Flat roof survey in Sidcup: what you get
A flat roof leak often travels before it shows on the ceiling. It may start at a split, a lifted seam or a failed upstand well away from the damp patch. Our survey covers the whole roof, not just the part above the mark, and photograph anything that could let water in. A roofer can then start from a clear picture of the problem. We survey felt flat roofs, mastic asphalt and upstands and outlets, and the problems we’re asked to look at most are cracked or split membrane and failed seals around rooflight kerbs.
Offices, shops and blocks of flats across London frequently have large flat roofs with plant, rooflights and walkways. Every penetration and upstand is a place where a membrane can fail. For a building in Sidcup, access is agreed with whoever manages the roof before the visit. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
The report is written in plain words, so you do not need to be a roofer to follow it. Photos show what each point refers to, and recommendations are put with the most urgent first where relevant.

How the survey changes by roof type
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.
Rooflights and upstands
Rooflights and fragile sheets are never walked on. We view them from safe positions and photograph what we see.
What a flat roof survey looks like in Sidcup
With Danson House about 1.7 miles north, Sidcup sits in an area with a long building history. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead. 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. If your home in Sidcup is one of them, bay roofs, hips and later dormers each have their own details. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
The streets around a church like Holy Trinity Church are often among the oldest in a place, and if you own one of the older houses nearby, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear. If you own a rental within reach of Sidcup station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

What we’re asked to look at in Sidcup
Many flat roof problems start at the details rather than the main surface. Upstands, trims, outlets and rooflight kerbs each move and weather in their own way. If they were rushed when the roof was laid, they’re often the first things to fail.
Common reasons to book include:
- Upstands pulling away from walls
- Failed seals around rooflight kerbs
- Splits and cracks in the covering
- Raised blisters across the surface
For site and facilities teams at buildings like Birkbeck Primary School, a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail.

How the survey works
The visit has one job: 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 usually takes roughly 1–2 hours for most houses, though large, tall or awkward roofs take more time. In a London area like Sidcup, 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. We then look at whatever is safely visible from the ground, windows, the loft and, where it is safe, the roof itself.
- First you give us the address, what the roof covers and any leaks you’ve noticed.
- We check the roof from wherever it can be seen safely.
- We check and photograph the covering, the falls, the upstands, the outlets, the trims and any rooflights.
- Inside, we look for damp and staining under the roof where there’s access.
- You get a written report with photos and our recommendations.
Preparing for the visit
- For flats, check roof access has been agreed
- Clear the way to the loft hatch
- Keep pets inside or away from the areas we are looking at

Advice
Questions from Sidcup
Is my home in Sidcup listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Will parking be an issue for a roof survey in Sidcup?
It can be, so it’s useful to tell us about permits, visitor bays or off-street space when booking. The visit is then planned around what’s available.
How do I book a survey in Sidcup?
To book, call 07833 053749 or drop us an email with the address, the type of property and what’s prompted the survey. We’ll confirm the price and agree a day with you.
Will you check the loft?
Where it is relevant to the survey and there is safe access, yes. A clear path to the hatch helps.
Do you work in Sidcup?
Yes. Our area covers London and South East England, and that includes Sidcup.
Can you survey any kind of flat roof?
We survey felt and built-up roofs, mastic asphalt, EPDM rubber, GRP fibreglass and single-ply PVC and TPO. If you don’t know what your roof is, we’ll identify it on the day.
How long is the visit?
Expect it to take about 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. You’ll then get the report by email.
Before and after the survey
Here are a few things we’d tell any owner, before and after a survey:
- Ask whoever fits equipment on the roof to make good the covering
- Check ceilings under the roof for damp patches
- Check the outlets after the leaves fall
- Plan a survey before the covering reaches the end of its usual life
If anything in the report is not 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.
Try not to let a flat roof become a walkway. Where someone does need access, ask them to use boards or a protected route, and remind them never to step on rooflights or fragile sheets.
