Crabtree Flat Roof Survey

About our flat roof survey in Crabtree
Our Basic Survey, from £150, gives you a visual inspection with photos and written recommendations. For moisture detection and a structural check, the Standard Survey starts from £250. Moisture readings are useful on flat roofs, where water can spread under the covering before it shows inside. Bigger commercial roofs are priced on their size and access. Common reasons to book are outlets that hold water back and loose or cracked edge trims, on mastic asphalt, single-ply membranes and felt flat roofs.
Somewhere as small as Crabtree, 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. We simply plan the journey and access in advance. If there are outbuildings or garages with flat roofs, mention them as you book.
You receive the findings by email, ready to forward to whoever needs them. Turnaround is within 48 hours for Basic, 24–48 hours for Standard and same day for Premium.

Crabtree questions
Will you come out to Crabtree?
Yes. Crabtree is within the area we cover, which takes in towns, villages and rural addresses. We work right across London and the South East. Just mention lanes, gates or anything else about the route as you book.
Do you cover Crabtree?
Yes, Crabtree is within the area we cover. We cover the whole of London and South East England. Just ring 07833 053749 or drop us an email and let us know about the property.
Is ponding on a flat roof a problem?
Water that lies on a flat roof for days is a sign that something needs attention. The cause may be the outlets, the falls or the deck. The survey looks at each and records the likely cause.
Will you walk on the flat roof?
Only where it’s safe to do so. If not, we use safe viewpoints and look inside, and we note any area we couldn’t see. Fragile surfaces are never walked on.
Can you find where water is getting through my flat roof?
We check the whole roof, since water can travel before it shows inside. Every split, lap, upstand, outlet and rooflight we can see is looked at. Where nothing visible explains the leak, the report says what to try next.
Can you survey a flat roof on an office or unit?
Yes. We survey flat roofs on commercial buildings as well as homes. Expect about 3 to 4 hours on site for most commercial roofs, and larger roofs are quoted for their size.
What types of flat roof do you survey?
We survey felt and built-up roofs, mastic asphalt, EPDM rubber, GRP fibreglass and single-ply PVC and TPO. Not sure what yours is? We will tell you in the report.
When you need someone else
Without opening up the roof, some things stay hidden, and that sets some limits:
- Whether old sheeting or boards contain asbestos
- Fragile surfaces, which we don’t walk on
- An exact number of years the roof has left
Not sure which survey suits your roof? You can phone 07833 053749 or send us an email and we’ll tell you before booking. The full list of what we check.

Surveys for landlords and agents in Crabtree
Shared roofs need a little more planning: we need access agreed with whoever owns or manages the building. Mention it when you get in touch and we will plan the visit with that in mind.
If the property is let, the agent or a tenant can let us in. Surveys run on weekdays and at weekends, which can make access easier.
Flat roofs in Crabtree
Tyes Place, about 4.3 miles north-east, is one of the historic houses in the wider area around Crabtree. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. 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 fill the gaps in between, on extensions, garages, dormers and business premises.
If you live in an older home near Old Church House the Glebe, the joins between later flat roofs and the old walls are where problems usually start. Take a building like Newells Preparatory School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Crabtree is about 5 miles south-east of Horsham, in West Sussex. Houses, flats, blocks and commercial buildings in Crabtree can all book flat roof surveys, with a written report and photographs every time. Our West Sussex coverage includes Crabtree. For surveys nearby, see our Crawley page.
Surveys in RH13 work the same way as everywhere else we cover. If you need a flat roof survey at a property on Mill Lane, Peppersgate and Long Hill or a nearby road, we can survey it. We also cover the places around Crabtree: Lower Beeding (1 mile north), Colwood (1 mile south-east), Monk's Gate (2 miles north-west), Plummers Plain (2 miles north-east) and Mannings Heath (2 miles north-west). We also work in nearby towns like Crawley (7 miles north-east), Horsham (5 miles north-west), Worthing (14 miles south-west), Haywards Heath (7 miles east), Burgess Hill (7 miles south-east) and East Grinstead (13 miles north-east).
Landmarks near Crabtree
Typical jobs here are in homes near Leonardslee and the streets around them. For rail, the closest station is Horsham station, about 4.6 miles north-west of the centre. Nearby you’ll also find Horsham Hospital (4.9 miles north-west). Not far away are Knepp Wildland.
When to book a survey in Crabtree
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. Most people book a survey after a leak, before buying, or when they think the roof is getting old.
Typical things we’re asked to look at include:
- Raised blisters across the surface
- Damaged trims at the roof edge
- Leaks around rooflights
- Gaps at upstands and abutments
If you own a rental within reach of Horsham station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Before you book anyone
- Which viewpoints they use to see the roof
- What follow-up you get after the report
- Will they check the loft as well as the outside?
- How long they’ve been surveying roofs
The survey, step by step
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes an hour or two for a small flat roof at home, and longer for a large commercial one. If you have questions on the day, just ask. Older rural homes like those around Crabtree can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints.
- We start with the details: the address, the roof’s use and any leaks or stains.
- The roof is inspected from safe viewpoints, and from the roof itself where that’s safe.
- Every part of the roof we can see is looked at: covering, falls, upstands, outlets, trims and rooflights.
- We check the rooms or spaces under the roof for staining where we can reach them.
- The findings are written up with photos and recommendations and emailed to you.
Before the survey
- Keep pets in another room
- Gather any invoices or paperwork from past roof work
- If the roof is shared, arrange access with whoever manages the building

Advice
How we price flat roof surveys
A few things affect what a survey costs:
- How big the roof is
- Extensions, dormers and garages with roofs of their own
- Height and safe access
- Features like valleys, chimneys, dormers and parapets
The Premium Survey includes thermal imaging and drone inspection where applicable, which starts from £400, with VAT included. We can help you choose the package that fits what you want to find out.
What to tell us when you get in touch
Before you get in touch, it’s useful to have:
- Your timetable, such as an exchange date
- The type of building and roof, such as pitched or flat
- The property’s address and postcode
- Photos of the roof, taken safely from ground level or a window
If you are buying, it is useful to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply ring 07833 053749 or use the contact form whenever suits you.
Why act early in Crabtree
Before replacing a flat roof, it’s useful to know if you really need to. Sometimes some details are to blame, and sometimes the covering has simply had its day. The report sets out what we found, so you can make that decision with a roofer. Matching old materials, such as handmade tiles or stone slates, can take time to source. That is one more reason to find defects before they become urgent.
We offer three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, all including VAT. The price for your roof depends on its size, access and what you’d like to know.
