How a roof leak investigation works in Denmark Hill
Moisture readings and thermal imaging are used where they’re useful. Moisture detection confirms where timbers, plaster or insulation are damp. Thermal imaging shows temperature differences that can point to wet areas, not water itself, so we confirm what it suggests with moisture readings. Thermal imaging is part of the Premium Survey, and moisture detection comes with Standard. The best thermal results come after a sunny day, with a dry roof and little wind. If you’re worried about wet patches on loft insulation and leaks at a dormer or roof window, a survey will tell you what’s going on, whatever the roof.
In a London flat, water can travel some way before it shows. That makes the source hard to pin down, and finding it matters for whoever has to deal with it. In Denmark Hill, we inspect what we can reach safely and are given access to. Tell us when the water shows, and in what kind of weather.
The written findings come by email, ready to forward to whoever needs them. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

For landlords and managing agents
An agent can book and manage the survey for a landlord, with the report sent to whoever needs it. We agree a time with the tenant beforehand.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, with the most urgent items set out first.
Different roofs, different checks
Parapet and box gutters
Parapet and box gutters sit behind walls or inside the roof. A blocked outlet sends water over the lining and into the building.
Chimney stacks
Water that gets in at the top can show up lower down. Unused flues with open pots can let rain straight in.
The survey, step by step
Every roof is different, but as a rough guide the survey takes roughly 1–2 hours for a house, or half a day or so for a commercial building. If you have questions on the day, just ask. Many London properties are flats or terraces with no 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, let us know when you book.
- You get in touch with details of the leak and any photos.
- We check the stain, the ceiling and the loft above it.
- We check the likely entry points outside, such as flashings, valleys, chimneys and gutters.
- Where it helps, we take moisture readings and use thermal imaging.
- Your report sets out where the water is most likely getting in, with photos and recommendations.
Before the survey
- Keep pets in another room
- If it is not your property yet, arrange access through the agent
- Find any records of previous roof work
Book a survey
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. For any other survey, just phone 07833 053749 or email us when you are ready.

What affects the price in Denmark Hill
We confirm the price for your roof before booking. This is what makes a difference:
- The size of the roof
- Extra roofs, like extensions, dormers or garages
- Any need for thermal images or a drone flight
- Chimneys, valleys, parapets and other details
Price depends partly on the package: from £150 for Basic, £250 for Standard and £400 for Premium, with VAT included. Size, height and access can affect the price too.
Getting in touch
To price your survey accurately, we’ll ask about:
- The style of property, from a terrace to a block
- Any stains, drips or damp patches you’ve seen indoors
- Whether there is a loft hatch, a shared roof or tricky access
- Your postcode, so we can check access and travel
Photos help, if you have them. Take them safely from the ground or a window, and please don’t climb up for a closer look. To get started, phone 07833 053749 or use the contact form.

Tips that help
A survey works best with a little help from you, before and after. Some tips:
- Photograph the stain each time it appears
- Mention earlier attempts to fix the leak
- Let us know if there are tanks or pipes in the loft
- Put a bucket under the drip and move valuables
Once the work is done, hold on to the report. If the leak returns, it’s a useful record of what was found, which makes the next step quicker.
After a storm, check the roof from the garden and the street. Pieces of slate or tile in the garden mean something has moved. Prompt repairs stop gaps turning into leaks.
Why get it checked now?
Leaks tend to get worse, not better. Wind lifts loose slates further and gaps widen. An investigation now gives you time to plan the work. In Denmark Hill, 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. Dealing with it early is far less disruptive.
Every price we give includes VAT, and the report isn’t charged as an extra. Roof leak investigation starts from £150, including VAT. Where your roof sits in the range depends on its size, height and access.

Wind, rain and roofs in Denmark Hill
The wider area around Denmark Hill has a long history of building, with Kingswood House about 2.6 miles south. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material. Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Different coverings let water in at different points, which shapes where the search starts.
For an older house near a landmark such as St Matthew's Camberwell, old mortar, worn lead and slipped slates are the usual suspects when water gets in. Homes near green spaces such as Brunswick Park can get more leaves in their gutters in autumn, so outlets and downpipes are worth watching. For businesses in and around places such as Surrey Quays Shopping Centre, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.

Common questions in Denmark Hill
How do I find out if my home in Denmark Hill is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Is parking a problem for a survey in Denmark Hill?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when booking.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and testing are not part of what we do. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them, and recommend a specialist asbestos surveyor checks them before they’re disturbed.
What happens next?
You’ll receive the report by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
Will you fly a drone over my roof?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.
Why doesn’t the damp patch line up with the hole?
Because water travels. It can follow a timber or the underlay a long way first, so the stain may be some distance from where it gets in. We follow the route back instead of guessing.
What insurance do you have?
Every survey is covered by professional indemnity and public liability insurance, and we can provide details if a managing agent needs them.
