Blackwall Flat Roof Survey
Flat roof surveys in Blackwall from an independent, experienced roof surveyor. More than 20 years and over 5,000 surveys.
- Failed upstands where the roof meets a wall
- Dips that suggest the deck is deflecting
- Splits and cracks in the covering
What we look for on each type of roof
EPDM rubber
Lifting at the edges and loose areas of membrane are common EPDM problems. We record any we can see, with photographs.
Felt and built-up roofs
Built-up felt is one of the most common flat roof coverings on extensions, garages and dormers. We look for blistering, cracking, split laps and worn mineral surfacing.
About our flat roof survey in Blackwall
Our Basic Survey, from £150, gives you a visual inspection with photographs and written recommendations. For moisture detection and a structural check, the Standard Survey starts from £250. Moisture readings are useful on flat roofs, where water can spread under the covering before it shows inside. Larger commercial roofs are quoted for their size. We survey single-ply membranes, GRP fibreglass and mastic asphalt, and people most frequently book us about loose or cracked edge trims and outlets choked with leaves and silt.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Each pipe, upstand and fixing through the covering is a possible weak point. For a building in Blackwall, access is agreed with whoever manages the roof ahead of the visit. Plant bases, rooflights and cable entries are all places where water can get in.
We keep jargon out of it: where something needs attention, it says so plainly, and where it can wait, that is said too.

Do you need a flat roof survey in Blackwall?
Water that does not drain sits on the roof and speeds up wear. It usually comes from poor falls, a blocked outlet or a deck that has dipped. Where trees are close by, leaves and silt can block an outlet within a single autumn.
Signs worth acting on include:
- Upstands pulling away from walls
- Loose or cracked edge trims
- Blisters and bubbles in the covering
- Outlets choked with leaves and silt
For an older house near a landmark such as All Saints Church, flat-roofed rear additions and dormers added over the years are worth checking.
Questions to ask before booking

Flat roofs in Blackwall
Blackwall 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. 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. 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.
For landlords with property near Canary Wharf station, the flat roof over a let home is worth a look before it becomes a tenant complaint. Anyone responsible for a site like Woolmore Primary School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Blackwall is about 1 mile south-west of Canning Town, in Greater London. We carry out flat roof surveys for homeowners, landlords and businesses in Blackwall. Our area takes in places right across Greater London, from the larger towns to small villages.

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. Most surveys take roughly 1–2 hours for most houses, and more on a big or complicated roof. For a visit in Blackwall, parking and access are the things to plan: let us know about parking, the floor the property is on, any shared entrance and loft access. We then look at what can be seen safely from ground level, windows, the loft and, where it’s safe, the roof itself.
- We start with the details: the address, the roof’s use and any leaks or stains.
- We view the roof from the ground, from windows and from the roof where it is safe to do so.
- Every part of the roof we can see is checked: covering, falls, upstands, outlets, trims and rooflights.
- We check the rooms or spaces under the roof for staining where we can reach them.
- We send a written report with photos, the defects we found and what we recommend.
How to prepare
- Have keys ready for side gates, garages or roof access doors
- Keep pets out of the way during the survey
- Buyers: confirm access with the estate agent or seller

Related advice
Why act early in Blackwall
Waiting for a stain inside means the water has already got through the layers. A survey can find worn areas and failing details before that point, while there’s still time to plan the work. 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.
Prices start from £150, with VAT included, for a Basic Survey. The Standard Survey starts from £250 and the Premium Survey from £400, both inc. VAT. You will know the price for your roof before booking.

What else we do in Blackwall
Before and after the survey
There’s plenty you can do without going near the roof. Here’s what helps most:
- Keep records of when the roof was laid and what work has been done
- Look for standing water a day after rain
- Treat rooflights and old sheeting as fragile
- Keep people off the roof unless they need to be there
You can use the report to ask roofers to quote for the same work. Because everyone is pricing the same findings, the quotes are easier to compare. It is your choice who carries out the work and when.
Clear leaves and silt from outlets and gutters, above all in autumn. A flat roof that drains well wears much more slowly.
Your questions about flat roof surveys in Blackwall
Is my home in Blackwall listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Can you look at the flat roof of a hotel or office near Blackwall?
Yes, we cover commercial roofs as well as homes. Roof access is agreed with the building manager or owner beforehand.
Can you survey in bad weather?
Light rain does not usually stop a survey, and it can even help show where water is getting in. Heavy rain or strong wind can ground a drone and make the roof unsafe, so we’ll agree a new date if the weather is not suitable.
How do I book a survey in Blackwall?
Just ring 07833 053749 or send us an email with the address. We will ask a few questions, confirm the price and agree a date, weekday or weekend.
I live in a flat. Can you survey the roof?
Yes, as long as access is agreed. The roof of a block or converted house is frequently shared, so the building owner or managing agent needs to agree access. We can only inspect what we’re given access to.
Will I get photos?
Yes. The report includes photographs of what we found, so you can see each point for yourself.
How soon will I get the report?
It depends on the package: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. Reports are sent by email.
