- Raised blisters across the surface

About our flat roof survey in The Chart
Our flat roof survey checks the waterproof covering and every detail around it, from edges and upstands to outlets and rooflights. Felt, asphalt, EPDM, GRP and single-ply PVC or TPO roofs are all part of the work. It suits a small roof over an extension or garage as well as a large one over flats, offices or units. The findings go into a written report with photos, setting out the defects and what we’d recommend. Typical surveys look at cracked or split membrane and loose or cracked edge trims, across GRP fibreglass, EPDM rubber and upstands and outlets.
In a village or hamlet like The Chart, flat roofs are typically on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. We simply plan the journey and access beforehand. Garages and outbuildings are easy to forget, so mention any you want included as you book.
The report does not just list problems. It explains what we found, why it matters and what we recommend, so you can plan your next steps.

Rented homes, blocks and businesses
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work around your tenants.
If the property is let, the agent or a tenant can let us in, at a time agreed in advance. Surveys run on weekdays and at weekends, which helps when tenants work during the week.
Local flat roofs in The Chart
Historic houses such as Chartwell, about 1.9 miles east, show how far back building in the area around The Chart goes. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material. In Surrey, older roofs are often handmade clay tile, with tile-hanging on many upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
Take a building like Limpsfield CofE Infant School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. Take an older house close to St Andrew's: the joins between later flat roofs and the old walls are where problems usually start.
The Chart is about 6 miles south-east of Caterham, in Surrey. The Chart is one of many places we visit across Surrey, for homes and businesses alike. The Chart is one of the towns and villages in Surrey we cover for flat roof surveys. For surveys nearby, see our Crawley page.

Leave it or get it looked at?
Ponding seldom gets better on its own. Most often it means blocked outlets, poor falls or a deck that is dipping, and each wet season wears the covering further. Knowing the cause early gives you more choice over what to do. Outbuildings and barns around The Chart are easy to forget, but a failed roof there can spoil what’s stored inside. It is worth including them in a survey before a winter does the damage.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Flat roof survey starts from £150, including VAT.

The survey, step by step
On the day, we begin with a quick chat about the roof and anything that is worrying you. After that, we check everything we can see safely. Most surveys take roughly 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. Around The Chart, older homes can have small or awkward roof spaces, so it helps to know whether there’s a loft hatch and how easy it is to reach. We only go where it’s safe.
- You let us know about the roof, its covering if you know it, and any leaks.
- We view the roof from the ground, from windows and from the roof where it is safe to do so.
- We check and photograph the covering, the falls, the upstands, the outlets, the trims and any rooflights.
- Inside, we look for damp and staining under the roof where there is access.
- You get a written report with photos and our recommendations.
Before the survey
- Keep pets in another room
- If you’re buying, let the agent know when we are coming
- Point out any leaks or damp patches
Booking a survey
If you have photos of the roof, send them over. Pictures from the ground or a window are fine. To get started, ring 07833 053749 or send us an email.

What a flat roof survey does not cover
Our survey isn’t a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Whether old sheeting or boards contain asbestos
- What’s under the membrane without opening it up
- Parts of the roof that are not safe to walk on or view
If in doubt, phone 07833 053749 or email us and we will point you to the right survey before booking. What our survey covers.
Roofs we survey in The Chart
- Felt flat roofs
- Mastic asphalt
- Upstands and outlets
- GRP fibreglass
- EPDM rubber
- Single-ply membranes
When to book a survey in The Chart
A flat roof lies open to sun, rain and frost, and water drains off it 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.
A survey makes sense if you’ve noticed:
- Leaks around rooflights
- Raised blisters across the surface
- Outlets that hold water back
- Dips that suggest the deck is deflecting
If you own a rental within reach of Hurst Green station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
What to check before booking
- How much experience they have with roofs like yours
- Their drone registration, if they fly one
- What’s outside the scope of the survey
- Whether you get a written report with photos
DIY checks: what’s safe
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way. That part is for a survey, using safe viewpoints and a drone where it applies.
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
FAQs for The Chart
How do I find out if my home in The Chart is listed?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
Do you cover The Chart?
Yes. We survey roofs across London and the South East, and The Chart is part of that. You can ring 07833 053749 or send us an email with the address and a few details, and we will talk through which survey suits.
How much does a flat roof survey cost in The Chart?
Prices start from £150, including VAT. What you pay for your roof depends on its size, height, access and the package.
Will you check the loft?
Yes, where the survey calls for it and there is safe access. We look for staining, damp, daylight and signs of movement.
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.
Which flat roof coverings do you cover?
Felt, asphalt, EPDM, GRP and single-ply roofs are all covered. If you do not know what your roof is, we will identify it on the day.
Do you cover flat roofs on blocks of flats?
Yes. Offices, units, shops and blocks of flats are all part of our work. We quote bigger roofs on their size and how they’re reached, so please phone 07833 053749 or email us with the details.
