Cholsey Flat Roof Survey
Flat roof surveys in Cholsey, with over 20 years’ experience behind it. You get a clear report with photographs.
- Blisters and bubbles in the covering
- Cracked or split membrane
- Leaks around rooflights
Different roofs, different checks
EPDM rubber
EPDM is a synthetic rubber membrane, often laid in a single sheet on smaller roofs. The survey looks at laps, edge trims, corners and signs of puncture.
Rooflights and upstands
Rooflights, lanterns and upstands are where many flat roof leaks begin. We check the seals and the covering around each one.
Flat roof survey in Cholsey
Water through a flat roof does not always come in where the stain is. It can run along the deck from a split, an open lap or a failed upstand some distance away. Our survey covers the whole roof, not just the part above the mark, with photographs of anything that could be letting water in. Whoever carries out the work then has a clear starting point. We’re frequently asked to look into ponding water that doesn’t drain away and failed upstands where the roof meets a wall, on GRP fibreglass, felt flat roofs and upstands and outlets.
In a smaller place like Cholsey, some flat roofs sit in the open, where wind can catch loose edges and trims. Felt and bitumen also age in strong sun. The signs are splits, blisters and edges coming away, along with water that sits after rain. A flat roof that still holds water days after rain is also worth a closer look.
We keep jargon out of it: if work is needed, the report says so clearly, and where it can wait, that is said too.

What this survey can’t tell you
Some things can’t be seen without opening up the roof, so a survey has limits:
- A promise that the roof won’t leak in future
- Areas we can’t see or reach safely, including fragile rooflights and sheeting
- Asbestos testing, which needs a specialist asbestos surveyor
If in doubt, call 07833 053749 or email us and we will suggest the right survey. What a survey covers and does not.

Local flat roofs in Cholsey
Older buildings in west Oxfordshire often have Cotswold stone slate roofs, and some Oxfordshire villages still have thatch. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. About 2.9 miles north lies Brightwell Manor, a reminder of how long the area around Cholsey has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
Take an older house close to Church of St Mary: any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. Anyone responsible for a site like Cholsey Primary School will know that a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.
Cholsey is about 5 miles south-east of Didcot, in Oxfordshire. From houses to flats and shops in Cholsey, we can survey the roof. We cover towns and villages across Oxfordshire, large and small. Reading is in our area too.
Postcode districts we cover here for flat roof surveys: OX10. Local streets include Station Road, Church Road and Lapwing Lane, and we cover them all. We also cover Winterbrook (1 mile north-east), North Stoke (1 mile east), Moulsford (1 mile south), South Stoke (2 miles south) and Mongewell (2 miles north-east). Within a short drive, we also cover Oxford (13 miles north), Didcot (5 miles north-west), Abingdon-on-Thames (9 miles north-west), Thame (14 miles north-east), Wantage (12 miles west) and Henley-on-Thames (11 miles east).
Near you in Cholsey
Around Cholsey, our work takes us to homes and buildings near Wallingford School, Cranford House School and Morning Star pub. Cholsey has its own railway station: Cholsey station. Well-known places in the area include Wallingford Castle (2.4 miles north-east). Open spaces near Cholsey include Cholsey Marsh and Wittenham Clumps.
Rented homes, blocks and businesses
Letting agents can arrange access with tenants, at a time agreed ahead of time. We survey on weekdays and at weekends, which helps when tenants work during the week.
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait.
Cholsey: your questions answered
Is my home in Cholsey listed or in a conservation area?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Is Cholsey within the area you cover?
Yes, we do. We cover the whole of London and South East England, from towns to the smallest villages. The journey is planned ahead, so it is useful to know about access.
Can you find where water is getting through my flat roof?
We check the covering and every detail where leaks commonly start, recording anything that could let water through. If the source is hidden, we may suggest a leak investigation or electronic leak detection.
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, with larger roofs quoted on their size.
What’s in the survey report?
It works through the roof part by part, in writing and with photos, finishing with recommendations. Points are put in order of urgency where relevant.
When does the report arrive?
Each package has its own report time. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. Mention any deadline when you book.
Which days do you carry out surveys?
Visits run seven days a week in the daytime, which suits people who work during the week. Just say which days work for you.
Tips from our surveys
Small things make a difference. Our tips:
- Check that new brackets or units haven’t damaged the covering
- Note where water lies after a downpour
- Keep people off the roof unless they need to be there
- Keep clear of rooflights and fragile roof sheets
You can use the report to ask roofers to quote for the same work. Because everyone is pricing the same findings, the quotes are easier to compare. You stay in control of who does the work and when.
Book a survey every few years, and again after new fixings, units or rooflights go in. You will spot changes early and have a record to look back on.
What else we do in Cholsey
When to book a survey in Cholsey
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.
These are some of the problems a survey can pick up:
- Cracked or split membrane
- Raised blisters across the surface
- Outlets choked with leaves and silt
- Upstands pulling away from walls
Landlords with a home close to Cholsey station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Before booking any roof surveyor
- Whether you can ask questions once you have the report
- What exactly goes into their report
- Will they check the loft as well as the outside?
- Their track record with similar roofs
What happens on the day
A survey visit follows a simple order: we listen to what’s been worrying you, look at the roof from every safe viewpoint, photograph what we find and record our findings for the written report. It typically takes about one to two hours for a small flat roof at home, and longer for a large commercial one. In a smaller place like Cholsey, as anywhere, the forecast plays a part: the parts that need calm, dry weather are planned around it.
- We agree the roof to be surveyed, its use and any leaks you know about.
- The roof is viewed from safe positions, including the roof itself where that is safe.
- The covering is checked for wear, splits, blisters and standing water.
- We photograph and record the outlets, upstands, trims and rooflights.
- The report, with photos and recommendations, comes to you by email.
Before the survey
- For flats, check roof access has been agreed
- Let us know about parking before the day
- Make sure pets are kept safely away
Arrange a survey
Photos help, if you have them. Take them safely from ground level or a window; never climb up to get a better view. To get started, call 07833 053749 or send us an email.
