Your roof is a critical part of your home. Not only does it have a structural purpose, but it keeps you dry, warm, and sheltered from the elements. However, not all roofing materials offer the same level of protection from the weather. In fact, depending on the material of your roof, different weather events can have a variety of impacts.

Knowing how the weather affects your roofing material can help you better understand how to keep it in top condition and when you might need to consider roof cleaning, repairs, or replacements. So let’s take a look at how common roofing materials hold up in different weather conditions.


Common roof materials

Whether you live in a chocolate box cottage or a modern apartment, knowing how to maintain your roof is key. From broken tiles to moss growth and blocked gutters, every roof material will come up against different issues — and when you know what to look for, you can spot problems before they lead to too much damage.


Made from bundles of dried straw or reeds, thatched roofs offer a traditional, rustic appearance that’s popular in rural areas.


Brick is another classic roofing material due to its durability and stability. Clay and concrete brick tiles are especially common, and you’ll often find brick roofing materials used on historical buildings.


Slate roofing is renowned for its durability and elegant appearance. It comes in various colours and sizes, and is a popular choice for both traditional and contemporary property designs in the UK.


How do different weather conditions affect these roof materials?

As you can see, thatch, brick, and slate roofs all have different properties — and this means weather conditions affect them in different ways.

Wet weather

Thatched roofs are vulnerable to moisture; wet weather can cause thatch to become waterlogged, leading to rot, mould, and decay. It’s important to keep an eye on thatched roofs and carry out regular maintenance, including rethatching.

When it comes to brick roofs, wet weather doesn’t pose a significant threat. This is because bricks aren’t very porous. However, moisture can lead to mortar joints deteriorating over time so older roofs may require repointing.

Slate roofs are highly resistant to moisture. They effectively shed water, preventing leaks, making this roofing material an ideal choice in very wet locations.

Cold temperatures

Cold weather isn’t great for thatched roofs. It can freeze the thatch and heavy snow loads can put pressure on the roof structure. It’s a good idea to remove snow from your thatched roof where possible.

Brick roofs, on the other hand, cope with cold temperatures. You may, however, need to insulate your brick roof to prevent heat loss and ice dam formation, which can damage gutters.

As for slate, this roofing material is excellent in cold climates. Slate’s durability and resistance to freeze-thaw cycles makes it well-suited for icy conditions.

High winds

Strong winds can dislodge or damage thatch so it’s essential to carry out regular roof checks and repairs in windy areas.

In contrast, both brick and slate roofs are both relatively wind-resistant when installed properly and securely fastened by a professional.

Hot weather

During hot weather, UV ways and high temperatures can affect different roofing materials. Thatch can become dry and brittle, so you’ll need to look into regular treatments to protect against UV damage.

Brick roofs perform well in hot weather and can help regulate indoor temperatures. However, slate roofs tend to be the best option for hot climates as they are durable, UV-resistant and don’t degrade under prolonged sun exposure.
