Flat roof survey in Hanworth: what you get
Ponding is frequently the first sign that something on a flat roof isn’t right. It can point to poor falls, a blocked outlet or a deck that is deflecting. The survey notes any ponding, the state of each outlet and any dips that hint at a sagging deck. If the deck itself looks like a structural concern, we will recommend a structural engineer. Typical surveys look at blisters and bubbles in the covering and standing water left after rain, across GRP fibreglass, felt flat roofs and single-ply membranes.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, and each fails in its own way. Which one is on a roof in Hanworth shapes how it’s checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
Pictures do a lot of the work in our reports, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

Leave it or get it looked at?
For a buyer, the best time to learn about a flat roof is before contracts are exchanged. After that, the cost of any work is yours. A report gives you facts to put to the seller or agent. In a London terrace or conversion, a roof defect rarely stays your problem alone: failed flashings and blocked valley gutters can send water into more than one home. Finding it early keeps the work smaller.
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package matters as well. The price is always agreed first.

What we do, step by step
Where it’s relevant and can be reached safely, the loft space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. The whole visit usually takes roughly 1–2 hours at a typical home, though large, tall or awkward roofs take more time. In a London conversion, the way into the loft space is often from a communal landing or the top flat. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- We start with the details: the address, the roof’s use and any leaks or stains.
- We view the roof from the ground, from windows and from the roof where it’s safe to do so.
- We check and photograph the covering, the falls, the upstands, the outlets, the trims and any rooflights.
- We check the rooms or spaces under the roof for staining where we can reach them.
- The findings are written up with photos and recommendations and emailed to you.
Preparing for the visit
- Mention any parking restrictions on your street
- Leave a clear route to the loft
- Show us where any leaks or stains appear
Getting a price
Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. For any other survey, just ring 07833 053749 or send us an email when you are ready.
Advice
Hanworth: your questions answered
Can parking be tricky for a visit in Hanworth?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Do you carry out roof surveys in Hanworth?
Yes. Our area covers London and the South East, and Hanworth is part of that. Just ring 07833 053749 or send us an email and let us know about the property, and we’ll talk through which survey suits.
Will you fly a drone over my roof?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
How long does the survey take?
It normally takes about one to two hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. The report follows by email.
Can you give me structural calculations?
No. Visible signs like deflection or sagging are recorded, but we do not provide calculations or an engineer’s opinion. The report will say if you need an engineer.
Will you check the loft?
If there’s a loft and safe access to it, yes. From inside, the underside of the roof often shows damp, staining or daylight that can’t be seen from outside.
What does a roof survey cost?
Our price is from £150, including VAT. The final figure depends on the roof and the package you choose, and it is agreed before booking.

How the survey changes by roof type
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.
Rooflights and upstands
Rooflights and fragile sheets are never walked on. We view them from safe positions and photograph what we see.
Flat roof surveys around Hanworth
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. If your home in Hanworth 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. About 2 miles east lies Strawberry Hill House, a reminder of how long the area around Hanworth has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area.
For businesses in and around places such as Treaty Centre, outlets and upstands on commercial flat roofs are the places to check before trouble starts. If you look after a building such as Buckingham Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. If you let a flat or house near Hampton station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
