Signs Your Roof Needs Repair Before Winter Hits

As the temperatures drop and the days grow shorter, homeowners across Bath and Somerset start preparing their properties for winter. While tasks like servicing the boiler or clearing the gutters often make the checklist, one area that's frequently overlooked is the roof — your home's first line of defence against the elements.

At KN Roofing & Building, we’ve helped dozens of local homeowners get their properties winter-ready. In this post, we’ll walk you through the key signs that your roof may need repairs before winter sets in — and why acting early can save you stress, money, and major damage down the line.

1. Missing or Damaged Tiles

Take a look at your roof from the ground (or better yet, ask a professional for a roof inspection). If you spot any cracked, curled, or missing tiles, it's a clear warning sign. Even a single missing tile can lead to water getting in and causing damage to the underlay, wooden structure, or even internal ceilings.

Why it matters in winter: Water ingress can freeze and expand in colder temperatures, worsening existing damage and leading to leaks.

2. Moss, Algae, or Debris Build-Up

Moss or algae might seem harmless, but they retain moisture — which is bad news for your roof. In freezing conditions, that moisture can expand, dislodge tiles, and wear down the protective layers beneath.

Similarly, debris build-up (especially in valleys or around chimneys) can block natural drainage and trap water. Over time, this leads to deterioration of both roofing materials and roofline components like fascias and soffits.

3. Leaks or Water Stains Indoors

If you’ve noticed water stains on your ceilings or damp patches in your loft, don’t ignore them. These signs often point to hidden roof damage — such as a broken flashing around chimneys or skylights, or issues with the felt underlay.

In winter, leaks can turn into major structural issues, especially if ice forms in wall cavities or attic spaces.

4. Sagging Roofline or Uneven Roof Ridge

A sagging or uneven roofline is a sign of deeper structural concerns. It could be due to weakened timber supports, excess moisture, or historic damage that's been left untreated.

This is especially urgent before winter — snow (even light snowfall) can add extra weight to an already compromised roof, increasing the risk of collapse or further warping.

5. Clogged or Damaged Guttering

Your gutters play a crucial role in directing rainwater away from your home. But if they’re clogged, cracked, or pulling away from the roofline, they can’t do their job effectively.

Overflowing water can spill onto walls, cause dampness, or pool at the base of your property — leading to issues with your foundation or internal walls.

6. Chimney Wear or Brickwork Cracks

If your roof has a chimney, keep an eye out for signs of wear: crumbling mortar, cracked bricks, or a leaning structure. Chimney damage often affects the flashing — the metal seal that stops water getting in where the chimney meets the roof.

Repairing this before winter helps avoid serious leaks, as heavy rain and frost accelerate deterioration.

7. Roof Is 20+ Years Old

Even if you can't spot visible damage, roofs have a natural lifespan. If your roof is over 20 years old and hasn't had a professional inspection in a while, it’s time to call in an expert. Replacing worn materials early can prevent emergency call-outs during the winter months.

🔧 Why You Shouldn’t Delay Repairs

Winter weather — with its heavy rain, frost, high winds, and even occasional snowfall — puts extra pressure on your roof. Small issues that might seem minor now can become costly emergencies when left unchecked.
