Clapham Park Roof Leak Investigation
Independent roof leak investigations in Clapham Park. We’ve completed more than 5,000 surveys across London and South East England.
- Water through the ceiling under a flat roof
- Water marks that spread in wet weather
- Wet patches on loft insulation
Why act early in Clapham Park
Lingering damp encourages mould on ceilings and walls. Once mould takes hold, it’s harder to clear. Stopping the water is the first step. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. When the stain finally shows, the damage underneath is frequently older than it looks.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Prices start from £150, including VAT.

Roof leak investigations for homes and businesses in Clapham Park
Roof leaks rarely show up where you’d expect. Water frequently travels along timbers or underlay before it finds a way down, so the stain on your ceiling is seldom right under the hole. 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 is needed. Common reasons to book are wet patches high on an inside wall and brown rings on upstairs ceilings, across slate and tile slopes, the roof space and rooflights and dormers.
In a London flat, water can travel some way before it shows. Tracing it back matters, both for dealing with the cause and for any insurance claim. We look at what we’re given access to in Clapham Park, inside and out. It helps to know when the water appears and in what weather.
It is not only a list of defects. It explains what we found, why it matters and what we recommend, so you can decide what to do next.

Questions from Clapham Park
Do you cover Clapham Park?
Yes, Clapham Park is within the area we cover. We cover the whole of London and South East England. You can call 07833 053749 or drop us an email with the address and a few details.
Is my home in Clapham Park listed or in a conservation area?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
Could my leak actually be condensation?
Many apparent leaks turn out to be condensation. Leaks tend to follow wet weather and show in one place, while condensation is often widespread and worst on cold days. We tell you which it is most likely to be.
Is the repair included in the leak investigation?
Our job here is to trace the leak and explain it, not to carry out the repair. The report gives any roofer a clear brief.
Can a leak be traced on a dry day?
Frequently, yes. Leaks leave clues, like staining, damp timber and moisture in materials. Some leaks only show in particular weather, so photos and notes from when it leaks help a lot.
Do I need to be at home?
Not necessarily. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
Will you photograph what you find?
Yes. The report includes photographs of what we found.
DIY checks: what’s safe
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way. That’s where a survey comes in.
It is useful to keep a record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry.
Rented homes, blocks and businesses
Businesses and commercial landlords can book us too, including offices, shops and units. Bigger roofs take more time.
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work.
How the survey works
The visit usually starts outside and finishes in the loft: outside views come first, then the loft space if there’s safe access. In total, it takes about one to two hours at a typical home, and longer for a large or complex roof. In Clapham Park, visits are available on weekdays and at weekends. London parking is often by permit or pay-and-display, so it is useful to know what’s near you, and to clear a path to the loft hatch. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- You get in touch with details of the leak and any photos.
- Inside, we check the damp area and the roof space above it.
- We check the likely entry points outside, like flashings, valleys, chimneys and gutters.
- We use moisture detection, and thermal imaging where it is useful.
- Your report sets out where the water is most likely getting in, with photos and recommendations.
Before we arrive
- Gather any invoices or paperwork from past roof work
- Keep pets out of the way during the survey
- Have any questions written down, so nothing gets missed
Booking a survey
Most bookings start with a short call: ring 07833 053749 or use the contact form and we’ll ask a few questions about the roof. The price is agreed before a date is set.

What we’re asked to look at in Clapham Park
Slipped or missing slates and tiles let rain reach the underlay. Old bitumen felt may cope for a while, but it tears and sags with age, and very old roofs may have no underlay at all. On slate roofs, slipping is frequently caused by corroded nails.
Most people get in touch after spotting something like this:
- Damp on a chimney breast
- Staining where a gutter or parapet meets the wall
- Leaks that appear only in driving rain
- Water through the ceiling under a flat roof
Trees in and around Max Roach Park shed leaves that can end up in nearby gutters, so outlets and downpipes are worth watching.
Questions to ask before you book
- Will the report include photos?
- Whether the inside of the roof is included
- Whether VAT is added on top
- Are they insured for the work?
Wind, rain and roofs in Clapham Park
About 2.6 miles north-west lies Carlyle's House, a reminder of how long the area around Clapham Park has been built on. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area. Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. Behind many of their parapets sit butterfly roofs and valley gutters that can’t be seen from the pavement. If your home in Clapham Park is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Where water gets in depends a good deal on what the roof is made of and how it’s detailed.
Shop and office owners around Southside Wandsworth may find that a quick answer on where water is coming in keeps a business running. Anyone responsible for a site like Glenbrook Primary School will know that tracing a leak on a big roof starts with where the water appears and works back.
