Roof leak investigation in St Margarets: what you get
Leaks tend to begin where one part of a roof meets another. Flashings at chimneys and walls, valleys, gutters, parapets and flat roof upstands and outlets are the usual suspects. Each of these is checked in turn and follow the evidence. Chimneys, dormers and roof lights each add joints of their own. Each one is checked from wherever it’s safe to see it. We survey chimney stacks, the roof space and flat roof details, and people most often book us about water coming in around a roof light or dormer and ceiling stains that grow after rain.
Many London homes are well over a century old and their roofs have been patched more than once. Telling wear from a one-off event matters, because insurers usually exclude wear and tear. A careful look in St Margarets tells the two apart where the evidence allows. A written record with photographs helps you explain what was found to whoever deals with it next.
What you get is a clear record of the leaking roof on the day we saw it. That makes it useful now and a handy reference later, for instance when you want to check whether anything has changed.

Useful tips for St Margarets property owners
A little preparation and a few simple habits help, both for the survey and for the roof itself. Our tips:
- Move stored items away from the hatch
- Take dated photos of the leak
- Let us know what has already been tried
- Mention any plumbing above the damp area
The report gives whoever carries out the work a clear starting point. The photos show the defects and where they are, so the repair is aimed at the cause.
Check the loft after heavy rain, with care and a good torch. Look for drips, damp patches and stains on timbers. Photograph anything new.

The survey, step by step
Once we have finished looking, we write up our findings in a report with photos. On timing, most surveys take roughly 1–2 hours at a typical home, or half a day or so for a commercial building. In St Margarets, as in much of London, lots of properties are flats or terraces without side access, so the back of the roof is frequently seen from upstairs windows, from inside or, where a flight is allowed, from the air. Mention any building rules, key holders or managing agents as you book.
- You let us know where the water shows and when it appears.
- Inside, we check the damp area and the loft space above it.
- We check the likely entry points outside, like flashings, valleys, chimneys and gutters.
- Moisture readings and thermal imaging are used where they help.
- You receive a written report with photos showing the likely source and what needs attention.
Before the survey
- Have any questions written down, so nothing gets missed
- Keep pets out of the way during the survey
- Buyers: confirm access with the estate agent or seller
Getting a price
Our price is from £150, including VAT. What you pay depends on the roof’s size, access and the package, and you can ring 07833 053749 or email us to find out.
Advice
What we’re asked to look at in St Margarets
Slipped or missing slates and tiles let rain reach the underlay. 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.
A survey can pick up problems such as:
- Water through the ceiling under a flat roof
- Water coming in around a roof light or dormer
- Wet patches on loft insulation
- Damp patches next to the stack
For hotels and guest houses around St Margarets, a roof problem found early is far less disruptive than one found by a guest, so it is worth knowing the roof’s condition.
Before you book anyone
- Whether any drone flown is registered with the CAA
- Whether the loft is part of the inspection
- How much experience they have with roofs like yours
- Which parts of the roof they’ll actually see
St Margarets questions
Is St Margarets in the area you cover?
Yes, St Margarets is one of the places we work. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
How do I find out if my home in St Margarets 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.
Will you fly a drone over my roof?
Yes, where it applies and safe. We fly a sub-250g drone and we’re a CAA-registered drone operator (Flyer ID and Operator ID). Drone inspection is part of the Drone Roof Survey and the Premium Survey, where it applies.
Can you find a leak when it isn’t raining?
Usually, yes. Damp materials can be found without rain. For leaks that only happen in certain storms, we report the most likely routes.
Can every leak be traced?
Not always, and we will be honest about that. Water can travel a long way, and some leaks only show in particular storms. If we can’t be sure, the report ranks the possible sources.
Why is not the leak directly above the stain?
Water rarely drops straight down. It can follow a timber or the underlay a long way first, so the entry point is often well away from the mark. That is why we trace the route rather than patching above the stain.
Can you survey at the weekend?
We carry out surveys on any day of the week. To arrange a date, phone 07833 053749 or drop us an email.
Honest limits
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Carrying out the fix
- What’s under the covering or behind the plaster
- Water from pipes, tanks or heating systems

Roof leak investigations around St Margarets
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. If your home in St Margarets is one of them, bay roofs, hips and later dormers each have their own details. Where water gets in depends a good deal on what the roof is made of and how it’s detailed. Richmond House, about 1 mile south, is one of the historic houses in the wider area around St Margarets. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs.
Landlords with a home close to St Margarets (London) station may find that a tenant living with a leak needs the cause found, not just the stain painted over. Homes near green spaces such as Richmond Green can get more leaves in their gutters in autumn, and an overflowing gutter soon means a wet wall.

What happens if roof problems are left?
Wet insulation doesn’t insulate well. A slow leak can soak it for months before a stain appears. The sooner the cause is found, the less needs replacing. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. When the stain finally shows, the damage underneath is often older than it looks.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before booking.
