What is Synthetic Slate?

Synthetic slate shingles are made from recycled materials and are designed to mimic the look of authentic slate. While they’re nowhere near the cost of a genuine, natural slate roof synthetic slate roofs are still a luxury roofing product and come with a high price tag because of the processes used to give them the look of authentic slate. Professionals in the industry can likely identify the difference between a natural slate roof and a synthetic slate roof, but your family, friends, and neighbors will just see a beautiful slate roof on your home. 

Synthetic Slate vs Natural Slate

Aside from the price, several key factors differentiate between synthetic slate and natural slate. 


One thing to know about natural slate: it’s HEAVY. In fact, if your home wasn’t built to the specifications necessary to accommodate the weight of natural slight you’ll likely need to have the building retrofitted to safely hold the roof. Fortunately, synthetic slate is an option! Synthetic slate shingles are an extremely lightweight roofing material – even lighter than luxury asphalt shingles! That means weight isn’t something you’ll need to worry about if you choose synthetic slate.

Natural slate roofs can last a literal lifetime or more. A properly installed and flashed slate roof will easily live more than 75 years with 100 years still being completely within the realm of possibility. Synthetic slate roofs can’t boast that long of a life, but you can still expect a synthetic slate roof to last between 40-50 years which still makes it one of the last roofs you’ll ever need to install. 


Because slate tiles are a natural material you can’t count on a manufacturer’s warranty on the materials. While many roofing contractors  will offer a workmanship warranty to cover the installation, this won’t do much good if any of your tiles are bad. Synthetic slate tiles often come with manufacturer warranties which will protect you if there’s a defect in any of the materials.
