Roof leak investigation in Neasden
A leak that comes and goes can be the hardest to pin down. Driving rain from one direction, melting snow or a gutter that overflows in a downpour can all set it off. Telling us when it happens helps a lot, along with any photos you’ve taken. We look for the clues it leaves behind, like tide marks, stained timbers and damp underlay. Moisture detection shows which materials are still damp. We are often asked to look into damp walls below an overflowing gutter and water coming in around a roof light or dormer, on slate and tile slopes, valleys and parapet gutters and flat roof details.
Water getting into a London home often comes from a detail you can’t see from the street: the valley gutter in a butterfly roof, a parapet gutter, a chimney flashing or the flat roof over a rear extension. Whether you are tracing a leak or recording storm damage in Neasden, those are among the first places to look. A hidden gutter that overflows can send water a long way before it shows.
Findings are set out part by part, from the main slopes down to the gutters and outlets. You’ll see the good as well as the bad.

Wind, rain and roofs in Neasden
Fenton House, about 2.9 miles east, is one of the historic houses in the wider area around Neasden. 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 a listed home or one in a conservation area may need consent for changes of material. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Each of these roof types has its own typical places for water to get in.
If you look after a building like Northview Junior and Infant School, tracing a leak on a big roof starts with where the water appears and works back. For businesses in and around places such as London Designer Outlet, finding where water is getting in quickly keeps disruption down. Living close to Gladstone Park is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and an overflowing gutter soon means a wet wall.
Neasden is about 5 miles north-west of City of Westminster, in Greater London. We carry out roof leak investigations in Neasden for houses, flats, blocks and commercial buildings. Neasden is one of the towns and villages in Greater London where we work for roof leak investigations. We also survey roofs in London.

What else we do in Neasden
Different roofs, different checks
Valleys
A valley leak can appear well away from the valley inside. From inside the loft space, we follow the water’s route back.
Chimney stacks
Our chimney check is a visual inspection of the stack, not a flue, gas or sweep inspection.
Why get it checked now?
Wet insulation does not insulate well. Insulation can soak up water quietly before anything shows below. Catching it early limits what has to be replaced. Any roof job in Neasden means planning around parking, neighbours and access. That’s a good reason to find problems early, while there’s time to plan, rather than in a rush after a leak.
There are three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, all with VAT included. What your roof costs depends on its size, access and what you want to find out.
Why book us in Neasden
- Thermal imaging and drone inspection where they help
- Weekday and weekend surveys
- 5,000+ surveys completed
- Clear package prices, with VAT included
Landlord and commercial surveys in Neasden
Landlords and letting agents in Neasden book surveys as well as homeowners. The report gives you a dated record of the leaking roof, with photographs, useful for planning maintenance.
We also survey roofs for businesses and commercial landlords. Larger roofs take longer, so they’re priced to suit.
What affects the cost of roof leak investigations
A few things affect what a survey costs:
- How complicated the roof is, with its valleys, chimneys and parapets
- Which survey package you book
- The height of the building and how the roof can safely be seen
- Extra roofs, like extensions, dormers or garages
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. Our price is from £150, including VAT.
What we need to know
Here’s what helps us most when you get in touch:
- Pictures from the garden or a window, if you have them
- Your timetable, like an exchange date
- What kind of property and roof it is
- Your postcode, so we can check access and travel
Getting a price is simple: just phone 07833 053749 or email us and give us some details about the property and we’ll explain which survey suits. We confirm the price before anything is booked.
How the survey works
Before we start, tell us why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. It helps us focus on what matters most to you. The visit normally takes between one and 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 Neasden moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, let us know who can let us into the shared parts.
- We help you choose the package that suits the leak.
- We agree a date, including weekends.
- The investigation works from the stain back to the roof.
- Where it’s useful and included, we take moisture readings and use thermal imaging.
- You get photos, the likely cause and clear recommendations.
Before we arrive
- Keep pets inside or away from the areas we’re looking at
- Agree roof access with the managing agent if it is shared
- Jot down any questions you want answered
How to book

Related advice
What you can safely check yourself
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.
A lot can be seen from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
Common questions in Neasden
Is Neasden in the area you cover?
Yes. We survey roofs across London and South East England, and Neasden is part of that. Just phone 07833 053749 or email us and let us know about the property, and we’ll talk through which survey suits.
Is my home in Neasden listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Will you fly a drone over my roof?
Yes, where it applies and safe. We fly a sub-250g drone and we’re a CAA-registered drone operator (Flyer ID and Operator ID). Drone inspection is part of the Drone Roof Survey and the Premium Survey, where applicable.
Can you survey a shared roof?
Yes. Shared roofs just need a little more planning. Mention it when you get in touch and we will explain what’s needed.
What’s the best way to book?
It is easiest to phone 07833 053749 or send us an email. Tell us the address and a little about the roof, and we will take it from there. Surveys run on weekdays, Saturdays and Sundays.
Does the report include photographs?
Yes, every report has them. Each finding is shown in a picture where possible, which makes the report easy to follow.
Does the investigation include the repair?
Our job here is to trace the leak and explain it, and the repair is separate. The report gives any roofer a clear brief.
