About our flat roof survey in Blackfriars
Ponding is often the first sign that something on a flat roof isn’t right. It can point to poor falls, a blocked outlet or a deck that is deflecting. We record where water sits, check the outlets and look for dips that suggest deflection. If the deck itself looks like a structural concern, we’ll recommend a structural engineer. If you’re worried about ponding water that doesn’t drain away and outlets that hold water back, a survey will tell you what’s going on, whatever the roof.
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. In Blackfriars, roof access is agreed with the building manager or owner beforehand. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
The report is written in plain words, so you don’t need to be a roofer to follow it. Each point is backed by a photo where possible.

Roof by roof
Felt and built-up roofs
A felt roof frequently lasts around 15 to 20 years, though quality and upkeep make a big difference. Our report sets out its condition and the areas most at risk.
Mastic asphalt
Without seams, asphalt tends to fail through cracking and at its skirtings. Our report notes crazing, cracks and any likely entry points.
Prices for flat roof surveys in Blackfriars
What a survey costs depends on the time and equipment it needs. That comes down to:
- Whether thermal imaging or a drone is needed
- How tall the building is and how easy the roof is to see
- Basic, Standard or Premium
- Roof area
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before booking.
Helping us price your survey
The more you let us know, the easier it is to price the survey. When you get in touch, it is useful to mention:
- Where the property is, with the postcode
- Where water is showing inside, if it is
- Pictures of the roof from a safe spot, if you have them
- What made you get in touch
Not sure which survey you need? The easiest way is to call 07833 053749 or use the contact form and describe the roof and what’s worrying you. We will talk you through the options and what they cost.
Why act early in Blackfriars
Caught early, a split or open seam in a flat roof is frequently a small repair. Left alone, water can soak the insulation and the deck, and the job grows. A survey now shows which you’re dealing with. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. When the stain finally shows, the damage underneath is frequently older than it looks.
To find out what your survey will cost, call 07833 053749 or use the contact form and tell us about the roof. The price is agreed before a date is set.

Landlords, agents and block managers in Blackfriars
Freeholders and residents’ companies use a roof report to plan and budget, with the most urgent items set out first.
Businesses and commercial landlords can book us too. Bigger roofs take more time.
What happens on the day
Where it is relevant and can be reached safely, the loft space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. All in, the survey usually takes an hour or two at a typical home, with bigger or more complicated roofs taking longer. For a visit in Blackfriars, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. On the day, the roof is looked at from ground level, from windows, from inside the loft space and from the roof where it is safe.
- 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.
- 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.
Getting ready for the survey
- Have any paperwork from past roof work to hand
- Make a note of anything you’d like us to look at
- Make sure pets are kept safely away

Advice
Blackfriars: your questions answered
Is my home in Blackfriars 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. 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 parking a problem for a survey in Blackfriars?
Sometimes, yes. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well, and a driveway is even better.
Which flat roof coverings do you cover?
We survey felt and built-up roofs, mastic asphalt, EPDM rubber, GRP fibreglass and single-ply PVC and TPO. If you don’t know what your roof is, we will identify it on the day.
What happens next?
You will receive the report by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
Should I worry about standing water on my flat roof?
Standing water on a flat roof deserves a closer look. It often means a blocked outlet, poor falls or a dipping deck, and it wears the covering faster. Our survey notes the ponding and what seems to be causing it.
Do you take photos of the roof?
Yes. We photograph the roof as we go, and the report uses them to show each finding alongside our recommendations.
Do you give a life expectancy for the roof?
A precise figure isn’t something we give, because it depends on upkeep, weather and how the roof was laid. Our report describes the condition and what needs doing, and when.
What a flat roof survey looks like in Blackfriars
Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. If your home in Blackfriars is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops. With Dr Johnson's House about 0.2 miles north-west, Blackfriars sits in an area with a long building history. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area.
If you look after a building such as Mercers' School, a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail. If you run a business near Gabriel's Wharf, outlets and upstands on commercial flat roofs are the places to check before trouble starts. For an older house near a landmark such as St Ann Blackfriars, the flat roofs on later extensions tend to wear out long before the main roof.

DIY checks: what’s safe
Your own check is a good start, but it is not a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground, and those are details a survey looks at closely.
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it.
