Flat roof survey in Cox Green
Standing water is one of the first things we look for on a flat roof. It can mean the falls were never right, an outlet is blocked or the deck has started to sag. The survey notes any ponding, the state of each outlet and any dips that hint at a sagging deck. Where the deck may be a structural issue, our report says a structural engineer should look at it. We survey upstands and outlets, felt flat roofs and mastic asphalt, and people most often book us about splits and cracks in the covering and dips that suggest the deck is deflecting.
In smaller places like Cox Green, flat roofs are mostly on extensions, garages, porches and dormers. Even a small flat roof can let a good many water into the room below. Knowing the covering and how it was laid tells you what to expect from it. Ponding, splits and lifting edges are the signs to look for from a window.
Where we can’t see part of the flat roof, the report says so. You’ll know exactly what was inspected and what wasn’t.

How the survey changes by roof type
Rooflights and upstands
The joins around rooflights and at upstands are common leak points. We look at how the covering is finished around each rooflight and upstand.
Felt and built-up roofs
Built-up felt is one of the most common flat roof coverings on extensions, garages and dormers. The survey checks for blisters, cracks, open laps and bare patches where the surfacing has worn.

Why it’s worth a survey now in Cox Green
Most flat roofs are out of sight, so they’re easy to forget. Many owners only find out a roof is worn out when water comes through. Regular surveys mean it won’t come as a surprise. Around Cox Green, a leak in an older house can soak into timbers and plaster, which is far harder to put right than the roof fault itself.
Prices start from £150, including VAT. The final price depends on how big and how high the roof is, how it can safely be seen and which survey you book.

Common roof problems in Cox Green
Water that doesn’t drain sits on the roof and speeds up wear. Blocked outlets, poor falls and a sagging deck are the usual causes. Where trees are close by, leaves and silt can block an outlet within a single autumn.
We’re frequently asked to look at:
- Cracked or split membrane
- Ponding water that doesn’t drain away
- Dips that suggest the deck is deflecting
- Outlets that hold water back
The streets around a church such as All Saints' Church are often among the oldest in a place, and if you own one of the older houses nearby, the flat roofs on later extensions tend to wear out long before the main roof.
What to check before booking
- What exactly goes into their report
- Whether they hold professional indemnity and public liability insurance
- What the survey won’t cover
- Which viewpoints they use to see the roof
Before and after the survey
A little preparation and a few simple habits help, both for the survey and for the roof itself. Our tips:
- Keep outlets clear of leaves and moss
- Ask contractors to protect the roof if they work on it
- Note where water lies after a downpour
- Treat rooflights and old sheeting as fragile
The report is emailed to you, ready to share with a roofer, the seller or a managing agent. It is written in plain English, with a photo of each defect, so others can follow it without going up to look.
Small defects are simpler to deal with while they’re still small. A flat roof that’s looked after between surveys normally lasts longer.
Questions from Cox Green
Does a conservation area affect roof work in Cox Green?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Is Cox Green in the area you cover?
Yes. We survey roofs across London and the South East, and Cox Green is part of that. Just phone 07833 053749 or email us and let us know about the property.
Is a flat roof survey the same as a building survey?
No. Our survey covers the flat roof only. It is not a RICS Level 2 or 3 survey of the whole building, and it isn’t a structural engineer’s report. It often sits alongside a buyer’s building survey.
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.
How do I arrange a flat roof survey in Cox Green?
It’s easiest to call 07833 053749 or email us. Let us know the address and a little about the roof, and we will take it from there. Surveys run on any day of the week.
Do you need to get into the loft?
Typically, if there is one and it can be reached safely. From inside, the underside of the roof frequently shows damp, staining or daylight that can’t be seen from outside.
What types of flat roof do you survey?
We cover the main flat roof coverings: felt, asphalt, EPDM, GRP and single-ply. The report names the covering and explains its condition.
Honest limits
In fairness, a roof survey has limits:
- Hidden layers beneath the covering
- Parts of the roof that aren’t safe to walk on or view
- Whether the deck or joists are strong enough
If you’re not sure which survey you need, ring 07833 053749 or email us and we’ll give you a straight answer before booking. What a survey covers and does not.
