Southall Roof Leak Investigation
Roof leak investigations in Southall, backed by more than 20 years’ experience. You get a clear report with photos.
- Damp walls below an overflowing gutter
- Leaks below a flat extension roof
- Damp underlay across a wide area
Honest limits
Some things cannot be seen without opening up the roof, and that sets some limits:
- Structural calculations (that is a structural engineer’s job)
- The repair itself (the investigation finds and reports the cause)
- Plumbing leaks that look like roof leaks

How a roof leak investigation works in Southall
Most roof leaks start at a joint rather than the middle of a slope. Common entry points include chimney and wall flashings, valleys, parapet and box gutters, and the upstands and outlets on flat roofs. We check each likely route and follow the evidence. Every chimney, dormer and roof light adds more joints to check. We check all of them, from each safe vantage point. We’re frequently asked to look into water dripping from rafters or underlay and water coming in around a roof light or dormer, across slate and tile slopes, lead flashings and flat roof details.
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’s useful to know whether damage is old or new. A careful look in Southall tells the two apart where the evidence allows. Photographs and a written account give you something specific to show an insurer, a landlord or a roofer.
The report records the leaking roof as we found it on the day. That makes it useful now and a handy reference later, for instance when you want to check whether anything has changed.

What else we do in Southall
Surveys for landlords and agents in Southall
If you own several properties, surveys can be booked for more than one address. To arrange surveys for several addresses, call 07833 053749 or drop us an email.
Letting agents frequently book on a landlord’s behalf, and the report can go to both. Access is agreed with the tenant beforehand.
What we do, step by step
Once we have finished looking, we write up our findings as a photo-illustrated written report, emailed to you. On timing, most surveys take about 1–2 hours on an ordinary house, and more on a big or complicated roof. In Southall, as in much of London, lots of properties are flats or terraces without side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. Mention any building rules, key holders or managing agents as you book.
- You tell us where the water appears, when, and what the weather was doing.
- We examine the damp area and the rooms near it.
- In the loft, we follow any signs of water back towards the roof.
- We inspect the likely entry points outside, from the ground, windows and the roof where safe.
- You receive a report with the likely source, photos and recommendations.
Before we arrive
- Point out any leaks or damp patches
- If you are buying, check with the agent that we can get in
- For a flat or shared roof, check access with whoever owns or manages the building
Booking a survey
Getting a price is simple: just call 07833 053749 or use the contact form and give us a few details about the property and we will explain which survey suits. We confirm the price before anything is booked.
Advice
What we look for on each type of roof
Lead flashings
Lead flashings seal the joints at chimneys, walls and dormers. We check for lead that has lifted, split or slipped.
Chimney stacks
Water that gets in at the top can show up lower down. Open, unused pots let rain fall down the flue.
Roof leak investigations around Southall
With Osterley House about 1.7 miles south-east, Southall sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. If your home in Southall is one of them, bay roofs, hips and later dormers each have their own details. Each of these roof types has its own typical places for water to get in.
If you look after a shop, office or commercial unit, for instance near Treaty Centre, a leak can close part of a shop or office, so finding the cause quickly matters. If you look after a building like Hambrough Primary School, on a building that size, finding the source of a drip means looking well beyond the stain. The streets around a church such as Saint John are often among the oldest in a place, and if your home is one of the older ones nearby, water on an older roof tends to find its way in at the lead, the valleys or the chimney.
Southall is about 3 miles west of Ealing, in Greater London. Southall gets the same service as everywhere else we work: a careful inspection, photos and a written report. Southall is one of the places in Greater London where we work for roof leak investigations. There’s also a page for London.

FAQs for Southall
How do I find out if my home in Southall is listed?
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.
Is parking a problem for a survey in Southall?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Do you test for asbestos?
No. We can flag materials that might contain asbestos, but only a specialist asbestos surveyor can confirm it. Buildings built or refurbished before 2000 may contain it.
What happens after the survey?
The report comes by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
Do you work in Southall?
Yes. We survey roofs across London and South East England, Southall included.
Can you survey at the weekend?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Just tell us the days that suit you.
Are you structural engineers?
No. We’re experienced roof surveyors, and visible signs like sagging are noted, but we do not provide calculations or an engineer’s opinion. The report will say if you need an engineer.
Can I check my roof myself?
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
A DIY look is useful, but it is not a survey. From ground level, valleys, flashings and the backs of chimneys are frequently out of sight, and those are details a survey looks at closely.
What affects the cost of roof leak investigations
To price your survey, we check:
- Roof area
- Commercial roofs and larger buildings
- Basic, Standard or Premium
- Whether thermal imaging or a drone is needed
Every price we give includes VAT. Our price is from £150, including VAT. We confirm the price for your survey before booking.
What we need to know
When you call or email, these details help:
- Your postcode, so we can check access and travel
- Where water is showing inside, if it is
- Photos of the roof, taken safely from ground level or a window
- Dates you are working to, such as exchange
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. For any other survey, just call 07833 053749 or use the contact form when you are ready.
