Roof surveys for homes and businesses in Belsize Park
Most houses have more than one roof to look at. Flat roofs over extensions, garages and dormers are common. We check them as well as the main pitched roof, including signs of standing water, splits and tired upstands. Flat roofs often need attention long before the main roof, so they deserve a proper look. A felt roof frequently lasts around 15 to 20 years, and GRP up to about 30. Typical surveys look at water stains on rafters and ceiling joists and ponding, splits or blisters on flat roofs, on natural slate, clay and concrete tiles and flat roofs.
London has Victorian and Edwardian terraces in almost every borough, many with Welsh slate roofs, shared chimney stacks and parapet or valley gutters. Slates can last a century or more, but the nails holding them corrode, and slates slip. In Belsize Park, as across London, that’s why a roof needs a careful look rather than a glance from the street. Shared chimney stacks and the lead around them are just as important to check.
Every survey ends with a written report, with photos, emailed to you. It sets out the condition of the roof, any defects and our written recommendations.

What a roof survey looks like in Belsize Park
Historic houses such as Keats House, about 0.8 miles north, show how far back building in the area around Belsize Park goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area. Inner London’s Victorian and Edwardian terraces frequently have Welsh slate roofs. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. On roofs like these, good slates or tiles can outlast the nails, battens, lead and mortar around them.
If you look after a shop, office or commercial unit, for example near O2 Centre, a written record of the roof’s condition helps you plan maintenance rather than react to leaks. If your home is one of the older ones in the streets near Church of St Mary the Virgin, the nails, lead and mortar on the roof may be wearing out even where the slates or tiles look fine.

What we are asked to look at in Belsize Park
What’s under the slates or tiles is as important as the coverings themselves. Breathable membranes only appeared in the UK in the late 1990s, so many older roofs have bitumen felt underlay, and some very old roofs have no underlay at all. Torn or sagging felt lets water through.
We’re often asked to look at:
- Torn or sagging underlay
- Valley linings that have cracked or split
- Cracked mortar along the ridge
- Lifted, split or missing lead flashings
If you let a flat or house near South Hampstead station, knowing the condition of the roof, chimneys and gutters helps you plan work rather than react to complaints.
What to check before booking
- Whether any drone flown is registered with the CAA
- How long they’ve been surveying roofs
- Will the report include photos?
- Which limits apply to the survey
What happens on the day
Photographs are taken throughout the visit, so you can see in the report what we found and where. We take close-ups from wherever is safe. Most surveys take roughly 1–2 hours for most houses, rising to roughly 3–4 hours on a commercial building. For a visit in Belsize Park, parking and access are the things to plan: 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 the ground, from windows, from inside the roof space and from the roof where it’s safe.
- We start with the property details and any concerns.
- A visit is booked for a weekday, Saturday or Sunday.
- Outside, we inspect from the ground, windows and other safe vantage points, and from the roof where safe.
- We then look in the loft for damp, staining and the condition of the underlay.
- You receive the report with photos and recommendations, prioritised by urgency.
Before we arrive
- Jot down any questions you want answered
- Find any records of previous roof work
- If you’re buying, let the agent know when we’re coming

Related advice
What happens if roof problems are left?
Planned work is less stressful than an emergency. A survey lets you deal with things in order of urgency, rather than waiting for something to fail. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. Knowing what’s needed early gives you time to plan it calmly, rather than in a rush after a leak.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Roof survey starts from £150, including VAT.

DIY checks: what’s safe
After strong wind, take a look from the pavement or garden: 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.
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.
Tips that help
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Do not climb onto the roof yourself
- Take photos of any leaks as they happen
- Have details of recent roof work to hand
- Ask about a flat roof on an extension or garage too
File the report with your other home documents. It is a useful baseline for future surveys, and it can help when you sell.
Keep the loft space ventilated. A stuffy loft collects condensation, which can dampen timbers and insulation over time. Check insulation does not block the airflow at the eaves.
Common questions in Belsize Park
Is drone flying allowed in Belsize Park?
Normally it comes down to two things: the airspace at the address and the weather. London’s airspace includes flight restriction zones around Heathrow, London City Airport and London Heliport, and restricted areas over Hyde Park, the City of London and the Isle of Dogs. Every London address is checked against them before a flight. Every flight is checked against the Drone Safety Map first. Strong wind or a downpour also stops a small drone flying.
Does a conservation area affect roof work in Belsize Park?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
What’s covered in a roof inspection?
All the main parts of the roof: coverings, ridges, valleys, flashings, chimneys, gutters and the loft. Standard adds moisture detection and a structural check, and Premium adds thermal imaging and a drone where applicable.
Does someone need to be in?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in; we’ll agree the details as you book.
Do you give a life expectancy for the roof?
We don’t put a figure on it, since the fixings, underlay and maintenance all play a part. Instead, we set out what’s sound, what’s wearing and what to do first.
How much does a roof survey cost in Belsize Park?
Our price is from £150, including VAT. Our three packages are Basic from £150, Standard from £250 and Premium from £400, with VAT included.
Do you look in the roof space?
If there’s a loft and safe access to it, yes. The loft space can show things the outside cannot, such as damp timbers, staining or daylight.
