What Are Synthetic Slate Shingles Made Of?
Synthetic slate shingles are a relatively new roofing material that is made from a mixture of fiberglass, hemp fibers, post industrial plastic, recycled paper products, polymers, and a number of others, depending on the specific blend that a manufacturer uses.
These synthetic shingles are known as “composite shingles” not to be confused with composition shingles, which are really asphalt shingles.
As the name “composite” implies, each composite roofing product can actually be made from very different materials, which will then impact its durability, longevity and weather resistance.
When you research composite slate shingles its very important to check out the actual composition of each product, to ensure you are getting a top quality roof.
How Much Does A Faux Slate Roof Cost?
Compared to other popular roofing materials, synthetic slate shingles fall in the middle of the price spectrum.
Composite slate shingles or tiles cost $5.25-11 per square foot installed, including all materials and professional labor. On a 2000 sq. ft. roof this is equivalent to $10,500 – 22,000. Most homeowners report spending $7.75-8.5 per square foot or $15,500 – 17,000 on a 2,000 sq. ft. composite shingles roof.
Material prices range from $350-475 per square. If you use copper for valleys, drip edge, pipe boots, and flashing, then the cost can go as high as $525-600 per square.
By comparison you would spend at least $35,000 on a natural slate roof of the same size. Total installation cost for a real slate roof starts at $1,650 per roof square and can go as high as $3,000 per square. (1 roof square = 100 sq. ft.)
Pricing for composite slate shingles is most similar to metal roofing. Compared to asphalt roofs, synthetic slate shingles and tiles cost 2 to 3 times as much.
Keep in mind that your total roof installation cost can vary greatly depending on the following factors:
– complexity of your roof design
– number of stories in your house
– ease of access to the roof
– local professional labor rates in your area
– roofer you hire
For example, on both the West and East Coast, in most cities and suburbs the price for professional roofing installation can be 20-25% higher than the cost of the same job in less affluent areas, such as the Midwest, Texas, etc.
Moreover, even within the same area, some roofing pros can charge a lot more money for their work, depending on the size of their company, years in business, overhead costs and many other factors.

7. Extensive color options: the colors are formulated from a pallet of 24 earth tones. Custom blends are also available.
2. StoneCrest Slate Shingles
StoneCrest Steel Shingles, manufactured by Tamko, masterfully imitate the look of slate, but unlike a true composite roof, its actually made of metal.
These metal shingles rival real stone in terms of durability and longevity.
This makes StoneCrest Shingles ideal for homeowners who live in the snow country and whose primary concern is weather resistance.
Tamko metal shingles are manufactured with heavy gauge G-90 steel, and are double stamped for exceptional beauty and strength.

5. Eco-friendly: Tamco manufactures its shingles from from 37% to 89% recycled content. At the end of its service life, this roof is 100% recyclable.
3. Ecostar Roofing
Majestic is a beautiful composite slate shingles roof, manufactured by EcoStar. It is an injection molded material, made primarily from recycled rubber. This roof is ideal for environmentally conscious homeowners.

2. Half the cost: Majestic tiles cost from $390 – $430 per square (material only). This is at least half the price of natural slate, which ranges from $650-750 per square.
3. Easy installation: the rubber-based composition of the material enables a contractor to simply nail each tile to the roof deck. This is a lot less labor intensive than having to nail through pre-drilled holes in slate, and possibly breaking some tiles in the process.

This means that the color goes all the way through, does not require additional paint application, and will not chip over time.
Where To Buy A Faux Slate Roof
In general, there are very few manufacturers that produce composite roofing, and synthetic slate roofing in particular.
Usually, big roofing manufacturers such as GAF, IKO, Owens Corning do not bother with these niche roofing materials, because the market share is too small.
Another, more important reason is the potential problems that can happen with composite roofing depending on the materials formulation and manufacturing process that is used.
Keep in mind that producing a high quality, long lasting composite slate roof is expensive, so don’t expect any bargains on this type of roofing material.
If you are getting a quote for synthetic slate that is similar to the price of high-end asphalt shingles, you should be very suspicious of the quality of this product.
Did You Know? In the last two years, two big building manufacturers discontinued their popular synthetic slate roofing lines without disclosing the reasons for this decision.
One of them is Symphony Slate by CertainTeed which has been discontinued since 2019, but there is still a lot of information floating around about this roofing product on various roofing and home improvement blogs, because it was so popular.
Today, CertainTeed offers Matterhorn Metal Roofing Tiles that replicate the look of slate while offering all the perks of metal roofing.
Another is PlyGem Slate and Cedar Shakes roofing. They discontinued both these products in the summer of 2019.
