Polycarbonate roof vs Aluminum-pan roof
Patio cover roofing comes in two primary categories — multi-wall polycarbonate that admits filtered light, or insulated aluminum-pan panels that block light entirely. The choice shapes the room's character, temperature, and acoustic profile.
Polycarbonate roof
Translucent, light-admitting
Aluminum-pan roof
Solid insulated, light-blocking
How they stack up.
| Dimension | Polycarbonate roof | Aluminum-pan roof |
|---|---|---|
| Light transmission | 40–60% filtered light | 0% (opaque) |
| UV protection | >99% with UV-stabilized grade | 100% (opaque) |
| Heat under cover | Warmer in direct sun | Cooler |
| Rain noise | Audible drumming | Quieter; sound-dampened by insulation |
| Lifespan | 8–10 yr (entry); warranty period for UV-stabilized | Lifetime warranty on Renaissance |
| Best for | Shaded yards, dappled-light spaces | Direct-sun yards, year-round seating |
Polycarbonate is the right call for shaded yards under mature trees where a solid roof would feel cave-like. Also right when the homeowner wants the cover to read as a sunroom rather than a solid patio.
Aluminum-pan is the right call for direct-sun yards where heat gain matters, and for households that want a quieter rain experience and a long-life roof that doesn't yellow.
