How a flat roof survey works in Portsea
Buying a home with a flat-roofed extension, dormer or garage? It’s useful to know that roof’s condition before you exchange. Many felt roofs need renewing after around 15 to 20 years, and EPDM and GRP often go on for longer. We set out the type of covering, its condition and the defects we found, with photographs of each. You then have something specific to put to the seller or agent. We are often asked to look into failed upstands where the roof meets a wall and loose or cracked edge trims, on EPDM rubber, mastic asphalt and upstands and outlets.
In a smaller place like Portsea, some flat roofs sit in the open, so wind catches loose edges and trims. Felt and bitumen also age in strong sun. Splits, blisters and lifting edges are what to look out for. Standing water that lingers for days after rain is another sign worth watching for.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

How the survey changes by roof type
GRP fibreglass
A GRP fibreglass roof is a hard, resin-bonded surface over a timber deck. The survey checks for cracking at board joints, at the edge trims and where the roof meets walls.
Rooflights and upstands
Upstands at walls and parapets need to stay watertight as the building moves. We look for splits, gaps and failed flashings over the top.
When to book a survey in Portsea
Flat roofs take the full force of the weather on a surface that drains slowly. Over the years, coverings harden, crack and start to come away at the edges. People usually call us when a leak appears, before a purchase, or when the roof may be near the end of its life.
Problems we come across often include:
- Pools of water lying on the roof
- Failed seals around rooflight kerbs
- Blocked or damaged outlets
- Cracked or split membrane
For an older house near a landmark such as St Ann's Church, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
Choosing a roof surveyor
- How soon the report will arrive
- Whether the price includes VAT
- What exactly goes into their report
- Their drone registration, if they fly one
What happens if roof problems are left?
Flat roofs cannot normally be seen from the street, so they’re often overlooked. Many owners only find out a roof is worn out when water comes through. A survey every few years stops that from catching you out. On a bungalow or cottage around Portsea, the roof sits close to the rooms below, so a small leak can mark a ceiling within a few storms. Catching the cause first saves redecorating as well.
Our price is from £150, including VAT. The final price depends on how big and how high the roof is, how it can safely be seen and the package you choose.
Why book us in Portsea
- Thermal imaging and drones used where they help
- An independent look at the roof
- A sub-250g drone, flown with a CAA Flyer ID and Operator ID
- Professional indemnity and public liability insurance

Can I check my roof myself?
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date.
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.

Local flat roofs in Portsea
Portsea lies within about 1 mile of the sea, and being near the sea means more wind and salt than a roof inland would face. On a flat roof near the sea, edge trims and upstands take the brunt of the wind, and metal parts corrode faster. Thatch survives on some older buildings in Hampshire’s villages. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
Landlords with a home close to Portsmouth Harbour station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies. Hotels and guest houses near Portsea can’t easily close rooms for a leak, so it’s worth knowing the roof’s condition.
Portsea is about 1 mile south-west of Portsmouth, in Portsmouth. Portsea gets the same service as everywhere else we work: a careful look at whatever is safely visible, photos and a clear written report. Portsea is one of the towns and villages in Portsmouth we cover for flat roof surveys.
Flat roof surveys in PO1, PO12 and PO5 are booked the same way as anywhere else. That includes homes and businesses on Main Road, Park Road and Scott Road. Nearby, we also carry out flat roof surveys in Portsmouth Point (1 mile south), Clayhall (2 miles south-west), Haslar (2 miles south-west), Alverstoke (2 miles south-west) and Privett (2 miles west).

Near you in Portsea
Around Portsea, our work takes us to homes and buildings near The Ship & Castle pub, St Jude's CofE Primary School and Charter Academy and the streets around them.

How it works
There isn’t much for you to do on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we’ll take it from there. The survey itself takes an hour or two for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. A visit to a smaller place like Portsea is no different on the day: outside, inside and from any safe vantage point, in that order. Point out any stains, cracks or loose pieces you’ve spotted.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- Inside, we look for signs of water under the roof where we can reach.
- The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
- We record every defect with a photo and its likely cause.
- The report explains the condition and recommends what to do first.
Before we arrive
- Clear the way to the loft hatch
- Mention any parking restrictions on your street
- Unlock side gates and any roof access doors

Questions from Portsea
Is my home in Portsea listed or in a conservation area?
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.
Is Portsea within the area you cover?
Yes, Portsea is on our map. Villages and rural addresses get the same survey as a town house.
Should I worry about standing water on my flat roof?
Standing water a day or two after rain normally needs attention. It could be the outlets, the falls or a deflecting deck. The survey looks at each and records the likely cause.
How soon will I get the report?
Report times are set by the package. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. If you have a deadline, like an exchange date, tell us as you book.
Can you survey at the weekend?
We carry out surveys on weekdays, Saturdays and Sundays. To arrange a date, call 07833 053749 or drop us an email.
How much does a flat roof survey cost in Portsea?
Our price is from £150, including VAT. What you pay for your roof depends on its size, height, access and the package, and it’s agreed before booking.
How experienced are you?
We have completed more than 5,000 surveys, across 20+ years of surveying roofs.
Honest limits
Without opening up the roof, some things stay hidden, and that sets some limits:
- Asbestos testing, which needs a specialist asbestos surveyor
- What’s under the membrane without opening it up
- An exact number of years the roof has left
