Fortune Green: your questions answered
Is parking a problem for a survey in Fortune Green?
London parking needs a little planning, so let us know about permits, bays or a driveway when booking. That way the visit can be planned around it.
Is Fortune Green in the area you cover?
Yes. Our area covers London and South East England, and Fortune Green is part of that. Just ring 07833 053749 or use the contact form and let us know about the property, and we will talk through which survey suits.
Will you fix the leak as part of this?
This service finds and reports the cause, not to carry out the repair. The report gives any roofer a clear brief.
Do you survey roofs on blocks of flats?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we are allowed to reach, and the report makes that clear.
Will you fly a drone over my roof?
Yes, where it’s applicable. 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.
How many surveys have you done?
We’ve completed more than 5,000 surveys, over more than 20 years, and 98% of customers are satisfied.
Can thermal imaging help find my roof leak?
It can, when the conditions are right. The best results come after a sunny day, on a dry roof with little wind. Damp areas can hold heat differently from dry ones. Its findings are confirmed with a moisture check.
About our roof leak investigation in Fortune Green
A leak that comes and goes can be the hardest to pin down. Wind-driven rain, an overflowing gutter or snow melt may be what triggers it. Telling us when it happens helps a lot and so do photos. Even on a dry day, a leak typically leaves clues: stained timbers, tide marks and damp underlay. Moisture detection shows which materials are still damp. If you’re worried about leaks at a dormer or roof window and damp underlay across a wide area, a survey will tell you what’s going on.
Water getting into a London home often comes from a detail you cannot see from the street: the valley gutter in a butterfly roof, a parapet gutter, a chimney flashing or the flat roof over a rear extension. Whether you’re tracing a leak or recording storm damage in Fortune Green, those are among the first places to look. Water from a hidden gutter can run along joists and show up a room or two away.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

Why it is worth a survey now in Fortune Green
A leak rarely stays small. Damp spreads into rafters, ceilings and insulation. Tracing it now means less to put right later. In Fortune Green, 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. Finding it early keeps the work smaller.

Roof leak investigations around Fortune Green
Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. 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. Each of these roof types has its own typical places for water to get in. With Fenton House about 0.7 miles east, Fortune Green sits in an area with a long building history. 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.
Anyone responsible for a site like St Luke's Church of England School will know that a leak through a large roof is frequently found some distance from where the water shows inside. Living close to Kilburn Grange Park is pleasant, but mature trees mean leaves in gutters and valleys each autumn, so outlets and downpipes are worth watching.

Where a roof is shared: access has to be agreed with whoever owns or manages the building. Mention it when you contact us and we will plan the survey around it.
Buyers’ agents can book surveys on behalf of their clients. The report is emailed, so it can go straight to your client, photos included.
Can I check my roof myself?
A DIY look is useful, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from ground level.
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Do you need a roof leak investigation in Fortune Green?
When a slate slips or a tile cracks, the underlay takes the water. Ageing felt underlay eventually tears and lets water through, while some very old roofs have nothing under the coverings. On slate roofs, slipping is often caused by corroded nails.
We’re often asked to look at:
- Water marks that spread in wet weather
- Damp patches next to the stack
- Stains around a skylight
- Drips from nail tips in a cold loft
The streets around a church such as Church of St Luke are often 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.
Before booking any roof surveyor
- How they plan to inspect the roof safely
- Whether the loft space is looked at, where there is one
- What experience they bring
- Whether you can ask questions once you have the report
Places near Fortune Green
What else we do in Fortune Green
How the survey changes by roof type
Parapet and box gutters
Hidden gutters run behind parapets or between roofs. A blocked outlet sends water over the lining and into the building.
Slate and tile slopes
Ridge and hip tiles can loosen as their mortar cracks. Rain can then run in at the ridge.
What happens on the day
The visit has one job: to see as much of the leaking roof as can be seen safely and record it clearly. Notes and photos go into the written report. The visit typically takes about one to two hours for most homes, though a hard-to-trace leak can take longer. From the street, a London terrace normally shows only its front slope or parapet, so in Fortune Green we work round the house, using the street, the windows, the loft and any safe vantage point behind it. Shared stairs or a basement flat? Let us know who holds the keys.
- 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 roof space, we trace the water’s route where there is safe access.
- We inspect the likely entry points outside, from ground level, windows and the roof where safe.
- We email a written report showing where the water most likely gets in.
Getting ready for the survey
- Leave side gates unlocked
- Show us where any leaks or stains appear
- If the roof is shared, arrange access with whoever manages the building
