Slate makes a good roofing material because it lasts much longer than other roof types and looks beautiful. Slate is one of the strongest natural rocks you can put on a house. It does not break easily or rot. Many homeowners pick slate because they want a roof that will last their whole lifetime. According to the roof lifespan data, slate tiles can last 60 to 150 years, which is way longer than most other roofing materials.
How Long Does Slate Last?
Slate roofs are built to last. According to industry data, slate tiles can last between 60 and 150 years. That means your slate roof may still be good long after you sell your house. Other common roofing materials do not last this long.
Think about asphalt shingles. According to RubyHome, asphalt architectural shingles last about 30 years. Metal roofing lasts 40 to 80 years. But slate beats them all. Your slate roof could work for over a century.

What Makes Slate So Strong?
Slate is a natural stone that comes from the earth. It is very hard and does not break down in rain, snow, or sun. Slate does not rot like wood. It does not rust like metal. It does not crack like some other materials.
Water cannot get inside slate. Ice does not crack it. Wind does not bend it. The rock is just too tough. That is why slate roofs stay in great shape for so long.
Slate Vs. Other Roof Types
Here is how slate compares to common roofing materials:
| Roof Type | Lifespan | Cost per Square Foot |
|---|---|---|
| Asphalt Shingles | 20-30 years | $4.25-$8.25 |
| Metal Roofing | 40-80 years | $5.50-$17.05 |
| Slate Tiles | 60-150 years | $12.00-$22.00 |
| Concrete Tiles | 100+ years | $11.00-$19.80 |
Does Slate Cost More Money?
Yes, slate costs more upfront. According to RubyHome, slate costs $12.00 to $22.00 per square foot. That is more than asphalt shingles, which cost $4.25 to $4.95 per square foot. But you get what you pay for.
Because slate lasts so long, you will not need to replace your roof for decades. You may never need a new roof in your lifetime. That means you save money in the long run. Other roofs need to be replaced three or four times before a slate roof needs replacing even once. Many homeowners find that the long lifespan makes slate worth the extra cost today.
