About our roof leak investigation in Coombe
Not every drip is a leak. In a badly ventilated roof space, condensation can form under the roof and drip, leaving marks that look just like rainwater. Telling the two apart matters, because they need very different work. The pattern of the damp, the ventilation and the timing all help us decide. We are often asked to look into water through the ceiling under a flat roof and damp on a chimney breast, on valleys and parapet gutters, chimney stacks and flat roof details.
Many London homes are well over a century old and their roofs have been patched more than once, 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 usually exclude wear and tear. A careful look in Coombe tells the two apart where the evidence allows. Photographs and a written account give you something specific to show an insurer, a landlord or a roofer.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

What we do, step by step
Photos are taken throughout the visit, so you can see in the report what we found and where. We take close-ups from wherever is safe. A typical visit takes an hour or two for a house, and about three to four hours for a commercial roof. In Coombe, as in much of London, a good many properties are flats or terraces without side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. If the building has a managing agent or access rules, tell us when you book.
- You tell us where the water appears, when, and what the weather was doing.
- Inside, we look at the stain and the ceiling around it.
- From the loft space, we trace the water’s route where there is safe access.
- We inspect the likely entry points outside, from the ground, windows and the roof where safe.
- We email a written report showing where the water most likely gets in.
Getting ready for the survey
- If it is not your property yet, arrange access through the agent
- Leave side gates unlocked
- For flats, check roof access has been agreed

Leave it or get it looked at?
A leak that returns after a repair usually means the real source wasn’t found. A careful investigation looks at every likely route, not just the obvious one. It gives the next repair a far better chance. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. By the time a ceiling stains, the timbers underneath may have been wet for a while.
A Basic Survey starts from £150, inc. VAT. Standard is from £250 and Premium from £400. We confirm the exact price before you book.

When to book a survey in Coombe
A gutter that overflows can soak a wall and mark the ceiling inside. Parapet and box gutters are the worst for this, since a blocked outlet sends water over the lining and into the building.
Here are some of the things we see frequently:
- Damp underlay across a wide area
- Brown rings on upstairs ceilings
- Water coming in around a roof light or dormer
- Wet patches high on an inside wall
Homes near green spaces like Cottenham Park can get more leaves in their gutters in autumn, so outlets and downpipes are worth watching.
Questions to ask before booking
- What happens after the report arrives
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Whether you get a written report with photos
- Their report turnaround times

Checking the roof from the ground
It helps to keep a record: dates of leaks, photos from the ground and any work done on the roof. Share it with us when you book, as it helps us focus the survey.
You can learn a lot from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
What a survey costs
What a survey costs depends on the time and equipment it needs. The main factors are:
- Extra roofs, like extensions, dormers or garages
- Building height and the viewpoints available
- The roof’s overall size
- Features like valleys, chimneys, dormers and parapets
Prices start from £150, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, with VAT included, and we’ll tell you which fits.
Booking your survey
If you can, have these to hand when you get in touch:
- The property’s address and postcode
- The style of property, from a terrace to a block
- Pictures of the roof from a safe spot, if you have them
- Anything about access we should know
A quick phone call is usually the easiest start: phone 07833 053749 or use the contact form and we’ll ask a few questions about the roof. The price is agreed before a date is set.
FAQs for Coombe
Does a conservation area affect roof work in Coombe?
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. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you carry out roof surveys in Coombe?
Yes, Coombe is within the area we cover. We work right across London and South East England. You can call 07833 053749 or drop us an email with the address and some details.
Can a leak be traced on a dry day?
Often, yes. Stains, tide marks, damp timbers and moisture readings typically point the way. Intermittent leaks can be harder, so photos and notes from when it leaks help a lot.
Does the report include photos?
Yes. The report includes photographs of what we found, so you can see exactly what each finding refers to.
How long does a roof leak investigation take?
On site, it normally takes about 1–2 hours at most homes, and about three to four hours for a commercial roof. The report follows within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
What’s the best way to book?
To book, call 07833 053749 or email us with the address, the type of property and what’s prompted the survey. We’ll confirm the price and find a day that suits.
Which days do you carry out surveys?

Coombe roofs and the weather
About 1.4 miles east lies Southside House, a reminder of how long the area around Coombe has been built on. 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. 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. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Different coverings let water in at different points, which shapes where the search starts.
If you own a rental within reach of Norbiton station, a tenant living with a leak needs the cause found, not just the stain painted over. The streets around a church like Christ Church New Malden are frequently among the oldest in a place, and if your house is among the older ones nearby, water on an older roof tends to find its way in at the lead, the valleys or the chimney.
