Here is what you should know about slate roofs and why people find them appealing.


Slate roofs are beautiful, which is why many homebuyers are drawn to them. This roofing material has been held in high regard by many architects worldwide for centuries due to its clean, classic lines. Slate roofs offer a wide variety of customization as well. It is available in many colors, widths, and thicknesses.


The most important part of slate roos is their durability. Unlike other roofing materials, slate isn’t as susceptible to weather events, remaining almost unaffected by high winds, temperatures, or even hail.

On the other hand, slate roofs can last 40+ years, with some of them exceeding even 75 years. Apart from this, you get lengthy warranties, making slate roofs a long-term investment.

Low Maintenance

Due to their longevity and durability, slate roofs are also relatively low maintenance. This is because slate isn’t susceptible to damage like other roofing materials, such as traditional shingles.

Thus, you won’t worry about regular repairs or replacement issues. Since slate is very dense, it absorbs little water, so it is highly resistant to mold and mildew. A slate roof is a premium material that can raise your home’s value due to its beauty, durability, and low maintenance. However, there are also some cons to consider as well.

Cost & Weight

Probably the biggest con of a slate roof is its pricing. On average, a square foot of slate is about $20. The price is attributed to the installation process and materials. Slate is of premium quality, and since it also costs more to manufacture, the purchasing price reflects this.

Installing a slate roof is also a complex procedure that only expert roofers can handle. The high price of slate roofs drives homeowners to opt for other variants, especially if it isn’t their “forever” home.

Slate roofs are also very heavy, about four times heavier than asphalt roofs. You can expect a weight of about 250 pounds on a square of asphalt shingles. However, a square of slate can weigh between 800 to 1,000 pounds.

The thickness of the slate plays a considerable role, and due to its weight, the load of what the roof frame can handle must be carefully analyzed. Typically, slate roofs are intended for people who expect to stay in their current home for more than 20 years. On the bright side, these people are willing to pay more, making slate an excellent investment to increase their home’s value.
