About our roof leak investigation in Knightsbridge
Water is good at hiding where it gets in. Water often travels along timbers or underlay before it finds a way down, so a ceiling stain is rarely directly below the cause. We follow it back towards where it starts, one likely route at a time. Patching the spot above the stain often misses the real cause. Tracing the route first means any work can be aimed at the right place. We survey flat roof details, chimney stacks and slate and tile slopes, and the problems we’re asked to look at most are wet patches on loft insulation and leaks that appear only in driving rain.
In converted houses and blocks across London, water from a roof can run a long way before it shows on a ceiling, sometimes in a different flat from the one below the defect. That makes the source hard to pin down, and finding it matters for whoever has to deal with it. In Knightsbridge, we inspect what we can reach safely and are given access to. Let us know when the water shows, and in what kind of weather.
Every survey ends with a written report, with photographs, sent by email. It explains the condition of the leaking roof, the defects we found and what we recommend.

Questions from Knightsbridge
Is Knightsbridge in the area you cover?
Yes, Knightsbridge is within the area we cover. We survey roofs across London and South East England. You can phone 07833 053749 or drop us an email with the address and some details.
Can parking be tricky for a visit in Knightsbridge?
Normally it’s manageable with a little notice. Let us know the parking rules on your street and we will work around them.
What happens after the survey?
You will get the report by email. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation.
How soon will I get the report?
Each package has its own report time. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. If you have a deadline, such as an exchange date, let us know when you book.
Why is the stain in a different place from the leak?
Rain that gets in will run along whatever it lands on. On a flat roof it can travel under the covering before it finds a way through the ceiling. Following that route is what our investigation does.
What insurance do you have?
Our surveys are covered by professional indemnity and public liability insurance. If you need details for a managing agent or a building owner, just ask.
Can you find a leak when it is not raining?
In many cases, yes. Stains, tide marks, damp timbers and moisture readings typically point the way. Intermittent leaks can be harder, so photos and notes from when it leaks help a lot.
Prices for roof leak investigations in Knightsbridge
To price your survey, we check:
- Chimneys, valleys, parapets and other details
- The package you choose: Basic, Standard or Premium
- Commercial roofs and larger buildings
- How many separate roofs there are, like extensions, dormers and garages
For a price for your roof in Knightsbridge, call 07833 053749 or send us an email with the address and a few details. The price is agreed before a date is set.
What to tell us when you contact us
We will normally ask about:
- How the loft is reached, if there is one
- The reason for the survey, such as buying, a leak or storm damage
- Your timetable, such as an exchange date
- The address and postcode of the property
Getting a price is simple: just ring 07833 053749 or email us, let us know about the property and we will suggest the right survey. The price is agreed up front.
DIY checks: what’s safe
The one thing to avoid is getting up close. Roofs are fragile and slippery. That part is for a survey, using safe viewpoints and a drone where it applies.
It is useful to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us when you book and it will help the survey.

What else we do in Knightsbridge
What we do, step by step
A survey visit follows a simple order: we listen to what’s been worrying you, inspect the roof from each safe vantage point, photograph what we find and make notes for the report. It normally takes about one to two hours, more where the leak is intermittent or the roof is large. Surveys in Knightsbridge can be booked for any day of the week. London parking is often by permit or pay-and-display, so it helps to know what’s near you. Upstairs rooms at the back are useful too, as they frequently give the best view of a rear addition.
- We help you choose the package that suits the leak.
- A visit is booked for a weekday, Saturday or Sunday.
- We inspect inside and out, starting from the stain.
- Where it is useful and included, we take moisture readings and use thermal imaging.

Preparing for the visit

Why act early in Knightsbridge
A leak rarely stays small. Wet timbers start to decay, plaster softens and insulation stops working. Tracing it now means less to put right later. Many older London roofs have only old felt under the slates, or no underlay at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left alone, that means wet timbers and plaster, which is a far bigger job than the roof fault itself.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Our price is from £150, including VAT.
What you get with us

What we look for on each type of roof
Flat roof upstands and outlets
Outlets drain a flat roof. When one blocks, water ponds and finds any weak spot. Outlets and the area around them are checked.
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 Knightsbridge
The wider area around Knightsbridge has a long history of building, with Apsley House about 0.5 miles east. 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. 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 can’t be seen from the pavement. If your home in Knightsbridge 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.
Trees in and around Royal Parks of London shed leaves that can end up in nearby gutters. If you own a rental within reach of London Victoria station, tracing a leak quickly matters when a tenant is living with it. Take a building like Hellenic College of London: on a building that size, finding the source of a drip means looking well beyond the stain.

Useful tips for Knightsbridge property owners
Getting the most from a roof leak investigation starts before we arrive and carries on afterwards. Tips:
- Protect furniture and flooring under the leak
- Mention any plumbing above the damp area
- Keep a photo record of the damp patch
- Note the weather when the leak shows
The report gives whoever carries out the work a clear starting point. They’ll see exactly where the problem is, so the repair is aimed at the cause.
Have flashings and flat roofs looked at every few years. They’re where most leaks start, and catching wear early keeps water out.
