A careful look at the leaking roof at your property in Canonbury, with photos and a written report.

Why act early in Canonbury
A leak that returns after a repair normally means the real source wasn’t found. A careful investigation looks at every likely route, not just the obvious one. It gives the next repair a far better chance. Many older London roofs have only old felt under the slates, or no underlay at all, so a slipped slate can soon mean water inside. Left unchecked, water soaks into timber and plaster and the damage spreads.
We offer three survey packages: Basic from £150, Standard from £250 and Premium from £400, all inc. VAT. What your roof costs depends on its size, access and what you want to find out.

Roof leak investigation in Canonbury: what you get
Our job is to find the likely source and tell you. You get a report with photographs showing the likely entry point and the route the water is taking, plus recommendations on what needs attention. It gives any roofer a clear brief. The investigation finds and explains the cause, and the repair itself is a separate job. If you’ve noticed damp walls below an overflowing gutter and condensation that looks like a leak, we can find out what’s behind it.
In a London flat, water can travel some way before it shows, sometimes in a different flat from the one below the defect. Tracing it back matters, both for dealing with the cause and for any insurance claim. In Canonbury, we inspect what we can reach safely and are given access to. Let us know when the water shows, and in what kind of weather.
We write the report in plain English, so you don’t need to be a roofer to follow it. Photographs show what each point refers to, with the urgent items made clear.

Useful tips for Canonbury property owners
A survey works best with a little help from you, before and after. Some tips:
- Catch drips in a bucket and protect the floor
- Leave roof access to professionals
- Clear the loft hatch so we can get in
- Keep water away from lights and sockets
Any roofer you ask to quote can work from the report. The photos show the defects and where they are, rather than at the stain.
After a storm, check the roof from the garden and the street. Slipped slates, lifted ridge tiles and debris on the ground are signs to act on. Prompt repairs stop gaps turning into leaks.
How we price roof leak investigations
When we price a survey, we consider:
- The package you choose: Basic, Standard or Premium
- The use of thermal imaging or a drone
- How big the roof is
- How many separate roofs there are, such as extensions, dormers and garages
Prices quoted always include VAT, and the written report is part of the package. Our price is from £150, including VAT. Where your roof sits in the range depends on its size, height and access.
What we need to know
A little information up front helps. It helps to include:
- What’s prompted the survey
- Dates you’re working to, such as exchange
- The address and postcode of the property
- Any stains, drips or damp patches you’ve seen indoors
Every survey is priced before it is booked, so you know the cost up front. Prices start from £150, including VAT. To book, phone 07833 053749 or email us.
Roof leak investigations around Canonbury
Historic houses like Sutton House, about 1.7 miles east, show how far back building in the area around Canonbury goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. The covering and its details give the first clues when tracing where water is coming from.
Homes near green spaces like Shoreditch Park can get more leaves in their gutters in autumn. For landlords with property near Canonbury station, a tenant living with a leak needs the cause found, not just the stain painted over. Take a building like Rotherfield Primary School: water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.

Your questions about roof leak investigations in Canonbury
Do you carry out roof surveys in Canonbury?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Is my home in Canonbury listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
What will the report tell me?
You get our findings in writing, part by part, with photos, and ends with what we recommend. The most urgent items are made clear.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years, across London and South East England.
Will you check the loft?
Yes, where the survey calls for it and there is safe access. We look for staining, damp, daylight and signs of movement.
What insurance do you have?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
Why does not the damp patch line up with the hole?
Because water travels. It can follow a timber or the underlay a long way first, so the stain may be some distance from where it gets in. We follow the route back instead of guessing.
Surveys for landlords and agents in Canonbury
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait, which helps with budgets and planning.
Landlords, agents and building managers in Canonbury and across Greater London can book any of our surveys. To discuss a property or a block, phone 07833 053749 or send us an email.
What we do, step by step
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. All told, expect about one to two hours at a typical home, and more on a big or complicated roof. In a London area like Canonbury, the main things to sort out are parking and access: let us know about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at whatever is safely visible from ground level, windows, the loft and, where it’s safe, the roof itself.

What we look for on each type of roof
Chimney stacks
We look at the outside of the stack and the breast inside, not a flue, gas or sweep inspection.
Flat roof upstands and outlets
Each flat roof relies on its outlets to drain. A blocked outlet leaves water standing, which tests every joint. We check outlets and the covering around them.
