How a roof leak investigation works in Brentford
Our job is to find the likely source and tell you. The report shows, with photos, where we believe the water gets in and how it travels, plus recommendations on what needs attention. Whoever does the work then has a clear starting point. We find and report the source, and the repair itself is a separate job. If you’ve noticed leaks that appear only in driving rain and water coming in around a roof light or dormer, a survey will tell you what’s going on.
Many London homes are well over a century old and their roofs have been patched more than once, so a new leak can be the latest sign of wear rather than a single event. Insurers usually exclude wear and tear, so it helps to know whether damage is old or new. A careful look in Brentford tells the two apart where the evidence allows. A written record with photos helps you explain what was found to whoever deals with it next.
Report times depend on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

Common questions in Brentford
Can parking be tricky for a visit in Brentford?
Sometimes, yes. If Brentford has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
Is my home in Brentford 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 carry professional indemnity insurance?
We hold professional indemnity and public liability insurance, for every survey we carry out.
Can you survey at the weekend?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Let us know your preferred days when you book.
Do I have to be there for the survey?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in, while outside access can be discussed when booking.
Can you inspect my roof with a drone?
Yes, where it’s applicable. Flights depend on the weather on the day and airspace rules, and we check for restrictions near airports before flying. We hold a CAA Flyer ID and Operator ID.
Will I get photos?
Yes. Photographs are taken throughout the survey, and the report uses them to show each finding alongside our recommendations.

What else we do in Brentford
Roof leak investigations around Brentford
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Knowing the roof type helps narrow down where water may be getting in. The wider area around Brentford has a long history of building, with Kew Palace about 0.5 miles south-east. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
If you look after a building such as St Paul's CofE Primary School, a leak through a large roof is often found some distance from where the water shows inside. For businesses in and around places such as Treaty Centre, a leak can close part of a shop or office, so finding the cause quickly matters.
Brentford is about 2 miles south of Ealing, in Greater London. If you are in Brentford, booking works exactly as it does anywhere else: a call or an email, a price, then a date. Brentford is one of the places in Greater London we cover for roof leak investigations. London is in our area too.

A little further out are Treaty Centre (3 miles south-west) and Musical Museum (0.5 miles east). Not far away are Kew Gardens Lake and Long Wood.
What we look for on each type of roof
Valleys
A valley takes the rain from both sides of the roof. Split lead, cracked linings or slipped tiles let water in.
Slate and tile slopes
Cracked mortar lets ridge and hip tiles move. Rain can then run in at the ridge.
Signs you need a roof leak investigation in Brentford
A chimney stack has lots of places for rain to get in. Eroded pointing, cracked flaunching, failed flashings and open pots can all be responsible. It can show up on the chimney breast, nearby ceilings or in the roof space.
It’s worth booking a survey if you’ve seen:
- Leaks at a dormer or roof window
- Damp underlay across a wide area
- A leak that comes and goes with the weather
- Drips in the loft during heavy rain
For an older house near a landmark such as Congregational Church, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks.
What to check before booking
- Are they insured for the work?
- What’s outside the scope of the survey
- Whether you get a written report with photos
- Whether the loft is part of the inspection
What you can safely check yourself
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can point to a blockage or a sagging run.
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry, as it helps us focus the survey.
Practical tips
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Leave roof access to professionals
- Move stored items away from the hatch
- Note the weather when the leak shows
- Take dated photos of the leak
If condensation is the cause, we explain it, and suggest how the loft space could be better ventilated. That avoids roof work that wouldn’t help.
Look at the roof from ground level after strong winds. Slipped slates, lifted ridge tiles and debris on the ground are signs to act on. Prompt repairs stop gaps turning into leaks.
The survey, step by step
After the inspection, everything we found is written up as a written report with photos, sent to you by email. As for time on site, most surveys take roughly 1–2 hours, more where the leak is intermittent or the roof is large. Many London properties are flats or terraces with no side access, so the back of the roof is frequently seen from upstairs windows, from inside or, where a flight is allowed, from the air. If the building has a managing agent or access rules, let us know as you book.
- 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 every safe viewpoint.
- You receive a report with the likely source, photos and recommendations.
Before the survey
- Keep pets in another room
- Have any paperwork from past roof work to hand
- Jot down any questions you want answered
