Roof leak investigation in Blackheath
Our job is to find the likely source and tell you. You get a written report with photographs showing the likely entry point and the route the water is taking, and recommends what should be done. Whoever does the work then has a clear starting point. We find and report the source, and the repair itself is a separate job. If you’re worried about water coming in around a roof light or dormer and brown rings on upstairs ceilings, we can find out what’s behind it.
London’s Victorian and Edwardian roofs have often been repaired many times, so a new leak can be the latest sign of wear rather than a single event. Telling wear from a one-off event matters, because insurers typically exclude wear and tear. A careful look in Blackheath tells the two apart where the evidence allows. Photos and a written account give you something specific to show an insurer, a landlord or a roofer.
Nothing in the report is left vague: if work is needed, the report says so clearly, along with how urgent it is.

How it works
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. All told, expect an hour or two at a typical home, or half a day or so for a commercial building. In a London area like Blackheath, the main things to sort out are parking and access: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. On the day, the roof is looked at from ground level, from windows, from inside the roof space and from the roof where it’s safe.
- We help you choose the package that suits the leak.
- A visit is booked for a weekday, Saturday or Sunday.
- We inspect inside and out, starting from the stain.
- Where it is useful and included, we take moisture readings and use thermal imaging.
- The report explains the likely entry point and what needs attention.
Before the survey
- Check the loft hatch can be reached
- Find any records of previous roof work
- Show us where any leaks or stains appear

What else we do in Blackheath
Checking the roof from ground level
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us when you book and it will help the survey.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
Do you need a roof leak investigation in Blackheath?
Blocked gutters can look like a roof leak. Hidden gutters behind parapets cause the most trouble, since a blocked outlet sends water over the lining and into the building.
These are some of the problems a survey can pick up:
- Drips in the loft during heavy rain
- Staining around the chimney inside
- Leaks that appear only in driving rain
- Brown rings on upstairs ceilings
Anyone responsible for a site like All Saints' Church of England Primary School Blackheath will know that water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.
What to check before booking
- Whether the loft space is looked at, where there is one
- How long they’ve been surveying roofs
- What the survey will not cover
- What exactly goes into their report
Leave it or get it looked at?
Guesswork repairs are a common reason leaks keep coming back. Because water travels, the real entry point may be somewhere else. We find the probable source before anyone starts work. In Blackheath, 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. Dealing with it early is far less disruptive.
For a price for your roof in Blackheath, phone 07833 053749 or drop us an email with the address and a few details. We will confirm the figure before booking.
What you get with us

Blackheath questions
Is parking a problem for a survey in Blackheath?
Sometimes, yes. If Blackheath has controlled parking where you are, a visitor permit is the easiest answer.
How do I find out if my home in Blackheath is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Is it a leak or condensation?
Many apparent leaks turn out to be condensation. A leak usually shows in one area and follows rain, while condensation is often spread out and worse in cold weather. We tell you which it is most likely to be.
Do you use drones?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.
Do you survey roofs on blocks of flats?
Yes, once access has been agreed. Roofs over flats are frequently shared, so the freeholder or managing agent needs to agree access. We can only inspect what we’re given access to.
Is it a structural engineer’s report?
No. Visible signs such as deflection or sagging are recorded, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
Which days do you carry out surveys?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Tell us which days suit you as you book.
What a roof leak investigation looks like in Blackheath
Many homes in inner London are Victorian and Edwardian terraces, often with Welsh slate roofs. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Knowing the roof type helps narrow down where water may be getting in. The wider area around Blackheath has a long history of building, with Queen's House about 0.9 miles north-west. 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.
Living close to Manor House Gardens is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and an overflowing gutter soon means a wet wall. The streets around a church such as Church of All Saints are often among the oldest in a place, and if your home is one of the older ones nearby, lead flashings, valleys and old chimneys are typical places for water to get in.
Blackheath is about 1 mile south-east of Greenwich, in Greater London. Blackheath gets the same service as everywhere else we work: a close look at everything that’s safely in view, photographs and a clear written report. Our area takes in places right across Greater London.

Useful tips for Blackheath property owners
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Make sure the loft is accessible
- Photograph the stain each time it appears
- Catch drips in a bucket and protect the floor
- Check whether pipes or tanks run near the stain
With the Standard Survey you get a follow-up consultation, and Premium includes an in-person consultation. You can ask us about anything that is not clear.
Keep the loft space ventilated. Good airflow reduces condensation, and condensation is a common false alarm. Make sure insulation does not block airflow at the eaves.
