Barbican Estate: your questions answered
Is parking a problem for a survey in Barbican Estate?
It can be, so it helps to let us know about permits, visitor bays or off-street space when booking. That way the visit can be planned around it.
How do I find out if my home in Barbican Estate is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you’re planning to re-roof in a different material.
What happens after the survey?
The report comes by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
Will you walk on the roof?
Not always. Some roofs are too steep or fragile to walk on safely. Safe viewpoints, the loft and a drone where applicable let us see the rest.
How fast do I get the report?
Each package has its own report time. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. Mention any deadline as you book.
Is this a RICS survey?
No. This is a survey of the roof only, so it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
Which days do you carry out surveys?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Just let us know the days that suit you.
About our roof leak investigation in Barbican Estate
Flat roofs leak in their own ways. Common causes are splits and blisters, tired upstands and outlets that don’t drain. Standing water puts extra pressure on every weak point. We check both the covering and the room underneath. Flat roofs over extensions, garages and dormers are frequent sources of leaks. Felt often lasts around 15 to 20 years, so age is part of the picture. We survey rooflights and dormers, chimney stacks and lead flashings, and the problems we’re asked to look at most are water through the ceiling under a flat roof and staining around the chimney inside.
In London, leaks frequently start somewhere hidden: the valley gutter in a butterfly roof, a parapet gutter, a chimney flashing or the flat roof over a rear extension. For a leak or storm damage in Barbican Estate, those hidden details are where the inspection begins. A hidden gutter that overflows can send water a long way before it shows.
After the visit, you get a report with photos, emailed to you. It sets out the condition of the leaking roof, any defects and our written recommendations.

The survey, step by step
After the inspection, everything we found is written up in a report with photographs. As for time on site, most surveys take an hour or two for most homes, though a hard-to-trace leak can take longer. In Barbican Estate, visits are available on weekdays and at weekends. London parking is often by permit or pay-and-display, so it’s useful to know what’s near you. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- You pick a Basic, Standard or Premium Survey.
- A visit is booked for a weekday, Saturday or Sunday.
- We inspect inside and out, starting from the stain.
- Moisture detection and thermal imaging are used where your package includes them and they help.
- You get photos, the likely cause and clear recommendations.
Getting ready for the survey
- Move anything stored under the loft hatch
- Make a note of anything you’d like us to look at
- Mention any parking restrictions on your street
Booking a survey
Photos help, if you have them. Pictures from ground level or a window are fine; never climb up to get a better view. To get started, ring 07833 053749 or send us an email.

Useful tips for Barbican Estate property owners
You do not need to be a roofer to help. What helps most:
- Mention earlier attempts to fix the leak
- Have an electrician check any wet fittings
- Tell us if there are tanks or pipes in the loft
- Put a bucket under the drip and move valuables
Any roofer you ask to quote can work from the report. They’ll see exactly where the problem is, rather than at the stain.
Check the loft after heavy rain, with care and a good torch. Watch for water marks, wet underlay and damp wood. Take photos of anything that changes.
How the survey changes by roof type
Lead flashings
Wherever a roof meets a wall or stack, a flashing keeps rain out. Lifted, split or slipped lead is a common cause, and for flashings that have been patched with bitumen.
Valleys
A valley leak can appear well away from the valley inside. From inside the roof space, we follow the water’s route back.
Leaks and storm damage in Barbican Estate
With Mansion House about 0.5 miles south-east, Barbican Estate sits in an area with a long building history. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years. Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. Behind many of their parapets sit butterfly roofs and valley gutters that can’t be seen from the pavement. If your home in Barbican Estate is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. The covering and its details give the first clues when tracing where water is coming from.
Landlords with a home close to Moorgate station may find that a tenant living with a leak needs the cause found, not just the stain painted over. If your home is one of the older ones in the streets near St Giles-without-Cripplegate, lead flashings, valleys and old chimneys are typical places for water to get in. For site and facilities teams at buildings like Prior Weston Primary School and Children's Centre, on a building that size, finding the source of a drip means looking well beyond the stain.

What happens if roof problems are left?
Guesswork repairs are a common reason leaks keep coming back. Because water travels, the real entry point may be somewhere else. We find the probable source before anyone starts work. In a London terrace or conversion, a roof defect rarely stays your problem alone: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Dealing with it early is far less disruptive.
Every price we give includes VAT, and the report isn’t charged as an extra. Our price is from £150, including VAT. Where your roof sits in the range depends on its size, height and access.
