About our flat roof survey in Clapham Junction
Ponding is frequently the first sign that something on a flat roof is not right. It can mean the falls were never right, an outlet is blocked or the deck has started to sag. The survey notes any ponding, the state of each outlet and any dips that hint at a sagging deck. Where the deck may be a structural issue, our report says a structural engineer should look at it. If you’ve noticed outlets choked with leaves and silt and water getting in at rooflights, a survey will tell you what’s going on.
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 Clapham Junction, 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.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

The survey, step by step
Photographs are taken throughout the visit, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available. A typical visit takes about one to two hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. For a visit in Clapham Junction, parking and access are the things to plan: let us know about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at what can safely be seen from the ground, windows, the loft and, where it’s safe, the roof itself.
- 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.
- Each defect is photographed and its likely cause noted.
- You get a report setting out the condition and our recommendations, in order of urgency.
Preparing for the visit
- Mention any parking restrictions on your street
- Make sure we can get to the back of the property
- Gather any invoices or paperwork from past roof work

What else we do in Clapham Junction
Tips that help
You don’t need to be a roofer to help. What helps most:
- Ask whoever fits equipment on the roof to make good the covering
- Look for standing water a day after rain
- Clear roof outlets and gutters each autumn
- Have the roof looked at again after a severe storm
The report is emailed to you, ready to share with a roofer, the seller or a managing agent. Each defect is described in plain words and shown in a photo, so anyone reading it can see what we saw.
Small defects are simpler to deal with while they’re still small. A flat roof that is looked after between surveys normally lasts longer.
Signs you need a flat roof survey in Clapham Junction
No flat roof covering lasts for ever. Around 15 to 20 years is common for felt, while EPDM often lasts 30 to 50 years and GRP up to about 30, though workmanship and upkeep make a big difference. A survey shows how yours is holding up, whatever its age.
Signs worth acting on include:
- Splits and cracks in the covering
- Damaged trims at the roof edge
- Outlets that hold water back
- Water getting in at rooflights
Take a building like Christ Church CofE Primary School: schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.
Questions to ask before booking
- Are they insured for the work?
- Which limits apply to the survey
- Whether VAT is added on top
- Whether the loft space is looked at, where there is one
Clapham Junction questions
Does a conservation area affect roof work in Clapham Junction?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Can you look at the flat roof of a hotel or office near Clapham Junction?
Yes. As well as homes, we check flat roofs on offices, hotels, blocks of flats and commercial units. For a bigger roof, you will get a quote based on the building, and roof access is agreed with you ahead of the visit.
How soon will I get the report?
It depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. The report is emailed to you.
Will you go up on the roof?
Only where it’s safe to do so. We check everything that can safely be seen: from the ground, from windows, from inside the roof space, from the roof where it’s safe and by drone where it applies. The report says if anything couldn’t be seen.
What does the report include?
Written findings with photographs, covering the condition of the flat roof, the defects we found and what we recommend. The Standard Survey adds moisture detection and a structural check, and the Premium Survey adds thermal imaging, drone inspection where applicable and structural analysis.

Local flat roofs in Clapham Junction
Inner London’s Victorian and Edwardian terraces frequently have Welsh slate roofs. 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. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. With Carlyle's House about 1.4 miles north, Clapham Junction sits in an area with a long building history. 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 any change of roofing material on a listed home needs checking with the council first.
For landlords with property near Clapham Junction station, the flat roof over a let home is worth a look before it becomes a tenant complaint. Shop and office owners around Southside Wandsworth may find that flat roofs over shops and units are easy to forget until water comes through a ceiling.
