What a survey costs
Our packages start from £150, inc. VAT. What you pay for your roof depends on:

We offer three survey packages: Basic from £150, Standard from £250 and Premium from £400, all inc. VAT. The price for your roof depends on its size, access and what you want to find out.

About our flat roof survey in Isleworth
Many commercial buildings and blocks of flats have big 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 phone 07833 053749 or use the contact form with the address and an idea of the roof’s size. Typical surveys look at outlets that hold water back and damaged trims at the roof edge, on felt flat roofs, upstands and outlets and single-ply membranes.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, and each fails in its own way. In Isleworth, as anywhere in London, the right approach depends on what the roof is made of. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
What you get is a clear record of the flat roof on the day we saw it. It is useful straight away, and a good reference for later.

Useful tips for Isleworth property owners
You don’t need to be a roofer to help. Here’s what helps most:
- Have the roof looked at again after a severe storm
- Keep records of when the roof was laid and what work has been done
- Ask contractors to protect the roof if they work on it
- Clear roof outlets and gutters each autumn
Buyers can take the findings back to the seller or the agent. You might ask for work to be done before completion, or discuss the price, depending on the findings.
Clear leaves and silt from outlets and gutters, above all in autumn. Water that can drain away does far less harm than water that sits.
Flat roof surveys around Isleworth
The wider area around Isleworth has a long history of building, with Syon House about 0.9 miles north-east. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first. Isleworth has a number of hotels within about a mile and a half. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
The streets around a church such as Church of All Saints are often among the oldest in a place, and if your home is one of the older ones nearby, flat-roofed rear additions and dormers added over the years are worth checking. If you run a hotel or guest house in or near Isleworth, a roof problem can mean rooms out of use, so it’s worth knowing the roof’s condition.

When to book a survey in Isleworth
No flat roof covering lasts for ever. Felt roofs often last around 15 to 20 years, EPDM often 30 to 50 years and GRP up to about 30, although how well it was laid and looked after matters a great deal. A survey shows how yours is holding up, whatever its age.
These are some of the problems a survey can pick up:
- Loose or cracked edge trims
- Gaps at upstands and abutments
- A sagging deck under the covering
- Blisters and bubbles in the covering
For businesses in and around places like Treaty Centre, the flat roofs over shops and commercial units are worth checking before a leak, not after.
Choosing a roof surveyor
- Their report turnaround times
- What follow-up you get after the report
- How much experience they have with roofs like yours
- Whether they hold professional indemnity and public liability insurance
Can I check my roof myself?
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, which helps when we check the roof.
It’s useful to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us as you book.
Isleworth questions
Can parking be tricky for a visit in Isleworth?
Typically it’s manageable with a little notice. Let us know the parking rules on your street and we’ll work around them.
Is my home in Isleworth listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it is worth checking before planning any.
Will you fly a drone over my roof?
Yes, where it applies and safe. We fly a sub-250g drone and we’re a CAA-registered drone operator (Flyer ID and Operator ID). Drone inspection is part of the Drone Roof Survey and the Premium Survey, where it applies.
Will this cover the whole house?
No. We look closely at the flat roof rather than the whole building. It complements a RICS home survey rather than replacing it, and structural calculations need a structural engineer.
Do you cover flat roofs on blocks of flats?
Yes. We survey flat roofs on commercial buildings as well as homes. Expect about 3 to 4 hours on site for most commercial roofs, with larger roofs quoted on their size.
Do you cover Isleworth for flat roof surveys?
Yes. We survey roofs across London and South East England, Isleworth included.
Can you survey a shared roof?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we are allowed to reach, and the report makes that clear.
What we look for on each type of roof
Mastic asphalt
Without seams, asphalt tends to fail through cracking and at its skirtings. We record any crazing or splits and where water may be getting in.
Felt and built-up roofs
Built-up felt is one of the most common flat roof coverings on extensions, garages and dormers. We look for blistering, cracking, split laps and worn mineral surfacing.
The survey, step by step
The visit usually starts outside and finishes in the loft: outside views come first, then the roof space if there is safe access. All told, expect an hour or two for a small flat roof at home, and longer for a large commercial one. In a London area like Isleworth, the main things to sort out are parking and access: let us know about parking, the floor the property is on, any shared entrance and loft access. On the day, the roof is looked at from ground level, from windows, from inside the roof space and from the roof where it’s safe.
- 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’s access.
- We view the roof from safe positions and never walk on fragile surfaces.
- Each defect is photographed and its likely cause noted.
- The report explains the condition and recommends what to do first.
Getting ready for the survey
- If you are buying, let the agent know when we’re coming
- Unlock side gates and any roof access doors
- Let us know about parking before the day
How to book
Booking is simple: just ring 07833 053749 or drop us an email, let us know about the property and we’ll suggest the right survey. We confirm the price before anything is booked.
