What a roof leak investigation does not cover
This is not a RICS building survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Water from pipes, tanks or heating systems
- Structural calculations (that is a structural engineer’s job)
- Leaks that only appear in weather we cannot recreate

How a roof leak investigation works in Turnham Green
Not every drip is a leak. Condensation in a cold, poorly ventilated loft can drip from nails and timbers, leaving marks that look just like rainwater. Knowing which it is means the right fix can be done, because they need very different work. The pattern of the damp, the ventilation and the timing all help us decide. We survey the roof space, lead flashings and slate and tile slopes, and people most often book us about leaks below a flat extension roof and water marks that spread in wet weather.
London’s Victorian and Edwardian roofs have frequently been repaired many times. Telling wear from a one-off event matters, because insurers usually exclude wear and tear. That is as true in Turnham Green as anywhere in London. Photos and a written account give you something specific to show an insurer, a landlord or a roofer.
The report is written in plain words, so you don’t need to be a roofer to follow it. Photos show what each point refers to, with the urgent items made clear.

What affects the price in Turnham Green
Several things affect the price of a survey:
- Any need for thermal images or a drone flight
- Building height and the viewpoints available
- Whether you choose the Basic, Standard or Premium Survey
- Whether it’s a home or a commercial building
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package matters as well. The price is always agreed first.
What we need to know
To price your survey accurately, we will ask about:
- When you need the report by
- Access details, such as a loft hatch or a shared roof
- Where any leaks, stains or damp patches show inside
- Pictures from the garden or a window, if you have them
Roof leak investigation starts from £150, including VAT. The exact figure depends on the roof and the package, so phone 07833 053749 or use the contact form with the details.
Roof leak investigations around Turnham Green
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Different coverings let water in at different points, which shapes where the search starts. About 0.2 miles west lies Hogarth's House, a reminder of how long the area around Turnham 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.
Homes near green spaces such as Dukes Meadows can get more leaves in their gutters in autumn, and an overflowing gutter soon means a wet wall. If you live in an older home near St. Nicholas Church, old mortar, worn lead and slipped slates are the usual suspects when water gets in.

What happens on the day
We photograph the roof as we go, so the report shows exactly what we saw. We take close-ups from wherever is safe, including by drone where it’s applicable and the weather allows. A typical visit takes roughly 1–2 hours on an ordinary house; commercial roofs usually need 3–4 hours. For a visit in Turnham Green, 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.
- We start with your notes and photos of the leak.
- Inside, we check 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 every safe viewpoint.
- You receive a report with the likely source, photos and recommendations.
Before the survey
- Tell us where we can park nearby
- Keep pets in another room
- Buyers: confirm access with the estate agent or seller

Common questions in Turnham Green
Will parking be an issue for a roof survey in Turnham Green?
It can be, so it’s useful to tell us about permits, visitor bays or off-street space when booking. The visit is then planned around what’s available.
Is my home in Turnham Green listed or in a conservation area?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
Do you need to get into the loft?
Where it is relevant to the survey and there is safe access, yes. Please clear anything stored under the hatch.
How much is a survey?
Prices start from £150, including VAT. The final figure depends on the roof and the package you choose, confirmed before anything is booked.
Can you trace a leak in dry weather?
In most cases, yes. Damp materials can be found without rain. For leaks that only happen in certain storms, we report the most likely routes.
How many surveys have you done?
Over 5,000 surveys so far, across 20+ years of surveying roofs, and 98% of clients are satisfied.
Does someone need to be in?
It depends on what we need to see. For inside areas and the loft space, someone has to give us access; we will agree the details when booking.

What we’re asked to look at in Turnham Green
Every flat roof covering has a working life. Felt often lasts around 15 to 20 years, and as it ages it splits, blisters and opens at the laps. Upstands and outlets are common weak points.
Things that often lead to a survey include:
- Staining where a gutter or parapet meets the wall
- Damp on a chimney breast
- Brown rings on upstairs ceilings
- Damp ceilings under a flat roof
If you let a flat or house near Chiswick station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused.
Questions to ask before you book
- Whether the loft is part of the inspection
- Their report turnaround times
- Whether VAT is added on top
- Is there a chance to talk the report through?
Different roofs, different checks
Slate and tile slopes
A gap in the coverings exposes the underlay. Older felt may hold for a while, but it tears with age.
Chimney stacks
A stack has several possible ways in for rain. Each is looked at from every safe viewpoint, and look for damp on the breast inside.
Why act early in Turnham Green
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. Many older London roofs have only old felt under the slates, or no underlay at all, so a slipped slate can soon mean water inside. Left alone, that means wet timbers and plaster, which is a far bigger job than the roof fault itself.
Price depends partly on the package: Basic from £150, Standard from £250 or Premium from £400, all including VAT. Size, height and access can affect the price too.
