Roof leak investigations for homes and businesses in South Croydon
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, and recommends what should be done. Whoever does the work then has a clear starting point. The investigation finds and explains the cause, and the repair itself is a separate job. We survey chimney stacks, slate and tile slopes and the roof space, and the problems we are asked to look at most are condensation that looks like a leak and leaks at a dormer or roof window.
In London, leaks often start somewhere hidden: the valley gutter in a butterfly roof, a parapet gutter, a chimney flashing or the flat roof over a rear extension. For a leak or storm damage in South Croydon, those hidden details are where the inspection begins. Water from a hidden gutter can run along joists and show up a room or two away.
If any part of the leaking roof couldn’t be seen safely, we say so in the report. That way, it is clear what was covered and what wasn’t, and what we’d suggest next.

Why get it checked now?
Leaks tend to get worse, not better. Wind lifts loose slates further and gaps widen. An investigation now gives you time to plan the work. London’s older roofs frequently have bitumen felt underlay or none at all, so a slipped slate can soon mean water inside. Left unchecked, water soaks into timber and plaster and the damage spreads.
To find out what your survey will cost, phone 07833 053749 or use the contact form and tell us about the roof. We will confirm the figure before booking.

What a roof leak investigation looks like in South Croydon
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. About 2.4 miles east lies Addington Palace, a reminder of how long the area around South Croydon has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
Take a building like Purley Oaks Primary School: water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot. Landlords with a home close to Sanderstead station may find that a tenant living with a leak needs the cause found, not just the stain painted over.
South Croydon is about 1 mile south of Croydon, in Greater London. Bookings from South Croydon are handled just like any other: get in touch, agree the price and pick a day. South Croydon is one of the towns and villages in Greater London where we work. London is in our area too.
All of CR2, CR8 and CR0 is covered for roof leak investigations. Local streets include Edgar Road, Bynes Road and Grange Road, all of which we cover. We also cover the places around South Croydon: Croydon (1 mile north), Coombe (1 mile north-east), Sanderstead (1 mile south-east), Riddlesdown (2 miles south) and Selsdon (2 miles east). Further out, we also cover London (10 miles north), City of Westminster (11 miles north), Marylebone (12 miles north), Kensington (11 miles north-west), St Pancras (12 miles north) and Shoreditch (12 miles north).
What’s near South Croydon
We work in homes and buildings around The Purley Arms, Harris Academy Purley and Duppas Hill. There’s a railway station in South Croydon itself: Sanderstead station. Other landmarks nearby include Purley War Memorial Hospital (1.2 miles south-west) and Croydon Airport Visitor Centre (1 mile west). Not far away are Roundshaw Downs and Duppas Hill.
When to book a survey in South Croydon
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.
Typical things we’re asked to look at include:
- Damp on a chimney breast
- Staining where a gutter or parapet meets the wall
- Drips in the loft during heavy rain
- Water that shows only in certain storms
Shop and office owners around St George's Walk may find that water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.
Choosing a roof surveyor
- Whether the roof space is looked at, where there is one
- What follow-up you get after the report
- Which parts of the roof they’ll actually see
- Whether they hold professional indemnity and public liability insurance
How the survey works
You don’t need to do much on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll get on with the inspection. The survey itself takes an hour or two on an ordinary house, and more on a big or complicated roof. London terraces rarely offer a view of the whole roof from one spot, so a visit in South Croydon moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Let us know who holds the keys.
- We start with your notes and photos of the leak.
- Inside, we look at the stain and the ceiling around it.
- In the loft, we follow any signs of water back towards the roof.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from every safe viewpoint.
- You receive a report with the likely source, photos and recommendations.
Before the survey
- Let us know about parking before the day
- Agree roof access with the managing agent if it’s shared
- Keep pets inside or away from the areas we are looking at
How to book
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. Otherwise, simply ring 07833 053749 or drop us an email whenever suits you.

How we price roof leak investigations
We confirm the exact price before booking. These are the things that affect it:
- Roof area
- The type of building, from a house to a block or an office
- Any need for thermal images or a drone flight
- The height of the building and how the roof can be seen safely
Roof leak investigation starts from £150, including VAT. What you pay depends on how big and how high the roof is, access and the package you choose.
What to tell us when you contact us
A few details help us recommend the right survey and price. When you contact us, tell us:
- Why you want a survey: buying, a leak, a storm or new work
- The property’s address and postcode
- When you need the report by
- Where any leaks, stains or damp patches show inside
You can call us seven days a week, including Saturdays and Sundays. For a price or to book, phone 07833 053749 or email us.
Should I look at the roof myself first?
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.

How the survey changes by roof type
Lead flashings
Water from a failed flashing can travel down the wall or along a rafter. That is why we check the flashings near a stain, not just the one directly above.
Valleys
Stains from a valley leak frequently show some distance off. We trace the route from the loft where there’s safe access.
Your questions about roof leak investigations in South Croydon
Does a conservation area affect roof work in South Croydon?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Is South Croydon in the area you cover?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Why doesn’t the damp patch line up with the hole?
Water rarely drops straight down. It can follow a timber or the underlay a long way first, so the entry point is frequently well away from the mark. We follow the route back instead of guessing.
Can you always find the source?
We can’t promise to find every leak on one visit. Many leave clear signs, but some only appear in certain weather. The report sets out what we found and the most likely routes.
Is this a RICS survey?
No. This is a survey of the roof only, and it isn’t a RICS Level 2 or Level 3 survey. Many buyers have both.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years.
Will you photograph what you find?
Yes. Photos are taken throughout the survey, and the report uses them to show each finding.
