Composite Roofing: Pros, Cons, and Cost
Composite roofing gives a house the look of natural slate or cedar shake without the weight, the fragility, or the upkeep the real thing demands. For a lot of homeowners in the Southeast, it turns out to be the practical version of the roof they actually wanted. This page covers what the material is, how it performs in Georgia, Tennessee, and Alabama, what it costs, and when the premium over asphalt is worth paying.
What Composite Roofing is Made Of
“Composite roofing” isn’t the same thing as traditional roll roofing, even though the two terms get mixed up online. Roll roofing is a mineral-surfaced asphalt product usually installed on sheds, garages, and other small structures. Composite is a different product entirely: individual shingles or tiles molded from a blend of polymer resin, rubber, and plastic, engineered to replicate the look of traditional shingles, natural slate, cedar shake, or clay tile.
Manufacturers cast their molds directly from real slate and wood shake to capture the texture, grain, and shadow lines of the original, down to details like chisel marks on slate-style profiles. From the ground, most homeowners can’t tell the difference.

The Trade-Offs of Composite Roofing
The material solves several problems that natural slate and cedar shake create, and it brings a few of its own. Most of it comes down to a single trade-off: you pay more at installation to buy your way out of decades of maintenance. Whether that math works depends on how long you plan to stay in the house and what the roof has to survive in the meantime. Here is what the material earns and where it costs you.
What Composite Does Better than the Materials it Imitates
- Composite shingles have the look of slate or cedar shakes and weigh a fraction of natural slate or tile, so most roof structures can support them without any additional framing.
- Most composite products are built to survive hail and carry a Class 4 impact rating, the highest hail-resistance rating under the UL 2218 and FM 4473 standards, meaning they can take two direct hits from a 2-inch steel ball dropped from 20 feet without cracking.
- Georgia, Tennessee, and Alabama are on several major insurers’ list of states offering a discount for Class 4 impact-resistant roofing, commonly in the range of 5 to 15% in moderate-hail states like ours. You should confirm the exact number with your agent, since it varies by carrier and policy and some offer up to 25% savings.
- Unlike real cedar shake or wood, it doesn’t rot, crack, curl, or feed the algae and moss growth that thrive in a humid climate.
- Most composite products are rated for 40 to 50 years, roughly double what a standard asphalt roof delivers in this climate. For many homeowners that means buying one more roof in a lifetime instead of two or three.
Where Composite Asks More of You
- Expect to pay roughly 2 to 3 times what a standard asphalt shingle roof costs. The cost section below has the per-square-foot numbers.
- Not all composite products are built the same. Lower-grade shingles can fade or degrade faster than premium ones, so the brand and product line matter as much as the material category.
- Unlike asphalt, installation is more labor-intensive, laying each piece individually takes longer and demands a skilled crew with material-specific expertise.
- Cold-weather cracking risk isn’t much of a concern in our climate, but very cold snaps can make some composite products more brittle.
None of that is a dealbreaker. It just means the product and the installer matter more here than they would with standard asphalt. That is exactly what an inspection and consultation are for.
Where Composite Roofing Performs Best
Composite actually suits this climate better than several of the natural materials it imitates. It shrugs off the humidity, moisture, and algae growth that give real wood shakes trouble here. It tends to be the right call on:
- Older homes whose framing was never built to carry the weight of real slate or tile. You get the look without the structural upgrade.
- Properties where hail is a genuine concern. Georgia, Tennessee, and Alabama’s moderate hail risk, plus the potential insurance discount, makes a Class 4 product a financial case and not just an aesthetic one.
- Homes where the wood shake look is the goal but the upkeep is not. Synthetic slate and synthetic shake profiles hold their appearance and performance through our summers without the maintenance cycle real wood requires.

What Does Composite Roofing Cost?
Composite typically runs $6 to $14 per square foot installed. Where a project lands inside that range depends mostly on profile and manufacturer, since shake-style products generally cost less than slate-style ones. For comparison, standard asphalt shingles run roughly $3 to $5 per square foot installed.
| State | Avg. Roof Surface Sq. Ft. | Basic Composite Shingles Range (~$7–$12/sq. ft.) | Composite Shake & Tile Range (~$10–$18/sq. ft.) | Premium Composite Slate Range (~$15–$25/sq. ft.) |
|---|---|---|---|---|
| Georgia | ~2,000 | ~$14–$24K | ~$20–$36K | ~$30–$50K |
| Alabama | ~3,200 | ~$22–$38K | ~$32–$58K | ~$48–$80K |
| Tennessee | ~2,500 | ~$14–$36K | ~$20–$54K | ~$30–$75K |
The premium comes from the product and the labor together. The shingles themselves cost more than asphalt, and because each piece is set individually rather than laid in large mats, the crew spends longer on the roof. That is also why installer experience matters more with this material than it does on a standard asphalt job.
If the upfront number is the sticking point, our financing options can turn it into a monthly payment that fits your budget.
