Flat roof survey in Forty Green
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. That way, defects are found before they reach the room below. If you’ve noticed dips that suggest the deck is deflecting and blocked or damaged outlets, a survey will tell you what’s going on, on upstands and outlets, felt flat roofs and GRP fibreglass alike.
Older buildings in small places like Forty Green may be 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. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
The report doesn’t just list problems. For each finding, it explains what it is, why it matters and what we’d recommend.

Different roofs, different checks
Felt and built-up roofs
Built-up felt is one of the most common flat roof coverings on extensions, garages and dormers. We look for blistering, cracking, split laps and worn mineral surfacing.
Mastic asphalt
Without seams, asphalt tends to fail through cracking and at its skirtings. We record any crazing or splits and where water may be getting in.
What this survey can’t tell you
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- A fixed date for when the roof will need replacing
- Whether the deck or joists are strong enough
- Asbestos testing, which needs a specialist asbestos surveyor
If in doubt, ring 07833 053749 or send us an email and we will recommend the right survey. What a survey covers and does not.
What we check
- EPDM rubber
- Upstands and outlets
- Mastic asphalt
- Felt flat roofs
- Single-ply membranes
- GRP fibreglass
FAQs for Forty Green
Will you come out to Forty Green?
We do. A small place gets exactly the same survey as a big one, with the route planned beforehand.
Do you carry out roof surveys in Forty Green?
We do. The survey and report are the same in Forty Green as anywhere else, and visits run on weekdays and weekends.
Should I worry about standing water on my flat roof?
Ponding is worth looking into. It frequently means a blocked outlet, poor falls or a dipping deck, and water that sits wears the covering sooner. We record where it sits and the likely cause.
Are you insured?
Our surveys are covered by professional indemnity and public liability insurance. Ask if you need details for a managing agent or building owner.
Can you survey a flat roof on an office or unit?
Yes. Commercial and residential flat roofs are both covered. Expect about 3 to 4 hours on site for most commercial roofs, and larger roofs are quoted for their size.
Can you inspect my roof with a drone?
Where it is applicable and safe, yes. We are a CAA-registered drone operator (Flyer ID and Operator ID), flying a sub-250g drone. Drone inspection is part of the Drone Roof Survey and the Premium Survey, where it applies.
How long is the visit?
Time on site depends on the roof, but most surveys take roughly 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. The report is sent afterwards by email.
How it works
The visit typically starts outside and finishes in the loft: outside views come first, then the loft space if there is safe access. All told, expect about 1–2 hours at a typical home, and more on a big or complicated roof. Somewhere as small as Forty Green, access is frequently the only tricky part. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
- First you give us the address, what the roof covers and any leaks you’ve noticed.
- The roof is inspected from safe viewpoints, and from the roof itself where that is safe.
- The covering, falls, upstands, outlets, edge trims and rooflights are checked and photographed.
- We check the rooms or spaces under the roof for staining where we can reach them.
- You get a written report with photos and our recommendations.
How to prepare
- Gather any invoices or paperwork from past roof work
- Keep pets inside or away from the areas we’re looking at
- Mention any parking restrictions on your street

Why get it checked now?
A small split in a flat roof is normally a modest job when it is found early. Leave it, and water can get into the insulation and deck, which can turn a patch into a replacement. Surveying it now tells you where you stand. For an older or listed building in a place like Forty Green, repairs may need matching materials and consent, so a defect found early gives time to plan the work properly.
Flat roof survey starts from £150, including VAT. Basic starts from £150, Standard from £250 and Premium from £400, VAT included, and we will tell you which fits.

Local flat roofs in Forty Green
Historic houses such as Cliveden, about 4.1 miles south, show how far back building in the area around Forty Green goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material. A number of Buckinghamshire villages keep thatched roofs on their older buildings. Older houses in the South East often 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.
Take a building like Holtspur School & Pre-School: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. For landlords with property near Beaconsfield station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

What we’re asked to look at in Forty Green
No flat roof covering lasts for ever. Felt roofs frequently last around 15 to 20 years, EPDM frequently 30 to 50 years and GRP up to about 30, though workmanship and upkeep make a big difference. We can tell you how your roof is doing, whatever its age.
A survey makes sense if you’ve noticed:
- Failed upstands where the roof meets a wall
- Damaged trims at the roof edge
- Water getting in at rooflights
- Blistering in felt or asphalt
For an older house near a landmark like Church of St Michael and All Angels, the flat roofs on later extensions tend to wear out long before the main roof.
