How Much Does A Synthetic Slate Roof Cost?

When it comes to roofing options, synthetic slate has gained popularity as a cost-effective alternative to natural slate. This durable and aesthetically-pleasing roofing material offers the look of real slate without the high price tag. If you’re considering installing a synthetic slate roof, you may be wondering about the cost. In this article, we’ll look at types of synthetic slate roofs and the things that affect how much they cost, including the size of your roof and ease of installation. 

What Is A Synthetic Slate Roof?

A synthetic slate roof captures the timeless allure of natural slate through the ingenious use of synthetic materials such as plastic, rubber, or fiberglass. This innovative roofing solution combines traditional aesthetic charm and resilience of slate with modern engineering. While echoing the elegance of authentic slate, synthetic versions are notably lighter, simplifying installation and potentially reducing structural demands. Moreover, their cost-effectiveness presents an appealing choice for those seeking a sophisticated appearance without the investment required for natural stone. Whether replicating the nuanced textures or replicating the color palette of classic slate, these roofs offer a practical, versatile, and visually captivating option for diverse architectural projects.

Understanding Synthetic Slate Roof Costs: A Detailed Breakdown

A synthetic slate roof offers the advantage of being composed of composite materials such as plastic, rubber, or polymer, meticulously engineered to mirror the aesthetic of natural slate. When contemplating a slate roof for your home, it’s essential to unravel the aspects that influence the final expense,  including the materials used, labor, roof dimensions, slate type, style variations, and intricacies of the installation process. Delving into these factors provides a comprehensive understanding of the components that contribute to the overall cost. 

1. Roof Size: Scaling the Costs

The size of your roof wields a significant impact on your slate roofing budget. Professional roofers often determine costs based on the size of the project. Larger roofs require more labor and materials, which can substantially affect the overall cost. Roofs are measured in squares, with one square equaling 100 square feet. On average, slate roofs cost around $1,500 per square, whereas synthetic slate roofs can vary from $700 to $1,000 per square. Here’s a breakdown of synthetic roofing costs based on roof size:

Roof Size (square feet)
                                              Roof Squares Required                                  Average Roof Cost

2,75028$28,000 – $84,000
300030$30,000 – $90,000 

2. Type of Slate: Natural vs. Synthetic

The type of slate you choose plays a pivotal role in cost determination. Natural slate can range from $10 to $80 per square foot. Alternatively, synthetic slate and hybrid options offer budget-friendly alternatives starting at around $5 per square foot.

Here’s a detailed comparison table between natural slate and synthetic slate for your reference:

#3. Hardness and Longevity

Slate hardness impacts both durability and cost. Hard slate, which can last up to 200 years, comes at a premium due to its exceptional resilience and fire resistance. Soft or synthetic slate, though easier to install, has a lifespan of around 125 years and is relatively more affordable.

#4. Style Variations

Slate tiles come in various styles, each with its own pricing nuances. Standard tiles, characterized by their uniform shape and color, are generally the most cost-effective option. However, patterns, multicolored tiles, and textural variations may entail an additional cost.

#5  Removal cost

The cost of removing a synthetic slate roof can vary depending on a number of factors, including the size of the roof, the type of synthetic slate, and the disposal method. In general, you can expect to pay between $2 and $5 per square foot for synthetic slate removal.

Here is a table breaking down the removal cost for synthetic slate:

Size Of Roof (Square Feet)Cost Per Square FootTotal Cost

The cost of disposing of synthetic slate also adds to the total cost of removal. If you are disposing of the synthetic slate in a landfill, you will typically pay between $20 and $40 per ton. If you are recycling the synthetic slate, the cost will be lower.

#6  Labor: The Foundation of Craftsmanship

Labor constitutes a substantial portion of roofing costs, typically accounting for about 70% of the total expense. Installing slate demands specialized skills and time-intensive efforts. Unlike other roofing materials, slate installation can take between 10 and 12 hours per square. This translates to a significant amount of labor for your entire roof. 

Ensuring the roofer is licensed and insured safeguards your investment against unforeseen circumstances, ensuring your project is completed smoothly.

In essence, understanding the nuanced elements of the cost of a slate roof equips you with the knowledge needed to make informed decisions. As you embark on this roofing journey, remember that every aspect contributes to the durability, aesthetics, and long-term value of your synthetic slate roof.


If you’re replacing or installing a new roof, synthetic slate is a great option. While the initial investment may be steeper compared to traditional roofing materials, keep in mind a synthetic slate roof requires less maintenance and lasts up to five times longer than materials like asphalt shingles. In the long run, you’ll be happy you chose synthetic slate for your roof.
