Storms are a regular part of the British winter – and while most homes are built to withstand the elements, even the toughest roofs can suffer damage when the wind, rain, and hail strike in full force.

Storm damage isn’t always obvious, and in many cases, it goes unnoticed until water starts seeping through ceilings or walls. The sooner you can identify potential issues, the better chance you have of avoiding major repair costs.

At CPM Trades, we specialise in roof inspections and emergency repairs across Croydon, Bromley, Beckenham, Shirley, and surrounding areas. In this blog, we’ll walk you through the most common signs of storm-related roof damage – and what to do if you spot them.

1. Look for Missing or Slipped Tiles

One of the most visible signs of storm damage is missing or displaced roof tiles. High winds can lift or shatter tiles, especially if they were already loose or ageing. This is particularly common on older properties or roofs that haven’t had recent maintenance.

From ground level, scan your roof for:

  • Gaps or visible patches

  • Misaligned or upturned tiles

  • Broken shards on the ground near your home

Even a single missing tile can expose the underlay to rain and lead to water ingress. If you spot anything unusual, don’t delay in arranging a professional inspection.

2. Check Gutters for Debris or Overflowing Water

Gutters often take a beating during stormy weather. Heavy rain, leaves, and debris can clog them quickly, and strong winds may even dislodge sections completely. Damaged or overflowing gutters can lead to water running down walls or pooling near your foundations, increasing the risk of damp and structural issues.

After a storm, check for:

  • Overflowing water when it rains

  • Sagging or broken guttering

  • Debris build-up (tiles, leaves, moss)

  • Leaks at the joints or downpipes

Blocked or damaged guttering is something we regularly fix during roof and guttering services in South London, and it’s crucial to get it sorted before it leads to more serious problems.

3. Inspect the Loft or Ceiling for Water Damage

Not all roof damage is visible from the outside. If water has breached your roof covering, the first signs often show inside your loft space or on your ceilings.

Take a torch into your loft and check for:

  • Damp patches on timber or insulation

  • Water stains or dark streaks

  • Mould growth

  • A musty smell indicating trapped moisture

On ceilings, look for bubbling paint, yellow stains, or small patches of discolouration – all of which can indicate a hidden leak.

Prompt detection is key. CPM Trades can locate the source of the leak and carry out cost-effective repairs before the issue escalates.

4. Watch for Flashing Damage Around Chimneys and Roof Valleys

Flashing refers to the metal strips that seal joints and vulnerable areas of your roof – such as around chimneys, skylights, vents, and roof valleys. These are prime areas for water to enter if the flashing becomes cracked, bent, or lifted in a storm.

Common signs of flashing damage include:

  • Water dripping near a chimney or skylight

  • Rusted or missing flashing

  • Loose mortar or exposed joints

It may not be obvious from the ground, but if you suspect an issue, we recommend having a professional roofer take a closer look. We offer roof inspections throughout Bromley and Croydon to help identify flashing issues before they lead to major leaks.

5. Look Out for Sagging or Uneven Rooflines

A more serious consequence of storm damage – particularly after prolonged rain – is sagging or uneven sections of your roof. This can be a sign that water has soaked into the timbers or that structural damage has occurred.

This isn’t something to ignore. A sagging roof could indicate:

  • Rotting or waterlogged joists

  • Broken rafters

  • Compromised underlay or battens

Structural roof issues require urgent attention to prevent further collapse or long-term water damage. If you notice any unevenness, CPM Trades can assess the situation quickly and recommend the best solution.

6. Don’t Ignore Minor Signs – They Add Up

Storm damage isn’t always dramatic. Sometimes, it’s a combination of small issues – a cracked tile here, a loose flashing there – that adds up to major leaks over time.

Even if your roof looks fine from the outside, if you hear rattling in the wind, notice water where it shouldn’t be, or find small debris around your garden or driveway, it’s worth having a professional check things over.

We offer expert roof checks for peace of mind, especially after heavy storms or persistent rain.
