About our flat roof survey in Lower North Dean
Each type of flat roof has its own weak points. Felt can blister and crack, asphalt can craze and split, EPDM seams and laps can lift, and GRP can crack where boards meet or at the trims. On PVC and TPO single-ply roofs, we look closely at the welded laps, edges and fixings. Knowing what you have and how it is doing helps you plan what comes next. If you’re worried about outlets that hold water back and signs of deflection in the roof deck, we can find out what’s behind it, on single-ply membranes, upstands and outlets and felt flat roofs alike.
In a small place like Lower North Dean, 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 usually the first part of a flat roof to go.
Nothing in the report is left vague: if work is needed, the report says so clearly, along with how urgent it is.

How it works
Every roof is different, but as a rough guide the survey takes about one to two hours for a house, rising to roughly 3–4 hours on a commercial building. If you have questions on the day, just ask. Older roofs in small places like Lower North Dean can have low, tight loft spaces, so let us know about the loft hatch and any ladder. We only go where it’s safe.
- First we go through the roof, what’s beneath it and any problems so far.
- 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.
Getting ready for the survey
- Tell us where we can park nearby
- Have any paperwork from past roof work to hand
- Leave a clear route to the loft

Advice
What we are asked to look at in Lower North Dean
Flat roofs frequently get walked on for other jobs: to clean windows, fit aerials or air conditioning units, or reach a gutter. A covering that wasn’t designed for foot traffic can crack or puncture. Fixings added through the covering often start leaks too.
Problems we come across often include:
- Edge trims that have lifted or split
- Pools of water lying on the roof
- Outlets choked with leaves and silt
- Failed seals around rooflight kerbs
For landlords with property near Saunderton station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Choosing a roof surveyor
- Their report turnaround times
- Will they check the loft as well as the outside?
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Whether VAT is in the quoted price
What a flat roof survey looks like in Lower North Dean
Historic houses like Hughenden Manor, about 1.8 miles south, show how far back building in the area around Lower North Dean goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Thatch survives on some older buildings in Buckinghamshire’s villages. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
For site and facilities teams at buildings such as Hughenden Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. If yours is one of the older homes in the streets near Speen Church (Baptist), the joins between later flat roofs and the old walls are where problems normally start.

What we look for on each type of roof
Rooflights and upstands
The joins around rooflights and at upstands are common leak points. We check the seals and the covering around each one.
GRP fibreglass
Movement in the deck or a thin layer of resin can lead to cracks in GRP. Our report notes cracks and any sign that the deck is flexing.
Lower North Dean questions
Is my home in Lower North Dean listed or in a conservation area?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Is Lower North Dean within the area you cover?
Yes, Lower North Dean is on our map. A small place gets exactly the same survey as a big one.
Can you find where water is getting through my flat roof?
We check the whole roof, since water can travel before it shows inside. Every split, lap, upstand, outlet and rooflight we can see is looked at. If the cause cannot be seen, we will say so and suggest what would help.
Do you need to get into the loft?
Yes, where the survey calls for it and there’s safe access. We look for staining, damp, daylight and signs of movement.
How much does a flat roof survey cost in Lower North Dean?
Flat roof survey starts from £150, including VAT. Our three packages are Basic from £150, Standard from £250 and Premium from £400, including VAT.
What types of flat roof do you survey?
We survey felt and built-up roofs, mastic asphalt, EPDM rubber, GRP fibreglass and single-ply PVC and TPO. If you don’t know what your roof is, we will identify it on the day.
Do you check flat roofs for asbestos?
We do not carry out asbestos surveys. 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.
