roof can put a room out of use. Inner London’s Victorian and Edwardian terraces often have Welsh slate roofs. Behind many of their parapets sit butterfly roofs and valley gutters that cannot be seen from the pavement. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
Carlyle's House, about 2.4 miles north-west, is one of the historic houses in the wider area around Stockwell. If your home is older, its flat-roofed extension or dormer may be on its second or third covering. For businesses in and around places like Gabriel's Wharf, flat roofs over shops and units are easy to forget until water comes through a ceiling.
Stockwell is about 2 miles south-west of London, in Greater London. We visit Stockwell as part of our work across Greater London. We cover towns and villages across Greater London.

What we are asked to look at in Stockwell
A flat roof lies open to sun, rain and frost, and water drains off it slowly. Over the years, coverings harden, crack and start to come away at the edges. Most people book a survey after a leak, before buying, or when they think the roof is getting old.
A survey can pick up problems such as:
- Blistering in felt or asphalt
- Damaged trims at the roof edge
- Dips that suggest the deck is deflecting
- Outlets that hold water back
For hotels and guest houses around Stockwell, a roof problem found early is far less disruptive than one found by a guest, so it’s worth knowing the roof’s condition.
Questions to ask before you book
- Do they have a CAA Flyer ID and Operator ID for drone work?
- What experience they bring
- When you will get the report
- How they’ll see the roof: from ground level, the loft, the roof or by drone
DIY checks: what’s safe
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can point to a blockage or a sagging run.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Share it with us when you book, as it helps us focus the survey.
What this survey can’t tell you
It’s a careful look at the flat roof, not the whole story. The main limits are:
- Fragile surfaces, which we do not walk on
- An exact number of years the roof has left
- Whether the deck or joists are strong enough
Not sure which survey suits your roof? You can call 07833 053749 or email us and we will tell you. What our survey covers.
Roof types and parts we check
- GRP fibreglass
- EPDM rubber
- Single-ply membranes
- Mastic asphalt
- Felt flat roofs
- Upstands and outlets
Roof by roof
Single-ply membranes
Many offices, units and newer flats have a single-ply PVC or TPO roof. The survey looks at welded seams, edges, fixings and signs of damage.
Mastic asphalt
With age, asphalt can harden and crack with movement. We note where this is happening and how widespread it looks.
Common questions in Stockwell
Is parking a problem for a survey in Stockwell?
Parking in Stockwell, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
How do I find out if my home in Stockwell is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
How do I book a survey in Stockwell?
Just phone 07833 053749 or drop us an email. After a few questions, we confirm the price and fix a day.
Can you survey a shared roof?
Yes. Shared roofs just need a little more planning, with whoever owns or manages the building. Let us know about it when you book and we’ll plan the survey around it.
Does a flat roof survey replace a RICS survey?
No. It is a survey of the flat roof. It isn’t a RICS Level 2 or 3 survey of the whole building, and it is not a structural engineer’s report. Many buyers use it alongside a building survey.
Do I have to be there for the survey?
That depends on the survey. For inside areas and the loft space, someone has to give us access.
Does the survey cover asbestos?
Asbestos testing isn’t part of our survey. If we see materials that could contain it, such as cement sheets on a building from before 2000, we flag them and recommend a specialist asbestos surveyor.
