For landlords and managing agents
A roof problem in a let property affects your tenants as well as the building. A survey helps you spot issues early and plan the work around your tenants.
Letting agents frequently book on a landlord’s behalf, and the report can go to both. Access is agreed with the tenant ahead of time.
How a roof leak investigation works in Stonebridge
Moisture readings and thermal imaging are used where they’re useful. Moisture detection confirms where timbers, plaster or insulation are damp. A thermal camera shows patterns of temperature rather than water, so we confirm what it suggests with moisture readings. Thermal imaging is part of the Premium Survey, and moisture detection comes with Standard. Thermal imaging works best after a sunny day, on a dry roof with little wind. If you are worried about damp ceilings under a flat roof and damp on a chimney breast, a survey will tell you what’s going on, on lead flashings, rooflights and dormers and chimney stacks alike.
In London, leaks often start somewhere hidden: the valley gutter in a butterfly roof, a parapet gutter, a chimney flashing or the flat roof over a rear extension. Whether you are tracing a leak or recording storm damage in Stonebridge, 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.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

Tips that help
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Take dated photos of the leak
- Don’t touch fittings that water is reaching
- Record whether it leaks in every downpour or only some
- Check the loft is accessible
Your report arrives by email. It sets out where we believe the water is getting in, how it’s travelling and what needs attention. Turnaround is within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
After a storm, check the roof from the garden and the street. Pieces of slate or tile in the garden mean something has moved. Small faults dealt with quickly rarely become leaks.

What we look for on each type of roof
Lead flashings
Wherever a roof meets a wall or stack, a flashing keeps rain out. Lifted, split or slipped lead is a common cause, and for flashings that have been patched with bitumen.
Chimney stacks
A stack has several possible ways in for rain. We check each one as far as we can safely see.
What we are asked to look at in Stonebridge
Chimneys can let water in by several routes. Eroded pointing, cracked flaunching, failed flashings and open pots can all be responsible. It can show up on the chimney breast, nearby ceilings or in the loft space.
Things that frequently lead to a survey include:
- Leaks that appear only in driving rain
- Water dripping from rafters or underlay
- Damp on a chimney breast
- Staining where a gutter or parapet meets the wall
Anyone responsible for a site like The Stonebridge School will know that a leak through a large roof is frequently found some distance from where the water shows inside.

What a roof leak investigation looks like in Stonebridge
Historic houses such as Pitzhanger Manor, about 2.8 miles south-west, show how far back building in the area around Stonebridge goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first. Outer London has a good many Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, frequently with hipped roofs in clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Where water gets in depends a good deal on what the roof is made of and how it’s detailed.
If you own one of the older houses in the streets near Saint Michael and All Angels, the leak may come from a chimney, a valley or tired lead rather than the covering itself. Shop and office owners around London Designer Outlet may find that a quick answer on where water is coming in keeps a business running.

What happens on the day
A survey visit follows a simple order: we listen to what’s been worrying you, inspect the roof from each safe vantage point, take photographs as we go and record our findings for the written report. Most visits take about one to two hours for a house, though large, tall or awkward roofs take more time. For a visit in Stonebridge, parking and access are the things to plan: let us know about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at whatever is safely visible from ground level, windows, the loft and, where it is safe, the roof itself.
- You tell us where the water appears, when, and what the weather was doing.
- We examine the damp area and the rooms near it.
- In the loft, we follow any signs of water back towards the roof.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from each safe vantage point.
- We email a written report showing where the water most likely gets in.
Preparing for the visit
- Leave side gates unlocked
- Point out any leaks or damp patches
- Make sure pets are kept safely away

FAQs for Stonebridge
How do I find out if my home in Stonebridge is listed?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Do you cover Stonebridge?
Yes. We survey roofs across London and the South East, and Stonebridge is part of that. You can call 07833 053749 or send us an email with the address and a few details.
Can you always find the source?
Not every leak can be pinned down in a single visit. Most leave clues we can follow, but intermittent leaks that need particular weather can be harder. The report sets out what we found and the most likely routes.
What will the report tell me?
It works through the roof part by part, in writing and with photos, finishing with recommendations. The most urgent items are made clear.
Can a leak be traced on a dry day?
Often, yes. Stains, tide marks, damp timbers and moisture readings normally point the way. Some leaks only show in particular weather, so your photos and notes from wet days are very useful.
Will you walk on the roof?
Not unless it’s safe. Safe viewpoints, the roof space and a drone where applicable cover most of what’s needed, and the report notes anything we couldn’t see.
Will you fix the leak as part of this?
A leak investigation finds and reports the likely source. The repair isn’t part of it. The report shows where the water gets in and what should be done.
Why get it checked now?
A leak near lights or wiring needs attention quickly. If water is reaching a light fitting or switch, keep clear of it. Finding where the water is getting in should follow straight away. In Stonebridge, as across London, an overflowing gutter soaks the wall below, which can lead to damp inside. A small blockage left for a few winters becomes a damp problem.
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package you pick makes a difference too. The price is always agreed first.
