Slate is a good roofing material because it lasts a very long time, resists damage, and looks beautiful on any home. According to industry data, slate roofs can last 60 to 150 years, which is much longer than other materials. This means you buy it once and it stays on your roof for your whole life. Slate also handles bad weather well and keeps your home safe. It costs more upfront, but it pays for itself over time because you rarely need repairs.
How Long Does Slate Last?
Slate roofs are built to last. According to the provided roofing material lifespan data, slate tiles can last 60 to 150 years. That is longer than almost any other roof you can buy.
Compare this to other common materials. According to RubyHome, asphalt shingles last only 20 to 30 years, and metal roofing lasts 40 to 80 years. Slate beats them both by a huge amount. Your grandchildren could still be living under the same slate roof you put on today.

Why Is Slate So Strong?
Slate is a natural stone. It does not break down like other materials do. Wind, rain, hail, and snow do not hurt it easily.
This matters a lot. According to the Insurance Information Institute, hail damage cost U.S. homeowners $160 billion in reconstruction cost value in 2024. Slate does not get damaged by hail like asphalt shingles do. It also does not leak or rot the way wood shakes can.
What Is the Cost of Slate Roofing?
Slate costs more than other roofs at first. According to RubyHome’s material cost data, slate tiles cost between $12.00 and $22.00 per square foot for installation. For a 1,700 square foot roof, that could be $20,400 to $37,400.
But you save money over time. You do not pay for repairs like you would with cheaper roofs. You do not replace it every 20 years. Many homeowners say the extra cost is worth it.
Does Slate Add Value to Your Home?
Yes. Slate looks fancy and upscale. It makes your home stand out in the neighborhood.
When you sell your home, buyers see a quality roof. According to the NAR Remodeling Impact Report 2025, roof replacement can give you a return on investment of up to 110% at home resale. Slate is even better because it shows your home is well cared for and built to last.
