About our roof leak investigation in Croydon
Roof leaks rarely show up where you’d expect. It can run along a rafter, a batten or the underlay before it drips, so a ceiling stain is rarely directly below the cause. We follow it back towards where it starts. A repair aimed only at the stain can miss the cause entirely. Tracing the route first means any work can be aimed at the right place. Common reasons to book are stains around a skylight and damp ceilings under a flat roof, across the roof space, chimney stacks and slate and tile slopes.
Many London homes are well over a century old and their roofs have been patched more than once. Insurers typically exclude wear and tear, so it helps to know whether damage is old or new. A careful look in Croydon tells the two apart where the evidence allows. A written record with photographs helps you explain what was found to whoever deals with it next.
Nothing in the report is left vague: where something needs attention, it says so plainly, and where it can wait, that’s said too.

Before and after the survey
Most of what helps is simple and safe from ground level. A few suggestions:
- Mention any plumbing above the damp area
- Move stored items away from the hatch
- Put a bucket under the drip and move valuables
- Keep a photo record of the damp patch
If condensation is the cause, we explain it, and suggest how the roof space could be better ventilated. It saves chasing a leak that isn’t there.
Have leaves and moss cleared from gutters, valleys and outlets, ideally once the leaves have fallen. Blocked outlets on parapet and flat roofs cause many leaks. Leave the clearing to someone with the right equipment.
Do you need a roof leak investigation in Croydon?
Blocked gutters can look like a roof leak. Hidden gutters behind parapets cause the most trouble, since a blocked outlet sends water over the lining and into the building.
We are often asked to look at:
- Water marks that spread in wet weather
- Wet patches high on an inside wall
- Drips from nail tips in a cold loft
- Damp patches next to the stack
For an older house near a landmark such as St Andrew's, leaks on older roofs frequently start at lead flashings, valleys or around old chimney stacks.
Questions to ask before you book
- Their track record with similar roofs
- Whether you can ask questions once you have the report
- What they won’t be able to tell you
- Whether VAT is added on top
How the survey works
A survey visit follows a simple order: we listen to what’s been worrying you, inspect the roof from every safe vantage point, photograph what we find and record our findings for the written report. Most visits take 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 a visit in 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.
- You let us know where the water appears, when, and what the weather was doing.
- 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 vantage point.
- We email a written report showing where the water most likely gets in.
How to prepare
- Have any paperwork from past roof work to hand
- Keep pets inside or away from the areas we’re looking at
- If you’re buying, let the agent know when we’re coming

Related advice
Why it is worth a survey now in Croydon
A small drip today can be a bigger leak after the next storm. Each storm can open a gap a little more. An investigation now gives you time to plan the work. In a London terrace or conversion, a roof defect rarely stays your problem alone: failed flashings and blocked valley gutters can send water into more than one home. Finding it early keeps the work smaller.
Prices start from £150, inc. VAT, for a Basic Survey. The Standard Survey starts from £250 and the Premium Survey from £400. You will know the price for your roof before booking.

Your questions about roof leak investigations in Croydon
Does a conservation area affect roof work in Croydon?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Can parking be tricky for a visit in Croydon?
It rarely stops a survey, but it’s worth planning. Let us know the parking rules on your street and we’ll work around them.
Will you fix the leak as part of this?
The investigation is about finding the cause. The repair is not part of it. You get a report with photos showing where the water is getting in and what needs attention, which whoever carries out the work can follow.
Is thermal imaging part of a leak investigation?
Thermal imaging is used where it’s useful, and it is part of the Premium Survey. It picks up temperature patterns rather than water, so anything it suggests is checked with moisture readings.
Will you check the loft?
If the survey needs it and the loft space can be reached safely, yes. A clear path to the hatch helps, and if the loft can’t be reached safely, the report says so.
How should I prepare for the leak investigation?
Clear the loft hatch so we can get into the loft space. Gather any photos and notes about when it leaks, and let us know about past repairs. Keep catching drips and keep water away from electrics.
How much does a roof leak investigation cost in Croydon?
Prices start from £150, including VAT. What you pay for your roof depends on its size, height, access and the package, confirmed before anything is booked.
Wind, rain and roofs in Croydon
Historic houses such as Addington Palace, about 2.5 miles east, show how far back building in the area around Croydon goes. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. The covering and its details give the first clues when tracing where water is coming from.
If you look after a shop, office or commercial unit, for example near St George's Walk, a quick answer on where water is coming in keeps a business running. Anyone responsible for a site like Heathfield Academy will know that a leak through a large roof is often found some distance from where the water shows inside.

What you can safely check yourself
You can learn a lot from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please do not climb up for a closer look.
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
