How a flat roof survey works in Force Green
Water through a flat roof does not always come in where the stain is. It can run along the deck from a split, an open lap or a failed upstand some distance away. Our survey covers the whole roof, not just the part above the mark, with photos of anything that could be letting water in. Whoever carries out the work then has a clear starting point. Typical surveys look at blocked or damaged outlets and cracked or split membrane, across mastic asphalt, upstands and outlets and EPDM rubber.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in Force Green, the roof above may belong to the building rather than one flat.
If any part of the flat roof couldn’t be seen safely, we say so in the report. That way, it’s clear what was covered and what wasn’t, and what we’d suggest next.

Practical tips
There’s plenty you can do without going near the roof. Here’s what helps most:
- Treat rooflights and old sheeting as fragile
- Limit foot traffic on the covering
- Watch the ceilings below the flat roof for stains
- Check from a window for ponding after heavy rain
Once we have been, the findings are written up with photos. It explains the covering, its condition and every defect, and what we recommend. Turnaround is within 48 hours for a Basic Survey, 24 to 48 hours for a Standard Survey and the same day for a Premium Survey.
Book a survey every few years, and again after new fixings, units or rooflights go in. You’ll spot changes early and have a record to look back on.
When to book a survey in Force Green
The surface of a flat roof heats up and cools down far more than the rooms below. That movement pulls at seams, laps and the joints between boards, and in time it can open up splits and cracks. Older coverings that have lost their flexibility are the most likely to suffer.
Signs worth acting on include:
- Blisters and bubbles in the covering
- Loose or cracked edge trims
- Pools of water lying on the roof
- Outlets choked with leaves and silt
If your home is one of the older ones in the streets near Church of St Mary the Virgin, the joins between later flat roofs and the old walls are where problems normally start.
Questions to ask before booking
- What happens after the report arrives
- What they won’t be able to tell you
- Which viewpoints they use to see the roof
- Do they have a CAA Flyer ID and Operator ID for drone work?
What affects the cost of flat roof surveys
Every roof is different, so prices are confirmed before you book. These are the things that affect it:
- The package you choose: Basic, Standard or Premium
- If the survey needs thermal imaging or a drone
- How many separate roofs there are, such as extensions, dormers and garages
- Height and safe access
Simple, low roofs take less time to survey than tall or complicated ones, and the package you pick makes a difference too. We will give you the figure before anything is booked.
What to let us know when you contact us
These details help when you get in touch:
- When you need the report by
- Whether there’s a loft hatch, a shared roof or tricky access
- The style of property, from a terrace to a block
- Where any leaks, stains or damp patches show inside
Prices start from £150, including VAT. The exact figure depends on the roof and the package, so ring 07833 053749 or use the contact form with the details.
The survey, step by step
The visit has one job: to see as much of the flat roof as can safely be seen and record it clearly. Notes and photos go into the written report. The visit usually takes an hour or two for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. In a London area like Force Green, the main things to sort out are parking and access: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at what can safely be seen from the ground, windows, the loft and, where it’s safe, the roof itself.
- 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 is 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.
- You get a report setting out the condition and our recommendations, in order of urgency.
Before the survey
- Agree roof access with the managing agent if it’s shared
- Let us know about parking near the property
- Keep pets in another room

Advice
Local flat roofs in Force Green
Quebec House, about 0.8 miles south, is one of the historic houses in the wider area around Force Green. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. 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. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For landlords with property near Oxted station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. For a London address like Force Green, it is useful to know about controlled parking before the day.

Felt, asphalt, EPDM, GRP and single-ply roofs are all covered. If you don’t know what your roof is, we’ll identify it on the day.

Yes, where the survey calls for it and there is safe access. We look for staining, damp, daylight and signs of movement, as far as the space allows.
Will you fly a drone over my roof?
Where it helps and it’s safe, yes. Whether we can fly on the day depends on the weather and the airspace rules. We hold a CAA Flyer ID and Operator ID.
