What is a slate roof?

Before we get to how much it will cost, you need to know what a slate roof is. A slate roof is a premium roof system made primarily out of natural slate tiles and other slate roofing materials.

It’s one of the most beautiful and long-lasting roof systems on the market. Because of its aesthetics, shingle manufacturers make asphalt shingles to mimic the look of a slate roof. 

The slate itself is mined (mostly in Italy) and cut into square tiles that are installed on your roof one at a time. Every individual tile has to be handled carefully because they’re easily breakable.

It takes a really skilled roofer or someone that’s been trained properly to handle and install the slate tiles. Because of this, it’s crucial to hire a local roofing contractor that has experience installing slate roofs.

No two roofs are ever going to be the same price. So, the price for your new slate roof wouldn’t be the same as your neighbors. 

Because of this, it’s impossible to give you an exact price without coming to your home and inspecting your roof. However, I can give you an idea on a price range for a new slate roof.

For labor and materials, you can expect a slate roof to start around $15.00 per square foot and has the potential to get up to around $30.00 or more per square foot.

That means you can expect to pay at least 4 times more for a slate roof than you would for an asphalt roof. This makes slate one of the most expensive types of roofing materials on the market for a roof replacement. 

What impacts the cost of your new roof?

Now that you have an idea of the size of your slate roof investment, aren’t you curious about everything that impacts the cost? Be aware, the price for your new slate roof depends on multiple factors that vary from roof to roof. 

To better help you understand where your investment goes when making this purchase, I’ve comprised a list of the factors that directly affect the price of your new slate roof.

  • The type of roof you choose (slate roof)
  • The rest of the roof system’s materials
  • Labor and time
  • Your roof’s accessibility
  • The number of penetrations your roof has
  • Your roof’s size and the complexity of it
  • The amount of decking that may need to be replaced
  • Dump fees
  • Operating costs

This is just a quick rundown of what impacts the cost of your new slate or any type of roof. For a deeper breakdown of these cost factors and what they mean to your roof investment, read this article on the 9 factors that impact the cost of your new roof.

The weight factor of a slate roof

You just learned what impacts the cost of your new roof. But there’s still one more factor specific to a slate roof that wasn’t included in the list above. 

That’s the weight factor that comes with getting a new slate roof. Slate roofs are incredibly heavy. Because of this, your house actually has to be built or framed to carry the weight of the slate tiles. 

This ensures the walls of your home won’t fall out and that your roof won’t cave in. If your home can’t withstand the weight of the slate the way it is, you’ll have to retrofit it so it can hold the weight. 

This has to be approved by a structural engineer, and it must be done before the roof can even be installed. If you have to do retrofitting or new framing, it’s really going to add to the cost of your new slate roof. 

If you’re interested in a slate roof, it’s crucial to ask your roofing contractor about the weight factor and how retrofitting your home to handle the weight impacts the final price of a slate roof.
