About our flat roof survey in Longlands
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. We record where water sits, check the outlets and look for dips that suggest deflection. Where the deck may be a structural issue, our report says a structural engineer should look at it. If you’ve noticed ponding water that doesn’t drain away and gaps at upstands and abutments, we can find out what’s behind it.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, and each fails in its own way. Which one is on a roof in Longlands shapes how it is checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
Report times depend on the survey you book: the Basic Survey within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey on the same day.

What we can’t see
A survey is a proper look at the flat roof, but it can’t do everything. The main limits are:
- Hidden layers beneath the covering
- Asbestos testing, which needs a specialist asbestos surveyor
- An exact number of years the roof has left
If you’re not sure which survey you need, call 07833 053749 or email us and we’ll give you a straight answer before you book. The full list of what we check.

What affects the price in Longlands
The price reflects the time and kit the roof needs. That comes down to:
- Roof area
- How complicated the roof is, with its valleys, chimneys and parapets
- The number of roofs, including extensions and garages
- Building height and the viewpoints available
Our price is from £150, including VAT. What you pay depends on the size and height of the roof, how it can safely be seen and the package you choose.
Getting in touch
A little information up front helps. Please include:
- Your postcode, so we can check access and travel
- Pictures from the garden or a window, if you have them
- The style of property, from a terrace to a block
- Any marks or damp showing indoors
To arrange a survey, ring 07833 053749 or drop us an email with the address and what you’d like to know about the roof. We will confirm the price before you book.
Why it’s worth a survey now in Longlands
A small split in a flat roof is normally a modest job when it is found early. Left alone, water can soak the insulation and the deck, and the job grows. Surveying it now tells you where you stand. Any roof job in Longlands means planning around parking, neighbours and access. Knowing what’s needed early gives you time to plan it calmly, rather than in a rush after a leak.
One thing that affects the price is the package: from £150 for Basic, £250 for Standard and £400 for Premium, inc. VAT. Size, height and access can affect the price too.

Flat roofs in Longlands
With Eltham Palace about 2 miles north-west, Longlands sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, 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. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Landlords with a home close to New Eltham station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak. For a London address like Longlands, it’s useful to know about controlled parking before the day, along with any off-street space. Take an older house close to Christ Church: the flat roofs on later extensions tend to wear out long before the main roof.
Longlands is about 1 mile west of Sidcup, in Greater London. We provide flat roof surveys for homes and businesses in Longlands. Longlands is one of the places in Greater London where we work. For surveys nearby, see our London page.

Tips that help
A little preparation and a few simple habits help, both for the survey and for the roof itself. Some pointers:
- Limit foot traffic on the covering
- Note any new marks on ceilings beneath the roof
- Check the outlets after the leaves fall
- Have the roof looked at again after a severe storm
If anything in the report isn’t clear, just ask us. Standard Surveys come with a follow-up consultation, and Premium Surveys with an in-person one, so you can talk the findings through.
Keep outlets, gutters and hoppers clear, particularly after the leaves fall. A flat roof that drains well wears much more slowly.

Common questions in Longlands
Is Longlands in the area you cover?
Yes, Longlands is one of the places we work. Every survey there gets the same written report with photos.
Is parking a problem for a survey in Longlands?
It rarely stops a survey, but it is worth planning. Let us know the parking rules on your street and we’ll work around them.

Do you look in the loft space?
Where it is relevant to the survey and there’s safe access, yes. Please clear anything stored under the hatch.
How long is the visit?
Expect it to take roughly 1–2 hours for a house, though large, tall or awkward roofs take more time. You will then get the report by email, on the timescale of your package.
How much does a flat roof survey cost in Longlands?
Flat roof survey starts from £150, including VAT. What you pay for your roof depends on its size, height, access and the package, confirmed before anything is booked.
Do I have to be there for the survey?
Not always. If we only need the outside, we can agree that beforehand, but anything inside needs someone there to give access.
How it works
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes roughly 1–2 hours for a small flat roof at home, and longer for a large commercial one. If you have questions on the day, just ask. In a London conversion, the way into the loft space is often from a communal landing or the top flat. Where that is the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Longlands runs like any other.
- We start with the details: the address, the roof’s use and any leaks or stains.
- We view the roof from ground level, from windows and from the roof where it is safe to do so.
- We check and photograph the covering, the falls, the upstands, the outlets, the trims and any rooflights.
- We check the rooms or spaces under the roof for staining where we can reach them.
- We send a written report with photos, the defects we found and what we recommend.
Getting ready for the survey
- Gather any invoices or paperwork from past roof work
- Keep pets in another room
- Make sure we can get to the back of the property
