How new roof snagging works in Canonbury
Building work can leave a mess behind. We look for broken tiles, offcuts and nails left in gutters and on lower roofs, and for damage to other parts of the building. It is all recorded with photos. Gutters full of offcuts can overflow in the next heavy rain, and cracked lower roofs can leak. Finding these early makes them easier to raise. We’re frequently asked to look into signs of condensation in the roof space and flashings not properly dressed or fixed, on flashings and valleys, new flat roofs and ridges and verges.
Many London homes have been converted into flats, extended at the back or given a loft conversion with a dormer. Each change adds roof details, like flat roofs, new flashings and junctions with the original slopes. If you are buying a flat or house in Canonbury, or have just had new roofing work done, those junctions are frequently where problems start. Dormer cheeks, lead work and new flat roofs are worth checking closely, as faults there are easy to miss.
Where we cannot see part of the new roof, the report says so. That way, it is clear what was covered and what wasn’t, and what we’d suggest next.

Can I check my roof myself?
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Look up at the roof after a storm, from ground level: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.

New roof snagging around Canonbury
Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. Behind many of their parapets sit butterfly roofs and valley gutters that cannot be seen from the pavement. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. For a purchase or a newly finished roof, the materials decide which details matter most. Sutton House, about 1.7 miles east, is one of the historic houses in the wider area around Canonbury. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material.
If you own a rental within reach of Canonbury station, a written report helps before buying a rental or paying for a new roof on one. If you live in an older home near St Paul's Church, older patch repairs can hide behind a tidy front slope, and the survey looks past them. For a London address like Canonbury, it helps to know about controlled parking before the day.

Canonbury: your questions answered
How do I find out if my home in Canonbury is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Do you cover Canonbury?
We do. The survey and report are the same in Canonbury as anywhere else, and visits run on weekdays and weekends.
Do you lift tiles to check the fixings?
No. We inspect what can be seen without opening up the roof so hidden fixings aren’t visible to us. We note what couldn’t be seen.
Will you check the loft?
If it is needed and safe to reach, yes. We look for staining, damp, daylight and signs of movement, as far as the space allows.
Can you inspect the roof on a new-build home?
Yes, new-build roofs are checked in the same way as replacement roofs. The report lists snags with photographs to raise with the builder.
Will you fly a drone over my roof?
Yes, where it’s applicable. Flights depend on the weather on the day and airspace rules. We hold a CAA Flyer ID and Operator ID.
Will you go up on the roof?
Only when it’s safe. Safety comes first, and fragile or steep roofs cannot always be walked on. We use safe viewpoints, the roof space and a drone where applicable.

What else we do in Canonbury
What happens on the day
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes roughly 1–2 hours for most homes, depending on how much new work there is to check. If you have questions on the day, just ask. From the street, a London terrace normally shows only its front slope or parapet, so in Canonbury we work round the house, using the street, the windows, the loft and any safe vantage point behind it. Shared stairs or a basement flat? Let us know who holds the keys.
- We agree what to focus on, such as a payment date or a warranty period ending.
- The roof is inspected from the ground, vantage points and the roof where safe.
- We work through ridges, verges, valleys and flashings.
- We check the gutters, lower roofs and walls for debris or damage.
- You receive a report to share with your roofer.
How to prepare
- Buyers: confirm access with the estate agent or seller
- Let us know about parking near the property
- Make sure we can get to the back of the property

Roof by roof
Flashings
Flashings around chimney stacks are a common weak point and are checked closely.
Underlay and ventilation
Vents at the ridge, eaves or in the tiles help keep the loft space dry. We check for vents where they’ve been fitted.
Before and after the survey
These tips come from what we see on roofs every week:
- File all paperwork for the new roof
- Check the roof before you pay in full
- Diary the defects period end date
- Watch for drips in the roof space with care
You receive a written report with photos of each snag and recommendations, prioritised by urgency where relevant. You can send it straight to your roofer.
Agree the snagging inspection with your roofer before the job starts. It sets clear expectations and time is set aside for snags.
What we can’t see
Without opening up the roof, some things stay hidden, so a survey has limits:
- Estimates of what fixes will cost
- How the roof will perform for years to come
- What’s under the new coverings
If in doubt, ring 07833 053749 or send us an email and we’ll point you to the right survey. The full list of what we check.
