Booking your survey
There is no need for technical words. It’s enough to let us know:
- Where water is showing inside, if it is
- When you need the report by
- Photos of the roof, taken safely from ground level or a window
- Your postcode, so we can check access and travel
Photos help, if you have them. Take them safely from the ground or a window; never climb up to get a better view. To get started, call 07833 053749 or send us an email.
About our flat roof survey in Halnaker
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. We record the condition with photos so work can be planned and budgeted. We quote commercial roofs on their size and how they’re reached, so please phone 07833 053749 or send us an email with the address and an idea of the roof’s size. If you’ve noticed standing water left after rain and blisters and bubbles in the covering, a survey will tell you what’s going on, whatever the roof.
Flat roofs on exposed homes in small places like Halnaker take more wind and rain, which is hard on edges, upstands and joins in the covering. Felt roofs, which frequently last around 15–20 years, usually show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are typically the first part of a flat roof to go.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

Checking the roof from ground level
Keep a simple record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry.
A DIY look is useful, but it isn’t a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight.
Halnaker: your questions answered
Is Halnaker within the area you cover?
We do. A small place gets exactly the same survey as a big one, with the route planned beforehand.
How do I find out if my home in Halnaker is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
What does ponding on a flat roof mean?
Ponding is worth looking into. It can point to blocked outlets, poor falls or a deck that is sagging, and it wears the covering faster. We record where it sits and the likely cause.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years, across London and South East England.
Will you fly a drone over my roof?
Where it helps and it’s safe, yes. Flights depend on the weather on the day and airspace rules, including flight restriction zones near airports. We hold a CAA Flyer ID and Operator ID.
How long will you be at the property?
Expect it to take an hour or two for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. You’ll then get the report by email.
What happens next?
We email you the written report with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Flat and commercial roofs around Halnaker
Goodwood House, about 1.4 miles west, is one of the historic houses in the wider area around Halnaker. Older homes in the wider area frequently have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first. In Sussex, older roofs are often handmade clay tile, frequently with tile-hanging on the walls below. Horsham stone slab roofs survive on some old Sussex buildings. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops.
Landlords with a home close to Chichester station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round. If you live in an older home near The Priory Church of St Mary and St Blaize, flat-roofed rear additions and dormers added over the years are worth checking.
Halnaker is about 3 miles north-east of Chichester, in West Sussex. If you are in Halnaker, booking works exactly as it does anywhere else: get in touch, agree the price and pick a day. Our West Sussex coverage includes Halnaker and the places around it. There is also a page for Portsmouth.

How the survey changes by roof type
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.
Rooflights and upstands
Rooflights, lanterns and upstands are where many flat roof leaks begin. We check the seals and the covering around each one.
What happens on the day
Safety comes first on every visit. Everything that can safely be seen is inspected, and if part of the roof cannot be seen, the report says so. The survey typically takes about 1–2 hours at most homes, and longer for a large or complex roof. Around Halnaker, older homes can have small or awkward roof spaces, so tell us about the loft hatch and any ladder. We only go where it is safe.
- We agree the roof to be surveyed, its use and any leaks you know about.
- 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.
- Upstands, outlets, edge trims and rooflights are checked and photographed.
- The report, with photos and recommendations, comes to you by email.
Preparing for the visit
- Mention any parking restrictions on your street
- Have keys ready for side gates, garages or roof access doors
- Make a note of anything you’d like us to look at

Signs you need a flat roof survey in Halnaker
A buyer’s general survey frequently recommends a closer look at a flat roof. Owners and managing agents use a survey to plan upkeep, or ahead of a sale or a new lease. Either way, you get a clear record of the roof, with photographs.
It is worth booking a survey if you’ve seen:
- Cracked or split membrane
- Edge trims that have lifted or split
- Blisters and bubbles in the covering
- Water getting in at rooflights
Anyone responsible for a site like Boxgrove CofE Primary School will know that a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.
Before booking any roof surveyor
- Whether any drone flown is registered with the CAA
- Is there a chance to talk the report through?
- How long the report takes to arrive
- What exactly goes into their report
Leave it or get it looked at?
Ponding seldom gets better on its own. Most frequently it means blocked outlets, poor falls or a deck that is dipping, and each wet season wears the covering further. Finding the cause now keeps more options open. In a place like Halnaker, a barn or garage roof left to fail puts whatever is inside at risk. A quick look before winter can save a lot.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before booking.
