Flat roof survey in Colliers Wood
Ponding is frequently the first sign that something on a flat roof is not right. It can point to poor falls, a blocked outlet or a deck that is deflecting. We record where water sits, check the outlets and look for dips that suggest deflection. If the deck itself looks like a structural concern, we’ll recommend a structural engineer. If you’ve noticed damaged trims at the roof edge and water getting in at rooflights, we can find out what’s behind it, whatever the roof.
Offices, shops and blocks of flats across London frequently have large flat roofs with plant, rooflights and walkways. Every penetration and upstand is a place where a membrane can fail. In Colliers Wood, roof access is agreed with the building manager or owner beforehand. Plant bases, rooflights and cable entries are all places where water can get in.
If any part of the flat roof couldn’t be seen safely, we say so in the report. You will know exactly what was inspected and what wasn’t, and what we’d suggest next.

Flat roof surveys in Colliers Wood: local notes
Historic houses like Southside House, about 2.8 miles west, show how far back building in the area around Colliers Wood goes. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material. Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops.
Take an older house close to St Nicholas: later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. For landlords with property near Tooting station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

Colliers Wood: your questions answered
Will parking be an issue for a roof survey in Colliers Wood?
It can be, so it helps to let us know about permits, visitor bays or off-street space when booking. The visit is then planned around what’s available.
Is my home in Colliers Wood listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
How much does a flat roof survey cost in Colliers Wood?
Prices start from £150, including VAT. You’ll know the exact price before booking, and it depends on the roof’s size, access and the package you choose. To get a price, ring 07833 053749 or use the contact form.
How quickly is the report sent?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline when you book.
Can you survey a shared roof?
Yes. A shared roof needs access agreed first. Tell us about it when booking and we will plan the survey around it.
Does the survey cover asbestos?
Our survey doesn’t include asbestos testing. Older buildings, from before 2000, may have asbestos in cement sheets or soffits. Anything that might contain it is flagged, so a specialist asbestos surveyor can check before work starts.
What if it rains on the day?
Some surveys depend on the weather more than others. Drone flights need calm, dry weather, and thermal imaging works best after a sunny day, with a dry roof and little wind. If the conditions are not right, we will talk to you about another date.
What happens if roof problems are left?
For a buyer, the best time to learn about a flat roof is before contracts are exchanged. After that, the cost of any work is yours. Our report gives you specific points to raise with the seller or agent. Blocked gutters and hoppers on London houses overflow and soak brickwork, which can lead to damp inside. A small blockage left for a few winters becomes a damp problem.
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.

How it works
We do not take risks to get a closer look. We inspect whatever is safely visible, and anything we cannot see is noted in the report. The survey usually takes an hour or two at a typical home, and more on a big or complicated roof. In a London area like Colliers Wood, 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. 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.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- Inside, we look for signs of water under the roof where we can reach.
- The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
- We record every defect with a photo and its likely cause.
- You get a report setting out the condition and our recommendations, in order of urgency.
Before we arrive
- If you are buying, check with the agent that we can get in
- Unlock side gates and any roof access doors
- Let us know where we can park nearby
Getting a price

When to book a survey in Colliers Wood
Water that doesn’t drain sits on the roof and speeds up wear. It normally comes from poor falls, a blocked outlet or a deck that has dipped. Where trees are close by, leaves and silt can block an outlet within a single autumn.
Most people get in touch when they’ve noticed one of these:
- Splits, cracks and crazing
- Raised blisters across the surface
- Damaged trims at the roof edge
- Outlets choked with leaves and silt
For a London address like Colliers Wood, it helps to know about controlled parking before the day, along with any off-street space.
