Roofs, chimneys and gutters in Cannon Hill
Southside House, about 1.2 miles north-west, is one of the historic houses in the wider area around Cannon Hill. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years. Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Each of these coverings has its own weak points, from fixings and valleys to flashings, chimneys and gutters.
Anyone responsible for a site like Hillcross Primary School will know that large buildings have long gutter runs and big roofs that need checking like any other. Trees in and around Cannon Hill Common shed leaves that can end up in nearby gutters. The streets around a church such as St James Merton are often among the oldest in a place, and if yours is one of the older homes nearby, its roof may have old fixings, lead flashings and chimneys that need a closer look.

Chimney survey in Cannon Hill: what you get
Many terraced and semi-detached homes share their chimney stacks with a neighbour. We inspect the parts we can see safely and the parts the owner gives us access to. If a defect appears to be on the neighbour’s side, we note it and you can then discuss it with them. Everything is written up with photos and what we recommend. We are often asked to look into eroded joints in the brickwork and lifted or split lead flashings, on brick chimney stacks, lead flashings and shared and party-wall stacks.
Victorian and Edwardian terraces are found right across London, often with slate roofs, chimney stacks shared with neighbours and gutters hidden behind parapets. Slates can last a century or more, but the nails holding them corrode, and slates slip. Homes in Cannon Hill are no exception. Lead flashings and shared chimney stacks on these houses need a proper look too.
Pictures do a lot of the work in our reports, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

Honest limits
Without opening up the roof, some things stay hidden, and that sets some limits:
- Whether a gas appliance or its flue is safe
- The inside of the flue, which needs a sweep or flue specialist
- Hidden damage within the stack
If in doubt, call 07833 053749 or send us an email and we will point you to the right survey. What a survey covers and doesn’t.

Roof by roof
Flaunching
We often find flaunching that has cracked or broken away. It is normally a modest repair when it is caught early.
Chimney pots and cowls
For unused flues, we check whether caps or cowls allow ventilation. Capping without ventilation can trap moisture.
How we price chimney surveys
When we price a survey, we consider:
- How tall the building is and how easy the roof is to see
- House, block, shop or office
- How complicated the roof is, with its valleys, chimneys and parapets
- The package you choose: Basic, Standard or Premium
The Premium Survey includes thermal imaging and drone inspection where it applies, which starts from £400, with VAT included. We will tell you which package suits the questions you have.
What to tell us when you get in touch
You do not need to know any roofing terms. It is enough to tell us:
- Pictures from the garden or a window, if you have them
- The address and postcode of the property
- What made you get in touch
- Any stains, drips or damp patches you’ve seen indoors
Our price is from £150, including VAT. The exact figure depends on the roof and the package, so call 07833 053749 or send us an email with the details.
Surveys for landlords and agents in Cannon Hill
If you own several properties, surveys can be booked for more than one address. To discuss a number of properties, phone 07833 053749 or drop us an email.
A roof problem in a let property affects your tenants as well as the building. A survey helps you spot issues early and plan the work around your tenants.

How it works
On the day, we start by asking what you’ve noticed and what you need to know. After that, we check everything we can see safely, using the ground, windows, the loft and a drone where applicable. Most surveys take roughly 1–2 hours for a house, and about three to four hours for a commercial roof. For a visit in Cannon Hill, 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.
- You tell us how many stacks there are and any damp or problems you’ve noticed.
- Each chimney is viewed from wherever it can safely be seen.
- We check and photograph the pots, cowls, flaunching, pointing and flashings.
- Where there is safe access, we look at the stack in the loft and the chimney breasts for damp.
- You get a written report with photos and our recommendations.
Before the survey
- Mention any parking restrictions on your street
- Keep pets in another room
- Have keys ready for side gates, garages or roof access doors
Book a survey
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. For any other survey, just ring 07833 053749 or use the contact form when you’re ready.
Advice
Tips from our surveys
Nothing here needs a ladder. Our suggestions:
- Keep track of stains on chimney breasts
- Check fixings on the stack are secure
- Check with the council before altering a stack in a conservation area or on a listed building
- Book a sweep for flues that are in use
Where another specialist is needed, such as a structural engineer or sweep, we explain why. It gives them a clear starting point.
Check your stacks from the street or garden after a storm. With binoculars, you can often see cracked flaunching or lifted lead.
Your questions about chimney surveys in Cannon Hill
Does a conservation area affect roof work in Cannon Hill?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Can a landlord with a rental near South Merton station book a roof survey?
Yes, landlords and agents book with us as well as owners. Just call 07833 053749 or use the contact form and let us know about the building, including who will give access on the day.
How many surveys have you done?
We’ve been surveying roofs for over 20 years and have completed over 5,000 surveys across London and South East England.
Will you walk on the roof?
Only if it is safe. We inspect what can safely be seen: from ground level, from windows and vantage points, from the roof space, from the roof itself where safe and by drone where applicable. Anything we can’t see is noted in the report.
Will you photograph what you find?
Yes. Photos are part of every report, so you can see each point for yourself.
Do you look in the roof space?
If the survey needs it and the loft space can be reached safely, yes. A clear path to the hatch helps.
What’s in the survey report?
It works through the roof part by part, in writing and with photos. Points are put by urgency where it matters.
