Slate Roof Tiles Pros

A slate roof is an excellent investment for your home. The slate is durable and long-lasting. It can add value to your home and is perfect for any roof tile characterised by durability, longevity, and aesthetic appeal. The benefits weigh heavily when talking about the pros and cons of slate roofs.


Slate roofs have long been prized for their beauty and durability. Made from metamorphic rock, they can last for generations with proper care. Many slate roofs installed over a hundred years ago are still in excellent condition.

While slate roofs are more expensive than most others, they offer a level of longevity unmatched by any other material. When installed correctly, a slate can easily last for over 100 years. With such impressive longevity, it's no wonder that slate roofs continue to be one of the most popular choices for homeowners looking for a roof that will stand the test of time.


Slate roofs have a long history dating back to the 11th century. Not only are slate roofs durable and low-maintenance, but they also offer a unique aesthetic that can significantly enhance the curb appeal of any home. Slate roofs are available in various colours, textures, and sizes, making it easy to find a style that compliments the rest of your home.

In addition, slate roofs are known for their distinctive appearance, adding a touch of elegance to any home. Whether you are looking for a classic look or something more modern, slate roofs offer various options to suit your taste.

Low Maintenance

Slates are known for their low maintenance requirements. Many slate roof owners never have to perform any maintenance on their roof. This is in contrast to other roofs, which often require regular cleaning, roof repair, and roof replacement of damaged or missing tiles.

If you are considering a new roof for your home, ask your roofing contractor about the low maintenance of slate roofs. You may be surprised at how easy it is to keep your slate roof looking new.

Slate Roof Tiles Cons 

Slate roofs have been used for centuries, and they're popular today because they look great and last a long time. However, there are some cons to slate roof tiles cons before deciding if this type of roof is right for you.


Slate is a natural stone that is cut into thin, flat pieces. It is then used to cover rooftops. Slate roofs are durable and long-lasting, but they are heavy. This weight can put stress on the framework of a building and require additional support to prevent collapse.


Slate is a brittle material that is susceptible to breaking and chipping. This means that they are easily broken and can be damaged by heavy objects. They are also more vulnerable to wind damage than other types of roofs.

If you live in an area with high winds, it is imperative to ensure that your slate roof is in good condition. While slate roofs have many benefits, their brittleness is something to consider. In this regard, metal roofing is better than slate roofing.


Slate roofs are among the most expensive roofing materials, typically costing two to three times as much as a comparable asphalt shingle roof. The high cost is due to the material itself, as slate is a natural stone that must be mined and then cut into thin pieces that can be used for roofing. Slate roofs also require more labour to install, as each slate must be individually placed on the top. Economically, felt roofing is better than slate roofing.

Frequently Asked Questions

How often does a slate roof need to be replaced?

With proper installation and maintenance, a slate roof can last anywhere from 75 to 200 years, depending on the type and quality of the slate used. Some historical buildings with slate roofs have even lasted for centuries.

Is a slate roof more energy efficient compared to other roofing materials?

Yes, slate roofs are known for their natural insulation properties, which can make homes more energy-efficient. Their thickness helps maintain a consistent indoor temperature, reducing the need for artificial heating or cooling.

Can you walk on a slate roof without damaging it?

It is not advisable to walk on a slate roof. Slate tiles are brittle and can crack or break under pressure. If it's essential to walk on the roof, it should be done with extreme caution, preferably by professionals who are trained to do so without causing damage.

Is it possible to repair individual slate tiles without replacing the entire roof?

Yes, individual slate tiles can be replaced if they are damaged, without the need to replace the entire roof. This is one of the advantages of slate roofs; they can be repaired on a tile-by-tile basis.

How does slate compare to other roofing materials in terms of environmental impact?

Slate is a natural material and, when sourced responsibly, can be considered an eco-friendly roofing option. Its long lifespan also means fewer frequent replacements, reducing waste over time. However, mining and transportation can have environmental impacts, but their longevity and durability often offset these concerns.

Do slate roofs require a specific type of underlayment?

Yes, slate roofs often require a heavy-duty underlayment due to the weight and nature of the material. The underlayment acts as a secondary barrier against moisture and enhances the roof's overall longevity.
