Flat roof survey in Crossness: what you get
Buying a home with a flat-roofed extension, dormer or garage? It is useful to know that roof’s condition before you exchange. Many felt roofs need renewing after around 15 to 20 years, and EPDM and GRP often go on for longer. We set out the type of covering, its condition and the defects we found, with photographs of each. That gives you facts to raise with the seller or agent. If you’re worried about standing water left after rain and cracked or split membrane, a survey will tell you what’s going on.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Each pipe, upstand and fixing through the covering is a possible weak point. In Crossness, roof access is agreed with the building manager or owner beforehand. Plant bases, rooflights and cable entries are all places where water can get in.
It isn’t only a list of defects. It explains what we found, why it matters and what we recommend, so you can decide what to do next.

When to book a survey in Crossness
Flat roofs take the full force of the weather on a surface that drains slowly. In time, the covering dries out, cracks and loosens at its edges and laps. People usually call us when a leak appears, before a purchase, or when the roof may be near the end of its life.
We’re frequently asked to look at:
- Outlets choked with leaves and silt
- Pools of water lying on the roof
- Damaged trims at the roof edge
- Gaps at upstands and abutments
For an older house near a landmark such as Church of the Cross, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
Choosing a roof surveyor

- Will the report include photos?
- Will they check the loft as well as the outside?
- Which limits apply to the survey
Why act early in Crossness
If you are buying, find out about the flat roof before you exchange. After that, the cost of any work is yours. Our report gives you specific points to raise with the seller or agent. In Crossness, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Finding it early keeps the work smaller.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before booking.

Can I check my roof myself?
Your own check is a good start, but it isn’t a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground.
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.

What a survey costs
When we price a survey, we consider:
- How tall the building is and how easy the roof is to see
- Extensions, dormers and garages with roofs of their own
- Any need for thermal images or a drone flight
- Features like valleys, chimneys, dormers and parapets
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Prices start from £150, including VAT.
Helping us price your survey
There is no need for technical words. It’s enough to let us know:
- What kind of property and roof it is
- Where the property is, with the postcode
- Where water is showing inside, if it is
- Pictures of the roof from a safe spot, if you have them
Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, call 07833 053749 or drop us an email with the address and the days you’d prefer.
Flat roof surveys in Crossness: local notes
Rainham Hall, about 2.8 miles north-east, is one of the historic houses in the wider area around Crossness. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. 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 businesses in and around places such as Gallions Reach Shopping Park, the flat roofs over shops and commercial units are worth checking before a leak, not after. Landlords with a home close to Abbey Wood station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.

How the survey changes by roof type
EPDM rubber
Lifting at the edges and loose areas of membrane are common EPDM problems. Any we find are noted and photographed.
Rooflights and upstands
Upstands at walls and parapets need to stay watertight as the building moves. We look for splits, gaps and failed flashings over the top.
What happens on the day
The visit has one job: to look at the flat roof as closely as is safe and record what we find. Everything we note and photograph goes into the written report. The visit normally takes about one to two hours for a house; commercial roofs usually need 3–4 hours. In Crossness, as in much of London, lots of properties are flats or terraces without side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. If the building has a managing agent or access rules, tell us when you book.
- 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.
Before the survey
- Make sure the loft hatch can be reached
- Mention any parking restrictions on your street
- If the roof is shared, arrange access with whoever manages the building

Advice
FAQs for Crossness
Is parking a problem for a survey in Crossness?
Typically it is manageable with a little notice. Let us know what parking is available nearby, and the visit is planned around it.
How do I find out if my home in Crossness is listed?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
Can you tell me how long my flat roof will last?
There’s no honest way to give an exact number of years. As a guide, felt often lasts around 15 to 20 years, EPDM frequently 30 to 50 and GRP up to about 30, but the report tells you how your roof is really doing.
Will you photograph what you find?
Yes. Photos are taken throughout the survey, and the report uses them to show each finding alongside our recommendations.
How much is a survey?
Prices start from £150, including VAT. The final figure depends on the roof and the package you choose, confirmed before anything is booked.
Do you go up onto the roof?
Only where it is safe to do so. If not, we use safe viewpoints and look inside, and we note any area we couldn’t see. We do not walk on fragile rooflights or sheeting.
Are you insured?
Our surveys are covered by professional indemnity and public liability insurance. Ask if you need details for a managing agent or building owner.
