FAQs for Picketts Lock
Will parking be an issue for a roof survey in Picketts Lock?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
How do I find out if my home in Picketts Lock is listed?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
What does ponding on a flat roof mean?
Standing water on a flat roof deserves a closer look. It often means a blocked outlet, poor falls or a dipping deck, and it wears the covering faster. Our survey notes the ponding and what seems to be causing it.
Which days do you carry out surveys?
Surveys can be booked for any day of the week: weekdays, Saturdays and Sundays. Just let us know the days that suit you.
Can you give me structural calculations?
No. Our survey is not a structural engineer’s report. If we see signs that need an engineer’s opinion, we’ll recommend one.
How long does the survey take?
Expect it to take about 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. You will then get the report by email, on the timescale of your package.
What’s the best way to book?
It’s easiest to ring 07833 053749 or email us. Let us know the address and a little about the roof. Surveys run on weekdays, Saturdays and Sundays.
Flat roof survey in Picketts Lock: what you get
Ponding is often the first sign that something on a flat roof is not 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. Where the deck may be a structural issue, our report says a structural engineer should look at it. If you’ve noticed gaps at upstands and abutments and outlets choked with leaves and silt, we can find out what’s behind it.
On a London roof terrace or a flat roof over a back addition, water frequently runs under the covering before it shows. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a converted house in Picketts Lock, the roof above may belong to the building rather than one flat.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

Signs you need a flat roof survey in Picketts Lock
Many flat roof problems start at the details rather than the main surface. Upstands, trims, outlets and rooflight kerbs each move and weather in their own way. Where they weren’t finished well, they tend to fail before anything else.
It is worth booking a survey if you’ve seen:
- Blocked or damaged outlets
- Water getting in at rooflights
- Gaps at upstands and abutments
- Splits, cracks and crazing
The streets around a church such as All Saints' Church are frequently among the oldest in a place, and if you own one of the older houses nearby, flat-roofed rear additions and dormers added over the years are worth checking.
Choosing a roof surveyor
- Whether the roof space is looked at, where there is one
- What exactly goes into their report
- Whether they hold professional indemnity and public liability insurance
- Their drone registration, if they fly one
Tips that help
Small things make a difference, both for the survey and for the roof itself. Our tips:
- Note the date and type of any roof work
- Ask contractors to protect the roof if they work on it
- Keep clear of rooflights and fragile roof sheets
- Make sure new fixings through the roof are properly sealed
If you’re buying, the report gives you something specific to take back to the seller or agent. You might ask for work to be done before completion, or discuss the price, depending on what we found.
Small defects are simpler to deal with while they’re still small. A flat roof that is looked after between surveys normally lasts longer.
What happens on the day
The aim of the visit is simple: to see as much of the flat roof as can be seen safely and record it clearly. Notes and photos go into the written report. The visit normally takes between one and two hours for most houses, and longer for a large or complex roof. In Picketts Lock, as in much of London, a good many properties are flats or terraces without side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents when you book.
- First you give us the address, what the roof covers and any leaks you’ve noticed.
- 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.
- Where there is safe access, we check the ceilings and spaces below for signs of water.
- The findings are written up with photographs and recommendations and emailed to you.
Before the survey
- Leave side gates unlocked
- Have any questions written down, so nothing gets missed
- Note where any stains or damp appear
