How a pre-purchase roof survey works in Blackfen
Buyers in Blackfen and right across London and the South East use our pre-purchase roof survey. From terraced and semi-detached homes to detached houses and flats, the roof gets the same careful look. The report says what’s in good order, what is not and what to deal with first. We hold professional indemnity and public liability insurance, and have 20+ years’ experience. To arrange a survey, phone 07833 053749 or email us. Common reasons to book are quick fixes on flashings and valleys and chimney mortar that has eroded, on the roof space, gutters and downpipes and natural slate.
In a London terrace or conversion, the roof frequently joins the neighbours’ roofs and shares their stacks and gutters, with parapet walls and party-wall upstands marking where one roof ends and the next begins. That matters for anyone buying in Blackfen or checking a new roof there: only the parts we are given access to and can see safely are inspected. If it is a flat, the lease normally sets out who is responsible for the roof.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

Questions from Blackfen
Can parking be tricky for a visit in Blackfen?
Parking in Blackfen, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Are there drone restrictions around Blackfen?
That depends on where the roof is and on the weather. The flight restriction zone around London City Airport comes within about 2 miles of Blackfen. We check the exact boundary for the address before flying, and if the roof falls inside it, we ask for permission first. London’s airspace includes flight restriction zones around Heathrow, London City Airport and London Heliport, and restricted areas over Hyde Park, the City of London and the Isle of Dogs. Every London address is checked against them before a flight. The flight also waits for calm, dry weather.
Do I have to be there for the survey?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in.
Do you carry professional indemnity insurance?
We hold professional indemnity and public liability insurance, for every survey we carry out.
How soon is the report ready?
It depends on the package: Basic within 48 hours, Standard within 24 to 48 hours and Premium the same day. Let us know your timetable when booking.
Can you survey a shared roof?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we’re allowed to reach, and the report makes that clear.
When is the best time to have the roof checked when buying?
The sooner after your offer is accepted, the better. The report is most useful before exchange, while you can still ask questions and negotiate.
What a survey costs
To price your survey, we check:
- The height of the building and how the roof can safely be seen
- Extra roofs, like extensions, dormers or garages
- How complicated the roof is, with its valleys, chimneys and parapets
- Whether you choose the Basic, Standard or Premium Survey
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You’ll know the figure before booking.
Booking your survey
When you call or email, these details help:
- Your postcode, so we can check access and travel
- Where water is showing inside, if it is
- The kind of building and roof involved
- Whether there’s a loft hatch, a shared roof or tricky access
Prices start from £150, including VAT. What you pay depends on the roof’s size, access and the package, so ring 07833 053749 or use the contact form with the details.
The survey, step by step
Once we’ve finished looking, we write up our findings as a written report with photos, sent to you by email. On timing, most surveys take an hour or two at the house you’re buying, depending on its size and how much of the roof can be seen. In Blackfen, as in much of London, lots of properties are flats or terraces without side access, so the back of the roof is frequently 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.
- Once your offer has been accepted, you book and give us the address and your timescale.
- Access is arranged through you, the agent or the seller.
- The roof is inspected from every safe viewpoint, inside and out.
- Coverings, ridges, valleys, flashings, chimneys and gutters are checked and photographed.
- You receive a written report with photos and recommendations to read before exchange.
Getting ready for the survey
- Unlock side gates and any roof access doors
- Buyers: confirm access with the estate agent or seller
- Show us where any leaks or stains appear
How to book
Most bookings start with a short call: ring 07833 053749 or drop us an email and we will ask a few questions about the roof. You will have a price before anything is arranged.

Landlords, agents and block managers in Blackfen
Managing agents and residents’ management companies use roof surveys to plan maintenance. The report sets out what needs attention now and what can wait, which helps with budgets and planning.
With a portfolio of properties, you can book surveys for several addresses. To discuss a number of properties, ring 07833 053749 or use the contact form with the addresses.
Before and after the survey
These tips come from what we see on roofs every week:
- Request records of any re-roofing
- Don’t leave it until just before exchange
- Look for fresh paint on upstairs ceilings at viewings
- Let us know your timetable
With Standard, you get a follow-up consultation, and the Premium Survey includes an in-person consultation. If anything in the report isn’t clear, ask us.
Every so often, check the loft with a torch, keeping to boarded areas. Watch for stains, damp timbers and chinks of daylight. Take photos so you can show whoever looks at it.
What a pre-purchase roof survey looks like in Blackfen
The flight restriction zone around London City Airport comes within about 2 miles of Blackfen. If the drone is used for your survey, the exact boundary is checked for the address first. With Danson House about 1.2 miles east, Blackfen sits in an area with a long building history. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area.
Parking in Blackfen, as in most of London, takes a little planning: tell us about permits, visitor bays or off-street space as you book, as a space near the door cannot be promised. For landlords with property near Falconwood station, a written report helps before buying a rental or paying for a new roof on one. Take an older house close to Church of the Good Shepherd: the roof’s history matters as much as its looks, and a survey brings the past repairs to light.
Blackfen is about 2 miles east of Eltham, in Greater London. In Blackfen, as across Greater London, every roof gets the same careful survey. Blackfen is one of the places in Greater London we cover for pre-purchase roof surveys. Our London page covers surveys nearby.
We work across the DA15, DA16 and SE9 postcode area for pre-purchase roof surveys and the streets around it.

What happens if roof problems are left?
Even if you go ahead regardless, knowing the roof’s condition helps you plan. The report shows what needs doing first, so you can plan work before small faults get bigger. In Blackfen, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: failed flashings and blocked valley gutters can send water into more than one home. Finding it early keeps the work smaller.
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. Pre-purchase roof survey starts from £150, including VAT.

Roof by roof
Gutters and parapets
Hidden gutters behind parapets send water indoors when they block. Where we can see them safely, we check the linings and outlets.
Flat roofs
Flat roofs on extensions, dormers and garages are easy to forget about. Felt roofs often last around 15 to 20 years, rubber longer and GRP up to about 30. We check how the covering is wearing.
