Flat Roof Survey in Perivale
A careful look at the flat roof at your property in Perivale, and put it all in a written report with photos.
- A sagging deck under the covering
- Raised blisters across the surface
- Ponding water that does not drain away
What happens on the day
Photos are taken throughout the visit, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available, including by drone where it’s applicable and the weather allows. A typical visit takes roughly 1–2 hours for a small flat roof at home, and longer for a large commercial one. In a London conversion, the way into the roof space is often from a communal landing or the top flat. Where that is the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- We check the rooms or spaces under the roof for staining where there is access.
- We view the roof from safe positions and never walk on fragile surfaces.
- We record every defect with a photo and its likely cause.
- You get a report setting out the condition and our recommendations, in order of urgency.
Preparing for the visit
- Let us know about parking near the property
- Make sure we can get to the back of the property
- Leave a clear route to the loft
Booking a survey
Prices start from £150, including VAT. The exact figure depends on the roof and the package, and you can call 07833 053749 or email us to find out.

Flat roof survey in Perivale
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. We quote commercial roofs on their size and how they’re reached, so please ring 07833 053749 or use the contact form with the address and an idea of the roof’s size. We survey mastic asphalt, felt flat roofs and EPDM rubber, and common reasons people get in touch are ponding water that doesn’t drain away and loose or cracked edge trims.
Offices, shops and blocks of flats across London often have large flat roofs with plant, rooflights and walkways. Each pipe, upstand and fixing through the covering is a possible weak point. In Perivale, roof access is agreed with the building manager or owner beforehand. Plant bases, rooflights and cable entries are all places where water can get in.
Nothing in the report is left vague: where something needs attention, it says so plainly, and where it can wait, that’s said too.

Flat roof surveys around Perivale
The wider area around Perivale has a long history of building, with Pitzhanger Manor about 2 miles south. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, frequently with hipped roofs of clay or concrete tiles. If your home in Perivale is one of them, bay roofs, hips and later dormers each have their own details. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
For businesses in and around places such as London Designer Outlet, the flat roofs over shops and commercial units are worth checking before a leak, not after. As a London address, Perivale can be tricky for parking: a visitor permit or a nearby bay makes the day easier. If you look after a building like St John Fisher Catholic Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Landlords, agents and block managers in Perivale
Landlords, agents and building managers in Perivale and across Greater London can book any of our surveys. For a price for a let property or a block, phone 07833 053749 or drop us an email.
If the property is let, the agent or a tenant can let us in, at a time agreed beforehand. We survey on weekdays and at weekends, which can make access easier.
Honest limits
This is not a RICS building survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Whether old sheeting or boards contain asbestos
- A promise that the roof will not leak in future
- Fragile surfaces, which we do not walk on
Not sure which survey suits your roof? You can ring 07833 053749 or drop us an email and we will tell you before you book. The full list of what we check.
What we look at
- Upstands and outlets
- Single-ply membranes
- Felt flat roofs
- EPDM rubber
- GRP fibreglass
- Mastic asphalt
How the survey changes by roof type
Rooflights and upstands
Where a flat roof meets a wall, the upstand has to stay sealed as the building moves. We check for splits, gaps and loose flashings above the upstand.
EPDM rubber
A rubber roof can last 30 to 50 years, provided its details were done well. Those details are where we focus.
How we price flat roof surveys
A few things affect what a survey costs:
- The type of building, from a house to a block or an office
- How big the roof is
- Features like valleys, chimneys, dormers and parapets
- How tall the building is and how easy the roof is to see
Simple, low roofs take less time to survey than tall or complicated ones, and the package you pick makes a difference too. The price is always agreed first.
What to let us know when you get in touch
What helps most when you contact us:
- When you need the report by
- How the loft is reached, if there is one
- The address and postcode of the property
- The style of property, from a terrace to a block
Once you know what you need, ring 07833 053749 or use the contact form. From there it is a case of choosing a package, agreeing the price and fixing a day.
Common questions in Perivale
Will parking be an issue for a roof survey in Perivale?
London parking needs a little planning, so let us know about permits, bays or a driveway as you book. That way the visit can be planned around it.
Do you carry out roof surveys in Perivale?
Yes. We cover the whole of London and South East England, and Perivale is part of that. Just ring 07833 053749 or email us and let us know about the property, and we will talk through which survey suits.
Can you survey in bad weather?
It can, depending on the survey. Drone flights need calm, dry weather, and thermal imaging works best after a sunny day, with a dry roof and little wind. If the conditions aren’t right, we’ll talk to you about another date.
Does someone need to be in?
Not always. If we only need the outside, we can agree that beforehand, but anything inside needs someone there to give access.
Can you give me structural calculations?
No. We point out what can be seen, such as sagging or deflection, but we’re not structural engineers and don’t carry out calculations. Where an engineer is needed, we say so in the report.
What’s in the report?
It works through the roof part by part, in writing and with photos, finishing with recommendations. The most urgent items are made clear.
Will the survey show why my flat roof is leaking?
Our survey looks across the whole roof, not only above the stain. Every split, lap, upstand, outlet and rooflight we can see is looked at. Where nothing visible explains the leak, the report says what to try next.
Practical tips
Here are a few things we’d tell any owner, before and after a survey:
- Treat rooflights and old sheeting as fragile
- Book a survey every few years
- Check from a window for ponding after heavy rain
- Check ceilings under the roof for damp patches
You can use the report to ask roofers to quote for the same work. With each roofer working from the same list, comparing quotes is simpler. It is your choice who carries out the work and when.
Clear leaves and silt from outlets and gutters, above all in autumn. A flat roof that drains well wears much more slowly.
