Useful tips for Mitcham property owners
Nothing here needs a ladder. Our suggestions:
- Move stored items away from the hatch
- Check whether pipes or tanks run near the stain
- Have an electrician check any wet fittings
- Let us know what has already been tried
We email the report to you, with photos of what we found. It explains the likely entry point, the route the water takes and our recommendations. Basic reports come within 48 hours, Standard within 24 to 48 hours and Premium the same day.
After a downpour, look in the loft space with a torch, keeping to boarded areas. Look for drips, damp patches and stains on timbers. Take photos of anything that changes.
About our roof leak investigation in Mitcham
Roof leaks rarely show up where you’d expect. Water often travels along timbers or underlay before it finds a way down, so a ceiling stain is rarely directly below the cause. Our leak investigation traces it back. A repair aimed only at the stain can miss the cause entirely. Finding the route first lets the repair go where it’s needed. Common reasons to book are staining where a gutter or parapet meets the wall and ceiling stains that grow after rain, across chimney stacks, the roof space and flat roof details.
Many London homes are well over a century old and their roofs have been patched more than once, so a new leak can be the latest sign of wear rather than a single event. Telling wear from a one-off event matters, because insurers typically exclude wear and tear. That is as true in Mitcham as anywhere in London. Photos and a written account give you something specific to show an insurer, a landlord or a roofer.
The report records the leaking roof as we found it on the day. That makes it useful now and a handy reference later, for example when you want to check whether anything has changed.

Mitcham: your questions answered
How do I find out if my home in Mitcham is listed?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Do you cover Mitcham?
Yes. We work right across London and the South East, and Mitcham is part of that. Just phone 07833 053749 or send us an email and let us know about the property.
What does a roof survey cost?
Our price is from £150, including VAT. You’ll know the price for your survey before booking, and it depends on the roof’s size, access and the package you choose. For a price, ring 07833 053749 or send us an email.
Will you walk on the roof?
Only when it is safe. Safe viewpoints, the roof space and a drone where applicable cover most of what’s needed.
Is this an asbestos survey?
No. Asbestos surveys and testing are not part of what we do. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings.
What happens after the survey?
We email you the written report with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Which days do you carry out surveys?
Surveys run on weekdays and at weekends. To find a day that suits you, ring 07833 053749 or use the contact form.
Mitcham 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. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. The covering and its details give the first clues when tracing where water is coming from. Southside House, about 3.6 miles west, is one of the historic houses in the wider area around Mitcham. Older roofs in the wider area can hide decades of patch repairs, so the detail matters.
Trees in and around Cranmer Green shed leaves that can end up in nearby gutters. If you look after a shop, office or commercial unit, for instance near Centrale Croydon, a leak can close part of a shop or office, so finding the cause quickly matters. If you look after a building like St Thomas of Canterbury Catholic Primary School, on a building that size, finding the source of a drip means looking well beyond the stain.
Mitcham is about 2 miles west of Thornton Heath, in Greater London. Surveys in Mitcham work the same way as everywhere we cover: a careful inspection, photos and a written report. Mitcham is one of the towns and villages in Greater London where we work. Our London page covers surveys nearby.

Roof by roof
Valleys
A valley leak can appear well away from the valley inside. We trace the route from the loft where there’s safe access.
Slate and tile slopes
Slipped, cracked or missing slates and tiles let rain onto the underlay. Older felt may hold for a while, but it tears with age.
How the survey works
It helps to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. The visit usually takes an hour or two, more where the leak is intermittent or the roof is large. Many London properties are flats or terraces with no side access, so the back of the roof is often 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 tell us where the water shows and when it appears.
- The visit starts indoors, at the stain and in the loft.
- Outside, we look at every likely route in.
- 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 we arrive
- Make sure the loft hatch can be reached
- If you’re buying, let the agent know when we’re coming
- Check we can get to the back of the property

Related advice
For landlords and managing agents
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work.
Where a roof is shared: access has to be agreed with whoever owns or manages the building. Let us know about it when you book and we’ll plan the survey around it.
What you can safely check yourself
It is useful to keep a record: dates of leaks, photos from ground level and any work done on the roof. Share it with us when you book, as it helps us focus the survey.
During heavy rain, look at the gutters from ground level or a window. Overflowing water can point to a blockage or a sagging run.
