Roof Survey in Blackfen
A roof condition survey for homes and buildings in Blackfen, using drones and thermal imaging where it applies. Call or email for a price.
- Torn or sagging underlay
- Leaking gutter joints and downpipes
- Worn lead at chimneys and abutments
Before and after the survey
You do not need to be a roofer to help. Here’s what helps most:
- Move stored items away from the loft hatch
- Leave roof access to professionals
- Include dormers, porches and garages when you book
- Tell us about any leaks or stains you’ve seen
Standard includes a follow-up consultation to talk the findings through, and the Premium Survey includes an in-person consultation. It is a chance to ask questions about anything in the report.
Do not block the vents at the eaves. A stuffy loft collects condensation, and it can wet timbers and insulation. Keep insulation clear of eaves vents.
Roof surveys for homes and businesses in Blackfen
Everything we check, we check safely: from ground level, from windows, from the loft space and from the roof where conditions allow. The Premium Survey adds thermal imaging and, where it applies, a drone, for roofs that are hard to see well. You do not need to do anything except give us access. Each defect we find is photographed and explained. We are often asked to look into ridge tiles that have lifted or moved and worn or blocked valleys, across lead flashings, natural slate and the roof space.
Victorian and Edwardian terraces are found right across London, often with slate roofs, chimney stacks shared with neighbours and gutters hidden behind parapets. Slates can last a century or more, but the nails holding them corrode, and slates slip. In Blackfen, as across London, that is why a roof needs a close look rather than a glance from the street. Shared chimney stacks and the lead around them are just as important to check.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

What a 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. About 1.2 miles east lies Danson House, a reminder of how long the area around Blackfen has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area.
For landlords with property near Falconwood station, a dated record of the roof is useful when planning maintenance across a let. Anyone responsible for a site like Our Lady of the Rosary Catholic Primary School will know that large buildings have long gutter runs and big roofs that need checking like any other.
Blackfen is about 2 miles east of Eltham, in Greater London. Houses, flats, blocks and commercial buildings in Blackfen can all book roof surveys. Blackfen is one of the places in Greater London we cover for roof surveys. Our London page covers surveys nearby.
Surveys in DA15, DA16 and SE9 work the same way as everywhere else we cover. We offer roof surveys to properties on Days Lane, Gordon Road and Kent Avenue. If you’re just outside Blackfen, we cover Falconwood (1 mile north), Avery Hill (1 mile west), East Wickham (1 mile north), New Eltham (1 mile south-west) and Longlands (1 mile south).

Landmarks near Blackfen
Locally, jobs take us to homes and businesses close to The George Staples pub, Harris Academy Falconwood and Shoulder of Mutton Green and the streets around them.

Not far away are Summer Hill and The Tarn.
Common roof problems in Blackfen
Some damage starts inside the loft space. A badly ventilated loft collects condensation, and the damp gets into timbers and insulation. It can look like a leak.
We are frequently asked to look at:
- Ponding, splits or blisters on flat roofs
- Ridge tiles that have lifted or moved
- Blocked, sagging or leaking gutters
- Loose chimney pots
Living close to Shoulder of Mutton Green is pleasant, but mature trees mean leaves in gutters and valleys each autumn, so outlets and downpipes are worth watching.
What to check before booking
- What’s outside the scope of the survey
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- Their report turnaround times
- Whether the roof space is looked at, where there is one
Should I look at the roof myself first?
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
What you can’t do safely is get up close. Roofs are fragile and slippery, and falls from height are serious. That is where a survey comes in.
What happens on the day
We work from the outside in: outside views come first, then the loft space if there’s safe access. All told, expect roughly 1–2 hours at most homes, or half a day or so for a commercial building. London terraces rarely offer a view of the whole roof from one spot, so a visit in Blackfen moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Tell us who holds the keys.
- We help you choose a Basic, Standard or Premium Survey.
- We arrive at the agreed time and talk through any concerns.
- We inspect and photograph every part of the roof we can safely see.
- Extra checks are carried out where your package includes them.
- You get a written report with photos and clear recommendations.
How to prepare
- Point out any leaks or damp patches
- Agree roof access with the managing agent if it’s shared
- Have any paperwork from past roof work to hand
Book a survey
If you have photos of the roof, send them over. Take them safely from ground level or a window; never climb up to get a better view. To send them or to book, call 07833 053749 or use the contact form.

Why act early in Blackfen
If you are planning to sell, a roof survey can help you prepare. You can deal with defects before a buyer’s surveyor finds them, or at least know what to expect. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. When the stain finally shows, the damage underneath is often older than it looks.
Prices start from £150, including VAT. Basic starts from £150, Standard from £250 and Premium from £400, VAT included, and we’ll tell you which fits.
Why book with us

Common questions in Blackfen
Do you survey roofs for landlords with property near Falconwood station?
Yes, rented property is part of what we cover. You can phone 07833 053749 or use the contact form with the address and some details.
Can you fly a drone over a roof in Blackfen?
It depends on the exact address and the weather on the day. 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. Across London there are restriction zones around Heathrow, London City and London Heliport, plus restricted areas over Hyde Park, the City of London and the Isle of Dogs. Each address is checked against all of them before the drone goes up. High wind or heavy rain also stops a small drone flying.
How soon is the report ready?
Premium reports arrive the same day, Standard within 24 to 48 hours and Basic within 48 hours. Each report includes photos.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years, across London and South East England.
What does a roof survey cost?
Our price is from £150, including VAT. The final figure depends on the roof and the package you choose.
Do you cover Blackfen?
Yes. Our area covers London and South East England, Blackfen included.
Does the weather affect the survey?
Light rain is normally fine; heavy rain and wind are different. In strong wind or a downpour, a drone can’t fly and access may not be safe, so we’d move the date with you.
Honest limits
We only report what can be seen safely on the day, so there are some things a survey can’t cover:
- A full building survey of the property
- An exact number of years the roof has left
- Faults hidden behind ceilings or boarding
