Roof leak investigations for homes and businesses in Streatham Hill
Some leaks only appear in certain weather. Wind-driven rain, an overflowing gutter or snow melt may be what triggers it. Notes on when it leaks, and what the weather was doing, help us and so do photos. We look for the clues it leaves behind, such as tide marks, stained timbers and damp underlay. Moisture readings show where materials are still wet. If you are worried about wet patches on loft insulation and water coming in around a roof light or dormer, we can find out what’s behind it, whatever the roof.
In a London flat, water can travel some way before it shows. Tracing it back matters, both for dealing with the cause and for any insurance claim. In Streatham Hill, 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.
The report is written in plain words, so you do not need to be a roofer to follow it. Each point is backed by a photo where possible.

DIY checks: what’s safe
Your own check is a good start, but it is not a survey. From ground level, valleys, flashings and the backs of chimneys are frequently out of sight.
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry.
Streatham Hill roofs and the weather
Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. Behind many of their parapets sit butterfly roofs and valley gutters that can’t be seen from the pavement. If your home in Streatham Hill is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Knowing the roof type helps narrow down where water may be getting in. About 1.9 miles east lies Kingswood House, a reminder of how long the area around Streatham Hill has been built on. Older homes in the wider area often have features worth a closer look, like 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 a London address like Streatham Hill, it is useful to know about controlled parking before the day. For businesses in and around places such as Southside Wandsworth, a quick answer on where water is coming in keeps a business running.

FAQs for Streatham Hill
Is parking a problem for a survey in Streatham Hill?
It can be, so it helps to tell us about permits, visitor bays or off-street space when booking. That way the visit can be planned around it.
Is Streatham Hill in the area you cover?
Yes, Streatham Hill is within the area we cover. We survey roofs across London and South East England. Just call 07833 053749 or use the contact form and let us know about the property, and we will talk through which survey suits.
What happens after the survey?
The report arrives by email. With Standard there is a follow-up consultation; with Premium, an in-person consultation, so you can talk the findings through.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and testing aren’t part of what we do. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings and suggest a specialist asbestos surveyor checks them before any work.
How fast do I get the report?
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.
Why is the stain in a different place from the leak?
Rain that gets in will run along whatever it lands on. On a pitched roof it often runs down a rafter before it shows. Tracing that path is the heart of a leak investigation.
How many surveys have you done?
We have more than 20 years’ experience and have carried out more than 5,000 surveys across London and the South East.
Tips from our surveys
Here are a few things we’d tell any owner:
- Note the weather when the leak shows
- Keep a photo record of the damp patch
- Catch drips in a bucket and protect the floor
- Mention any plumbing above the damp area
With the Standard Survey you get a follow-up consultation, and Premium includes an in-person consultation. You can ask us about anything that isn’t clear.
Plan a roof survey every few years. Flashings, valleys and flat roof details are frequent weak points, and wear is easier to deal with before water gets in.
What happens on the day
You do not need to do much on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll get on with the inspection. The survey itself takes roughly 1–2 hours for most houses; commercial roofs usually need 3–4 hours. In a London area like Streatham Hill, 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. We then look at everything that’s safely in view from the ground, windows, the loft and, where it’s safe, the roof itself.
- We start with your notes and photos of the leak.
- Inside, we look at the stain and the ceiling around it.
- In the loft, we follow any signs of water back towards the roof.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from each safe vantage point.
- We email a written report showing where the water most likely gets in.
Before the survey
- For a flat or shared roof, check access with the building owner or managing agent
- Have any questions written down, so nothing gets missed
- Find any records of previous roof work

Related advice
Why get it checked now?
A leak that returns after a repair usually means the real source wasn’t found. A careful investigation looks at every likely route, not just the obvious one. It gives the next repair a far better chance. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. When the stain finally shows, the damage underneath is often older than it looks.
Our price is from £150, including VAT. Basic starts from £150, Standard from £250 and Premium from £400, VAT included.

When to book a survey in Streatham Hill
A roof valley collects the rain from two slopes. Split linings, slipped valley tiles or debris can push water under the slates or tiles. Leaks from valleys often show up some distance away inside.
Things that often lead to a survey include:
- Damp patches next to the stack
- Leaks at a dormer or roof window
- Drips from nail tips in a cold loft
- Water dripping from rafters or underlay
Trees in and around Streatham Common shed leaves that can end up in nearby gutters.
Questions to ask before booking
- What’s outside the scope of the survey
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- Whether the inside of the roof is included
- What the report includes, and whether it has photographs
What we look for on each type of roof
Parapet and box gutters
A butterfly roof drains to a central valley gutter. If that gutter or its outlet fails, water can come through the top-floor ceiling.
Lead flashings
Lead flashings seal the joints at chimneys, walls and dormers. Lifted, split or slipped lead is a common cause.
