Why it is worth a survey now in Colliers Wood
Water and electrics don’t mix. Keep away from any fitting that water is reaching and have an electrician check it. Then the source needs tracing. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. By the time a ceiling stains, the timbers underneath may have been wet for a while.

About our roof leak investigation in Colliers Wood
The aim is to find where the water is getting in and explain it. The report shows, with photos, where we believe the water gets in and how it travels, plus recommendations on what needs attention. Whoever does the work then has a clear starting point. The investigation finds and explains the cause, while the repair is a separate matter. We survey flat roof details, rooflights and dormers and slate and tile slopes, and people most often book us about leaks below a flat extension roof and leaks that appear only in driving rain.
In converted houses and blocks across London, water from a roof can run a long way before it shows on a ceiling, 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. We check what we’re given access to in Colliers Wood, inside and out. Let us know when the water shows, and in what kind of weather.
If any part of the leaking roof couldn’t be seen safely, we say so in the report. You will know exactly what was inspected and what wasn’t.

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.
What happens on the day
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes about one to two hours for a house, and about three to four hours for a commercial roof. If you have questions on the day, just ask. 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 when you book.
- We help you choose the package that suits the leak.
- We agree a date, including weekends.
- We inspect inside and out, starting from the stain.
- Moisture detection and thermal imaging are used where your package includes them and they help.
- You get photos, the likely cause and clear recommendations.
Getting ready for the survey
- Jot down any questions you want answered
- Leave side gates unlocked

Advice
Do you need a roof leak investigation in Colliers Wood?
Flashings are one of the commonest sources of roof leaks. Where a roof meets a chimney, a wall or a dormer, lead or mortar seals the joint. When lead lifts or splits, or a mortar fillet cracks, rain runs straight in.
Things that often lead to a survey include:
- Drips in the loft during heavy rain
- Leaks at a dormer or roof window
- Staining around the chimney inside
- Water marks that spread in wet weather
If you run a business near Southside Wandsworth, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.
Before you book anyone
- Will they check the loft as well as the outside?
- How much experience they have with roofs like yours
- What exactly goes into their report
- How they’ll see the roof: from ground level, the loft, the roof or by drone
Wind, rain and roofs in Colliers Wood
Many homes in inner London are Victorian and Edwardian terraces, often with Welsh slate roofs. Behind many of their parapets sit butterfly roofs and valley gutters that cannot be seen from the pavement. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. Knowing the roof type helps narrow down where water may be getting in. Historic houses like Southside House, about 2.8 miles west, show how far back building in the area around Colliers Wood goes. 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.
Homes near green spaces such as Figge's Marsh can get more leaves in their gutters in autumn, so outlets and downpipes are worth watching. Landlords with a home close to Tooting station may find that finding the cause of a leak fast keeps a tenant’s home dry and the work focused.

Questions from Colliers Wood
Is my home in Colliers Wood listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Can parking be tricky for a visit in Colliers Wood?
Usually it is manageable with a little notice. Let us know the parking rules on your street and we’ll work around them.
Is it a structural engineer’s report?
No. We are roof surveyors, not structural engineers. We’ll recommend an engineer if we see signs that call for one.
Does the investigation include the repair?
The investigation is about finding the cause. The repair isn’t part of it. You get a report with photos showing where the water is getting in and what needs attention.
Which days do you carry out surveys?
We carry out surveys seven days a week. To find a day that suits you, call 07833 053749 or drop us an email.
