Flat roof survey in North Kensington: what you get
Ponding is frequently the first sign that something on a flat roof is not right. It can mean the falls were never right, an outlet is blocked or the deck has started to sag. We record where water sits, check the outlets and look for dips that suggest deflection. If the deck itself looks like a structural concern, we will recommend a structural engineer. If you’ve noticed blisters and bubbles in the covering and blocked or damaged outlets, a survey will tell you what’s going on.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, and each fails in its own way. Which one is on a roof in North Kensington shapes how it’s checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
The report works through the roof section by section, from the main slopes down to the gutters and outlets, with a note and a photo for each point. It records what’s sound as well as what isn’t.

North Kensington: your questions answered
Do you cover commercial flat roofs around North Kensington?
Yes, commercial flat roofs are part of what we cover. Larger commercial roofs are quoted for the building.
How do I find out if my home in North Kensington is listed?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
How long is the visit?
That depends on the size and shape of the roof, but most surveys take between one and two hours at a typical home, with bigger or more complicated roofs taking longer. The written report follows by email.
Is it the same as a RICS Level 2 or Level 3 survey?
No. It is a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof and can sit alongside a RICS survey.
How do I arrange a flat roof survey in North Kensington?
The quickest way is to ring 07833 053749 or drop us an email. Give us the address and a few details about the roof, and we will take it from there. Surveys run on any day of the week.
How soon will I get the report?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline as you book.
Will you fly a drone over my roof?
Yes, where applicable and safe. We fly a sub-250g drone and we’re a CAA-registered drone operator (Flyer ID and Operator ID). It’s included in the Drone Roof Survey and, where it applies, the Premium Survey.

With a portfolio of properties, surveys can be booked for more than one address. To arrange surveys for several addresses, ring 07833 053749 or send us an email.
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work with less disruption.
How the survey works
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. In total, it takes between one and two hours for most houses, and more on a big or complicated roof. Surveys in North Kensington can be booked for any day of the week. It helps if you can point us to a visitor permit or a nearby bay, and to clear a path to the loft hatch. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- We start with the details: the address, the roof’s use and any leaks or stains.
- We check the roof from wherever it can safely be seen.
- The covering, falls, upstands, outlets, edge trims and rooflights are checked and photographed.
- Where there’s safe access, we look at the ceilings and spaces below for signs of water.
- You get a written report with photos and our recommendations.
How to prepare
- Jot down any questions you want answered
- If you’re buying, let the agent know when we’re coming
- Clear the way to the loft hatch

Local flat roofs in North Kensington
Within a mile and a half or so of North Kensington there are several hotels, and like offices and blocks, hotels often sit under flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use. Historic houses such as Kensington Palace, about 1.9 miles south-east, show how far back building in the area around North Kensington goes. 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 own a rental within reach of Kensal Green station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. For site and facilities teams at buildings like Barlby Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Common roof problems in North Kensington
The surface of a flat roof heats up and cools down far more than the rooms below. This constant movement works at laps, seams and board joints, and in time it can open up splits and cracks. Coverings that have hardened with age tend to suffer most.
It is worth booking a survey if you’ve seen:
- Cracked or split membrane
- Outlets choked with leaves and silt
- Failed seals around rooflight kerbs
- Raised blisters across the surface
If you own one of the older houses in the streets near Dissenters' Chapel, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
Before you book anyone
- What insurance they carry
- Whether the inside of the roof is included
- Is VAT included in the price?
- Whether you get a written report with photos
Leave it or get it looked at?
By the time a flat roof leak shows indoors, water has already passed through the roof build-up. We can pick up worn covering and failing details sooner, while there is still time to plan the work. Blocked gutters and hoppers on London houses overflow and soak brickwork, which can lead to damp inside. A blocked outlet ignored for a winter or two can mean damp walls inside.
A Basic Survey starts from £150, with VAT included. The Standard Survey starts from £250 and the Premium Survey from £400, both with VAT included. You’ll know the price for the job before booking.

Useful tips for North Kensington property owners
Some practical points come up on survey after survey. They apply to most roofs:
- Check new fixings through the roof are properly sealed
- Keep records of when the roof was laid and what work has been done
- Never stand on rooflights or fragile sheeting
- Watch the ceilings below the flat roof for stains
Many people send the report to two or three roofers for quotes. With each roofer working from the same list, comparing quotes is simpler. It is your choice who carries out the work and when.
Check the roof from a window after a downpour. If water is still there a day or two later, have it checked.
Should I look at the roof myself first?
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
Your own check is a good start, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground, and those are details a survey looks at closely.
