What you can safely check yourself
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, as it helps a surveyor trace the cause.
Flat roof survey in Blacknest
Offices, shops, industrial units and blocks of flats often sit under large flat roofs. On a roof like this, a survey shows where the covering is wearing, where water is ponding and which outlets need attention. We record the condition with photos so work can be planned and budgeted. Commercial roofs are quoted for their size and access, so please ring 07833 053749 or send us an email with the address and an idea of the roof’s size. We survey GRP fibreglass, EPDM rubber and single-ply membranes, and people most frequently book us about outlets choked with leaves and silt and failed seals around rooflight kerbs.
In a village or hamlet like Blacknest, flat roofs are usually on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included when you book.
The report works through the roof section by section, from the main slopes down to the gutters and outlets. You’ll see the good as well as the bad.

What we look for on each type of roof
Mastic asphalt
Asphalt has no laps, so its weak points are cracks and the skirtings at walls and upstands. We record any crazing or splits and where water may be getting in.
Rooflights and upstands
Where a flat roof meets a wall, the upstand has to stay sealed as the building moves. We check for splits, gaps and loose flashings above the upstand.
What happens if roof problems are left?
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. A survey now shows which you’re dealing with. Where a roof is exposed, as many are in small places like Blacknest, driving rain gets into any weakness, and damp in older walls is slow to dry out.
A Basic Survey starts from £150, including VAT. The Standard Survey starts from £250 and the Premium Survey from £400. You will know the price for your survey before booking.

Blacknest questions
Is Blacknest within the area you cover?
Yes, we do. Our area covers London and the South East, from towns to the smallest villages. Longer journeys are simply planned in advance.
Is my home in Blacknest listed or in a conservation area?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
Does someone need to be in?
Not necessarily. If we only need the outside, we can agree that beforehand, but the loft and any rooms with damp need someone to let us in.
How much does a flat roof survey cost in Blacknest?
Flat roof survey starts from £150, including VAT. What you pay for your roof depends on its size, height, access and the package, and it is agreed before booking.
Which days do you carry out surveys?
Visits run seven days a week in the daytime, which suits people who work during the week. Just say which days work for you.
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 is not a structural engineer’s report. Many buyers use it alongside a building survey.
When does the report arrive?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. Each one is emailed.
When you need someone else
No survey can tell you everything, and we’d rather be clear about that before booking. Keep these in mind:
- What’s under the membrane without opening it up
- Parts of the roof that are not safe to walk on or view
- Structural calculations, which need a structural engineer
If in doubt, ring 07833 053749 or use the contact form and we’ll point you to the right survey before you book. What our survey covers.

What we do, step by step
The aim of the visit is simple: to see as much of the flat roof as can be seen safely and record it clearly. Notes and photographs go into the written report. It typically takes about 1–2 hours on an ordinary house, with bigger or more complicated roofs taking longer. In a small place like Blacknest, access is normally the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- We start with the address and, on larger roofs, the roof area and access.
- We check the rooms or spaces under the roof for staining where there’s access.
- We view the roof from safe positions and never walk on fragile surfaces.
- We record every defect with a photo and its likely cause.
- You get a report setting out the condition and our recommendations, in order of urgency.
Getting ready for the survey
- Dig out any old roof reports or invoices
- Tell us about any leaks, stains or damp patches you know of
- If you are buying, let the agent know when we’re coming

Advice
Flat roof surveys around Blacknest
Farnham Castle, about 4.1 miles north-east, is one of the historic houses in the wider area around Blacknest. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material. Thatch survives on some older buildings in Hampshire’s villages. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
For landlords with property near Bentley (Hampshire) station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
