Duckett's Green Roof Leak Investigation
A careful look at the leaking roof at your property in Duckett's Green, with photos and a written report.
- Damp ceilings under a flat roof
- Damp on a chimney breast

Honest limits
Some things cannot be seen without opening up the roof, so a survey has limits:
- A structural engineer’s report
- An intermittent leak that shows no trace on the day
- Defects hidden under coverings or inside walls without opening up

Roof leak investigations for homes and businesses in Duckett's Green
We investigate roof leaks in Duckett's Green and across London and South East England. Surveys are carried out on weekdays and at weekends. We look inside and out, at flashings, valleys, chimneys, gutters and flat roof details. You get a report with photographs and recommendations. If water is coming in now, catch it in a bucket and keep it away from lights and sockets, then call 07833 053749 or email us. We survey flat roof details, slate and tile slopes and lead flashings, and the problems we’re asked to look at most are leaks below a flat extension roof and brown rings on upstairs ceilings.
In converted houses and blocks across London, water from a roof can run a long way before it shows on a ceiling, sometimes in a different flat from the one below the defect. Tracing it back matters, both for dealing with the cause and for any insurance claim. We check what we are given access to in Duckett's Green, inside and out. It’s useful to know when the water appears and in what weather.
Where we can’t see part of the leaking roof, the report says so. You will know exactly what was inspected and what wasn’t.

Wind, rain and roofs in Duckett's Green
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. Each of these roof types has its own typical places for water to get in. Historic houses such as Bruce Castle, about 1.2 miles north-east, show how far back building in the area around Duckett's Green goes. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material.
Trees in and around Ducketts Common shed leaves that can end up in nearby gutters, and an overflowing gutter soon means a wet wall. For site and facilities teams at buildings like St John Vianney RC Primary School, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot. If your house is among the older ones in the streets near Christ Church, the leak may come from a chimney, a valley or tired lead rather than the covering itself.

How the survey changes by roof type
Slate and tile slopes
Cracked mortar lets ridge and hip tiles move. Water then gets in along the top of the roof.
Chimney stacks
Chimneys let water in through pointing, flaunching, flashings and open pots. Each is looked at from each safe vantage point, and look for damp on the breast inside.
Questions from Duckett's Green
Is Duckett's Green in the area you cover?
Yes, Duckett's Green is within the area we cover. We cover the whole of London and South East England. Just call 07833 053749 or use the contact form and let us know about the property.
Is my home in Duckett's Green listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Will I get photos?
Yes. Photos are part of every report, so you can see exactly what each finding refers to.
Which days do you carry out surveys?
Surveys can be booked for any day of the week: weekdays, Saturdays and Sundays. Just tell us the days that suit you.
Why isn’t the leak directly above the stain?
Because water travels. It runs along rafters, battens or underlay before it drips, so the stain may be some distance from where it gets in. That’s why we trace the route rather than patching above the stain.
What happens after the survey?
You’ll get the report by email, with photos and clear recommendations. With Standard there’s a follow-up consultation; with Premium, an in-person consultation, so you can talk the findings through.
Can you find a leak when it is not raining?
In many cases, yes. Stains, tide marks, damp timbers and moisture readings usually point the way. Some leaks only show in particular weather, so your photos and notes from wet days are very useful.
Checking the roof from ground level
A lot can be seen from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Don’t go up yourself.
Tips that help
Over many surveys, some simple habits stand out as worth the effort:
- Move stored items away from the hatch
- Let us know if there are tanks or pipes in the loft
- Keep a photo record of the damp patch
- Record whether it leaks in every downpour or only some
If there are several possible sources, we list them in order of likelihood. We say which items need prompt attention, so you know what to deal with first.
Keep the loft space ventilated. Air movement keeps condensation down, which is often mistaken for a leak. Check insulation doesn’t block airflow at the eaves.
The survey, step by step
Once we’ve finished looking, we write up our findings in a report with photos, emailed to you. As for time on site, it typically takes an hour or two on an ordinary house, with bigger or more complicated roofs taking longer. In a London area like Duckett's Green, the main things to sort out are parking and access: let us know about parking, the floor the property is on, any shared entrance and loft access. On the day, the roof is looked at from the ground, from windows, from inside the roof space and from the roof where it’s safe.
- You tell us where the water appears, when, and what the weather was doing.
- We examine the damp area and the rooms near it.
- From the roof space, we trace the water’s route where there’s safe access.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from every safe vantage point.
- You receive a report with the likely source, photos and recommendations.
Before we arrive
- Make sure the loft hatch can be reached
- For flats, make sure roof access has been agreed
- Check we can get to the back of the property
