Synthetic shake and shingles are polymer-based material, or a combination of plastic and rubber. They are used on roofs where homeowners desire the classic look of wood or natural slate, with the added benefits from the synthetic blends.
Synthetic roofs are relatively new to the residential roofing market, first arriving in the early 1990’s. Their durability, environmental friendliness and affordability have all contributed to their rising success.
For an average 2,000 sq.ft., non-complex, single-story roof, it will cost between $7.50 and $11.50 per sq.ft. installed. This results in an average total price range of $15,500 to $23,000. If the existing roof needs to be torn off and disposed off first, this can cost an additional $2,000 to $3,500 more.
A complex roof with multiple angles, dormers, and valleys, or steeper pitch than average would add to the complexity of the project and cost more as a result.
Cost of Materials
Composite shingles and fake composite slate cost virtually the same. Formation is done via a molding process to ensure it resembles wood or stone, as the case may be.
The material is fairly light at about 1.25 pounds per tile, so essentially all roof types can handle such installation. The tiles can easily be cut on-site with a utility knife and are attached as simply as using a nail gun.
An asphalt shingle roofer ought to have the skills to properly install synthetic shake and shingle roofing.
Breaking Down Costs Into Specific Examples
With any home improvement project being handled by qualified professionals, it is in your best interest to get more than one quote, or preferably between three and seven.
The quoted figures they give you will either be total installation charges (one price for everything) or they’ll ideally itemize each cost so you can better compare their rates to the competition. For the example below, we ballpark certain figures as particular items, like building permits and disposal fees vary by region.
Composite Shingle Roofing: 2,000 sq.ft. (20 roofing squares) = $18,000 (includes materials and professional installation)
Tear Off Existing Roof: $1,500
Disposal fees: $500
Additional Materials: Flashing, fasteners, underlayment, etc. = $550
Building Permit: $350
Total Project Cost = $20,900
Factors That Contribute To Overall Cost
While material costs are roughly the same between composite shingles and fake slate, the material costs will be based on manufacturer and distributor pricing.
Normally, contractors buy product at wholesale through established distributors. There are a number of manufacturers in the marketplace, and the popular ones are:
- CertainTeed (under their Symphony line)
- DaVinci Roofscapes makes synthetic slate, also known as fake slate.
- Enviroshake also produces synthetic shake (though crosses over into other types, despite their brand name).
