Flat roof survey in West Twyford: what you get
Offices, shops, industrial units and blocks of flats frequently sit under large flat roofs. On a roof like this, a survey shows where the covering is wearing, where water is ponding and which outlets need attention. The photographed record helps you plan and budget for work. Commercial roofs are quoted for their size and access, so it helps if you phone 07833 053749 or drop us an email with the address and a rough idea of the roof area. We’re often asked to look into leaks around rooflights and dips that suggest the deck is deflecting, on EPDM rubber, felt flat roofs and GRP fibreglass.
Offices, shops and blocks of flats across London frequently have large flat roofs with plant, rooflights and walkways. Every penetration and upstand is a place where a membrane can fail. In West Twyford, roof access is agreed with the building manager or owner beforehand. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
What you get is a clear record of the flat roof on the day we saw it. It’s useful straight away, and a good reference for later, such as when you want to compare after future work.

Should I look at the roof myself first?
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.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, as it helps a surveyor trace the cause.
What we do, step by step
Once we’ve finished looking, we write up our findings in a report with photos, emailed to you. On timing, most surveys take roughly 1–2 hours for a small flat roof at home, and longer for a large commercial one. Surveys in West Twyford can be booked for any day of the week. It helps if you can point us to a visitor permit or a nearby bay. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- First we go through the roof, what’s beneath it and any problems so far.
- We look at the roof from ground level, windows and the roof where it is safe.
- We check the covering for splits, blisters, ponding and wear.
- We photograph and record the outlets, upstands, trims and rooflights.
- A written report with photos and recommendations is emailed to you.
Getting ready for the survey
- Show us where any leaks or stains appear
- Leave side gates unlocked
- Check pets are kept safely away
Book a survey
If you have photos of the roof, send them over. Pictures from ground level or a window are fine; never climb up to get a better view. To get started, call 07833 053749 or email us.

Signs you need a flat roof survey in West Twyford
A buyer’s general survey often recommends a closer look at a flat roof. Owners and managing agents use a survey to plan upkeep, or ahead of a sale or a new lease. In each case, the report gives a written, photographed record of the roof’s condition.
Typical things we are asked to look at include:
- Leaks around rooflights
- Edge trims that have lifted or split
- Failed upstands where the roof meets a wall
- Raised blisters across the surface
Take an older house close to Church of St Mary: flat-roofed rear additions and dormers added over the years are worth checking.
Choosing a roof surveyor
- Whether the inside of the roof is included
- Is there a chance to talk the report through?
- How they plan to inspect the roof safely
- What the survey won’t cover
What a survey costs
To price your survey, we look at:
- Height and safe access
- House, block, shop or office
- Which survey package you book
- If the survey needs thermal imaging or a drone
One thing that affects the price is the package: from £150 for Basic, £250 for Standard and £400 for Premium, including VAT. Size, height and access can affect the price too.
Helping us price your survey
We’ll normally ask about:
- When you need the report by
- The kind of building and roof involved

Local flat roofs in West Twyford
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Historic houses such as Pitzhanger Manor, about 1.8 miles south-west, show how far back building in the area around West Twyford goes. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.
For businesses in and around places such as London Designer Outlet, outlets and upstands on commercial flat roofs are the places to check before trouble starts. If you own a rental within reach of Stonebridge Park station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

Your questions about flat roof surveys in West Twyford
Do you cover commercial flat roofs around West Twyford?
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.
Does a conservation area affect roof work in West Twyford?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Can you give me structural calculations?
No. We’re roof surveyors, not structural engineers, and it does not include calculations. If we see signs that need an engineer’s opinion, we’ll recommend one.
What’s in the survey report?
It sets out what we found, why it matters and what we recommend, with photographs throughout. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
What do I do with the report?
We email you the written report with photographs and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Do you look in the roof space?
Where it is relevant to the survey and there is safe access, yes. A clear path to the hatch helps, and if the loft can’t be reached safely, the report says so.
Do you use drones?
Where it is applicable and safe, yes. We fly a sub-250g drone and we’re a CAA-registered drone operator (Flyer ID and Operator ID). It is included in the Drone Roof Survey and, where it applies, the Premium Survey.
