The survey, step by step
Safety comes first on every visit. Everything that can be seen safely is inspected, and if part of the roof cannot be seen, the report says so. The survey usually takes about one to two hours, more where the leak is intermittent or the roof is large. London terraces rarely offer a view of the whole roof from one spot, so a visit in Clapham moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Let us know who holds the keys.
- We start with your notes and photos of the leak.
- We examine the damp area and the rooms near it.
- From the roof space, we trace the water’s route where there is safe access.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from every safe vantage point.
- We email a written report showing where the water most likely gets in.
Preparing for the visit
- Check the loft hatch can be reached
- Jot down any questions you want answered
- Buyers: confirm access with the estate agent or seller

Advice
Roof leak investigation in Clapham: what you get
The aim is to find where the water is getting in and explain it. The report shows, with photos, where we believe the water gets in and how it travels, plus recommendations on what needs attention. Whoever does the work then has a clear starting point. We find and report the source, while the repair is a separate matter. We survey rooflights and dormers, slate and tile slopes and the roof space, and the problems we are asked to look at most are water dripping from rafters or underlay and staining around the chimney inside.
In a London flat, water can travel some way before it shows. That makes the source hard to pin down, and finding it matters for whoever has to deal with it. In Clapham, we inspect what we can reach safely and are given access to. It is useful to know when the water appears and in what weather.
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 applicable, structural analysis and an in-person consultation.

Useful tips for Clapham property owners
There is plenty you can do without going near the roof. What helps most:
- Record whether it leaks in every downpour or only some
- Mention earlier attempts to fix the leak
- Protect furniture and flooring under the leak
- Leave roof access to professionals
The report gives whoever carries out the work a clear starting point. The photos show the defects and where they are, rather than at the stain.
After a storm, check the roof from the garden and the street. Slipped slates, lifted ridge tiles and debris on the ground are signs to act on. Prompt repairs stop gaps turning into leaks.
Leaks and storm damage in Clapham
Carlyle's House, about 1.9 miles north-west, is one of the historic houses in the wider area around Clapham. 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. Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. Different coverings let water in at different points, which shapes where the search starts.
If you run a business near Harrods, finding where water is getting in quickly keeps disruption down. Anyone responsible for a site like Clapham Manor Primary School will know that tracing a leak on a big roof starts with where the water appears and works back. Living close to Larkhall Park is pleasant, but mature trees mean leaves in gutters and valleys each autumn.
Clapham is about 3 miles north of Streatham, in Greater London. Clapham is part of the area we cover and the surrounding area across London and South East England. Our area takes in places right across Greater London.

Your questions about roof leak investigations in Clapham
Will parking be an issue for a roof survey in Clapham?
Typically it is manageable with a little notice. Tell us what parking is available nearby, and the visit is planned around it.
How do I find out if my home in Clapham is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you’re planning to re-roof in a different material.
How long have you been surveying roofs?
Over 20 years and more than 5,000 surveys.
How long does the visit take?
On site, it typically takes an hour or two, more where the leak is intermittent or the roof is large. The report follows within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
Will you definitely find the leak?
Not always, and we will be honest about that. Some leaks hide well, especially those that need wind-driven rain. Where the source isn’t certain, we list the likely routes in order.
Do I have to be there for the survey?
Someone needs to let us in if we’re looking inside or in the loft. We will talk about access when you book.
Will you go up on the roof?
Only where it is safe to do so. We check everything that can safely be seen: from ground level, from windows, from inside the roof space, from the roof where it is safe and by drone where it applies. Anything we cannot see is noted in the report.
Why it is worth a survey now in Clapham
A leak rarely stays small. Damp spreads into rafters, ceilings and insulation. Tracing it now means less to put right later. In Clapham, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: failed flashings and blocked valley gutters can send water into more than one home. Finding it early keeps the work smaller.
Simple, low roofs take less time to survey than tall or complicated ones, and the package you pick makes a difference too. We’ll give you the figure before anything is booked.
