How a flat roof survey works in Charndon
Every flat roof covering tends to fail in its own way. Felt can blister and crack, asphalt can craze and split, EPDM seams and laps can lift, and GRP can crack where boards meet or at the trims. On PVC and TPO single-ply roofs, we look closely at the welded laps, edges and fixings. Knowing what you have and how it’s doing helps you plan what comes next. If you are worried about failed seals around rooflight kerbs and damaged trims at the roof edge, we can find out what’s behind it, whatever the roof.
In a village or hamlet like Charndon, flat roofs are typically on extensions, garages, outbuildings or barn conversions. 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 beforehand. Garages and outbuildings are easy to forget, so mention any you want included as you book.
It isn’t only a list of defects. It explains what we found, why it matters and what we recommend, so you can plan your next steps.

Charndon questions
Do you cover Charndon?
Yes, Charndon is one of the places we work. The survey and report are the same in Charndon as anywhere else, and visits run on weekdays and weekends.
Is my home in Charndon listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
Can you tell me how long my flat roof will last?
We do not put a figure on it. As a guide, felt frequently lasts around 15 to 20 years, EPDM frequently 30 to 50 and GRP up to about 30, but your report describes the actual condition.
Do you survey commercial flat roofs?
Yes. Commercial and residential flat roofs are both covered. A commercial roof usually takes about 3 to 4 hours on site, longer if it is large or complex, with larger roofs quoted on their size.
Do you look for flat roof leaks?
Our survey looks across the whole roof, not only above the stain. Splits, open laps, upstands, outlets and rooflights are all checked. Where nothing visible explains the leak, the report says what to try next.
Should I worry about standing water on my flat roof?
Ponding is worth looking into. It can point to blocked outlets, poor falls or a deck that is sagging, and water that sits wears the covering sooner. We record where it sits and the likely cause.
Does someone need to be in?
If the survey includes the loft or the inside of the building, someone needs to let us in. We’ll talk about access as you book.
What we are asked to look at in Charndon
People go onto flat roofs for all sorts of reasons: cleaning windows, fitting aerials or air conditioning, or clearing gutters. A covering that wasn’t designed for foot traffic can crack or puncture. New brackets and fixings through the roof are another common source of leaks.
Typical things we’re asked to look at include:
- Failed upstands where the roof meets a wall
- Edge trims that have lifted or split
- Cracked or split membrane
- Standing water left after rain
The streets around a church such as Church of St Michael are frequently among the oldest in a place, and if your home is one of the older ones nearby, the flat roofs on later extensions tend to wear out long before the main roof.
What to check before booking
- What happens after the report arrives
- Whether the inside of the roof is included
- Which limits apply to the survey
- Whether VAT is in the quoted price
What this survey cannot tell you
To be straight with you, there are limits to any roof survey:
- An exact number of years the roof has left
- Whether the deck or joists are strong enough
- Asbestos testing, which needs a specialist asbestos surveyor

Flat roof surveys around Charndon
Older buildings in west Oxfordshire frequently have Cotswold stone slate roofs, and some Oxfordshire villages still have thatch. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. Claydon House, about 3 miles east, is one of the historic houses in the wider area around Charndon. Older roofs in the wider area can hide decades of patch repairs, so the detail matters.
Charndon is about 6 miles east of Bicester, in Oxfordshire. Houses, flats, blocks and commercial buildings in Charndon can all book flat roof surveys, with a written report and photographs every time. Our Oxfordshire coverage includes Charndon. You can also see our page for Oxford.

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:
- Book a survey every few years
- Keep outlets clear of leaves and moss
- Ask contractors to protect the roof if they work on it
- Make sure new fixings through the roof are properly sealed
Buyers can take the findings back to the seller or the agent. You might ask for work to be done before completion, or discuss the price, depending on the findings.
Small defects are simpler to deal with while they’re still small. Prompt repairs tend to add years to a flat roof.
What happens on the day
There isn’t much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll take it from there. A typical survey takes an hour or two for a small flat roof at home, and longer for a large commercial one. For a village or hamlet like Charndon, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. The roof is looked at from ground level, from windows, from the loft where there is safe access and from the roof where it’s safe.
- First we go through the roof, what’s beneath it and any problems so far.
- The roof is viewed from safe positions, including the roof itself where that’s safe.
- We check the covering for splits, blisters, ponding and wear.
- We photograph and record the outlets, upstands, trims and rooflights.
- A written report with photos and recommendations is emailed to you.
Getting ready for the survey
- Move anything stored under the loft hatch
- If you are buying, check with the agent that we can get in
- Point out any leaks or damp patches
Getting a price
Booking is simple: just ring 07833 053749 or email us, let us know about the property and we’ll explain which survey suits. We confirm the price before anything is booked.

Why it is worth a survey now in Charndon
A leak over an office, shop or unit can affect the people and stock underneath. Surveying the roof in good time means work can be planned and budgeted around the people who use the building. Older cottages and farmhouses around Charndon can have roof timbers that have been there a very long time, and water through a failed covering can rot timber if it’s left.
Every price we give includes VAT, and the report is not charged as an extra. Flat roof survey starts from £150, including VAT. Where your roof sits in the range depends on its size, height and access.
