However, like all things, it has both benefits and downsides, which homeowners need to consider before making a decision. In the following sections, we’ll delve deeper into the pros and cons of slate roofing, providing you with comprehensive information to help you decide if slate is the right choice for your home.
The History of Slate Roofing
The history of slate roofing is one that spans centuries and continents. It’s rich with tradition, innovation, and endless examples of architectural beauty. The use of slate as a roofing material can be traced back to the 12th century in Wales and the west of England. Today, it is still highly valued for its longevity, durability, and aesthetic appeal.
Slate roofing’s origin can be traced back to the Roman conquest of England during the first century AD. The Romans discovered vast slate deposits in North Wales and quickly began using it for roofing on their fortresses and villas. The tradition was then carried on by the Anglo-Saxons and Normans, who further developed methods for mining and cutting slate.
During the Industrial Revolution in the 18th and 19th centuries, slate roofing saw a significant surge in popularity. Technological advancements made it easier to quarry, cut, and transport slate. As a result, even common houses could now afford to have this durable, fire-resistant material on their roofs. This is when we started asking ‘Why is slate used for roofing?’ more intensively because its benefits became more apparent.
In North America, slate roofing was first introduced by the early European settlers. Initially, they used it mostly for public buildings due to its high cost. However, by the mid-19th century, slate quarries were established in several U.S states including Pennsylvania, Vermont, and Virginia making it more accessible for private homes.
Despite its popularity throughout history, the use of slate for roofing declined in the mid-20th century due to increased competition from cheaper synthetic materials like asphalt shingles. However, in recent years there has been a resurgence of interest in traditional building materials like slate. More homeowners are seeing the value in investing in a roof that can last a lifetime (or two).
So, why is slate used for roofing? The answer lies in its history. Its longevity has been proven over centuries and across continents. It can withstand harsh weather conditions, is fire resistant, and adds a unique, natural beauty to any building.
Today, many historic buildings around the world still boast their original slate roofs – a testament to this material’s durability and timeless appeal. As we look to the future, it’s safe to say that slate roofing will continue to have a place in both traditional and modern architecture.
Characteristics of Slate that Makes It Ideal for Roofing
One might ponder, ‘Why is slate used for roofing?’ This question arises because of the prevalence of slate as a preferred choice for roofing material in many buildings around the world. The answer lies in the unique and impressive characteristics of slate that make it ideal for this purpose.
Slate is a natural stone that is known for its durability and longevity. Unlike other materials, slate roofs can last hundreds of years instead of simply tens. This is an extremely important factor when selecting a roofing material, as you want something that will stand the test of time and weather changes.
Another factor that makes slate an excellent choice for roofing is its resistance to fire. Most roofing materials are combustible to some degree but slate is completely fireproof. In case of a fire, a slate roof can play a significant role in preventing the spread of flames to the upper parts of the building.
Interestingly, slate is also very environmentally friendly. The production of synthetic roofing materials often releases harmful emissions into the atmosphere, while slate extraction has minimal environmental impact. Plus, because slate roofs last so long, they don’t need to be replaced often which reduces waste.
The aesthetic value of slate cannot be overlooked either. Slate tiles have a distinctive and attractive appearance that adds character and value to any building. They come in a variety of colors and textures, providing many options to suit different architectural styles.
Despite being quite heavy, which requires strong supporting structures, this weight is an advantage when it comes to wind resistance. Slate shingles will stay put even under strong gusts making them an excellent choice in areas prone to high winds or storms.
In addition to all these advantages, slate also requires very little maintenance once installed correctly. Its low water absorption properties help prevent frost damage and cracking, thus reducing any need for regular repairs or replacements.
In summary, the reasons why slate is used for roofing are manifold. Its durability, fire resistance, environmental friendliness, aesthetic appeal, wind resistance, and low maintenance needs are all compelling factors. Therefore, while slate may initially be more expensive than other roofing options, its long-lasting quality and other advantages make it a highly cost-effective choice in the long run.

