What a flat roof survey doesn’t cover

- Structural calculations, which need a structural engineer
- Hidden layers beneath the covering
- Parts of the roof that aren’t safe to walk on or view

How a flat roof survey works in Apsley End
Flat roofs deal with rain in a very different way from pitched ones. Because rain sits on it for longer, a small split, an open seam or a blocked outlet matters more. We check the surface, the falls, the upstands and the edge trims, and we note any sign that the deck below has got wet. The aim is to find problems before they show up as a stain on a ceiling. We survey single-ply membranes, mastic asphalt and GRP fibreglass, and people most often book us about a sagging deck under the covering and loose or cracked edge trims.
In a village or hamlet like Apsley End, flat roofs are normally 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 when you book.
The written findings come by email, ready to forward to whoever needs them. Turnaround is within 48 hours for Basic, 24–48 hours for Standard and same day for Premium.

The survey, step by step
Safety comes first on every visit. We inspect what can be seen safely, and anything we cannot see is noted in the report. The survey normally takes about 1–2 hours for a small flat roof at home, and longer for a large commercial one. Cottages and farmhouses around Apsley End often have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can safely be seen.
- You tell us about the roof, its covering if you know it, and any leaks.
- We view the roof from ground level, from windows and from the roof where it’s safe to do so.
- Every part of the roof we can see is checked: covering, falls, upstands, outlets, trims and rooflights.
- Where there is safe access, we look at the ceilings and spaces below for signs of water.
- You get a report with photos and our recommendations.
How to prepare
- Have any paperwork from past roof work to hand
- Unlock side gates and any roof access doors
- Keep pets out of the way during the survey

Flat roof surveys in Apsley End: local notes
What can be done to an older roof may depend on listing or a conservation area. Your council and Historic England’s list will tell you where you stand, ideally before any re-roofing is planned. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
Anyone responsible for a site like Shillington Lower School will know that a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.

Tips from our surveys
You don’t need to be a roofer to help. Here’s what helps most:
- Keep records of when the roof was laid and what work has been done
- Check the outlets after the leaves fall
- Keep people off the roof unless they need to be there
- Look for standing water a day after rain
After the visit, we write up the report with photographs of what we found. It covers the type of covering, its condition and each defect, with our recommendations. Turnaround is within 48 hours for a Basic Survey, 24 to 48 hours for a Standard Survey and the same day for a Premium Survey.
After heavy rain, look at the roof from an upstairs window if you can. Water still lying a day or two later is worth getting looked at.
What happens if roof problems are left?
Waiting for a stain inside means the water has already got through the layers. A survey can find worn areas and failing details before that point, so you can plan the work rather than react to it. Around Apsley End, older homes often have old roof timbers, where water from a failed roof can cause rot if it’s left.

When to book a survey in Apsley End
Flat roofs swing between hot and cold more than most parts of a building. That movement pulls at seams, laps and the joints between boards, which can open splits and cracks over the years. Coverings that have hardened with age tend to suffer most.
Common reasons to book include:
- Ponding water that doesn’t drain away
- A sagging deck under the covering
- Failed upstands where the roof meets a wall
- Edge trims that have lifted or split
Take an older house close to Church of All Saints: any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
What to check before booking
- What exactly goes into their report
- Is there a chance to talk the report through?
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Their track record with similar roofs
DIY checks: what’s safe
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, which helps when we look at the roof.
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That part is for a survey, using safe viewpoints and a drone where it applies.
Questions from Apsley End
Do you cover Apsley End?
We do. The survey and report are the same in Apsley End as anywhere else, and visits run on weekdays and weekends.
How do I find out if my home in Apsley End is listed?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Is ponding on a flat roof a problem?
Standing water a day or two after rain typically needs attention. It could be the outlets, the falls or a deflecting deck. We check each of these and record what we find.
Can you give me structural calculations?
No. We are roof surveyors, not structural engineers. If we see signs that need an engineer’s opinion, we’ll recommend one.
Do you cover flat roofs on blocks of flats?
Yes. We survey flat roofs on offices, shops, industrial units and blocks of flats. Larger commercial roofs are quoted for their size and access, so ring 07833 053749 or email us with the address.
Do you need to get into the loft?
If the survey needs it and the loft space can be reached safely, yes. Please clear anything stored under the hatch.
Can you survey any kind of flat roof?
Felt, asphalt, EPDM, GRP and single-ply roofs are all covered. Not sure what yours is? We’ll tell you in the report.
