As a result of its beauty and prolonged longevity, slate roofs have grown widely attractive, especially in the custom real estate market. Slate, a highly resistant metamorphic rock, has become one of the most common roofing materials currently available.

Important Things to Know About Slate Roofing:

In today's real estate market, slate roofing is among the most valuable qualities a house could have. Because of the minerals present within it, slate occurs in a range of colours. It can raise the home's value as it is composed of a quality material that is resilient, long-lasting, and appealing.

Let's Have a Look At the Advantages and Disadvantages of Slate Roofing:


  • Durable: Slate roofs are incredibly long-lasting due to their natural stone composition. Compared to other roofing materials, slates are resistant to extreme weather events such as high winds, high temperatures, and even hail. Slate is also fire resistant since it is made of stone, which helps to avoid fires caused by stray sparks in the air.
  • Longevity: Slate roofs typically endure 75-100 years, although they can endure up to 150 years in some cases. Hard slate has a lifespan of 75 to 200 years, whereas soft slate has a lifespan of 50 to 125 years.
  • Aesthetic Appeal: Slate roofs are popular among homeowners because of their aesthetic appeal. Slate is a beautiful roofing material that architects for ages have prized because of its classic, clean lines. Slate also has a lot more variety than most people think. Slate comes in a range of hues, thicknesses, and textures. It doesn't need any paint or other things to stand out because it's made entirely of natural stone.
  • Easy maintenance: Slate roofs are also very minimal maintenance due to their exceptional durability and endurance. One won't have to worry about repairing or replacing loose or broken tiles because slate is often resistant to the destructive impacts that cause regular tiles to deteriorate. Slate is also highly thick, absorbing relatively little water, making it resistant to mould spores. 


  • Fragility: When stepped on, the slate may easily break. One can have a hard time finding new tiles if the slate breaks since they won't find a match.  If anyone needs to go onto your roof, be sure they're qualified to avoid damaging the tiles.
  • Installation Is Difficult: Installing slate tiles is a difficult task. One should pick a contractor that is experienced in the field. Before people employ a contractor, discover everything possible. Slate roof installation is a complicated operation that usually requires the need for professional roofers.
  • Cost: The expenditure of a slate roof is its most significant disadvantage. One should anticipate paying up to $30 per square foot on average for slate installation. Two things contribute to the more significant cost: the ingredients and the installation. A slate roof has far more expensive materials than a standard asphalt shingle roof. Slate is more costly to produce and, as a result, more costly to buy.
  • Heavy Weight: Slate roofs are quite heavy since they are formed of stone, weighing three to five times as much as an asphalt roof. Slate may weigh up to 1,500 pounds per 100 square feet. Depending on the sort of house people have, it may or may not support the weight. 


A slate roof is one of the most valued characteristics of a house. Slate roofing has different merits and demerits that need to be considered before doing so. Lastly, it can be the longest-lasting roofing material on the market, despite its high total cost and other peculiarities. If you are looking for affordable and durable slate roofing for your home.
