How a flat roof survey works in Bell Green
Flat roofs deal with rain in a very different way from pitched ones. Water lies on the surface for longer, so a small split or a blocked outlet can soon lead to a leak. We check the surface, the falls, the upstands and the edge trims, and we look for signs that water has reached the deck. That way, defects are found before they reach the room below. Common reasons to book are signs of deflection in the roof deck and water getting in at rooflights, on GRP fibreglass, upstands and outlets and single-ply membranes.
On a London roof terrace or a flat roof over a back addition, water often runs under the covering before it shows. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a converted house in Bell Green, the roof above may belong to the building rather than one flat.
The written findings come by email, easy to pass on to a roofer, an agent or an insurer. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

Common questions in Bell Green
Can parking be tricky for a visit in Bell Green?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you cover Bell Green?
Yes, Bell Green is within the area we cover. Our area covers London and the South East. You can call 07833 053749 or email us with the address and a few details, and we will talk through which survey suits.
How much does a flat roof survey cost in Bell Green?
Our price is from £150, including VAT. Our Basic Survey starts from £150, the Standard Survey from £250 and the Premium Survey from £400, all including VAT.
What do I do with the report?
The report comes by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
Do you use drones?
Where it helps and it is safe, yes. Flights depend on the weather on the day and airspace rules. We hold a CAA Flyer ID and Operator ID.
Is a flat roof survey the same as a building survey?
No. It is a survey of the flat roof. It is not a RICS Level 2 or 3 home survey or a structural engineer’s report. It frequently sits alongside a buyer’s building survey.
Do you carry professional indemnity insurance?
We’re covered by professional indemnity and public liability insurance, for every survey we carry out.
When to book a survey in Bell Green
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, though workmanship and upkeep make a big difference. We can tell you how your roof is doing, whatever its age.
Things that often lead to a survey include:
- Blocked or damaged outlets
- Blistering in felt or asphalt
- Water getting in at rooflights
- Splits and cracks in the covering
If yours is one of the older homes in the streets near St Michael's and All Angels, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
What to check before booking
- Whether they hold professional indemnity and public liability insurance
- How much experience they have with roofs like yours
- Their drone registration, if they fly one
- When you’ll get the report
Flat roof surveys in Bell Green: local notes
Historic houses such as Kingswood House, about 2.1 miles west, show how far back building in the area around Bell Green goes. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead. Inner London’s Victorian and Edwardian terraces often have Welsh slate roofs. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For businesses in and around places such as Lewisham Shopping Centre, a flat roof over a business is out of sight and out of mind until it leaks. If you look after a building like Haseltine Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

The survey, step by step
We photograph the roof as we go, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available, including by drone where it is applicable and the weather allows. Most surveys take about 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. In converted houses and mansion blocks, the loft hatch is often on a shared landing. Where that’s the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- 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.
- We view the roof from safe positions and never walk 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.
Getting ready for the survey
- Point out any leaks or damp patches
- Find any records of previous roof work
- Mention any parking restrictions on your street

What you can safely check yourself
A DIY look is useful, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground, and those are details a survey looks at closely.
A lot can be seen from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
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.
GRP fibreglass
GRP can crack if the deck beneath flexes or if the resin was laid too thin. We record any cracking and any signs of the deck moving.
