How a flat roof survey works in Oakwood
Ponding is often the first sign that something on a flat roof is not right. It can mean the falls were never right, an outlet is blocked or the deck has started to sag. The survey notes any ponding, the state of each outlet and any dips that hint at a sagging deck. If the deck itself looks like a structural concern, we’ll recommend a structural engineer. We are often asked to look into blocked or damaged outlets and upstands pulling away from walls, across upstands and outlets, felt flat roofs and GRP fibreglass.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Every penetration and upstand is a place where a membrane can fail. For a building in Oakwood, access is agreed with whoever manages the roof before the visit. Plant bases, rooflights and cable entries are all places where water can get in.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

Why it is worth a survey now in Oakwood
Caught early, a split or open seam in a flat roof is often a small repair. Left alone, water can soak the insulation and the deck, and the job grows. A survey now shows which you are dealing with. Many older London roofs have only old felt under the slates, or no underlay at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left alone, that means wet timbers and plaster, which is a far bigger job than the roof fault itself.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. Flat roof survey starts from £150, including VAT.

What a flat roof survey doesn’t cover
In fairness, there are limits to any roof survey:
- Whether old sheeting or boards contain asbestos
- A promise that the roof will not leak in future
- The condition of the deck or insulation hidden under the covering
If in doubt, call 07833 053749 or use the contact form and we will suggest the right survey. What a survey covers and does not.
What this survey covers
- EPDM rubber
- Mastic asphalt
- GRP fibreglass
- Upstands and outlets
- Single-ply membranes
- Felt flat roofs
Different roofs, different checks
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.
EPDM rubber
Lifting at the edges and loose areas of membrane are common EPDM problems. Any we find are noted and photographed.
What we are asked to look at in Oakwood
A buyer’s general survey often recommends a closer look at a flat roof. Building owners and managing agents book to plan maintenance, or before a sale or a new lease. Either way, you get a clear record of the roof, with photos.
Signs worth acting on include:
- Dips that suggest the deck is deflecting
- Standing water left after rain
- Failed seals around rooflight kerbs
- Outlets choked with leaves and silt
If your house is among the older ones in the streets near St Thomas's Church, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
Questions to ask before you book

The survey, step by step
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes about one to two hours for a small flat roof at home, and longer for a large commercial one. You are welcome to ask questions while we’re there. In a London area like Oakwood, the main things to sort out are parking and access: let us know about parking, the floor the property is on, any shared entrance and loft access. On the day, the roof is looked at from ground level, from windows, from inside the roof space and from the roof where it is safe.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- We check the rooms or spaces under the roof for staining where there’s access.
- The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
- We record every defect with a photo and its likely cause.
- The report explains the condition and recommends what to do first.
Before we arrive
- Find any records of previous roof work
- Keep pets in another room
- Let us know about parking near the property

Common questions in Oakwood
Does a conservation area affect roof work in Oakwood?
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 Oakwood in the area you cover?
Yes, Oakwood is within the area we cover. We work right across London and South East England. You can ring 07833 053749 or email us with the address and some details, and we’ll talk through which survey suits.
Will the survey show why my flat roof is leaking?
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. Where nothing visible explains the leak, the report says what to try next.
Which flat roof coverings do you cover?
Felt, asphalt, EPDM, GRP and single-ply roofs are all covered. If you do not know what your roof is, we will identify it on the day.
Will you check the loft?
If the survey needs it and the roof space can be reached safely, yes. A clear path to the hatch helps, and if the loft can’t be reached safely, the report says so.
When does the report arrive?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email.
Do you cover flat roofs on blocks of flats?
Yes. Offices, units, shops and blocks of flats are all part of our work. Larger commercial roofs are quoted for their size and access, so ring 07833 053749 or email us with the address.

Flat roof surveys in Oakwood: local notes
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops. The wider area around Oakwood has a long history of building, with Forty Hall about 3.1 miles north-east. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area.
Take a building like Wolfson Hillel Primary School: a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail. Parking in Oakwood, as in most of London, takes a little planning: let us know about permits, visitor bays or off-street space as you book.
