Slate roofing is a natural stone roofing material that comes from rock quarries and lasts an extremely long time. According to industry data, slate tiles can last 60 to 150 years, making them one of the most durable roof options available. Slate is heavy, fireproof, and very expensive upfront. However, many homeowners choose slate because it looks beautiful and protects homes for decades. If you want a roof that will outlast most other materials, slate is the best choice.

How Long Does Slate Roofing Last?

Slate roofing is extremely durable. According to roofing data, slate tiles last between 60 and 150 years depending on quality and weather. This makes slate one of the longest-lasting roofing materials in the world.

Most other roofing materials need replacement much sooner. For example, asphalt shingles last only 20 to 30 years. Metal roofing lasts 40 to 80 years. Slate beats them all. Your great-grandchildren might still use your slate roof.

How Much Does Slate Roofing Cost?

Slate roofing is very expensive. According to RubyHome, slate tiles cost between $12.00 and $22.00 per square foot when installed. For a typical 1,700 square foot roof, that means you would pay between $20,400 and $37,400 just for materials and installation.

This is much more than other roofing types. Basic asphalt shingles cost only $4.25 to $4.95 per square foot. Even metal roofing costs $5.50 to $17.05 per square foot. Slate costs more because it is mined from nature and lasts so long.

Why Choose Slate Roofing?

Slate has several big advantages. It does not burn, so it is fireproof. It does not rot or decay. It looks elegant and increases your home’s value. According to the NAR Remodeling Impact Report, roof replacement can return up to 110% of costs when you sell your home, meaning you make money back.

Slate also needs very little maintenance. You do not have to replace shingles every 20 years. One slate roof lasts a lifetime. Many historic buildings still have their original slate roofs from over 100 years ago.

Is Slate Right for Your Home?

Slate roofing is not for everyone. Your home’s structure must be very strong because slate is heavy. Older homes often cannot support a slate roof without expensive reinforcement. A professional roofer must inspect your home first.

You also need money to afford slate. According to industry data, the average roof replacement costs between $5,868 and $13,217, but slate costs much more. If you plan to stay in your home for many years and want the best roof possible, slate is worth the investment.
