Flat Roof Survey in Hammersmith
Get a clear view of the flat roof at a property in Hammersmith. We visit on weekdays and at weekends.
- Dips that suggest the deck is deflecting
- Loose or cracked edge trims
- Outlets that hold water back
Leave it or get it looked at?
Standing water on a flat roof rarely sorts itself out. Most often it means blocked outlets, poor falls or a deck that is dipping, and each wet season wears the covering further. Finding the cause now keeps more options open. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. When the stain finally shows, the damage underneath is often older than it looks.
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 it can be reached and seen safely. Flat roof survey starts from £150, including VAT.

Flat roof survey in Hammersmith: what you get
Standing water is one of the first things we look for on a flat roof. It can mean the falls were never right, an outlet is blocked or the deck has started to sag. The survey notes any ponding, the state of each outlet and any dips that hint at a sagging deck. Where the deck may be a structural issue, our report says a structural engineer should look at it. Common reasons to book are splits, cracks and crazing and outlets choked with leaves and silt, on mastic asphalt, GRP fibreglass and single-ply membranes.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Every penetration and upstand is a place where a membrane can fail. For a building in Hammersmith, access is agreed with whoever manages the roof before the visit. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
How fast the report arrives depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

Flat roof surveys in Hammersmith: local notes
The wider area around Hammersmith has a long history of building, with Kelmscott House about 0.5 miles south-west. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first. There are several hotels within about a mile and a half of Hammersmith, and like offices and blocks, hotels often sit under flat roofs. If you look after one, a leak through a flat roof can put a room out of use.
For landlords with property near Kensington Olympia station, the flat roof over a let home is worth a look before it becomes a tenant complaint. If your house is among the older ones in the streets near Church of the Holy Innocents, the flat roofs on later extensions tend to wear out long before the main roof.
Hammersmith is about 1 mile west of Kensington, in Greater London. In Hammersmith, as across Greater London, every roof gets the same careful survey. Hammersmith is one of the towns and villages in Greater London we cover for flat roof surveys. You can also see our page for London.

Common questions in Hammersmith
Will parking be an issue for a roof survey in Hammersmith?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available as you book.
How do I find out if my home in Hammersmith is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
Do you look in the roof space?
If there’s a loft and safe access to it, yes. From inside, the underside of the roof often shows damp, staining or daylight that can’t be seen from outside.
Do you give a life expectancy for the roof?
We do not give a fixed number of years, because so much depends on upkeep, exposure and workmanship. Our report describes the condition and what needs doing, and when.
Can you find where water is getting through my flat roof?
We check the covering and every detail where leaks commonly start, recording anything that could let water through. If the source is hidden, we may suggest a leak investigation or electronic leak detection.
What insurance do you have?
We are covered by professional indemnity and public liability insurance, for every survey we carry out.
Can you survey any kind of flat roof?
We survey felt and built-up roofs, mastic asphalt, EPDM rubber, GRP fibreglass and single-ply PVC and TPO. Not sure what yours is? We will tell you in the report.
What this survey cannot tell you
A survey is a proper look at the flat roof, but it can’t do everything. The main limits are:

- What’s under the membrane without opening it up
- A promise that the roof will not leak in future
If you’re not sure which survey you need, ring 07833 053749 or drop us an email and we’ll give you a straight answer before booking. The full list of what we check.

Surveys for landlords and agents in Hammersmith

Businesses and commercial landlords can book us too. Bigger roofs take more time, and they’re priced for the size.
What affects the price in Hammersmith
Our packages start from £150, inc. VAT. The price for your roof depends on:

- What’s prompted the survey

Our price is from £150, including VAT. What you pay depends on the roof’s size, access and the package, so call 07833 053749 or email us with the details.
How it works
The aim of the visit is simple: to see as much of the flat roof as can be seen safely and record it clearly. Everything we note and photograph goes into the written report. It typically takes an hour or two for a small flat roof at home, and longer for a large commercial one. London terraces rarely offer a view of the whole roof from one spot, so in Hammersmith we work round the house, using the street, the windows, the loft and any safe vantage point behind it. If other people live in the building, let us know who can let us into the shared parts.
- We agree the roof to be surveyed, its use and any leaks you know about.
- We look at the roof from ground level, windows and the roof where it’s safe.
- We check the covering for splits, blisters, ponding and wear.
- Upstands, outlets, edge trims and rooflights are checked and photographed.
- The report, with photos and recommendations, comes to you by email.
Preparing for the visit
- Make a note of anything you’d like us to look at
- Make sure we can get to the back of the property
- If the roof is shared, arrange access with whoever manages the building

Do you need a flat roof survey in Hammersmith?
No flat roof covering lasts for ever. Felt roofs often last around 15 to 20 years, EPDM often 30 to 50 years and GRP up to about 30, though workmanship and upkeep make a big difference. We can tell you how your roof is doing, whatever its age.
Most people get in touch after spotting one of these:
- Signs of deflection in the roof deck
- Gaps at upstands and abutments
- Splits, cracks and crazing
- Failed seals around rooflight kerbs
Take a building like Corona Theatre School: a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.
