Mayfair Flat Roof Survey
Surveys of flat roofs on homes, extensions and commercial buildings around Mayfair, with a written report you can act on. Weekday and weekend visits available.
- A sagging deck under the covering
- Outlets choked with leaves and silt
- Blistering in felt or asphalt
Why get it checked now?
Waiting for a stain inside means the water has already got through the layers. We can pick up worn covering and failing details sooner, so you can plan the work rather than react to it. In Mayfair, as across London, an overflowing gutter soaks the wall below. A blocked outlet ignored for a winter or two can mean damp walls inside.
Price depends partly on the package: Basic from £150, Standard from £250 or Premium from £400, all including VAT. Size, height and access can affect the price too.
What you get with us
- Surveys on weekdays, Saturdays and Sundays
- Package prices that include VAT

About our flat roof survey in Mayfair
Each flat roof is looked at from the safest viewpoints we have: on the roof where it is safe, from windows and higher ground, and from the rooms below where we can reach them. Fragile rooflights and fragile sheets are never walked on. Where any area cannot be viewed safely, we say so in the report, so the limits of the survey are clear. We survey felt flat roofs, upstands and outlets and EPDM rubber, and common reasons people get in touch are splits, cracks and crazing and loose or cracked edge trims.
On a London roof terrace or a flat roof over a back addition, water often runs under the covering before it shows. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a block or conversion in Mayfair, the flat roof is often a shared part of the building.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

How we price flat roof surveys
All our prices include VAT. The things that change the price are:
- How many separate roofs there are, such as extensions, dormers and garages
- Any need for thermal images or a drone flight
- Basic, Standard or Premium
- The size of the roof
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package you pick makes a difference too. The price is always agreed first.
Getting in touch
A little information up front helps. It helps to include:
- Your postcode, so we can check access and travel
- Anything about access we should know
- What made you get in touch
- Any stains, drips or damp patches you’ve seen indoors
Getting a price is simple: just ring 07833 053749 or send us an email, let us know about the property and we’ll explain which survey suits. We confirm the price before anything is booked.
The survey, step by step
A survey visit follows a simple order: we listen to what’s been worrying you, inspect the roof from every safe viewpoint, take photographs as we go and make notes for the report. It typically takes about one to two hours on an ordinary house, or half a day or so for a commercial building. From the street, a London terrace usually shows only its front slope or parapet, so a visit in Mayfair moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, tell us who can let us into the shared parts.
- We agree the roof to be surveyed, its use and any leaks you know about.
- The roof is viewed from safe positions, including the roof itself where that’s safe.
- The covering is checked for wear, splits, blisters and standing water.
- We photograph and record the outlets, upstands, trims and rooflights.
- A written report with photos and recommendations is emailed to you.
Preparing for the visit
- Note where any stains or damp appear
- Agree roof access with the managing agent if it’s shared
- Have keys ready for side gates, garages or roof access doors

Letting agents can arrange access with tenants. Surveys run on weekdays and at weekends, which can make access easier.
Mayfair questions
Will parking be an issue for a roof survey in Mayfair?
Normally it’s manageable with a little notice. Let us know the parking rules on your street and we will work around them.
Do you cover commercial flat roofs around Mayfair?
Yes. As well as homes, we look at flat roofs on offices, hotels, blocks of flats and commercial units. Larger commercial roofs are quoted for the building.
Are you structural engineers?
No. Our survey isn’t a structural engineer’s report, and it doesn’t include calculations. We will recommend an engineer if we see signs that call for one.
Will I get photos?
Yes, plenty. Pictures sit next to the findings they show.
How fast do I get the report?
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. The report is emailed to you.
Do you carry out surveys on Saturdays and Sundays?
We carry out surveys seven days a week. To find a day that suits you, call 07833 053749 or drop us an email.
How long have you been surveying roofs?
We have completed more than 5,000 surveys, across 20+ years of surveying roofs.
How the survey changes by roof type
GRP fibreglass
GRP can crack if the deck beneath flexes or if the resin was laid too thin. We record any cracking and any signs of the deck moving.
Felt and built-up roofs
Built-up felt is one of the most common flat roof coverings on extensions, garages and dormers. We look for blistering, cracking, split laps and worn mineral surfacing.

Common roof problems in Mayfair
Flat roofs frequently get walked on for other jobs: cleaning windows, fitting aerials or air conditioning, or clearing gutters. Each visit can damage a covering not made for regular foot traffic. New brackets and fixings through the roof are another common source of leaks.
It is worth booking a survey if you’ve seen:
- Outlets that hold water back
- Splits, cracks and crazing
- Gaps at upstands and abutments
- Blistering in felt or asphalt
If you let a flat or house near Bond Street station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

- What exactly goes into their report
- When you will get the report
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
Flat roofs in Mayfair
Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. Behind many of their parapets sit butterfly roofs and valley gutters that can’t be seen from the pavement. If your home in Mayfair is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. About 0.2 miles north lies Handel Hendrix House, a reminder of how long the area around Mayfair has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
If you run a hotel or guest house in or near Mayfair, a roof problem can mean rooms out of use, so it pays to find faults before guests do. If you look after a building such as LITE Regal International School, a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.
