Flat roof surveys for homes and businesses in Crowell Hill
A flat roof leak frequently travels before it shows on the ceiling. It can run along the deck from a split, an open lap or a failed upstand some distance away. That’s why we check every detail across the roof, not only the area above the stain, with photographs of anything that could be letting water in. A roofer can then start from a clear picture of the problem. Common reasons to book are cracked or split membrane and outlets choked with leaves and silt, on GRP fibreglass, felt flat roofs and single-ply membranes.
Some older homes in villages like Crowell Hill are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.
If any part of the flat roof couldn’t be seen safely, we say so in the report. That way, it is clear what was covered and what wasn’t, and what we’d suggest next.

Useful tips for Crowell Hill property owners
There is plenty you can do without going near the roof. What helps most:
- Book a survey every few years
- Note where water lies after a downpour
- Ask contractors to protect the roof if they work on it
- Keep records of when the roof was laid and what work has been done
Once we’ve been, the findings are written up with photos. It explains the covering, its condition and every defect, and what we recommend. Basic reports arrive within 48 hours, Standard reports in 24 to 48 hours and Premium reports the same day.
Check the roof from a window after a downpour. Water still lying a day or two later is worth getting looked at.

How we price flat roof surveys
When we price a survey, we consider:
- Which survey package you book

- The type of building, from a house to a block or an office
One thing that affects the price is the package: Basic from £150, Standard from £250 or Premium from £400, all including VAT. Size, height and access can affect the price too.

Crowell Hill: your questions answered
Will you come out to Crowell Hill?
Yes. Crowell Hill is within the area we cover, which takes in towns, villages and rural addresses. We work right across London and South East England. Let us know about access, parking and anything unusual about getting there when booking.
Do you cover Crowell Hill?
We do. Every survey there gets the same written report with photographs.
Can you inspect my roof with a drone?
Yes, where it’s applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
Should I worry about standing water on my flat roof?
Standing water a day or two after rain typically needs attention. The cause may be the outlets, the falls or the deck. The survey looks at each and records the likely cause.
How long will you be at the property?
That depends on the size and shape of the roof; most visits take roughly 1–2 hours at most homes, though large, tall or awkward roofs take more time. The report is sent afterwards by email.
Can you test old roof sheets for asbestos?
Our survey doesn’t include asbestos testing. Older buildings, from before 2000, may have asbestos in cement sheets or soffits. Anything that might contain it is flagged, so a specialist asbestos surveyor can check before work starts.
Do you carry out surveys on Saturdays and Sundays?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Just say which days work for you.
Signs you need a flat roof survey in Crowell Hill
Water that does not drain sits on the roof and speeds up wear. It typically comes from poor falls, a blocked outlet or a deck that has dipped. Where trees are close by, leaves and silt can block an outlet within a single autumn.
A survey can pick up problems such as:
- Blistering in felt or asphalt
- Water getting in at rooflights
- Splits and cracks in the covering
- Blocked or damaged outlets
Landlords with a home close to Saunderton station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.

How the survey works
Every visit follows the same pattern: we listen to what’s been worrying you, inspect the roof from every safe viewpoint, photograph what we find and record our findings for the written report. Most visits take about 1–2 hours for most houses, rising to roughly 3–4 hours on a commercial building. Somewhere like Crowell Hill needs a little journey planning: let us know about lanes, gates and parking. On the day, we inspect whatever is safely visible, inside and out.
- You tell us about the roof, its covering if you know it, and any leaks.
- The roof is inspected from safe viewpoints, and from the roof itself where that is safe.
- 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’s access.
- We send a written report with photos, the defects we found and what we recommend.
Preparing for the visit
- Buyers: confirm access with the estate agent or seller
- Jot down any questions you want answered
- For flats, make sure roof access has been agreed
How to book
Getting a price is simple: just ring 07833 053749 or send us an email and give us some details about the property and we will suggest the right survey. The price is agreed up front.
Advice
Flat roofs in Crowell Hill
Adwell House, about 3.9 miles west, is one of the historic houses in the wider area around Crowell Hill. 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. West Oxfordshire’s older buildings often carry Cotswold stone slates, and a few villages in the county keep their thatch. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
For an older house near a landmark like Church of the Nativity of the Blessed Virgin Mary, flat-roofed rear additions and dormers added over the years are worth checking.
