Here is some information on the slate variations that you can install on your rooftop:

Natural Slate

When people talk about slate roofs, natural quarried slate is what comes to most people’s minds. Natural slate has an exceptionally long lifespan, lasting over a century with proper care and maintenance. It handles thermal expansion and contraction well and is impervious to damage caused by ultraviolet rays. Due to the lack of manufacturing processes, natural slate is one of the most eco-friendly roofing options available, and discarded slate can be repurposed in many ways. A reputable San Jose roofing contractor typically offers slate in a wide variety of colors. Depending on the source, you’ll find natural slate in shades of gray, blue, and even red.

Cement Slate

Cement slate is quickly becoming a popular alternative to natural slate, largely thanks to its more attractive upfront cost. As opposed to more natural slates, cement slate can come in an even wider variety of factory-applied colors and custom formats such as diamond-shaped slate. It has the added benefit of being much lighter than natural slate and can be installed on existing roof decks without additional reinforcement. It must be noted that cement siding has a lower expected lifespan when compared to natural slate but is still far longer than other options such as asphalt shingles.

The Pros and Cons of A New Slate Roof

We understand that the roof you choose for your home or business is an important decision. Below you’ll find some points to consider to inform your choice better.

Pros Of Slate Roofing

  • Longevity: The average slate roofing system has a life expectancy between 50 and 75 years on the low end, depending on if you use soft or hard slate, and can last between 125 and 200 years on the high end. This is why slate is considered a “lifetime” roof for a building, as slate roofing can significantly enhance curb appeal and resale value.
  • Low-maintenance: Synthetic slate is lightweight, yet strong, and requires little maintenance or upkeep.
  • Sustainability: Slate is a green roofing material due to its durability and fairly low impact on manufacturing. It can be reused and recycled at the end of its service life.

Cons Of Slate Roofing

Extra Care Required During Installation: If a slate roof isn’t correctly installed and reinforced, you will quickly experience moisture issues with the roof. Slate roofs should only be installed by contractors that specialize in slate, so you must do your due diligence before hiring an installer.

Repair Difficulties: Slate can break when walked on, so it is more difficult to navigate through roof and chimney repairs without a professional.
