Flat roof surveys for homes and businesses in Hillingdon
Our flat roof survey checks the waterproof covering and every detail around it, from edges and upstands to outlets and rooflights. We cover felt, mastic asphalt, EPDM rubber, GRP fibreglass and single-ply roofs. It suits a small roof over an extension or garage as well as a large one over flats, offices or units. You get a report with photos and our recommendations. If you are worried about a sagging deck under the covering and standing water left after rain, we can find out what’s behind it.
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 Hillingdon, access is agreed with whoever manages the roof ahead of the visit. Plant bases, rooflights and cable entries are all places where water can get in.
Where we can’t see part of the flat roof, the report says so. That way, it’s clear what was covered and what wasn’t.

How the survey changes by roof type
Felt and built-up roofs
Felt roofs often last around 15 to 20 years, depending on how they were laid and looked after. Our report sets out its condition and the areas most at risk.
Single-ply membranes
Many offices, units and newer flats have a single-ply PVC or TPO roof. We check the welded laps, the edges, the fixings and any punctures.
When to book a survey in Hillingdon
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. Either way, you get a clear record of the roof, with photographs.
These are some of the problems a survey can pick up:
- Raised blisters across the surface
- Gaps at upstands and abutments
- Blocked or damaged outlets
- Ponding water that doesn’t drain away
If you own a rental within reach of West Drayton station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
Questions to ask before you book
- Is there a chance to talk the report through?
- Whether they hold professional indemnity and public liability insurance
- How much experience they have with roofs like yours
- How they plan to inspect the roof safely
Why act early in Hillingdon
A small split in a flat roof is typically a modest job when it is found early. Left alone, water can soak the insulation and the deck, and the job grows. Surveying it now tells you where you stand. London’s older roofs often have bitumen felt underlay or none at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left alone, that means wet timbers and plaster, which is a far bigger job than the roof fault itself.
There are three survey packages: Basic from £150, Standard from £250 and Premium from £400, with VAT included. The price for your roof depends on its size, access and what you want to find out.

What a survey costs
We confirm the price for the job before booking. These are the things that affect it:
- Which survey package you book
- Whether it is a home or a commercial building
- Extensions, dormers and garages with roofs of their own
- The shape of the roof and its details
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before you book.
Helping us price your survey
Getting the details right at the start saves time. Please include:
- The style of property, from a terrace to a block
- Where the property is, with the postcode
- What’s prompted the survey
- Access details, like a loft hatch or a shared roof
To book a survey, phone 07833 053749 or send us an email with the address and what you’d like to know about the roof. You’ll know the price before anything is booked.
Flat roof surveys in Hillingdon: local notes
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Historic houses such as Ickenham Hall, about 1.8 miles north, show how far back building in the area around Hillingdon goes. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area.
Anyone responsible for a site like Abbotsfield School for Boys will know that schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks. For businesses in and around places like The Chimes, outlets and upstands on commercial flat roofs are the places to check before trouble starts.

What we do, step by step
The visit has one job: 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. The visit usually takes between one and two hours for a small flat roof at home, and longer for a large commercial one. In Hillingdon, visits are available on weekdays and at weekends. 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.
- 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.
- 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
- Make sure we can get to the back of the property
- If it isn’t your property yet, arrange access through the agent
- Note where any stains or damp appear

Common questions in Hillingdon
Is Hillingdon in the area you cover?
Yes, Hillingdon is within the area we cover. We cover the whole of London and South East England. Just ring 07833 053749 or use the contact form and tell us about the property, and we’ll talk through which survey suits.
Will parking be an issue for a roof survey in Hillingdon?
Parking in Hillingdon, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Is ponding on a flat roof a problem?
Ponding is worth looking into. It often means a blocked outlet, poor falls or a dipping deck, and water that sits wears the covering sooner. We record where it sits and the likely cause.
Will you fly a drone over my roof?
Yes, where it is applicable. 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.
Will I get photos?
Yes. Photos are taken throughout the survey, and the report uses them to show each finding alongside our recommendations.
Do I need to be at home?
Not always. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
Does a flat roof survey replace a RICS survey?
No. Our survey covers the flat roof only. It isn’t a RICS Level 2 or 3 survey of the whole building, and it isn’t a structural engineer’s report. Many buyers use it alongside a building survey.
What we cannot see
Without opening up the roof, some things stay hidden, and that sets some limits:
- Structural calculations, which need a structural engineer
- Parts of the roof that aren’t safe to walk on or view
- The condition of the deck or insulation hidden under the covering
