Roof leak investigation in Cheam
Our job is to find the likely source and tell you. You get a written report with photos showing the likely entry point and the route the water is taking, plus recommendations on what needs attention. Whoever does the work then has a clear starting point. We find and report the source, and the repair itself is a separate job. If you’ve noticed damp patches next to the stack and water dripping from rafters or underlay, we can find out what’s behind it.
In converted houses and blocks across London, water from a roof can run a long way before it shows on a ceiling. That makes the source hard to pin down, and finding it matters for whoever has to deal with it. We look at what we’re given access to in Cheam, inside and out. Let us know when the water shows, and in what kind of weather.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

Cheam roofs and the weather
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 Cheam is one of them, bay roofs, hips and later dormers each have their own details. Different coverings let water in at different points, which shapes where the search starts. Nonsuch Mansion, about 1 mile north-west, is one of the historic houses in the wider area around Cheam. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area.
If you live in an older home near Church of St Andrew, water on an older roof tends to find its way in at the lead, the valleys or the chimney. If you run a business near The Ashley Centre, a quick answer on where water is coming in keeps a business running. For landlords with property near Cheam station, tracing a leak quickly matters when a tenant is living with it.
Cheam is about 1 mile south-west of Sutton, in Greater London. Bookings from Cheam are handled just like any other: a call or an email, a price, then a date. Our area takes in places right across Greater London, from the larger towns to small villages. For surveys nearby, see our London page.
Surveys in SM2, SM3 and SM1 are booked the same way as anywhere else. We cover properties on Wray Road, York Road and The Avenue and the roads around them. Other places close to Cheam include Belmont (1 mile south-east), Cuddington (1 mile north-west), North Looe (1 mile south-west), North Cheam (2 miles north) and Nork (2 miles south). We also work in nearby towns such as London (12 miles north-east), City of Westminster (12 miles north), Marylebone (12 miles north), Kensington (11 miles north), St Pancras (13 miles north) and Shoreditch (14 miles north-east).
Landmarks near Cheam
Around Cheam, our work takes us to homes and buildings near Avenue Primary Academy, Howell Hill and Overton Grange School, among other places.

Green spaces nearby include Duppas Hill and Belmont Pastures.
The survey, step by step
Before we start, let us know why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. The visit typically takes an hour or two for most homes, though a hard-to-trace leak can take longer. London terraces rarely offer a view of the whole roof from one spot, so in Cheam we work round the house, using the street, the windows, the loft and any safe vantage point behind it. If other people live in the building, tell us who can let us into the shared parts.
- You get in touch with details of the leak and any photos.
- The visit starts indoors, at the stain and in the loft.
- Outside, we look at every likely route in.
- Where it helps, we take moisture readings and use thermal imaging.
- We email a report with photos, the likely entry point and recommendations.
Before the survey
- Clear the way to the loft hatch
- Make sure we can get to the back of the property
- If it isn’t your property yet, arrange access through the agent

DIY checks: what’s safe
During heavy rain, look at the gutters from the ground or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
Your own check is a good start, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight.
When you need someone else
Every survey has limits, and it’s better to know them up front. Keep these in mind:
- Whether rotten timbers meet design loads
- Putting the leak right
- Leaks that only appear in weather we cannot recreate
If you’re not sure which survey you need, call 07833 053749 or drop us an email and we will give you a straight answer. What our survey covers.
Roofs we survey in Cheam
- Valleys and parapet gutters
- Rooflights and dormers
- Lead flashings
- Flat roof details
- Slate and tile slopes

Cheam questions
Is parking a problem for a survey in Cheam?
Sometimes, yes. If Cheam has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
Does a conservation area affect roof work in Cheam?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you’re planning to re-roof in a different material.
Will I get photos?
Yes, plenty. Each finding is shown in a picture where possible, which makes the report easy to follow.
How fast do I get the report?
That depends on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. Reports are sent by email.
What happens after the survey?
The report arrives by email. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years.
How long will you be at the property?
The visit typically takes roughly 1–2 hours for a house, or half a day or so for a commercial building. We’ll confirm what to expect when we arrange the visit.

Tips that help
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Photograph the stain each time it appears
- Leave roof access to professionals
- Write down the wind direction and rain when it leaks
- Check whether pipes or tanks run near the stain
With the Standard Survey you get a follow-up consultation, and Premium includes an in-person consultation. You can ask us about anything that isn’t clear.
After a downpour, look in the loft space with a torch, keeping to boarded areas. Watch for water marks, wet underlay and damp wood. Take photos of anything that changes.
