The short answer
Synthetic composite shingles use engineered polymer to mimic slate or cedar shake at a fraction of the weight. They typically carry Class 4 impact ratings and 40 to 50 year warranties, at a cost between premium asphalt and metal.

Where it performs
- Slate or cedar appearance without the weight
- Class 4 impact rating in most lines
- Much longer life than asphalt
- No structural reinforcement required
- Class A fire assemblies, which matters on rural lots
The trade-offs
- Costs well above asphalt
- Fewer installers are experienced with it
- Color and profile selection is narrower
- Long term field performance has less history than asphalt or metal
What we install
Worth considering where appearance matters, weight rules out real slate or tile, and you want hail performance better than standard asphalt.
