Flat roof survey in Yiewsley, Greater London
Find out what’s going on with the flat roof before you decide what to do next. We carry out flat roof surveys in Yiewsley, with photographs and a clear written report.
- Gaps at upstands and abutments
- Splits, cracks and crazing
- Failed seals around rooflight kerbs
Signs you need a flat roof survey in Yiewsley
Flat roofs swing between hot and cold more than most parts of a building. This constant movement works at laps, seams and board joints, which can open splits and cracks over the years. Coverings that have hardened with age tend to suffer most.
Things that often lead to a survey include:
- Failed seals around rooflight kerbs
- Blistering in felt or asphalt
- Cracked or split membrane
- Edge trims that have lifted or split
Anyone responsible for a site like Rabbsfarm Primary School will know that schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.
Choosing a roof surveyor
- Are they insured for the work?
- Which viewpoints they use to see the roof
- Their track record with similar roofs
- Is VAT included in the price?
Flat roof surveys for homes and businesses in Yiewsley
Many commercial buildings and blocks of flats have big flat roofs. A survey of a roof this size picks out worn covering, standing water and outlets that 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 ring 07833 053749 or email us with the address and a rough idea of the roof area. Typical surveys look at leaks around rooflights and damaged trims at the roof edge, across GRP fibreglass, EPDM rubber and upstands and outlets.
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. For a building in Yiewsley, 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.
It is not only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend, so you can plan your next steps.

Should I look at the roof myself first?
It helps to keep a record: dates of leaks, photos from ground level and any work done on the roof. Share it with us when booking and it will help the survey.
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it.
How we price flat roof surveys
A few things affect what a survey costs:
- How many separate roofs there are, such as extensions, dormers and garages
- Whether thermal imaging or a drone is needed
- Whether it is a home or a commercial building
- The package you choose: Basic, Standard or Premium
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before booking.
What we need to know
What helps most when you contact us:
- Your timetable, such as an exchange date
- Pictures from the garden or a window, if you have them
- What made you get in touch
- The property’s address and postcode
To book a survey, ring 07833 053749 or use the contact form with the address and what you’d like to know about the roof. We’ll confirm the price before booking.
Your questions about flat roof surveys in Yiewsley
Do you cover Yiewsley?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Can parking be tricky for a visit in Yiewsley?
London parking needs a little planning, so let us know about permits, bays or a driveway when booking. The visit is then planned around what’s available.
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 happens next?
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.
How much does a flat roof survey cost in Yiewsley?
Flat roof survey starts from £150, including VAT. Our Basic Survey starts from £150, the Standard Survey from £250 and the Premium Survey from £400, all with VAT included.
Will this cover the whole house?
No. We look closely at the flat roof rather than the whole building. It works alongside a RICS home survey, not instead of one, and structural calculations need a structural engineer.
Does the report include photographs?
Yes. Photographs are taken throughout the survey, and the report uses them to show each finding alongside our recommendations.
Flat roofs in Yiewsley
The wider area around Yiewsley has a long history of building, with Ickenham Hall about 3.3 miles north. 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. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. If your home in Yiewsley 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 an older house near a landmark like St Matthew's, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. If you look after a shop, office or commercial unit, for instance near The Chimes, flat roofs over shops and units are easy to forget until water comes through a ceiling.

How the survey changes by roof type
EPDM rubber
A rubber roof can last 30 to 50 years, provided its details were done well. We look closely at each of those details.
Single-ply membranes
On single-ply roofs, the welds between sheets are the key detail. We look at seams, corners and the joints around outlets and upstands.
What we do, step by step
Where it’s relevant and can be reached safely, the roof space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement. The whole visit typically takes between one and two hours on an ordinary house, and more on a big or complicated roof. In Yiewsley, 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.
- First we go through the roof, what’s beneath it and any problems so far.
- The roof is viewed from safe positions, including the roof itself where that’s safe.
- The covering is checked for wear, splits, blisters and standing water.
- We photograph and record the outlets, upstands, trims and rooflights.
- A written report with photos and recommendations is emailed to you.
Preparing for the visit
- Jot down any questions you want answered
- If it is not your property yet, arrange access through the agent
- Leave side gates unlocked
Book a survey
If you have photos of the roof, send them over. Take them safely from ground level or a window, and please do not climb up for a closer look. To get started, ring 07833 053749 or drop us an email.
