Flat roof surveys for homes and businesses in Hounslow West
A flat roof doesn’t shed water the way a pitched roof does. Water lies on the surface for longer, so a small split or a blocked outlet can soon lead to a leak. The surface, the falls, the upstands and the trims are all looked at closely, and we note any sign that the deck below has got wet. That way, defects are found before they reach the room below. Typical surveys look at cracked or split membrane and blisters and bubbles in the covering, on mastic asphalt, single-ply membranes and felt flat roofs.
Commercial and residential blocks across London frequently have big flat roofs with plant, rooflights and access walkways. Every penetration and upstand is a place where a membrane can fail. In Hounslow West, 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.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

What we look for on each type of roof
Mastic asphalt
With age, asphalt can harden and crack with movement. We note where this is happening and how widespread it looks.
Felt and built-up roofs
Many extensions, garages and dormers have a felt roof laid in layers. The survey checks for blisters, cracks, open laps and bare patches where the surfacing has worn.

Hounslow West questions
How do I find out if my home in Hounslow West is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
Do you cover commercial flat roofs around Hounslow West?
Yes, commercial buildings, hotels included, are part of the work. Access to the roof is sorted out with whoever manages the building before the day.
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.
I live in a flat. Can you survey the roof?
Yes, as long as access is agreed. Roofs over flats are often shared, so the freeholder or managing agent needs to agree access. We inspect only the parts we are allowed to reach.
Is this a RICS survey?
No. This is a survey of the roof only, so it is not a RICS Level 2 or Level 3 survey. Many buyers have both.
How long will you be at the property?
It typically takes about 1–2 hours at a typical home, and longer for a large or complex roof. We will confirm the timing when you book.
What does a roof survey cost?
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 including VAT.
Rented homes, blocks and businesses
Surveys can also be booked by buyers’ agents acting for a client. The report is emailed, so it can go straight to your client.
Landlords and letting agents in Hounslow West book surveys as well as householders. The report gives you a dated record of the flat roof, with photographs, which helps you plan work between tenancies.
Why get it checked now?
Standing water on a flat roof rarely sorts itself out. Most often it means blocked outlets, poor falls or a deck that is dipping, and each wet season wears the covering further. Knowing the cause early gives you more choice over what to do. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. That’s a good reason to find problems early, while there’s time to plan.
All our prices include VAT. Our price is from £150, including VAT. You will know the exact price before booking.

The survey, step by step
The aim of the visit is simple: to look at the flat roof as closely as is safe and record what we find. Notes and photos go into the written report. The visit normally takes roughly 1–2 hours for a small flat roof at home, and longer for a large commercial one. For a visit in Hounslow West, parking and access are the things to plan: let us know about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at what can be seen safely from the ground, windows, the loft and, where it is safe, the roof itself.
- You tell us about the roof, its covering if you know it, and any leaks.
- We look at the roof from wherever it can safely be seen.
- Every part of the roof we can see is looked at: covering, falls, upstands, outlets, trims and rooflights.
- Where there’s safe access, we look at the ceilings and spaces below for signs of water.
- The findings are written up with photographs and recommendations and emailed to you.
Getting ready for the survey
- If you’re buying, check with the agent that we can get in
- Have keys ready for side gates, garages or roof access doors
- Keep pets in another room

Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, ring 07833 053749 or use the contact form.
