Why get it checked now?
Water damage grows the longer it is left. Wet timbers start to decay, plaster softens and insulation stops working. Tracing it now means less to put right later. Any roof job in Wallington means planning around parking, neighbours and access. That’s a good reason to find problems early, while there’s time to plan.
We offer three survey packages: Basic from £150, Standard from £250 and Premium from £400, all including VAT. What your roof costs depends on its size, access and what you want to find out.
Why us?
- Insured for professional indemnity and public liability
- More than 20 years surveying roofs
- An independent look at the roof
- Photographs and a written report every time

How a roof leak investigation works in Wallington
Flat roofs leak in their own ways. Common causes are splits and blisters, tired upstands and outlets that don’t drain. Standing water puts extra pressure on every weak point. We check the roof surface and the ceiling below. Flat roofs over extensions, garages and dormers are frequent sources of leaks. Felt often lasts around 15 to 20 years, so age is part of the picture. If you’ve noticed water that shows only in certain storms and wet patches on loft insulation, a survey will tell you what’s going on.
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. In Wallington, we inspect what we can reach safely and are given access to. Let us know when the water shows, and in what kind of weather.
The report does not just list problems. It explains what we found, why it matters and what we recommend, so you can plan your next steps.

Roof leak investigations in Wallington: local notes
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. Where water gets in depends a good deal on what the roof is made of and how it is detailed. About 3.4 miles west lies Nonsuch Mansion, a reminder of how long the area around Wallington has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
If you look after a building like Holy Trinity CofE Junior School, a leak through a large roof is frequently found some distance from where the water shows inside. Living close to Carshalton Park is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and blocked gutters overflow and soak walls. Shop and office owners around Centrale Croydon may find that finding where water is getting in quickly keeps disruption down.
Wallington is about 2 miles west of Croydon, in Greater London. If you are in Wallington, booking works exactly as it does anywhere else: a call or an email, a price, then a date. Across Greater London, we cover Wallington. We also survey roofs in London.
Roof leak investigations in SM6 and SM5 work the same way as everywhere else we cover. Streets in the area include Wallington Square, London Road and Maldon Road, all of which we cover.

What we do, step by step
Every visit follows the same pattern: we hear what you’ve seen, look at the roof from every safe viewpoint, take photographs as we go and record our findings for the written report. It normally takes about one to two hours, more where the leak is intermittent or the roof is large. From the street, a London terrace typically shows only its front slope or parapet, so in Wallington we work round the house, using the street, the windows, the loft and any safe vantage point behind it. Shared stairs or a basement flat? Let us know who holds the keys.
- We start with your notes and photos of the leak.
- We examine the damp area and the rooms near 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 we arrive
- Make sure pets are kept safely away
- Make sure we can get to the back of the property
- Mention any parking restrictions on your street

Your questions about roof leak investigations in Wallington
Can parking be tricky for a visit in Wallington?
Sometimes, yes. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well.
Do you cover Wallington?
Yes, Wallington is within the area we cover. We cover the whole of London and South East England. You can phone 07833 053749 or email us with the address and a few details.
What insurance do you have?
Our surveys are covered by professional indemnity and public liability insurance. If you need details for a managing agent or a building owner, just ask.
Is this an asbestos survey?
No. Asbestos surveys and sampling aren’t something we do. Where a material might contain it, like old cement sheets on a building from before 2000, the report flags it.
What’s the best way to book?
Just phone 07833 053749 or send us an email. We will ask a few questions, confirm the price and agree a date, weekday or weekend.
How soon will I get the report?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. All of them come by email, ready to forward.
Why is the stain in a different place from the leak?
Water follows the easiest path, not the shortest. On a pitched roof it often runs down a rafter before it shows. Following that route is what our investigation does.
Rented homes, blocks and businesses
If the property is let, the agent or a tenant can let us in, at a time agreed in advance. Surveys run on weekdays and at weekends, which helps when tenants work during the week.
Letting agents frequently book on a landlord’s behalf, and the report can go to both. Access is agreed with the tenant ahead of time.
What we look for on each type of roof
Flat roof upstands and outlets
On a flat roof, a leak can show some distance from the split. Moisture readings and thermal imaging can help narrow it down where conditions suit.
Chimney stacks
Damp on a chimney breast inside often starts at the top of the stack. Unused flues with open pots can let rain straight in.
Prices for roof leak investigations in Wallington
Every roof is different, so prices are confirmed before you book. This is what makes a difference:
- How tall the building is and how easy the roof is to see
- Roof area
- Extensions, dormers and garages with roofs of their own
- Whether you choose the Basic, Standard or Premium Survey
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package you pick makes a difference too. The price is always agreed first.
What to let us know when you get in touch
What helps most when you contact us:
- Anything about access we should know
- The address and postcode of the property
- What kind of property and roof it is
- Where water is showing inside, if it is
Photos help, if you have them. Pictures from the ground or a window are fine, and please do not climb up for a closer look. To get started, call 07833 053749 or use the contact form.
When you need someone else
Before booking, it’s worth knowing what a survey won’t do:
- Defects hidden under coverings or inside walls without opening up
- Structural calculations (that is a structural engineer’s job)
- An intermittent leak that shows no trace on the day
If in doubt, ring 07833 053749 or use the contact form and we’ll recommend the right survey before you book. What our survey covers.
