Manor House Roof Leak Investigation
Find out what’s going on with the leaking roof before you spend money on it. We carry out roof leak investigations in Manor House.
- Staining where a gutter or parapet meets the wall
- Water marks that spread in wet weather
- A leak that comes and goes with the weather
What happens on the day
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, including by drone where it’s applicable and the weather allows. A typical visit takes between one and two hours at a typical home, and more on a big or complicated roof. London terraces rarely offer a view of the whole roof from one spot, so in Manor House we work round the house, using the street, the windows, the loft and any safe vantage point behind it. If other people live in the building, let us know who can let us into the shared parts.
- 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.
How to prepare
- If you’re buying, let the agent know when we are coming
- For a flat or shared roof, check access with the building owner or managing agent
- Move anything stored under the loft hatch
How to book
Prices start from £150, including VAT. What you pay depends on the roof’s size, access and the package, and you can call 07833 053749 or use the contact form to find out.

Roof leak investigations for homes and businesses in Manor House
Roof leaks rarely show up where you’d expect. It can run along a rafter, a batten or the underlay before it drips, so the stain on your ceiling is seldom right under the hole. We follow it back towards where it starts. A repair aimed only at the stain can miss the cause entirely. Finding the route first lets the repair go where it’s needed. If you are worried about water marks that spread in wet weather and wet patches high on an inside wall, we can find out what’s behind it, on lead flashings, slate and tile slopes and flat roof details alike.
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 typically exclude wear and tear. That’s as true in Manor House as anywhere in London. A written record with photographs helps you explain what was found to whoever deals with it next.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

Roof leak investigations in Manor House: local notes
The wider area around Manor House has a long history of building, with Bruce Castle about 2.1 miles north-east. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, 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. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. Different coverings let water in at different points, which shapes where the search starts.
If you run a business near The Mall Wood Green, a leak can close part of a shop or office, so finding the cause quickly matters. If you let a flat or house near Harringay Green Lanes station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused. Living close to Chestnuts Park is pleasant, but mature trees mean leaves in gutters and valleys each autumn, so outlets and downpipes are worth watching.

DIY checks: what’s safe
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Do not go up yourself.
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
Your questions about roof leak investigations in Manor House
Do you cover Manor House?
Yes. Our area covers London and the South East, and Manor House is part of that. Just ring 07833 053749 or use the contact form and let us know about the property.
Can parking be tricky for a visit in Manor House?
It depends on the street. If Manor House has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
How do you tell a leak from condensation?
The two can look alike. Widespread damp on the underside of the roof in cold weather, with blocked vents, suggests condensation. We check the pattern of damp and the ventilation, then say which is most likely.
Are you structural engineers?
No. We are roof surveyors, not structural engineers. We will recommend an engineer if we see signs that call for one.
How experienced are you?
More than 5,000 surveys over 20+ years.
Does the investigation include the repair?
Our job here is to trace the leak and explain it, not to carry out the repair. The report gives any roofer a clear brief.
Why doesn’t the damp patch line up with the hole?
Rain that gets in will run along whatever it lands on. On a flat roof it can travel under the covering before it finds a way through the ceiling. Tracing that path is the heart of a leak investigation.
How the survey changes by roof type
Parapet and box gutters
Hidden gutters run behind parapets or between roofs. When their outlets block, water rises over the lining and runs indoors.
Flat roof upstands and outlets
Upstands seal the edge of a flat roof where it meets a wall. If it’s too low, cracked or poorly dressed, water gets behind it.
What we cannot see
Some things can’t be seen without opening up the roof, and that sets some limits:
- Leaks from plumbing, tanks or pipework rather than the roof
- Whether rotten timbers meet design loads
- An intermittent leak that shows no trace on the day
If in doubt, phone 07833 053749 or use the contact form and we will point you to the right survey before you book. What our survey covers.
Roofs we survey in Manor House
- Rooflights and dormers
- Flat roof details
- Chimney stacks
- Slate and tile slopes
- Valleys and parapet gutters
- The roof space
- Lead flashings
Leave it or get it looked at?
Wet insulation doesn’t insulate well. Insulation can soak up water quietly before anything shows below. Catching it early limits what has to be replaced. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. By the time a ceiling stains, the timbers underneath may have been wet for a while.
