Local flat roofs in Crosspost
Historic houses such as Ockenden Manor, about 3.1 miles north-east, show how far back building in the area around Crosspost goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area. Older houses across Sussex often have handmade clay tiles, and many have tile-hanging on their upper walls. Horsham stone slab roofs survive on some old Sussex buildings. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Anyone responsible for a site like Bolney CofE Primary School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. For landlords with property near Wivelsfield station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

Flat roof surveys for homes and businesses in Crosspost
A flat roof survey looks at the covering, the edges, the outlets and the details where the roof meets walls and rooflights. We cover felt, mastic asphalt, EPDM rubber, GRP fibreglass and single-ply roofs. We survey extension, garage and dormer roofs as well as bigger roofs on flats, offices and units. The findings go into a written report with photos, setting out the defects and what we’d recommend. We survey GRP fibreglass, felt flat roofs and upstands and outlets, and the problems we are asked to look at most are edge trims that have lifted or split and failed seals around rooflight kerbs.
Somewhere as small as Crosspost, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included when you book.
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.

Questions from Crosspost
Is my home in Crosspost listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Is Crosspost in the area you cover?
Yes, Crosspost is within the area we cover. We work right across London and South East England. Just ring 07833 053749 or send us an email and let us know about the property.
Can you inspect my roof with a drone?
Where it helps and it is safe, yes. Whether we can fly on the day depends on the weather and the airspace rules, and we check for restrictions near airports before flying. We hold a CAA Flyer ID and Operator ID.
Do you give a life expectancy for the roof?
There’s no honest way to give an exact number of years. Typical ranges are around 15 to 20 years for felt, 30 to 50 for EPDM and up to about 30 for GRP, but your report describes the actual condition.
Will this cover the whole house?
No. We look closely at the flat roof rather than the whole building. It complements a RICS home survey rather than replacing it, and it is not a structural engineer’s report.
How much is a survey?
Flat roof survey starts from £150, including VAT. The final figure depends on the roof and the package you choose, confirmed before anything is booked.
Do you survey on Saturdays and Sundays?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Let us know your preferred days as you book.

Why it is worth a survey now in Crosspost
A small split in a flat roof is normally a modest job when it’s found early. Left alone, water can soak the insulation and the deck, and the job grows. A survey now shows which you’re dealing with. Outbuildings and barns around Crosspost are easy to forget, but a failed roof there can spoil what’s stored inside. A quick look before winter can save a lot.
We offer three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, with VAT included. The price for your roof depends on its size, access and what you’d like to know.
What you get with us
- Clear package prices, including VAT
- Thermal imaging and drone inspection where they help
- Independent findings on the roof’s condition
- Photographs and a written report every time
What we are asked to look at in Crosspost
Flat roofs take the full force of the weather on a surface that drains slowly. In time, the covering dries out, cracks and loosens at its edges and laps. People normally call us when a leak appears, before a purchase, or when the roof may be near the end of its life.
Most people get in touch when they’ve noticed something like this:
- Blisters and bubbles in the covering
- Blocked or damaged outlets
- A sagging deck under the covering
- Cracked or split membrane
Take an older house close to St Mary Magdalene's Church: flat-roofed rear additions and dormers added over the years are worth checking.

Useful tips for Crosspost property owners
These tips come from what we see on roofs every week, before and after a survey:
- Ask contractors to protect the roof if they work on it
- Clear roof outlets and gutters each autumn
- Keep clear of rooflights and fragile roof sheets
- Check that new brackets or units haven’t damaged the covering
Landlords, owners and managing agents can keep the report as a dated record of the roof. It is useful when planning upkeep and setting budgets, and it makes changes easy to spot at the next survey.
Check the roof from a window after a downpour. Water still lying a day or two later is worth getting looked at.
What we can’t see
It helps to know what a survey won’t do before booking:
- A promise that the roof won’t leak in future
- Structural calculations, which need a structural engineer
- Testing older roof sheets for asbestos
If in doubt, ring 07833 053749 or drop us an email and we’ll point you to the right survey. The full list of what we check.

What happens on the day
You do not need to do much on the day. Show us any stains, drips or problem areas you know about, and we will get on with the inspection. The survey itself takes between one and two hours for a house, and about three to four hours for a commercial roof. Cottages and farmhouses around Crosspost often have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can be seen safely.
- 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.
- You get a photo-illustrated written report and our recommendations.
Getting ready for the survey
- Keep pets inside or away from the areas we’re looking at
- Point out any leaks or damp patches
- If you’re buying, check with the agent that we can get in
