New roof snagging for homes and businesses in Cannon Hill
People book us after having a roof replaced or re-covered and some new-build owners want their roof looked at. Whatever the roof, we inspect as far as it can safely be seen including from the loft and the roof where it’s safe. A photo report follows, ready to share with your roofer or builder. If you’ve noticed signs of condensation in the roof space and underlay at the eaves left exposed, we can find out what’s behind it, on loft conversions and dormers, replacement roofs and new flat roofs alike.
London terraces and converted houses frequently share a roof line, chimney stacks and gutters with the house next door, with parapet walls and party-wall upstands marking where one roof ends and the next begins. That matters for anyone buying in Cannon Hill or checking a new roof there: only the parts we’re given access to and can see safely are inspected. If it’s a flat, the lease usually sets out who is responsible for the roof.
How fast the report arrives depends on the package: the Basic Survey within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey on the same day.

Surveys for landlords and agents in Cannon Hill
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.
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Tell us about it when you book and we’ll plan the survey around it.

Tips from our surveys
A little preparation and a few simple habits help. Some pointers:
- File all paperwork for the new roof
- Check ceilings and the loft after heavy rain
- Send the snagging report to your roofer
- Check the roof before you pay in full
After the snags are sorted, watch the roof in the next heavy rain. Raise any new signs of water with your roofer promptly.
Keep paperwork for the new roof together. The report belongs with them.
What we are asked to look at in Cannon Hill
Flashings are a common source of snags. If they’re poorly dressed or fixed, water can get in sooner rather than later.
Things that often lead to a survey include:
- Loose or badly finished ridge tiles
- Gutters or fascias damaged during the job
- Broken coverings left on a new roof
- Missing or blocked roof ventilation
If you own a rental within reach of South Merton station, a written report helps before buying a rental or paying for a new roof on one.
Before booking any roof surveyor

- Which limits apply to the survey

What happens on the day
We photograph the roof as we go, so you can see in the report what we found and where. We take close-ups from wherever is safe. A typical visit takes about 1–2 hours for a typical new house roof, longer where the roof is large or complicated. In a London area like Cannon Hill, the main things to sort out are parking and access: let us know about parking, the floor the property is on, any shared entrance and loft access. On the day, the roof is looked at from ground level, from windows, from inside the roof space and from the roof where it’s safe.
- We start by finding out what was replaced and what worries you.
- The coverings, ridges, hips and verges are checked as far as can be seen safely.
- We check valleys, flashings and gutters, and the underlay at the eaves where it’s visible.
- Where it’s safe, we check the loft, then look for debris or damage left behind.
- The snags are written up with photos for you to share with your roofer.
Before we arrive
- Tell us about parking before the day
- If the roof is shared, arrange access with whoever manages the building
- Make a note of anything you’d like us to look at

FAQs for Cannon Hill
Is my home in Cannon Hill listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Do you cover Cannon Hill?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
When should I book new roof snagging?
As soon as the work is finished, and before the final payment if you can. That gives time for any snags to be put right.
How do I book a survey in Cannon Hill?
Simply ring 07833 053749 or send us an email with the address. We’ll ask a few questions, confirm the price and agree a date, weekday or weekend.
Can you inspect the roof on a new-build home?
Yes. We check new-build roofs from safe vantage points and the roof space and photograph what we find. It is worth booking before your builder’s defects period ends.
How much time does a snagging visit need?
Most house visits take about 1–2 hours with commercial roofs nearer 3–4 hours.
Can you survey in bad weather?
Light rain is usually fine; heavy rain and wind are different. In strong wind or a downpour, a drone cannot fly and access may not be safe, and we’d agree another day.
Buying a home or a new roof in Cannon Hill
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. The covering on a house you’re buying, or on a roof just finished, tells us where to look hardest. The wider area around Cannon Hill has a long history of building, with Southside House about 1.2 miles north-west. On older houses around here, roofs often 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 your home is one of the older ones in the streets near St James Merton, ask the seller about past roof repairs, because older roofs often have patched valleys, replaced slates and reset ridges. For a London address like Cannon Hill, it helps to know about controlled parking before the day, along with any off-street space.

What’s near Cannon Hill
In Cannon Hill, that means homes and buildings near The Edward Rayne pub, Cannon Hill Common and Harris Academy Wimbledon and the streets around them. Cannon Hill’s nearest station is South Merton station, roughly 0.5 miles north-east of the centre. A little further out are St. Anthony's Hospital (1.5 miles south) and Wimbledon Museum (1.6 miles north). Open spaces near Cannon Hill include Cherry Wood and Henman Hill.
Can I check my roof myself?
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, which helps when we check the roof.
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can point to a blockage or a sagging run.
Why get it checked now?
Photos from ground level rarely show the detail. We get as close a view as safe access allows using a drone where it applies. Any roof job in Cannon Hill means planning around parking, neighbours and access. That is a good reason to find problems early, while there’s time to plan.
One thing that affects the price is the package: Basic from £150, Standard from £250 or Premium from £400, all inc. VAT. The roof’s size, height and access matter as well.
