Flat roof surveys for homes and businesses in Gunnersbury
We inspect a flat roof from wherever it can be seen safely: from the roof itself where that is safe, from windows and nearby vantage points, and from inside where there’s access. Fragile rooflights and fragile sheets are never walked on. Where any area can’t be viewed safely, we say so in the report, so the limits of the survey are clear. Common reasons to book are blistering in felt or asphalt and damaged trims at the roof edge, on GRP fibreglass, mastic asphalt and single-ply membranes.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, each with its own weak points. In Gunnersbury, as anywhere in London, the right approach depends on what the roof is made of. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
Pictures do a lot of the work in our reports, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

Before and after the survey
Small things make a difference, both for the survey and for the roof itself. Our tips:
- Look for standing water a day after rain
- Book a survey every few years
- Check the outlets after the leaves fall
- File the paperwork for the roof and any repairs
After the visit, we write up the report with photos of what we found. It covers the type of covering, its condition and each defect, with our recommendations. Turnaround is within 48 hours for a Basic Survey, 24 to 48 hours for a Standard Survey and the same day for a Premium Survey.
Clear leaves and silt from outlets and gutters, above all in autumn. A flat roof that drains well wears much more slowly.
The survey, step by step
Once we’ve finished looking, we write up our findings as a report with photos, sent to you by email. On timing, most surveys take an hour or two at most homes; commercial roofs usually need 3–4 hours. In converted houses and mansion blocks, the loft hatch is frequently on a shared landing. If that applies to your building, it is useful to agree access with the neighbours or the managing agent first. Otherwise, the visit in Gunnersbury runs like any other.
- We start with the address and, on larger roofs, the roof area and access.
- Inside, we look for signs of water under the roof where we can reach.
- The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
- Each defect is photographed and its likely cause noted.
- The report explains the condition and recommends what to do first.
Before we arrive
- Gather any invoices or paperwork from past roof work
- Clear the way to the loft hatch
- Agree roof access with the managing agent if it’s shared

Advice
What a flat roof survey looks like in Gunnersbury
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. If your home in Gunnersbury is one of them, bay roofs, hips and later dormers each have their own details. Next to the main roofs there is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. About 0.7 miles north-west lies Gunnersbury Park, a reminder of how long the area around Gunnersbury has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area.
If you look after a shop, office or commercial unit, for instance near Livat Hammersmith, flat roofs over shops and units are easy to forget until water comes through a ceiling. For an older house near a landmark such as St Michael's Church, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

FAQs for Gunnersbury
Can you look at the flat roof of a hotel or office near Gunnersbury?
Yes. As well as homes, we check flat roofs on offices, hotels, blocks of flats and commercial units. For a bigger roof, you’ll get a quote based on the building, and roof access is agreed with you ahead of the visit.
Is parking a problem for a survey in Gunnersbury?
Parking in Gunnersbury, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Does this replace a RICS home survey?
No. It’s a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
Do you survey roofs on blocks of flats?
Yes, if the freeholder or managing agent agrees access. On a shared roof we can only inspect the parts we’re allowed to reach.
How do I book a survey in Gunnersbury?
Just phone 07833 053749 or drop us an email with the address. After a few questions, we confirm the price and fix a day.
What happens after the survey?
We email you the written report with photographs and recommendations. It is yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Do you use drones?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.
When you need someone else
It is a careful look at the flat roof, not the whole story. Its limits include:
- Parts of the roof that are not safe to walk on or view

Helping us price your survey
You do not need to know any roofing terms. Just tell us:
- Pictures of the roof from a safe spot, if you have them
- Dates you’re working to, such as exchange
- Where water is showing inside, if it is
- How the loft is reached, if there is one

Signs you need a flat roof survey in Gunnersbury
No flat roof covering lasts for ever. Around 15 to 20 years is common for felt, while EPDM often lasts 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.
Things that often lead to a survey include:
- Blisters and bubbles in the covering
- Standing water left after rain
- Failed seals around rooflight kerbs
- Cracked or split membrane
For hotels and guest houses around Gunnersbury, a roof problem found early is far less disruptive than one found by a guest, so it’s worth knowing the roof’s condition.
Questions to ask before booking
- What insurance they carry
- Is VAT included in the price?
- What’s outside the scope of the survey
- Whether you can ask questions once you have the report
