How a roof leak investigation works in Sands End
Flat roofs leak in their own ways. Splits, blisters, failed laps, worn upstands and blocked outlets are common causes. Ponding water makes any weakness worse. We check both the covering and the room underneath. Leaks under flat extension, garage and dormer roofs are common. Felt often lasts around 15 to 20 years, so age is part of the picture. If you’re worried about leaks that appear only in driving rain and ceiling stains that grow after rain, a survey will tell you what’s going on.
In a London flat, water can travel some way before it shows, 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. In Sands End, we inspect what we can reach safely and are given access to. Let us know when the water shows, and in what kind of weather.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

Signs you need a roof leak investigation in Sands End
A gutter that overflows can soak a wall and mark the ceiling inside. Parapet and box gutters are the worst for this, since a blocked outlet sends water over the lining and into the building.
Here are some of the things we see often:
- Damp on a chimney breast
- Water through the ceiling under a flat roof
- Drips in the loft during heavy rain
- Leaks that appear only in driving rain
Shop and office owners around Southside Wandsworth may find that a leak can close part of a shop or office, so finding the cause quickly matters.
Questions to ask before you book
- Will they check the loft as well as the outside?
- Whether they hold professional indemnity and public liability insurance
- Which limits apply to the survey
- When you will get the report

The survey, step by step
Photographs are taken throughout the visit, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available. Most surveys take about 1–2 hours, more where the leak is intermittent or the roof is large. In Sands End, visits are available on weekdays and at weekends. London parking is frequently by permit or pay-and-display, so it helps to know what’s near you. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- 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 loft space, we trace the water’s route where there’s 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.
Before we arrive
- For flats, make sure roof access has been agreed
- Find any records of previous roof work
- Make a note of anything you’d like us to look at
Book a survey

Roof by roof
Flat roof upstands and outlets
Upstands seal the edge of a flat roof where it meets a wall. A low or cracked upstand is a common way in.
Parapet and box gutters
We check the linings, joints and outlets where we can see them safely.
What a roof leak investigation looks like in Sands End
About 0.9 miles north-east lies Carlyle's House, a reminder of how long the area around Sands End has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. Many homes in inner London are Victorian and Edwardian terraces, frequently with Welsh slate roofs. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. 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.
Landlords with a home close to Imperial Wharf 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 Imperial Park can get more leaves in their gutters in autumn.

Common questions in Sands End
Is my home in Sands End listed or in a conservation area?
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.
Can parking be tricky for a visit in Sands End?
It depends on the street. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well.
Do I have to be there for the survey?
Not necessarily. If we only need the outside, we can agree that beforehand, but the loft and any rooms with damp need someone to let us in.
Does the report include photos?
Yes, every report has them. Each finding is shown in a picture where possible, which makes the report easy to follow.
Does this replace a RICS home survey?
No. This is a survey of the roof only, and it is not a RICS Level 2 or Level 3 survey. Many buyers have both.
What happens after the survey?
We email you the written report with photos and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Why does not the damp patch line up with the hole?
Water follows the easiest path, not the shortest. 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.
What this survey cannot tell you
Before you book, it’s worth knowing what a survey will not do:
- Carrying out the fix
- Leaks that only appear in weather we can’t recreate
- Water from pipes, tanks or heating systems
If in doubt, ring 07833 053749 or send us an email and we’ll suggest the right survey before booking. The full list of what we check.

Tips from our surveys
There is plenty you can do without going near the roof. Here’s what helps most:
- Move stored items away from the hatch
- Have an electrician check any wet fittings
- Note the weather when the leak shows
- Do not climb onto the roof to look
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.
Look at the roof from ground level after strong winds. Slipped slates, lifted ridge tiles and debris on the ground are signs to act on. Small faults dealt with quickly rarely become leaks.
