Roof leak investigation in Paddington: what you get
Leaks tend to begin where one part of a roof meets another. Flashings at chimneys and walls, valleys, gutters, parapets and flat roof upstands and outlets are the usual suspects. We check each likely route and we follow where the evidence leads. Every chimney, dormer and roof light adds more joints to check. We check all of them, from every safe viewpoint. If you’ve noticed stains around a skylight and water dripping from rafters or underlay, we can find out what’s behind it.
Water getting into a London home frequently 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. For a leak or storm damage in Paddington, those hidden details are where the inspection begins. A hidden gutter that overflows can send water a long way before it shows.
After the visit, you get a written report with photos, emailed to you. It sets out the condition of the leaking roof, any defects and our written recommendations.

Do you need a roof leak investigation in Paddington?
Every flat roof covering has a working life. Felt often lasts around 15 to 20 years, and as it ages it splits, blisters and opens at the laps. Upstands and outlets are common weak points.
It is worth booking a survey if you’ve seen:
- Water through the ceiling under a flat roof
- Staining around the chimney inside
- A leak that comes and goes with the weather
- Ceiling stains that grow after rain
If you look after a building like International Community School, tracing a leak on a big roof starts with where the water appears and works back.
Questions to ask before booking
- What follow-up you get after the report
- Whether the roof space is looked at, where there is one
- What the survey won’t cover
- When you’ll get the report
Your questions about roof leak investigations in Paddington
Does a conservation area affect roof work in Paddington?
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.
Do you carry out roof surveys in Paddington?
Yes. Our area covers London and South East England, and Paddington is part of that. You can ring 07833 053749 or use the contact form with the address and some details, and we’ll talk through which survey suits.
What’s in the report?
It works through the roof part by part, in writing and with photos, and ends with what we recommend. The most urgent items are made clear.
Can every leak be traced?
Not always, and we’ll be honest about that. Water can travel a long way, and some leaks only show in particular storms. If we can’t be sure, the report ranks the possible sources.
Is this an asbestos survey?
No. Asbestos surveys and sampling are not something we do. Where a material might contain it, like old cement sheets on a building from before 2000, the report flags it.
Do you use thermal imaging to find leaks?
It can, when the conditions are right. It works best after a sunny day, with a dry roof surface and little wind. Damp areas can hold heat differently from dry ones. Its findings are confirmed with a moisture check.
How do I book a survey in Paddington?
It’s easiest to ring 07833 053749 or drop us an email. Give us the address and some details about the roof. Surveys run on weekdays and at weekends.
Tips that help
Over many surveys, some simple habits stand out as worth the effort:
- Take dated photos of the leak
- Tell us about any past repairs to the roof
- Clear the loft hatch so we can get in
- Don’t touch fittings that water is reaching
Keep the report after the work is done. If water appears again, it shows what was found before.
Have leaves and moss cleared from gutters, valleys and outlets, ideally once the leaves have fallen. Blocked outlets on parapet and flat roofs cause many leaks. Use a professional rather than climbing up yourself.
What we look for on each type of roof
Lead flashings
Mortar fillets are sometimes used instead of lead. Fillets crack and pull away over time, and water runs down behind them.
Chimney stacks
Damp on a chimney breast inside often starts at the top of the stack. Open, unused pots let rain fall down the flue.

What else we do in Paddington
What a roof leak investigation does not cover
We only report whatever is safely visible on the day, so some things are outside what a survey can do:
- An intermittent leak that shows no trace on the day
- Whether rotten timbers meet design loads
- Defects hidden under coverings or inside walls without opening up
If in doubt, call 07833 053749 or drop us an email and we’ll suggest the right survey. The full list of what we check.

The survey, step by step
Every roof is different; as a rough guide, the survey takes between one and two hours for most houses, rising to roughly 3–4 hours on a commercial building. If you have questions on the day, just ask. Surveys in Paddington can be booked for any day of the week. London parking is frequently by permit or pay-and-display, so it’s useful to know what’s near you. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- We start with your notes and photos of the leak.
- 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.
- We email a written report showing where the water most likely gets in.
Getting ready for the survey
- Make sure we can get to the back of the property
- Dig out any old roof reports or invoices
- If you’re buying, check with the agent that we can get in
How to book
Not sure which survey you need? It is easiest to ring 07833 053749 or email us and describe the roof and why you want it surveyed. We will explain the options and the price.

Roof leak investigations around Paddington
About 1 mile north lies Winfield House, a reminder of how long the area around Paddington has been built on. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area. Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. Behind many of their parapets sit butterfly roofs and valley gutters that cannot be seen from the pavement. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Where water gets in depends a good deal on what the roof is made of and how it’s detailed.
Take an older house close to Church of St John the Evangelist: the leak may come from a chimney, a valley or tired lead rather than the covering itself. If you look after a shop, office or commercial unit, for instance near Harrods, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.
