The walls of your home will stay in place, and the roof will not collapse if it can’t support the weight of the slate now. If your home can’t hold the weight of the slate now, you have to retrofit it.
If you have to do retrofitting or new framing before your slate roof can be installed, it will significantly increase the price. If you have to do this before the roof can be installed, you will have to be approved by the structural engineer.

Remember, slate roofs are one of the most durable and longest-lasting roofing materials on the market. But it’s also one of the most expensive types of roofing materials.

You can actually expect to pay at least 4 times more for a slate roof than you would for an asphalt roof. If you’re looking for affordability, a slate roof is probably not the right type for you.

But if you’re looking for a beautiful roof that’ll last and you can handle the cost, it’s going to be the last roof you ever install.
