What a roof leak investigation looks like in Walham Green
About 1 mile north-east lies Carlyle's House, a reminder of how long the area around Walham Green has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material. Many homes in inner London are Victorian and Edwardian terraces, often with Welsh slate roofs. Behind many of their parapets sit butterfly roofs and valley gutters that cannot be seen from the pavement. 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 Putney Exchange, a quick answer on where water is coming in keeps a business running. If you let a flat or house near Imperial Wharf station, tracing a leak quickly matters when a tenant is living with it.

How a roof leak investigation works in Walham Green
Older homes have more places for water to get in. Lead flashings crack or lift, valley linings wear and parapet gutters overflow when outlets block. A central valley gutter on a butterfly roof frequently turns out to be the source in heavy rain. Parapet walls and their gutters are checked from wherever it is safe. The findings are recorded with photos. Typical surveys look at damp ceilings under a flat roof and wet patches on loft insulation, across rooflights and dormers, valleys and parapet gutters and lead flashings.
In converted houses and blocks across London, water from a roof can run a long way before it shows on a ceiling. Tracing it back matters, both for dealing with the cause and for any insurance claim. In Walham Green, we inspect what we can reach safely and are given access to. Let us know when the water shows, and in what kind of weather.
We keep jargon out of it: if work is needed, the report says so clearly, along with how urgent it is.

What a roof leak investigation does not cover
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Whether rotten timbers meet design loads
- What’s under the covering or behind the plaster
- A promise to find every leak on a single visit
If in doubt, phone 07833 053749 or send us an email and we’ll suggest the right survey. What our survey covers.
Roofs we survey in Walham Green
- Valleys and parapet gutters
- Rooflights and dormers
- Lead flashings
- Chimney stacks
- Slate and tile slopes
- Flat roof details
- The roof space
The survey, step by step
On the day, we start by asking what you’ve noticed and what you want to find out. We then inspect everything that can safely be seen, using the ground, windows, the loft and a drone where it applies. Most surveys take about one to two hours on an ordinary house, though large, tall or awkward roofs take more time. London terraces rarely offer a view of the whole roof from one spot, so a visit in Walham Green moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Tell us 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’s safe access.
- 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
- Find any records of previous roof work
- Point out any leaks or damp patches
- Keep pets inside or away from the areas we are looking at

When to book a survey in Walham Green
A roof valley collects the rain from two slopes. Worn lead, cracked linings or a build-up of leaves and moss can push water under the slates or tiles. The stain may appear well away from the valley itself.
Signs worth acting on include:
- Damp ceilings under a flat roof
- Staining around the chimney inside
- Brown rings on upstairs ceilings
- Leaks that appear only in driving rain
For site and facilities teams at buildings such as Chelsea Independent College, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.
Questions to ask before booking
- How much experience they have with roofs like yours
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Are they insured for the work?
- When you will get the report
Before and after the survey
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Let us know what has already been tried
- Take dated photos of the leak
- Keep water away from lights and sockets
- Let us know if there are tanks or pipes in the loft
If the leak turns out to be condensation, the report says so, with recommendations on ventilation. It saves chasing a leak that is not there.
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.

London parking needs a little planning, so let us know about permits, bays or a driveway as you book. That way the visit can be planned around it.
Does someone need to be in?
Not always. If we only need the outside, we can agree that beforehand, but the loft and any rooms with damp need someone to let us in.

We survey seven days a week: Monday to Friday, Saturdays and Sundays. Let us know which days suit you when booking.
