Not sure what state the flat roof is in? You can book a flat roof survey in Thorney Island and across West Sussex.
- Upstands pulling away from walls
- Blocked or damaged outlets
- Pools of water lying on the roof
Practical tips
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Clear roof outlets and gutters each autumn
- Book a survey every few years
- Limit foot traffic on the covering
- Check from a window for ponding after heavy rain
Landlords, owners and managing agents can keep the report as a dated record of the roof. It’s useful when planning upkeep and setting budgets, and it gives a baseline to compare against next time.
Keep outlets, gutters and hoppers clear, especially after the leaves fall. A flat roof that drains well wears much more slowly.
Flat roof survey in Thorney Island: what you get
Each type of flat roof has its own weak points. Built-up felt tends to blister and crack, asphalt crazes and splits, EPDM can lift at its laps, and GRP can crack at board joints and edge trims. On PVC and TPO single-ply roofs, we look closely at the welded laps, edges and fixings. Once you know the covering and its condition, planning the next step is far easier. If you’ve noticed blisters and bubbles in the covering and outlets choked with leaves and silt, we can find out what’s behind it, on EPDM rubber, mastic asphalt and GRP fibreglass alike.
Flat roofs on exposed homes in small places like Thorney Island take more wind and rain, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, normally show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are normally the first part of a flat roof to go.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

Roof by roof
Mastic asphalt
With age, asphalt can harden and crack with movement. We note where this is happening and how widespread it looks.
Single-ply membranes
Plant, fixings and foot traffic can all damage a single-ply roof. We note any punctures, tears and loose areas we can see.
FAQs for Thorney Island
How do I find out if my home in Thorney Island is listed?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Will you come out to Thorney Island?
We do. Villages and rural addresses get the same survey as a town house.
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 water that sits wears the covering sooner. Our survey notes the ponding and what seems to be causing it.
Do I have to be there for the survey?
Not always. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
How do you inspect a flat roof?
We inspect from wherever is safe: the roof itself where that’s safe, plus windows, vantage points and the rooms below. Fragile rooflights and fragile sheets are never walked on.
Does the weather affect the survey?
Light rain doesn’t usually stop a survey. Strong wind or heavy rain can stop drone flights and make roof access unsafe, so if conditions aren’t right we will arrange another day with you.
What do I do with the report?
The report arrives by email. With Standard there’s a follow-up consultation; with Premium, an in-person consultation, so you can talk the findings through.

Why it’s worth a survey now in Thorney Island
Waiting for a stain inside means the water has already got through the layers. A survey can find worn areas and failing details before that point, while there’s still time to plan the work. For older village homes like those around Thorney Island, the right replacement materials aren’t always easy to find quickly. That is one more reason to find defects before they become urgent.
Flat roof survey starts from £150, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, including VAT, and we can help you choose.

Flat roofs in Thorney Island
The coast is about 1 mile or less from Thorney Island, where sea air brings more salt and stronger wind than inland. On a flat roof near the sea, edge trims and upstands take the brunt of the wind, and metal parts corrode faster. Older houses across Sussex frequently have handmade clay tiles, and many have tile-hanging on their upper walls. A few old Sussex buildings still carry heavy Horsham stone slabs. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Warblington Castle lies about 2.1 miles north-west, so building around Thorney Island goes back a long way. Older homes nearby may have later flat-roofed extensions or dormers, often re-covered more than once. For an older house near a landmark like The Parish Church of St Nicholas, the flat roofs on later extensions tend to wear out long before the main roof. If you look after a building like Thorney Island Community Primary School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.

Rented homes, blocks and businesses
Shared roofs need a little more planning: we need access agreed with the freeholder or managing agent. Mention it when you get in touch and we will plan the visit with that in mind.
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out by urgency where it matters, which helps with budgets and planning.
What you can safely check yourself
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it.
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way. That is where a survey comes in.
What we do, step by step
There isn’t much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we will get on with the inspection. A typical survey takes between one and two hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. Cottages and farmhouses around Thorney Island often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints.
- 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 is safe.
- We check the covering for splits, blisters, ponding and wear.
- Upstands, outlets, edge trims and rooflights are checked and photographed.
- The report, with photos and recommendations, comes to you by email.
Getting ready for the survey
- Make a note of anything you’d like us to look at
- If it isn’t your property yet, arrange access through the agent
- Dig out any old roof reports or invoices
