How a roof leak investigation works in Seven Dials
Not every drip is a leak. Condensation in a cold, poorly ventilated loft can drip from nails and timbers, and the stains look much like a leak. Telling the two apart matters, because they need very different work. We check the pattern of damp, the weather and the ventilation before reaching a view. We survey slate and tile slopes, valleys and parapet gutters and lead flashings, and common reasons people get in touch are damp underlay across a wide area and ceiling stains that grow after rain.
Many London homes are well over a century old and their roofs have been patched more than once. Telling wear from a one-off event matters, because insurers typically exclude wear and tear. A careful look in Seven Dials tells the two apart where the evidence allows. Photos and a written account give you something specific to show an insurer, a landlord or a roofer.
Every survey ends with a written report, with photographs, emailed to you. It explains the condition of the leaking roof, the defects we found and what we recommend.

Tips from our surveys
There’s plenty you can do without going near the roof. Here’s what helps most:
- Protect furniture and flooring under the leak
- Photograph the stain each time it appears
- Move stored items away from the hatch
- Do not touch fittings that water is reaching
Your report arrives by email. It sets out where we believe the water is getting in, how it is travelling and what needs attention. Basic reports come within 48 hours, Standard within 24 to 48 hours and Premium the same day.
Check the loft after heavy rain, with care and a good torch. Look for drips, damp patches and stains on timbers. Photograph anything new.

Wind, rain and roofs in Seven Dials
Benjamin Franklin House, about 0.4 miles south, is one of the historic houses in the wider area around Seven Dials. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first. Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. If your home in Seven Dials is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Different coverings let water in at different points, which shapes where the search starts.
Shop and office owners around Kingly Court may find that water through a ceiling can damage stock and close a sales floor, so the source needs finding fast. For site and facilities teams at buildings such as St Josephs Catholic Primary School, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.

Why get it checked now?
A small drip today can be a bigger leak after the next storm. Wind lifts loose slates further and gaps widen. An investigation now gives you time to plan the work. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. By the time a ceiling stains, the timbers underneath may have been wet for a while.
Roof leak investigation starts from £150, including VAT. The final price depends on the size and height of the roof, access and which survey you book.

- 5,000+ surveys completed
- Covered by professional indemnity and public liability insurance

What happens on the day
The visit has one job: to see as much of the leaking roof as can be seen safely and record it clearly. Notes and photographs go into the written report. The visit typically takes 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 rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents when you book.
- You let us know where the water shows and when it appears.
- The visit starts indoors, at the stain and in the loft.
- 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.
Before the survey
- Keep pets out of the way during the survey
- Jot down any questions you want answered
- Let us know about parking near the property

Seven Dials: your questions answered
Is Seven Dials in the area you cover?
Yes. Our area covers London and South East England, and Seven Dials is part of that. You can call 07833 053749 or email us with the address and a few details, and we’ll talk through which survey suits.
Is my home in Seven Dials listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
Will I get photos?
Yes. We photograph the roof as we go, and the report uses them to show each finding.
What does a roof survey cost?
Prices start from £150, including VAT. What you pay for your roof depends on its size, height, access and the package, confirmed before anything is booked.
Do you carry professional indemnity insurance?
We hold professional indemnity and public liability insurance, for every survey we carry out.
Do you climb onto every roof?
Only where it is safe to do so. We inspect whatever is safely visible: from the ground, from windows, from inside the roof space, from the roof where it’s safe and by drone where it applies. The report says if anything couldn’t be seen.
I live in a flat. Can you survey the roof?
Yes, once whoever controls the roof agrees access. We look at the parts we’re given access to.
Do you need a roof leak investigation in Seven Dials?
Flashings are one of the commonest sources of roof leaks. Lead or mortar closes the gap wherever a roof meets a wall, chimney or dormer. When lead lifts or splits, or a mortar fillet cracks, rain runs straight in, often well away from where it shows.
Things that often lead to a survey include:
- Brown rings on upstairs ceilings
- Leaks that appear only in driving rain
- Water through the ceiling under a flat roof
- Damp patches next to the stack
If you own a rental within reach of Tottenham Court Road station, tracing a leak quickly matters when a tenant is living with it.
What to check before booking
- Will they check the loft as well as the outside?
- When you’ll get the report
- What happens after the report arrives
