Roof leak investigation in Mayfair
Our roof leak investigations cover Mayfair and the wider South East. We visit on weekdays, Saturdays and Sundays. The investigation covers inside and out, from the stain to the likely entry points. The findings come in a written report with photos. If it is leaking right now, contain the water and keep it clear of electrics, then call 07833 053749 or send us an email to arrange a visit. We survey chimney stacks, the roof space and flat roof details, and people most often book us about damp on a chimney breast and wet patches high on an inside wall.
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 usually exclude wear and tear. That is as true in Mayfair as anywhere in London. A written record with photographs helps you explain what was found to whoever deals with it next.
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.

Mayfair: your questions answered
Do you carry out roof surveys in Mayfair?
Yes. We cover the whole of London and South East England, and Mayfair is part of that. Just phone 07833 053749 or use the contact form and let us know about the property, and we will talk through which survey suits.
How do I find out if my home in Mayfair 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.
How should I prepare for the leak investigation?
Note when the leak appears and what the weather was doing. Move stored items away from the loft hatch. Keep away from any light or socket that water is reaching.
When does the report arrive?
It depends on the package: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. Reports are sent by email.
How many surveys have you done?
Over 5,000 surveys so far, across 20+ years of surveying roofs.
Do you climb onto every roof?
Only when it’s safe. Safety comes first, and fragile or steep roofs cannot always be walked on. We use safe viewpoints, the roof space and a drone where it applies, and the report records anything we couldn’t see.
Can you tell me if my roof has asbestos?
No. We can flag materials that might contain asbestos, but confirming it is a job for a specialist asbestos surveyor. It may be present in buildings built or refurbished before 2000.
Can I check my roof myself?
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That is where a survey comes in.

How it works
It helps to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. Most visits take roughly 1–2 hours, more where the leak is intermittent or the roof is large. In converted houses and mansion blocks, the loft hatch is often on a shared landing. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- You pick a Basic, Standard or Premium Survey.
- We agree a date, including weekends.
- The investigation works from the stain back to the roof.
- Moisture detection and thermal imaging are used where your package includes them and they help.
- The report explains the likely entry point and what needs attention.
Before we arrive
- If you’re buying, check with the agent that we can get in
- Tell us about any leaks, stains or damp patches you know of
- Tell us where we can park nearby
Arrange a survey
Getting a price is simple: just call 07833 053749 or send us an email and give us a few details about the property and we’ll point you to the right survey. We confirm the price before anything is booked.

Practical tips
Over many surveys, some simple habits stand out as worth the effort:
- Catch drips in a bucket and protect the floor
- Have an electrician check any wet fittings
- Write down the wind direction and rain when it leaks
- Tell us if there are tanks or pipes in the loft
Any roofer you ask to quote can work from the report. The photos show the defects and where they are, so the repair is aimed at the cause.
After a storm, check the roof from the garden and the street. Slipped slates, lifted ridge tiles and debris on the ground are signs to act on. Prompt repairs stop gaps turning into leaks.
How we price roof leak investigations
To price your survey, we check:
- The use of thermal imaging or a drone
- The roof’s overall size
- Whether it is a home or a commercial building
- Chimneys, valleys, parapets and other details
Prices start from £150, including VAT. The final price depends on the size and height of the roof, access and the package you choose.
What to let us know when you get in touch
A little information up front helps. Please include:
- Any photos you have, taken from ground level or a window
- Dates you’re working to, such as exchange
- Any stains, drips or damp patches you’ve seen indoors
- Access details, such as a loft hatch or a shared roof
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. For any other survey, just ring 07833 053749 or email us when you’re ready.
Why it’s worth a survey now in Mayfair
Guesswork repairs are a common reason leaks keep coming back. Because water travels, the real entry point may be somewhere else. An investigation finds the likely cause first, so the repair is aimed at the right place. London’s older roofs often have bitumen felt underlay or none at all, so a slipped slate can soon mean water inside. Left unchecked, water soaks into timber and plaster and the damage spreads.
One thing that affects the price is the package: Basic from £150, Standard from £250 or Premium from £400, all with VAT included. Size, height and access can affect the price too.
Why book with us
- Professional indemnity and public liability insurance
- Thermal imaging and drone inspection where they help
- Surveys seven days a week
- Independent findings on the roof’s condition

Roof leak investigations around Mayfair
Many homes in inner London are Victorian and Edwardian terraces, often with Welsh slate roofs. Behind many of their parapets sit butterfly roofs and valley gutters that cannot be seen from the pavement. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. Different coverings let water in at different points, which shapes where the search starts. The wider area around Mayfair has a long history of building, with Handel Hendrix House about 0.2 miles north. 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 a listed home or one in a conservation area may need consent for changes of material.
Anyone responsible for a site like LITE Regal International School will know that tracing a leak on a big roof starts with where the water appears and works back. If you own a rental within reach of Bond Street station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused.
Mayfair is about 1 mile south-east of City of Westminster, in Greater London. Wherever you are in Mayfair, we can come and survey your property, on a weekday, Saturday or Sunday. Our area takes in places right across Greater London, large and small.

Local landmarks in Mayfair
In Mayfair, that means homes and buildings near Royal College of Nursing Library & Museum, Coach and Horses pub and St George's Church of England Primary School and the streets around them. Nearby too are Green Park (0.5 miles south) and The St Marylebone CofE School (0.8 miles north). There’s a railway station in Mayfair itself: Bond Street station.

What we’re asked to look at in Mayfair
A roof valley collects the rain from two slopes. Worn lead, cracked linings or a build-up of leaves and moss can push water under the slates or tiles. Leaks from valleys frequently show up some distance away inside.
A survey makes sense if you’ve noticed:
- Damp on a chimney breast
- Water that shows only in certain storms
- Ceiling stains that grow after rain
- Wet patches high on an inside wall
If you look after a shop, office or commercial unit, for example near Kingly Court, finding where water is getting in quickly keeps disruption down.
Choosing a roof surveyor
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- Will they check the loft as well as the outside?
- What the survey will not cover
- Are they insured for the work?
