Roof leak investigation in Gillette Corner, Greater London
Wondering about the leaking roof at a property in Gillette Corner? You can book a roof leak investigation in Gillette Corner and across Greater London, with plain-English findings.
- Water dripping from rafters or underlay
- Stains around a skylight
- Water through the ceiling under a flat roof
Different roofs, different checks
Parapet and box gutters
Hidden gutters run behind parapets or between roofs. When their outlets block, water rises over the lining and runs indoors.
Flat roof upstands and outlets
Outlets drain a flat roof. When one blocks, water ponds and finds any weak spot. Outlets and the area around them are checked.
How a roof leak investigation works in Gillette Corner
Flat roofs leak in their own ways. Common causes are splits and blisters, tired upstands and outlets that do not drain. Ponding water makes any weakness worse. We check both the covering and the room underneath. Flat roofs over extensions, garages and dormers are frequent sources of leaks. Felt frequently lasts around 15 to 20 years, so age is part of the picture. We survey chimney stacks, the roof space and valleys and parapet gutters, and people most frequently book us about brown rings on upstairs ceilings and damp ceilings under a flat roof.
In converted houses and blocks across London, water from a roof can run a long way before it shows on a ceiling, sometimes in a different flat from the one below the defect. Tracing it back matters, both for dealing with the cause and for any insurance claim. We check what we’re given access to in Gillette Corner, inside and out. It is useful to know when the water appears and in what weather.
The report records the leaking roof as we found it on the day. It’s useful right away, and a good reference for later, such as when you want to compare after future work.

What happens on the day
On the day, we start by asking what you’ve noticed and what you’d like to know. After that, we check everything we can see safely. The survey typically takes about 1–2 hours for most houses, or half a day or so for a commercial building. London terraces rarely offer a view of the whole roof from one spot, so a visit in Gillette Corner moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, tell us who can let us into the shared parts.
- You let us know where the water shows and when it appears.
- The visit starts indoors, at the stain and in the loft.
- Outside, we look at every likely route in.
- Where it helps, we take moisture readings and use thermal imaging.
- Your report sets out where the water is most likely getting in, with photos and recommendations.
Before the survey
- For flats, make sure roof access has been agreed
- Check pets are kept safely away
- Gather any invoices or paperwork from past roof work

What a roof leak investigation looks like in Gillette Corner
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. The covering and its details give the first clues when tracing where water is coming from. About 0.7 miles north-east lies Boston Manor, a reminder of how long the area around Gillette Corner has been built on. If your house is among the older ones, expect a mix of original materials and later repairs on the roof.
Landlords with a home close to Syon Lane station may find that finding the cause of a leak fast keeps a tenant’s home dry and the work focused. Take a building like Marlborough Primary School: water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot. If you live in an older home near St Mary's Church, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks.

What happens if roof problems are left?
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. Blocked gutters and hoppers on London houses overflow and soak brickwork. A blocked outlet ignored for a winter or two can mean damp walls inside.

Questions from Gillette Corner
Is parking a problem for a survey in Gillette Corner?
It depends on the street. If Gillette Corner has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
How do I find out if my home in Gillette Corner is listed?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
How much does a roof leak investigation cost in Gillette Corner?
Our price is from £150, including VAT. We confirm the price for the job before booking, and it depends on the roof’s size, access and the package you choose. To get a price, phone 07833 053749 or use the contact form.
Will you check the loft?
If it is needed and safe to reach, yes. We look for staining, damp, daylight and signs of movement.
Do you test for asbestos?
No. Our report may flag materials that could contain asbestos, but confirming it is a job for a specialist asbestos surveyor. Buildings built or refurbished before 2000 may contain it.
Will you walk on the roof?
Not unless it’s safe. Most of what we need can be seen from safe viewpoints, the loft and, where applicable, a drone, and the report notes anything we couldn’t see.
What’s the best way to book?
Just call 07833 053749 or email us with the address. After a few questions, we confirm the price and fix a day, weekday or weekend.
Should I look at the roof myself first?
During heavy rain, look at the gutters from the ground or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
Honest limits
Our survey isn’t a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Putting the leak right
- Water from pipes, tanks or heating systems
- What’s under the covering or behind the plaster
