Roof leak investigations for homes and businesses in Little Venice
We use moisture detection and thermal imaging where they help. Moisture readings show which materials are wet. Thermal imaging shows temperature differences that can point to wet areas, not water itself, so its findings are checked with moisture readings. Moisture detection is included in the Standard Survey, and thermal imaging in Premium. Thermal imaging works best after a sunny day, on a dry roof with little wind. Typical surveys look at wet patches high on an inside wall and drips in the loft during heavy rain, on lead flashings, chimney stacks and slate and tile slopes.
In London, leaks frequently start somewhere hidden: the valley gutter in a butterfly roof, a parapet gutter, a chimney flashing or the flat roof over a rear extension. For a leak or storm damage in Little Venice, those hidden details are where the inspection begins. A hidden gutter that overflows can send water a long way before it shows.
The report records the leaking roof as we found it on the day. That makes it useful now and a handy reference later, such as when you want to compare after future work.

FAQs for Little Venice
Will parking be an issue for a roof survey in Little Venice?
London parking needs a little planning, so let us know about permits, bays or a driveway as you book. The visit is then planned around what’s available.
Is Little Venice in the area you cover?
Yes, Little Venice is within the area we cover. Our area covers London and the South East. You can phone 07833 053749 or use the contact form with the address and some details.
Is thermal imaging part of a leak investigation?
It can, when the conditions are right. The best results come after a sunny day, on a dry roof with little wind. Damp areas can hold heat differently from dry ones. Its findings are confirmed with a moisture check.
Is it a structural engineer’s report?
No. We point out what can be seen, such as sagging or deflection, but we’re not structural engineers and don’t carry out calculations. Where an engineer is needed, we say so in the report.
How do I arrange a roof leak investigation in Little Venice?
Simply phone 07833 053749 or send us an email. We will ask a few questions, confirm the price and agree a date, weekday or weekend.
Do you look in the roof space?
Normally, if there is one and it can be reached safely. From inside, the underside of the roof frequently shows damp, staining or daylight that can’t be seen from outside.
Can you always find the source?
We cannot promise it. Some leaks hide well, especially those that need wind-driven rain. Where the source is not certain, we list the likely routes in order.
Practical tips
A survey works best with a little help from you, before and after. Some tips:
- Don’t touch fittings that water is reaching
- Leave roof access to professionals
- Photograph the stain each time it appears
- Put a bucket under the drip and move valuables
Your report arrives by email, with photographs of what we found. It sets out where we believe the water is getting in, how it’s travelling and what needs attention. Basic reports come within 48 hours, Standard within 24 to 48 hours and Premium the same day.
Keep gutters, valleys and outlets clear, ideally once the leaves have fallen. Blocked outlets on parapet and flat roofs cause many leaks. Leave the clearing to someone with the right equipment.
What we do, step by step
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes roughly 1–2 hours for most houses, or half a day or so for a commercial building. If you have questions on the day, just ask. In a London area like Little Venice, the main things to sort out are parking and access: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. On the day, the roof is looked at from ground level, from windows, from inside the loft space and from the roof where it’s safe.
- You get in touch with details of the leak and any photos.
- Inside, we check the damp area and the roof space above it.
- Likely entry points outside are looked at, from flashings and valleys to gutters and outlets.
- Moisture readings and thermal imaging are used where they help.
- Your report sets out where the water is most likely getting in, with photos and recommendations.
Preparing for the visit
- Mention any parking restrictions on your street
- Find any records of previous roof work
- Buyers: confirm access with the estate agent or seller

What we look for on each type of roof
Flat roof upstands and outlets
Flat roof water can travel under the covering before it shows. Where conditions allow, moisture readings and thermal imaging help narrow it down.
Slate and tile slopes
Ridge and hip tiles can loosen as their mortar cracks. Rain can then run in at the ridge.
Do you need a roof leak investigation in Little Venice?
Flashings are one of the commonest sources of roof leaks. Where a roof meets a chimney, a wall or a dormer, lead or mortar seals the joint. When lead lifts or splits, or a mortar fillet cracks, rain runs straight in.
It’s worth booking a survey if you’ve seen:
- Water that shows only in certain storms
- Damp patches next to the stack
- Damp walls below an overflowing gutter
- Ceiling stains that grow after rain
Anyone responsible for a site like Ark Paddington Green Primary Academy will know that water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.
Questions to ask before you book
- How long they’ve been surveying roofs
- Whether the loft is part of the inspection
- Whether VAT is added on top
- What exactly goes into their report
Roof leak investigations around Little Venice
Many homes in inner London are Victorian and Edwardian terraces, frequently with Welsh slate roofs. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. If your home in Little Venice is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Each of these roof types has its own typical places for water to get in. The wider area around Little Venice has a long history of building, with Winfield House about 1 mile north-east. Older homes in the wider area frequently have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.
If you own a rental within reach of London Paddington station, tracing a leak quickly matters when a tenant is living with it. If you live in an older home near St Saviour's Church, leaks on older roofs frequently start at lead flashings, valleys or around old chimney stacks.
