What is the longest-lasting roofing material?
While there are plenty of durable roofing options, the longest-lasting roofing material is slate.A slate roof is a premium roof system made primarily out of natural slate tiles and other slate roofing materials.
It’s hard to put an exact number on the lifespan, but there’s no reason a slate roof shouldn’t last around 75 years or even over 100. As long as your slate roof is properly installed and flashed properly, it’ll be the last roof you ever put on your home.
This means even your grandkids won’t have to worry about it. On top of being the longest-lasting roofing material, it also has one of the highest curb appeals.
4 things to know about getting a slate roof
Homeowners like slate roofs because of the fact it's the longest-lasting roofing material. But the truth is, a slate roof won’t be an option for everyone.
Before deciding if a slate roof is right for you, learn the 4 things every homeowner needs to know about this premium roof system.
1. A slate roof is one of the most expensive roofing materials
Like I just said, a slate roof is a premium roof system. Because it’s a premium roof, you’ll have to pay a premium price.
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. This makes a slate roof one of the most expensive roofing materials on the market.
For comparison, you can actually expect to pay at least 4 times more for a slate roof than you would for the most commonly used asphalt roof. This won’t be an option for most homeowners, but a slate roof is well worth the money if you can afford the investment.
2. The weight factor of a slate roof
Slate roofs are incredibly heavy due to the weight of the slate itself. Because of this, your home has to be able to hold the weight of a slate roof.
If your home can’t handle the weight of slate the way it is, you’ll have to retrofit it. Retrofitting must be approved by a structural engineer and must be done before the roof can even be installed.
Be aware, it’s really going to add to the cost of your new slate roof if you have to do retrofitting or new framing. If you’re seriously considering a slate roof, ask your roofing contractor about the weight factor and how retrofitting your home impacts the final price of a slate roof.
3. You must hire a roofing contractor that has experience installing slate roofs
Speaking of your local roofing contractor, hiring one that has experience installing and working on slate roofs is crucial. Each individual slate tile has to be carefully handled because they’re easily breakable.
The installers also need to know how to walk on a slate roof without breaking the tiles. Because of this, it takes real skill and proper training to handle and install a slate roof.
If the installers don’t have experience working with slate, the slate tiles will break, you’ll have problems (leaks), and your long-lasting roof’s life will be cut short. No matter if you need repairs or a full roof replacement, your contractor plays a huge role in the life you get out of your slate roof.
4. You’ll have no material warranty for your slate roof
But the material warranty for a slate roof is a little different from other roofing materials. Because slate tiles are naturally made, there’s actually no manufacturer material warranty on the roofing materials themselves.
Without a material warranty, you only have your contractor’s workmanship warranty to rely on if there's ever a problem with your slate roof. For this reason, it’s crucial to hire a high-quality local roofing contractor that stands behind their work.
Just keep in mind that a roofing contractor’s workmanship warranty can be anywhere from a tail light warranty (as soon as you see their company truck’s tail lights disappear, your warranty is gone), to a two-year, five-year, 10-year, or even a lifetime warranty.
But to get the best protection possible for your slate roof, you should always look for a contractor that offers you a lifetime warranty or close to it (25 years).