In conclusion, the durability, fire resistance, aesthetic appeal, eco-friendliness, and low maintenance requirements are some of the key benefits that answer the question – ‘why is slate used for roofing?’. Although slate roofing requires a higher upfront investment, the numerous advantages it offers make it a wise choice for any homeowner who values longevity and aesthetic appeal.
Installation Process of Slate Roofs
Many people often ask, “Why is slate used for roofing?” The answer lies in its high durability, aesthetic appeal, and longevity. However, the performance and effectiveness of slate roofing significantly depend on the quality of its installation. The installation process of slate roofs is a meticulous procedure that requires professional expertise and precision.
The first step in the installation process involves the preparation of the roof deck. The deck should be clean, dry, and smooth to ensure the slate tiles lay flat. Installers also need to install a layer of roofing felt over the deck to provide additional protection against moisture.
The next step involves laying out the starter course. This involves placing a row of slates upside down and snapped at the bottom edge of the roof. An addition row of slate is then laid out right side facing up on top of this initial layer. This double layer at the eave edge provides an effective moisture barrier and gives a thicker appearance to this visually important area.
Once this setup is complete, the regular pattern of slate tiles begins. Slates are typically installed with two nails driven through each tile into the roof deck and overlapped in a way that makes them watertight yet allows them to ‘breathe’. It’s important to note that these slates must be laid out in such a way that the joints between them do not align with the joints in the course below.
Once all tiles are installed, flashing, which are pieces of metal installed to prevent seepage of water around any intersection or projection in a roof such as vents, chimneys or adjoining walls can be put in place. Traditionally copper or galvanized metal is used for this purpose.
Finally, after all slates have been installed, they may need to be trimmed or cut to fit the dimensions of the roof. This is done using a slate cutter or a slate ripper, which is designed to cut and trim slates without causing them to break.
The installation process of slate roofs may seem challenging and time-consuming because it is. However, the endurance and aesthetic quality that slate roofing provides is worth the additional effort and cost. In fact, when installed correctly, a slate roof can last over a century, making it an excellent long-term investment for your home.
Maintenance and Durability of Slate Roofing
If the phrase ‘why is slate used for roofing’ has crossed your mind, it could be attributed to the reputation this material has built for itself in terms of maintenance and durability. The longevity of slate roofing is a significant factor that contributes to its popularity among homeowners.
Slate roofing, often referred to as the ‘forever roof’, can last over 100 years if properly maintained. This surpasses the life expectancy of other roof materials like asphalt shingles, which typically last between 20 to 30 years. This outstanding durability can be attributed to the natural properties of slate; it’s basically a rock! Its hardened and dense structure makes it resistant to harsh weather conditions including heavy rain, snow, high winds and even hail.
Furthermore, slate roofs are fireproof. They don’t ignite even when exposed to external fire hazards, providing an extra layer of safety for your house. This characteristic alone answers the question, ‘why is slate used for roofing’, for many homeowners concerned about safety.
In terms of maintenance, slate roofs require minimal effort. Because of their inherent strength and durability, they do not need frequent repairs or replacement parts. However, despite being very durable, they may sometimes crack or break due to pressure or impact from heavy objects such as tree branches. In such instances, only the damaged slates need to be replaced rather than the entire roofing system. It’s advisable to have a professional inspect your slate roof periodically to address any potential issues early.
While slate roofs may come with a heftier initial price tag compared to other roofing materials, their minimal maintenance costs and exceptional lifespan make them a cost-effective solution in the long run. When you consider that a slate roof could potentially outlast your time in the house, it takes on additional value as a ‘one-time investment’.
Overall, the combination of durability, fire resistance, low maintenance, and remarkable lifespan make slate roofing a worthy consideration for homeowners. So, next time someone asks ‘why is slate used for roofing’, you can point them to its impressive durability and easy upkeep.

Slate is among the most expensive roofing materials in the market. The initial cost includes both the purchase of high-quality slate tiles and the professional installation, which often requires a specialized skill set. It’s worth noting that these costs can vary widely depending on a range of factors, including the type and quality of slate used, roof complexity, and geographic location.
However, when considering longevity and durability, slate roofing provides exceptional value for money. Natural slate roofs have an incredibly long lifespan, often exceeding 100 years.

Environmental Impact of Slate Roofing
Understanding the environmental impact of slate roofing helps us answer the question, ‘Why is slate used for roofing?’. Slate, being a natural material, has significant environmental benefits that make it an ideal choice for roofing. It’s not just about its aesthetics, longevity, and durability but also about its low ecological footprint.
Slate is a naturally occurring stone that is merely cut into thin tiles for roofs – no additional materials or processes are required. This absence of chemical processes means that the production of slate tiles produces little to no pollution.

As a result, fewer raw materials are consumed over time.
In addition to its long lifespan, slate is a completely recyclable material. Old or broken slates can be ground down and reused in various ways instead of ending up in a landfill like many other roofing materials. Therefore, choosing slate as a roofing material can significantly decrease waste.
Furthermore, because slate is a natural material, it does not release any harmful chemicals or substances into your home or the environment during its lifespan. This makes it an ideal choice for those looking for ‘green’ building materials.
In conclusion, when asking ‘Why is slate used for roofing?’, one of the primary reasons is its minimal environmental impact. Between its low resource consumption, long lifespan, and recyclability, slate is an excellent choice for anyone looking to make a sustainable roofing choice.
