Flat roof surveys for homes and businesses in Whippendell Bottom
A flat roof survey looks at the covering, the edges, the outlets and the details where the roof meets walls and rooflights. We cover felt, mastic asphalt, EPDM rubber, GRP fibreglass and single-ply roofs. We survey extension, garage and dormer roofs as well as bigger roofs on flats, offices and units. The findings go into a written report with photos, setting out the defects and what we’d recommend. If you’ve noticed pools of water lying on the roof and failed upstands where the roof meets a wall, we can find out what’s behind it.
In a small place like Whippendell Bottom, a flat roof can stand in the open, so edges, upstands and laps take a beating. Older felt roofs, often around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are typically the first part of a flat roof to go.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

Flat roofs in Whippendell Bottom
About 3.4 miles south-west lies Chenies Manor House, a reminder of how long the area around Whippendell Bottom has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
Anyone responsible for a site like Kings Langley School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. Take an older house close to Church of St Paul: the flat roofs on later extensions tend to wear out long before the main roof.

How it works
We don’t take risks to get a closer look. Everything that can safely be seen is inspected, and anything we cannot see is noted in the report. Most visits take about 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. Cottages and farmhouses around Whippendell Bottom often have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can be seen safely, and anything we can’t see is noted.
- We agree the roof to be surveyed, its use and any leaks you know about.
- We look at the roof from the ground, windows and the roof where it’s safe.
- The covering is checked for wear, splits, blisters and standing water.
- 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
- If you are buying, check with the agent that we can get in
- For flats, check roof access has been agreed
- Keep pets out of the way during the survey

What we look for on each type of roof
Mastic asphalt
Older asphalt can become brittle and crack as the roof moves. The report shows where it is cracking and how far it seems to extend.
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.
When to book a survey in Whippendell Bottom
No flat roof covering lasts for ever. Around 15 to 20 years is common for felt, while EPDM often lasts 30 to 50 years and GRP up to about 30, although how well it was laid and looked after matters a great deal. We can tell you how your roof is doing, whatever its age.
Here are some of the things we see often:
- Raised blisters across the surface
- Upstands pulling away from walls
- A sagging deck under the covering
- Outlets that hold water back
If you let a flat or house near Kings Langley station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
What to check before booking
- How they plan to inspect the roof safely
- Whether the inside of the roof is included
- Whether any drone flown is registered with the CAA
- What follow-up you get after the report
Useful tips for Whippendell Bottom property owners
A survey works best with a little help from you, before and after. Some tips:
- Check ceilings under the roof for damp patches
- Note the date and type of any roof work
- Make sure new fixings through the roof are properly sealed
- Check from a window for ponding after heavy rain
Landlords, owners and managing agents can keep the report as a dated record of the roof. It helps when planning maintenance budgets, and it makes changes easy to spot at the next survey.
Keep foot traffic on a flat roof to a minimum. If access is needed, boards or walkways help protect the covering, and remind them never to step on rooflights or fragile sheets.
Surveys for landlords and agents in Whippendell Bottom
Businesses and commercial landlords can book us too, including offices, shops and units. Bigger roofs take more time.
Buyers’ agents can book surveys on behalf of their clients. Reports are emailed, so they’re easy to pass on.
Whippendell Bottom questions
Is my home in Whippendell Bottom listed or in a conservation area?
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.
Is Whippendell Bottom in the area you cover?
Yes, Whippendell Bottom is one of the places we work. Every survey there gets the same written report with photos.
How many years has my flat roof got left?
We don’t give a fixed number of years, because so much depends on upkeep, exposure and workmanship. Our report describes the condition and what needs doing, and when.
Is a flat roof survey the same as a building survey?
No. It’s a survey of the flat roof. It isn’t a RICS Level 2 or 3 survey of the whole building, and it isn’t a structural engineer’s report. It frequently sits alongside a buyer’s building survey.
Do you need to get into the loft?
If the survey needs it and the loft space can be reached safely, yes. A clear path to the hatch helps.
Does the weather affect the survey?
It can, depending on the survey. Drones can’t fly safely in strong wind or heavy rain, and thermal imaging works best after a sunny day, with a dry roof and little wind. We’ll rearrange with you if the weather is not right.
Does the report include photos?
Yes, every report has them. Pictures sit next to the findings they show, so you can see what we mean.
